[Shane Burrell] came across a Nortel GPSTM and re-purposed it as a 10MHz reference for his lab. The GPSTM is designed to slot into a backplane, most likely for telecoms applications. So [Shane] needed to hack the board to run from a 48v PSU. Once powered up, it was relatively easy to interface as the card appears to contain the well known Trimble Thunderbolt module and is compatible with its software.

We’ve covered frequency references before and they can be a valuable addition to a lab. On the back of most scopes, spectrum analyzers and function generators you’ll find a 10MHz reference input allowing the user to supply a reference more accurate than that generated internally. Not only is an external reference often more accurate, it also allows you to keep all your equipment in sync with a common reference, which can be particularly important in some measurements. While some hackers opt for Rubidium sources, the GPS disciplined temperature-controlled oscillator in the Nortel unit should provide a nice stable reference.

A word of warning to [Shane] though, get sucked into hacking frequency references and you may become a time nut finding yourself climbing mountains to test the theory of relativity.

Electronics, software help cars cruise design crossroads

Future automobile designs announced at the Detroit Auto Show combine the technology of different platforms with futuristic design features to create a new driving experience
Anna Allen, Staff Editor

Detroit, MI--The future has arrived. Thanks to the efforts of design teams from General Motors (GM), Daimler-Chrysler, and Ford, concept cars are exploring new roads. SUVs, minivans, sports cars, coupes, and sedans are crossing paths, creating a new entry of vehicles, a metamorphosis if you will.

Among the concept introductions at the North American International Auto Show:

Visual interest. General Motors (GM) introduced five cars at the show, they include the Pontiac Aztek, Buick Cielo, Oldsmobile Recon, Cadillac Evoq, and Chevrolet Nomad. To design these cars, engineers are using Alias software's 2D digital sketching, paintbox, 3D digital modeling, and 3D visualization tools.

Each brand has its own design center that houses exhibits to inspire new automobile concepts. Kate Zak, a developer of brand center characters, comments that GM wants its engineers to know what the focus is, what it feels like.

Such exhibits include Speedforms, a generic sculpture of the individual brands' shape that helps engineers maintain the concept's focus and the model's theme. A glass case houses the brightest, boldest products, such as the latest Nike sneaker, which influence car design and keep engineers aware of consumer wants and needs.

Tom Peters, one member of the Pontiac Aztek design team, recalls going shopping with his kids and being captivated by a yellow/gray jacket. Products such as this gear, says Peters, stimulate a visual interest and incorporate materials to attract the consumers. He comments that sports bikes are another eye-catcher, especially those that feature exposed structural elements.

It's products and designs such as these that the design teams adopted for Pontiac Aztek, which combines the basic elements of an SUV, sedan, and van into one automobile. The Aztek, says design team member Phil Kuchera, is "in the hunk look, with a dual-port exhaust. Its profile is most dominant, a whole new animal, not a Clint Eastwood but rather an Arnold Schwarzenegger."

This four-door hatchback seats four passengers and features a 3.4l V6 200-hp engine with 225 lb ft of torque mated to a four-speed automatic transmission. This combination makes it possible to tow up to 3,500 lb--enough power to trailer not one, but two SeaDoo personal watercraft.

The car offers front-wheel drive with traction control and rack-and-pinion steering. Other features include MacPherson fully independent front struts, open-section twist-axles with integral stabilizer bar, and gas shocks with coil springs in the rear.

Inside, the titanium and textured-leather instrument panel features a fully exposed floating-instrument cluster pod with round analog gauges peer out of a titanium face plate.

The pod features Delphi Delco Electronic System's Ultra-Lite technology that uses a thin sheet of acrylic to efficiently channel light to the yellow primary display graphics. At night, the display takes on a 3D look.

The panel also features a driver information center with built-in heads-up display and multifunction LCD. The LCD screen delivers driver information center messages, time and radio-station readouts, and navigational information.

The main monitor also controls Pioneer's premium visual audio system. This system features a radio with CD changer control, two LCD displays, DVD, six-disc multi-CD changer, cordless remote control, and 10 speakers. The door speakers feature Pioneer's low-profile Kevlar(R) cone and neodynium-magnet circuit technology for loud, clear sound.

The Pontiac Aztec is is just one example of how GM is moving design. Another is a new spin on today's convertible.

"A no-compromise vehicle." That's how the Buick Cielo's design team described this concept, which they say provides the comfort of a sedan with the with the open-air enjoyment of a convertible.

This concept is designed from a primarily math-based process that involves extensive use of computers, 3D modeling, computer sketches, rendering, and production of a foam, not clay, model. This four-door convertible seats five and features a 3.8 liter supercharged V6 engine with four-speed auto transmission.

The Cielo features wide-opening doors, a dual head-up display, voice-activated systems (such as a retractable roof that is either voice or button operated), air bags (mounted in the roof rails), and a shift-by-wire roof (a sunroof that opens to varying degrees). The ignition is keyless.

Cielo's two roof rails run between the front of the passenger compartment and the rear end, strengthening the overall body and allowing use of three hard roof panels that slide into the trunk when the driver wants the top down. When the convertible top is up, the roof rails provide increased body stiffness and reduce noise and wind intrusion.

The four doors are power-operated and hinged at the front and rear pillars, opening at the center pillar. Articulating hinge mechanisms allow the doors to open wide. Recessed rockers and door sills Boost access to the car. And, the rear seat folds down.

A hybrid hybrid. At Daimler-Chrysler, designer's are using Visio and CATIA to create their futuristic concoctions. And once again, commercial products are driving some of the design considerations.

Chrysler's concept cars also address the need to increase fuel efficiency or look at alternative operating methods. The Citadel blends a sport sedan with an SUV and mixes in a futuristic performance powertrain.

"The Citadel is a hybrid-hybrid, a new breed of crossover vehicle. It provides the driving passion of the Chrysler 300M with ample cargo room," says Neil Walling, vice president of advanced design and exterior large-car, small car, and minivan. While Citadel is a hybrid among market segments, it is also a hybrid of powertrains; that is, it draws from two different sources.

"It's a performance hybrid," explains Bernard Robertson, senior vice president, engineering technologies. "The Citadel gives you V-8 power with V-6 fuel economy." A gas engine propels the rear wheels and electricity drives the front wheels. "We use the hybrid concept to recover energy normally lost when braking, while providing all-wheel -drive."

The rear wheels move by way of a 3.5l V-6 and the front wheels receive additional power from Siemens Automotive electric motors, which have been used on electric vehicles, similar to the Dodge Caravan/Plymouth Voyager EPIC electric minivan. The V-6 generates 253 hp and the electric motors add another 70 hp.

Other highlights of the Citadel include dual-power sliding rear doors and a retracting cargo door that slides under the floor. The B pillar moves with the rear door as it opens to maximize accessibility.

The Citadel has 2 inches more ground clearance and is 3 inches taller than the Chrysler Concorde. It has 20 x 3 ft of storage room, as compared to the 18.7 x 3 ft. for the Concorde.

Instrument panel design is influenced by high-end sports watches such as Chronoswiss and Blancpain. Hand-sculpted chrome is used for the indices on the gauges face. Other features include handmade chrome bevels around the odometer and clock--which carries into the steering wheel, door-control modules, pedals, and the folding tray table on the backside of the front seats.

As we round the corner to the millenium, car design races full speed ahead. Today's roads are the track for a new breed of vehicles. Which concepts will move forward and what else will emerge? That is in the hands of the designers, the vendors, and the tools--we'll have to wait and see.


Here's some other concept cars introduced at the Detroit Auto Show:

Flex ring rinses out washer abuses

Newton, IA--Maytag Corp.'s washing machines are noted for their reliability and maintenance-free performance. Therefore, it seemed only natural for the quality-conscious engineers at Maytag to team up with a product development group at a major producer of elastomers for ideas on how to make its washers even better.

The project: Build a new multi-cavity tool for a flex ring that makes up part of the torque-sensitive mechanism in the agitator of the vertical washer. The previous material did not provide the high stiffness characteristics needed to adjust the amount of agitation for varying load sizes. However, no standard-grade thermoplastic polyurethanes Maytag tested fulfilled the need.

Maytag engineers conferred with personnel from Pella Plastics (Pella, IA), the part's producer, and with BF Goodrich (Cleveland) development engineers to come up with a solution. The team quickly identified the properties needed to meet both process and performance objectives of the new flex-ring design. Then product development engineers at BFGoodrich's IDEA Center turned these requirements into reality by developing Estane(R) 58151, a high-stiffness, durable, 70 Shore D thermoplastic polyurethane that offered excellent hydrolytic stability.

System cools off computer processor

West Columbia, SC--Fast processor speeds generate heat, which means something's got to cool everything off. That's why Compaq turned to KryoTech Inc. to provide the cooling system for the KryoTech/Digital 767 Personal SupercomputerTM, which runs at 767 MHz.

KryoTech's patented -40C cooling system was developed specifically for use with the Alpha Workstation, according to Scott Spears, product marketing manager for KryoTech. "Each cooling system is specifically designed for use with the specific processor," he says.

The Alpha Workstation works with mechanical, CAD, or CAE applications. It also has been used in research and in custom design applications. "People use it when they need as much number-crunching power as they can get out of one processor," Spears notes.

The cooling system is a standard vapor-phase refrigeration one. It uses a freon alternative coolant, which is environmentally friendly. The system pumps liquid coolant to the evaporator, which is in contact with the workstation CPU inside the KryoCavity.

The KryoCavity is a hermetically sealed and specially insulated device that holds the CPU and maintains the electrical connection with the motherboard. A pressure decrease inside the evaporator causes the liquid coolant to change into a gas, and this phase change pulls the heat off the CPU, Spears says.

KryoTech came to Compaq, which was then Digital, with the idea for a thermal cooling solution. "We work on the premise that as chip technology progresses, chip size doesn't change, but chip power does, and they produce more and more heat," Spears says.

"Active cooling systems like we promote not only dissipate the heat but help the user get more power out of the chip."

The cooling system goes to -40C, and at that temperature, the system provides a 30% increase in processor speed. KryoTech is working on a system that gets colder than that. "At -120C, you double the speed of the processor," Spears says.

People at home sometimes also overclock their computers, tuning their motherboards and turning up the speed of their processors. This gives the user extra power and speed, but generates high heat, which can cause damage to the machine. "They use any and every means they can to cool them off, including putting their entire computer in the refrigerator," Spears says. "We've heard about all sorts of strange methods."

Elastomer prevents process contamination

Fremont, CA--HTM Technology Corp. believes staying ahead in the computer industry demands only the best manufacturing techniques and technology. That's why, as a leading provider of thin-film disks for high-capacity disk drives in PCs, network servers, and workstations, the company must control contamination during processing. It's also a major reason why HMT recently replaced fitted fluorocarbon-coated elastomer seals with perfluoroelastomer parts in its electro-less nickel plating production equipment.

Supplied by Pan Pacific Supply Co. (Concord, CA), the parts, made by DuPont Dow Elastomers (Wilmington, DE) from Kalrez(R), have saved HMT an estimated $770,000 per year in reduced downtime, while improving safety on the production line.

Kalrez combines the sealing force and resilience of an elastomer with the chemical inertness and thermal stability of Teflon(R) fluorocarbon resin to create an extremely durable seal that can survive under severe caustic conditions. It contains no active hydrogen atoms in its polymer backbone, giving it the ability to withstand a wide range of chemicals, yet remain thermally stable at temperatures as high as 600F.

In the electro-less nickel plating process, nitric acid (40% at 125F) removes nickel build-up on the side of the plating tank. For HMT, the harsh chemical environment disintegrated previously installed fluorocarbon O-rings used in various valves and fittings. Result: The company had to manually change the seals at least once a month.

HMT replaced the fluorocarbon O-rings with Kalrez in one of its seven plating tanks in December 1995. After a successful two-year trial-and-error campaign, the company fitted the six remaining tanks with the material.

"Degrading of the fluorocarbon O-rings would begin almost immediately, resulting in equipment contamination, acid leaks, and production loss," says Brian McIntyre, HMT's equipment engineering manager. "Since the switch to Kalrez seals, we're replacing seals about once every two years."

Mobile phones withstand tough environments

Nashville, TN--Given survey results showing that people at work spend at least two and a half hours a day away from their desks--costing businesses over $3 billion a year--Northern Telecom (Nortel) decided to develop a more-durable, less-costly wireless phone. The result: the Companion C3050 phone with a tough phone-covering accessory made of thermoplastic rubber.

The companion phone series enables mobile, wireless communications within the workplace, increasing worker productivity, improving customer service, and reducing costs. Whether a person is climbing a ladder or just in an office down the hall, the phone's custom-designed Rugged Protector accessory allows the user to clip the phone on for greater comfort and freedom of movement.

Design Workshop (Ottawa, Canada) was the industrial designer for the holster of Nortel's earlier Companion C3020 series of phones, designed primarily for office use. The new phone series needed to withstand the tougher conditions of an industrial environment, so Nortel asked Design Workshop to incorporate the Rugged Protector in the new models.

In turn, Design Workshop contracted the molding process to ITW Plastiglide (Toronto, Canada), which had the insert molding and tooling expertise needed for the accessory's design. The application presented both companies with a challenge: Make an intricate, yet protective and durable cover that allows the user to operate the phone while still in its holster.

"The C3050 was more advanced and contained more delicate parts than the earlier series," notes John Tutton, partner, Design Workshop. "We needed to make sure we selected the right grade of material that would meet critical performance and visual requirements."

Tutton used Santoprene(R) rubber, supplied by Advanced Elastomer Systems L.P. (AES, Akron, OH) as the base material for testing and comparing other potential material candidates. The material they sought had to have the ability to form the phone's intricate features, resist abrasion, and still provide adequate impact protection.

"We went through a long list of thermoplastic elastomers when trying to come up with the right material, beginning with Santoprene, since its properties made it the top contender from the start," Tutton recalls. "After conducting the tests, we ended up choosing a standard 75 shore A grade of Santoprene as the best material."

National Manufacturing Week showcases diverse products

Chicago--From March 15 through 18, engineers will have the chance to experience "America's #1 Source for Today's Industrial Solutions" at National Manufacturing Week. The show, which drew more than 60,000 attendees last year, is sponsored by the National Assn. of Manufacturers.

Manufacturing Week consists of the National Enterprise IT, National Industrial Automation, National Plant Engineering MRO and Management, and the National Design Engineering shows and conferences.

A new development this year in the National Design Engineering part of National Manufacturing Week is the Motion Hall, which is an entire hall devoted to motion-control products.

Last year, 2,100 exhibitors were on the show floor. Two companies who are returning this year are Cutler-Hammer (Cleveland, OH) and Intergraph Computer Systems (Huntsville, AL).

Cutler-Hammer will be celebrating its five-year anniversary as a company, and will be showing "best-in-class solutions, and how we will be taking them into the future and impacting manufacturing processes," says Paul Handle, marketing communications manager. The stage show, which featured music and dancers that transitioned into a speaker last year, will return, and will be "bigger and better, informational and entertaining," Handle adds.

"We're going to blow everyone away," he says. "The show is important to us, and we feel lucky to be a part of it. You'll have to see it to believe it."

Cutler-Hammer will also be showcasing several new products, including the SM Series photoelectric sensors. The series uses a microprocessor-controlled system called TargetLockTM to help users speed up the installation process and Boost sensor reliability, the company says.

Another product Cutler-Hammer will be showing in its booth at National Manufacturing Week is the SV9000 line of drives, which are available from 0.75 to 1,100 hp and 200 to 690V. The drives are consistent across all frame sizes, Handle says.

In the Intergraph Computer Systems booth, watch for the latest Intel/Windows NT-based TDZ-2000 visual workstations targeted at MCAD professionals. Intergraph will also show a variety of mechanical CAD applications, including Pro/ENGINEER and SolidWorks, according to Marla Robinson, media relations manager for Intergraph. The TDZ-2000 workstations feature Intense(R) 3D Wildcat graphics, which, Robinson adds, are the fastest graphics on Windows NT.

In the Design News booth, be on the lookout for web site demonstrations and several innovative products that have appeared in the magazine's pages last year.

Unix workstation breaks memory bottleneck

Palo Alto, CA--Hewlett-Packard has broken a memory bottleneck with its HP Visualize Model C360 workstation, which it touts as the world's fastest desktop workstation. Based on HP's new 367-MHz PA-8500 64-bit microprocessor, the C360 achieves performance specs of 26.0 SPECint95 and 28.1 SPECfp95, as measured by HP.

Its performance numbers are significantly better than those of its predecessors, the C200 and C240, which use previous versions of the PA-8000 family. Performance on mechanical design applications is up to 77% faster, says Barry Crume, product marketing manager for HP's workstation division. But the only hardware difference is that the C360 has its primary (or first-level) cache memory integrated on the PA-8500, and the C200 and C240 primary caches are the motherboard. Other than that, the three machines are practically identical.

HP engineers were able to integrate 1.5 Mbytes of primary cache on the PA-8500 chip by using a 0.25-micron manufacturing process instead of 0.33 micron. (The smaller geometry also increased the chip's frequency.)

Other advantages of on-chip primary cache include:

Bus between on-chip primary cache and CPU runs at CPU clock rate (367 MHz for PA-8500), which is much faster than for off-chip cache.

The C360 was designed for engineers doing computationally intensive work. A C360 with VISUALIZE-fx2 graphics, 256 Mbytes of RAM, a 4-Gbyte hard disk, and 21-inch monitor costs $24,500.

Earlier detection, easier cure

Rick DeMeis Associate Editor

Skaneateles Falls, NY--A direct result of medical equipment supplier Welch Allyn's ongoing education atmosphere is the technology in its frequency-doubling Visual Field Analyzer (see DN 1/18/98). Here, a Medical Products Operation advanced technology manager attended a conference and met the Australian researcher who formulated the concept. The company brought the technology in house for development in conjunction with university and industry design partners. Extensive, targeted training in electromagnetic interference (EMI) and susceptibility brought one engineer up to speed for his portion of the design. Finally the product was implemented and introduced via the company's cross-functional teams.

The Visual Field Analyzer looks at eye function for advanced warning of glaucoma. It is more sensitive and provides fewer false positives and negatives than the common methods of eye-pressure measurement, such as the "air puff." Previously, high accuracy was possible only using equipment costing four times as much (up to $25,000), the company asserts. Testing would take 15 min/eye as opposed to 45 sec now.

The patient looks at a series of bars that vary sinusoidally between light and dark. Between 25-28 Hz, a set of retinal nerve cells, that happen to be the first degraded by glaucoma, produce an optical illusion of twice as many bars. Determining the contrast level where the bars are just barely visible correlates to a variety of eye diseases for earlier detection and easier cures.

Killexams : The Wow! factor is alive and well

Kanata North remains on the cutting edge when it comes to the next generation of semiconductor technologies. And why wouldn’t it be? That pedigree is rich and runs deep, all the way back to Bell Northern Research and the old Mitel Networks. 

Take GaN Systems, co-founded eight years ago by CTO John Roberts and President Girvan Patterson. Their resumes, and those of others on the management team, are a who’s who of the big local names in the industry through the ’90s and the 2000s. 

That’s no accident. GaN’s potentially game-changing gallium nitride switching and power conversion portfolio was prototyped in the National Research Council of Canada’s own test foundry acquired from Nortel Networks. When it came time to build and expand GaN’s team, the founders had no problem finding a great pool of proven local talent from which to draw. 

Heritage of the area 

But it isn’t just talent – a corporate culture that fosters open creativity has also carried over from those old days. 

“That’s a heritage of the technology sector here that’s still alive and well,” Patterson said. 

Sidense Corp. is another thriving player that’s taken advantage of creative culture and talent to grow its global clout in the vast market for embedded non-volatile memory. Its team pedigree includes Chipworks, MOSAID Technologies, Mitel Networks and ATMOS Corp. The company has been snapping up good memory people wherever it can find them. 

“If you’re a good circuit designer, you’re going to find employment here,” said Tomasz Wojcicki, VP of Customer Engineering Support. 

Even semiconductor multinationals that set up shop in Kanata North are looking for more than just another satellite office. They’re looking for a specialized local team to tackle hard problems no one else can. 

Rocket science 

Take Taiwan Semiconductor Manufacturing Company Limited. TSMC has grown over the past two decades from a startup in chip manufacturing into the world’s largest independent foundry. Roughly half of the chips found in mobile phones today are manufactured at TSMC. 

TSMC’s Ottawa team works on next-generation memory compilers, high-speed interconnects, and perhaps most impressive of all, test systems that are embedded on the chip itself. 

“We have here one of the top groups in the world that is working on stuff that no one else has ever seen,” said Cormac O’Connell, Director of TSMC’s Ottawa Design Centre. “We’re literally doing rocket science here.” 


- Ottawa’s semiconductor industry (and you might even say Canada’s) began in 1969 when Nortel Networks forerunner Northern Electric created Microsystems International Ltd. (MIL). MIL produced one of the world’s earliest microprocessors, the MIL MF7114, and a series of early microcomputers using this chip. 

- MIL was also the place where future serial entrepreneurs Terry Matthews and Michael Cowpland met. The rest, as they say, is history. 

- Today’s chips can contain 10 billion devices, where a single atom out of place can have a dramatic impact on performance. What’s on a chip these days needed a whole server room 20 years ago. 

- GaN Systems’ gallium nitride compound chips replace conventional silicon-based electronic switches that just can’t meet spec for speed, temperature, voltage or current. Efficiency-improving applications range from high-performance auto engines and industrial to making your TV even thinner and getting rid of that brick on your laptop power cord. 

- As an independent foundry for hire, TSMC makes chips for fabless electronic companies so they don’t have to spend billions to set up their own foundries. This enables them to build products and compete against the likes of Samsung or Intel – companies that can afford to fabricate their own chips used in their branded system products. 

- Sidense Corp. is making waves with what might seem like an old, quaint technology – one-time programmable memory. But that supposed “limitation” provides one significant benefit – a tough layer of added security as more and more devices become connected through the Internet of Things.

Killexams : Securing Smart Cities from the Ground Up

Smart City network infrastructure demands a proactive approach to find vulnerabilities before hackers find them

Smart technology continues to change how people live and interact with the cities around them. While the full value of a connected city evolves – one that leverages innovations powered by artificial intelligence and machine learning – cybersecurity stands as one of its greatest challenges. 

The Smart City Conundrum

While the promise of Smart Cities provides municipalities and inhabitants with the efficiency and value of “smart” services, it also creates a cybersecurity challenge. Each connected component – from devices to the network infrastructure – offers a potential entry point for hackers to steal data, damage systems, and gain access to information they shouldn’t have. 

Smart City ecosystems could be filled with tens of thousands of Internet of Things (IoT) devices communicating over public network infrastructure. In order for the Smart City to succeed, each IoT device must be low power, exhibit excellent performance, be able to withstand interference, and be reliable. They’ll operate with the free flow of data between devices and the network infrastructure that connects them. How do Smart Cities ensure that each part of the Smart City ecosystem – the devices and network infrastructure -- remains secure?

Smart City device security begins at the component level 

Smart City device manufacturers -- from smart lighting and water systems to smart traffic management systems and transportation systems -- serve as the first line of defense when it comes to security. Each device may feature many technologies working together such as chipsets, sensors, communications protocols, firmware and software. These technology components must be built or sourced with security in mind. 

Security testing of components and devices should not be an afterthought, but a proactive part of the design and manufacturing process. Best practices may include:

• Communication protocol testing - For example, Bluetooth vulnerabilities like Sweyntooth and Braktooth in communication chipsets, could open the door to hackers. Braktooth vulnerabilities recently impacted billions of devices from the system-on-a-chip (SOC) in more than a thousand chipsets used in laptops, smartphones, IoT and industrial devices. Protocol level vulnerabilities like these are difficult to detect. While the security community established best practices for discovering application-level vulnerabilities, protocol-level vulnerabilities are much harder to pinpoint. The only way to test for these kind of vulnerabilities is using protocol fuzzing which detects vulnerabilities during the communications handshake or hand-off process. 

• Cybersecurity firmware, software and password update capabilities - Cybersecurity threats and vulnerabilities change over time. Many headline-making IoT security incidents have been caused by poor passwords and out-of-date firmware. Device manufacturers can take simple steps to enable Smart City device owners to strengthen authentication and provide methods to update firmware and software as the cybersecurity landscape evolves over the lifetime of their devices. 

Unfortunately, once a device is purchased, there is little a Smart City can do to Boost its security, so making the right purchase is the key to success. The purchasing process should consider cybersecurity in the “bill of materials” (BOM) that requires that the device manufacturer considered component and device cybersecurity and can validate that their devices passed appropriate cybersecurity testing. Smart City owners should keep in mind that over time, smart device manufacturers may continue to develop new devices with short product cycles. This means that owners will need to understand that manufacturers will may accelerate dropping support for older devices.

Taking the risk out of the Smart City network

The second line of defense in a Smart City is network infrastructure. In a Smart City, the back-end network is the nerve center that keeps everything running smoothly. That’s why it’s important for Smart Cities to rigorously test their back-end network’s security posture including policies and configurations on a continuous basis.

There is additional network infrastructure to consider. Smart Cities now connect operational technology (OT) systems such as water and energy utilities to Smart City network infrastructure. These OT connections increase the risk to the network since they are prime targets for bad actors. OT systems traditionally existed as stand-alone city infrastructure separated from the connected network. Now, newly connected to the shared network infrastructure, OT systems must be secured like traditional IT systems. 

Smart City owners should follow cybersecurity best practices to Boost their overall network security posture. Smart City network infrastructure demands a proactive approach to find vulnerabilities before hackers find them.  A proactive approach includes utilizing breach and attack simulation tools to continuously probe for potential vulnerabilities. Adopting these tools can:

• Prevent attackers from moving laterally across the network

• Avoid “configuration drift” where system updates and tool patches cause unintended misconfiguration and leave the door open to attackers

• Reduce dwell time by training your security information and event management system to recognize indicators-of-compromise for emergency or common attacks.

Smart Cities promise to deliver value from big data and analytics. However, for every new connection, there’s an attacker looking to exploit it. For Smart Cities to truly live up to their promise, we shouldn’t forget that – like all infrastructure – safety and security are a top priority.

Killexams : First-Time Exhibitors


First-Time Exhibitors

This year, 1500 companies will be exhibiting at the 2006 MD&M East show, significantly expanding its major pavilions. In the following pages, MPMN talks to several newcomers to the show and finds out their reasons for making their inaugural appearances.

Machine Manufacturer Bears Down on MD&M

Shana Leonard

Quality is a concept that Rollomatic Inc. (North Sutton, NH) takes seriously. Like most businesses, the company performs extensive quality control testing on its machines to ensure the highest standards. However, the grinding-machine manufacturer goes beyond testing protocols. The firm asserts that, in addition to testing at each stage of development, a typical Rollomatic unit undergoes 72 hours of grinding movement simulation and endurance tests. On top of that, machines run preprogrammed tasks to monitor operational tolerances and performance parameters whenever the product is not being directly worked on.

It is this dedication to quality that impels the company to seek it in everything it is connected with, including trade shows. Citing the event’s large audience, proximity, and influence in the medical industry, Rollomatic will exhibit at MD&M East for the first time in order to show off its quality-marked machines.

Despite its genesis as a producer of tools for the watchmaking industry in 1950s Switzerland, the firm’s focus now lies in the manufacture of precision tool-grinding machines. The machines are configured for a variety of applications that include deburring and metal cutting. Suited for creating surgical tools, the grinding machines have played a role in the production of bone saws, scalpels, rasps, and tweezers.

This influx of medical uses for its machines had a hand in Rollomatic’s decision to make its MD&M East debut. Though representatives had attended numerous MD&M shows over the years, the company chose not to exhibit because its primary source of business was not the medical industry. But the firm is looking to change that, opting to delve more deeply into medical applications for its machines. And it will start this mission close to home.

“We recognize that there is a significant amount of medical companies grinding on the East Coast,” says Rollomatic marketing manager Christina McKahan. “These are the companies we would like to reach out to.”

Another motivation to exhibit at MD&M East proved to be the release of the latest iteration of one product and the addition of enhanced features to another. Rollomatic will showcase its new loader, capable of grinding tools up to 16 in. in length. The unit can autoload tools or manually load ones measuring up to 24 in. in length.

Meanwhile, the firm’s 620-series automated six-axis CNC precision grinding center now features a clamping system designed to accommodate flat or irregularly shaped tools. It also boasts a horizontal magazine-loading system for the loading of tools up to 16 in. in length.

“It can even run in a lights-out environment with little-to-no deviation in part quality,” McKahan says. “Companies will find very little difference, if any, from the time they leave to when they check the precision upon returning.”

In addition to showing off its most latest machines, Rollomatic also plans on nurturing relationships with its existing customers. As McKahan points out, a large portion of the company’s business is repeat business. And, of course, it couldn’t hurt to talk up the firm’s quality-driven processes.

“We hope to create a positive presence and to learn more about the medical industry, as well as to present Rollomatic grinding machine capabilities,” McKahan says.

It’s Déjà Vu All Over Again with Injectech

Corinne Litchfield

It’s no accident that the staff of Injectech LLC (Loveland, CO) seems familiar to MD&M attendees. The injection molding firm was founded six years ago by former employees of a large barbed-fitting manufacturer. By drawing from its employees’ collective expertise, the company has developed its own line of barbed luers. “We started off as a custom molding and contract assembly house,” says company representative Dave Splett, “but we wanted to offer products as well.”

Injectech will display its new line of barbed luers at the show. The luers are available in materials such as nylon, polypropylene, polycarbonate, radiation-stable polycarbonate, and styrene. The company has also developed PVC barbed luers as an alternative to traditional polycarbonate. “The PVC does not stress crack when it’s bonded,” explains Splett. The company will also be showcasing its antimicrobial tube connectors, injection sites, barbed tube-to-tube connectors, and blood pressure monitor components.This year’s MD&M East show is a chance for the company’s personnel to reconnect with the medical device industry. “We’ve worked with a lot of medical OEMs over the years, so we’d like to reintroduce ourselves as Injectech,” says Splett.

Contract Firm Was Established to Serve Medical Market

Shana Leonard

Before deciding to exhibit at MD&M East, National Qualpec (Lancaster, PA) solicited input from its peers about the show. Companies described exhibiting at MD&M East as a rite of passage. They claimed that it serves as a necessary step in legitimizing a business in the medical field, according to the firm’s market development coordinator Mark Bos. Heeding its colleagues’ advice, National Qualpec will be initiated into the medical manufacturing industry this year at MD&M East.

The opportunity to establish credentials in the industry couldn’t come at a better time. Only several months old, National Qualpec is trying to make a name in the medical market. Though still in its formative stage, the contract manufacturer has a lot of guidance and experience to fall back on. National Qualpec is the medical-oriented offspring of National Bearings Co., which has been manufacturing bearings for 89 years.

“Manufacturing requires that you have a really hurry understanding of how components are integrated with one another, because if you don’t get all of the components right in a bearing, the result can be disastrous,” Bos says. “Our skill at creating components that fit well in assemblies, whether metal or plastic, is key.”

National Qualpec was conceived following an analysis of the medical market. Competing fiercely with aggressive Chinese manufacturing, National Bearings sought a field that was both growing and active in the United States. The seamless application of its skill sets to medical manufacturing sealed the deal.

“The crux of our research was that the things that we’re good at manufacturing are things that there is a need for in the medical industry, and the strong growth in that industry is very attractive to us,” Bos says.

Established exclusively for the manufacture of precision-engineered medical components, the firm specializes in metal stampings, as well as injection- and insert-molded products. The company maintains that addressing a universal need works to its advantage. As Bos points out, manufactured components are in demand and can be leveraged to meet different application needs.

These manufacturing capabilities are what National Qualpec will be showcasing at MD&M East. In its inaugural year as an exhibitor, the company hopes to be accepted into the medical manufacturing society, as well as to get a foot in the door.

“Our biggest expectation is to get a chance to meet device manufacturers and get a better sense of the things that we can offer them,” Bos says. “We just want to meet them and show them where our skill sets are and how we can help them meet their component manufacturing needs.”

Component Manufacturer Seeks Connections at MD&M

Shana Leonard

Despite being grounded in the medical industry, L-com Connectivity Products (North Andover, MA) is pursuing a slew of new business prospects stemming from the rise of high-tech equipment in the field. In light of the tidal wave of technology flooding the medical arena, L-com has decided to dive right in by becoming a first-time exhibitor at MD&M East.

“The advent of diagnostic equipment that utilizes video, audio, and data transmission requires device designers to take advantage of numerous connectivity solutions, which L-com specializes in,” says Carol Williams, the firm’s national accounts manager.

While many first-time exhibitors at MD&M East are latest converts to the medical market, L-com is a veteran. The manufacturer has been supplying the medical industry with connectivity products for more than 20 years. L-com manufactures copper and fiber cable assemblies, wire harnesses, connectors, adapters, and rack panels. The company provides custom engineering and manufacturing services as well.

“L-com carries all the components required to manufacture the cables, as well as the finished cable assemblies,” Williams says. “Due to our years of connectivity experience, we offer the latest in interface technology as well as niche products that provide solutions to common interconnect challenges.”

Medical uses of the business’s products center around scanning and diagnostic equipment. Its connectors have been used in field-deployable MRI and oncology equipment by such clients as Siemens Medical and Varian, according to Williams.

While at MD&M, L-com will display a number of its products. Among them will be hospital-grade cord sets and high-definition multimedia interface cables for audio and video equipment, as well as enhanced video and shielded Category 5E–certified patch cables.

“We hope to gain exposure to the latest designs and technologies in the medical equipment industry,” says Williams. “This will deliver L-com exposure to connectivity challenges that the medical industry is currently faced with, as well as the chance to display our full product offerings and capabilities to the attendees.”

Dispensing Product Company Aims to Make an Impression

Shana Leonard

Established in 1992, PVA (Halfmoon, NY) hails from humble beginnings. Built from the ground up, the company was born when founder Anthony Hynes began selling dispensing valves out of his home. From a residential dwelling to Rensselaer Polytechnic Institute’s Incubator Center to a 20,000-sq ft facility, this dispensing system company seems to thrive regardless of its element. This year, the firm will pack up its wares once more—albeit temporarily—for its debut at MD&M East.

Since its domestic days, PVA has amassed a sizable catalog of dispensing products. Among its offerings are a range of automated and manual adhesive-dispensing and selective-spray-coating equipment. Products include application equipment such as valves, pumps, and needle tips. Manual dispensing systems such as dispense valves, controllers, and syringes are manufactured as well.

Until recently, PVA had primarily serviced the automotive, electronics, and home appliance industries. However, the small company has witnessed the growth of the medical market over the past few years and has envisioned a role in its continued success.

Despite being new to the medical industry, the company staff is confident of its abilities. According to them, they can’t afford not to be. “We’re trying to take advantage of being the new kids on the block in this market, and having technological advantages helps,” says Frank Hart, director of marketing and regional sales for PVA. “This is our specialty; all we do is dispensing,” he adds. “We don’t have something else to fall back on; we need to do this right the first time.”

MD&M East represents the business’s pioneering venture into medical trade shows. The company credits the convenient location and regional crowd as its motivation to exhibit. Furthermore, PVA wants to demonstrate the flexibility of its products and their uses in the medical market. Among them are dispensing tools for circuit boards and devices that require coating in order to protect a source or housing from the environment.

While at MD&M, the company hopes to generate interest in its latest product, the PVA650. The unit is a three- or four-axis x-y-z robot that uses programmable motion to apply conformal coatings, RTV, surface-mount adhesives, and two-component compounds.

In addition, the company will promote its capabilities in the automation of conformal-coating, potting, and adhesive applications with its multiaxis positioning systems. Selective conformal-coating systems use controlled spray application with a transfer efficiency of up to 99%, according to the firm.

And while promoting its products is a definite priority, the company is eager to just get acquainted with the industry and its players. “We would certainly like to develop some sales,” Hart says. “But the endgame would just be to get PVA out there and introduce ourselves as a flexible solution, really just to open some doors to some contacts and conversations that we have not been privy to before.”

Software Company Renders Itself Useful to Manufacturers

Shana Leonard

Like the medical industry that it serves, Delcam International (Windsor, ON, Canada) specializes in breathing life into its subjects.

Through its software, the company equips users with the ability to create realistic CAD models and CAM programs for product development. Bridging the gap between concept and reality is the primary capability Delcam plans to spotlight while making its debut at MD&M East.

No stranger to trade shows, the company has exhibited at machine tool shows such as WESTEC, EASTEC, and IMTS. However, MD&M East marks Delcam’s first year targeting the medical industry as a vertical market, according to Delcam marketing manager Mary Shaw. “It is a healthy and growing industry that has been turning to CAD/CAM solutions to Boost product quality, manufacturing efficiency, and repeatability,” she says.

Heralding its status as the only international CAD/CAM software supplier with its own toolroom, Delcam provides a range of manufacturing and inspection products suited for medical manufacturing. The software enables the viewing of awkward angles, application of textures, and development of complex 3-D models. Furthermore, users can combine scanned data with CAD to design, engineer, and manufacture implants and prosthetics, according to the company.

Among the products Delcam plans to exhibit at the show are its PowerMill 6.5, PowerShape 7.0, and CopyCAD 7.0. These programs enable computer-aided design and modeling, computer-aided manufacture of complex tooling and machining shapes, and reverse engineering, respectively.

Also on the MD&M agenda is the promotion of Delcam’s custom software group. The group serves to help customers automate repetitive processes by applying the firm’s software to design, manufacture, and inspection procedures. Custom software is also available.

“We are looking forward to educating designers and producers of medical components about the CAD/CAM solutions we have to offer that can shorten the time from design to production,” Shaw says.

Machining Firm Saddles Up for New Challenges

Corinne Litchfield

It’s been 50 years since Cox Manufacturing Company, Inc. (Comaco; San Antonio, TX) opened for business, and yet MD&M East marks one of the first times the company has exhibited at a trade show.

Admittedly, the CNC turning and machining services firm doesn’t see much local business. “Traditionally, there hasn’t been much medical manufacturing in this area of the country,” says Bill Cox, CEO. The company’s customer base is widespread, with about 20% of its business coming from the Northeast.

Comaco has been working with medical manufacturers for more than 30 years. “The medical industry has so many intricate designs,” says Cox. As a result, the firm has produced medical components such as spinal implants, bone screws, and in vivo flow tubes for artificial heart pumps. The company has also built parts used in laparoscopic instruments and other surgical equipment.

In addition to its CNC Swiss lathes and multispindle screw machines, Comaco has 12-axis CNC Swiss machines and a full-access toolroom. “We offer different types of machines for different quality thresholds,” says Cox. The company can also develop tooling in-house for specific applications. Materials used include titanium, stainless steel, brass, aluminum, and metal alloys.

Engineers and buyers who are looking for precision machining of complex parts are more than welcome to visit Comaco’s booth. “We have always sought more-challenging work, and medical manufacturing offers us new challenges,” says Cox.

Electronics Firm Enters the Medical Trade Show Circuit

Shana Leonard

Tim Knox, president of Telco Solutions III (TS III; Franklin, TN), believes that his company exhibits a difference you can see. That is, anyone that visits the electronics manufacturer’s facility can see. “We would more than welcome people to come in and see our facility,” says Knox. “When they do, we’re almost 100% successful in convincing them to become a customer.”

Convincing companies to tour its facility to witness the firm in action is just one objective for Knox and TS III as they travel to New York to exhibit for the first time at MD&M East. Other goals for the show include forming contacts and getting the word out about TS III’s medical manufacturing capabilities.

An electronics jack-of-all-trades, the contract manufacturer offers PCB, wire harness and cable, and electromechanical manufacture and assembly. The firm consists of four divisions focusing on PCB manufacturing, cable and wire manufacturing, Nortel telecom distribution and remanufacturing, and semiconductor testing.

Because the low-volume, high-mix aspect of the medical marketplace melds so well with the firm’s business model, it is looking to increase its presence in the field. In addition, expanded capacity, increased technical knowledge, and an in-house sales force have motivated TS III to more actively target the medical industry. The possible acquisition of a medical-oriented company has also contributed to the pursuit of medical business.

The company has produced PCBs for a number of blood analyzers, and is adept at manufacturing safety-critical elements, where repeatability and reliability are necessary, according to Knox. From lead-free products to BGA capabilities, the company maintains that it offers products for tomorrow. However, today isn’t neglected, Knox claims. The firm provides lead-based products when requested, as well as SMT and PTH technology for those not working with BGA.

In addition to forecasting the future of its markets, TS III also analyzes virtually everything it is associated with in order to avoid jeopardizing the credibility of the business. Even trade shows such as MD&M East are carefully evaluated. But according to Knox, the event passed the test.

“The show has a good reputation and we watch where we participate and with whom our company is associated from a reputation standpoint; it came well recommended,” Knox says. “So we thought it would be prudent for our company to be present as well.”

Company Tests Out MD&M East

Corinne Litchfield

While Laboratory Testing Inc. (LTI; Hatfield, PA) may be new to MD&M East, the testing and calibration company is not new to medical manufacturers. In fact, many of its customers make medical instruments and implants, and that number seems to be growing. “Medical is a big part of our customer base,” says marketing manager Sharon Bentzley. “We can provide the testing and calibration services to support their quality requirements.”

The firm specializes in metal and alloy testing, specimen machining, and failure analysis and calibration services. Metals found in fasteners, tubular products, bars, plates, and castings can be tested. Several types of nondestructive testing are also available.

The company’s metrology division provides dimensional, pressure, force, torque, mass, and vacuum calibrations. Field calibration service is offered for surface plates, hardness testers, optical comparators, balances, hand tools, and testing machines. LTI uses CNC machines to prepare specimens for testing mechanical equipment.

All testing and calibration results are fully documented. “Our materials engineers provide summaries of all findings,” says Bentzley. “The summaries include information on what caused a failure and how to prevent similar events in the future.”

LTI is a regular exhibitor at design, welding, and machining trade shows. This is the first time the company will exhibit at a trade show specifically for medical manufacturers. “MD&M East is convenient to our office, and we expect it will deliver us an opportunity to increase the industry’s awareness of our services,” says Bentzley.

Killexams : Vent panels contain fire

Belleville, Ontario -Marc Soubliere wants to protect his customer's investment. As a Nortel design engineer, he needs to be sure that if any fires were to originate from the company's rack-mounted equipment, adjacent equipment would not be burned. He's also concerned with EMI shielding.

Soubliere could have used many types of EMI shielding products, but he chose StreamShield, a shielding air vent panel with fire-retardant coating from Parker Hannifin's Chomerics Div. (Woburn, MA). "The characteristic that interests us is the flame control this panel offers," says Soubliere.

StreamShield has a thin layer of intumescent coating in the vent's honeycomb cells. When exposed to flames or heat above 300F, the coating expands rapidly, filling the cells with carbonaceous foam that prevents flames from propagating through the honeycomb.

"We conducted a number of worst-case qualifying tests where the performance of the fire retardant HEICF 1594 intumescent coating system offered an extremely impressive flame containment performance," says Soubliere. The HEICF 1594 coating helps enclosures meet the requirements of network equipment building systems and Bellcore GR-63-CORE physical protection standards for fire resistance.

StreamShield EMI vents provide more than 50 dB shielding effectiveness from 1 to 10 GHz. Open area of the honeycomb is 85% with the intumescent coating.

Killexams : Market Focus: Workhorse products

One of the product categories that can be considered to make up the industrial market is those infrastructure products that support the booming electronic and telecommunications industry. This year's SPI Structural Plastics Conference and Design Competition focused on some of these interesting applications.

An eye-catching example from the industrial telecommunications perspective was the award-winning Alcoa Fujikura splice box, molded and submitted by Mack Molding (see opposite page). The part represents a metal-replacement trend in this market that's been under way for several years and is now reaching critical mass.

Unless you've been in a coma for the last five years, you know that the digital revolution is well underway. Baby Bells, AT&T, MCI Worldcom, Sprint, British Telecom, and a host of other mega-companies are positioning themselves to build and cash in on new and improved telephone, cable, and mobile communications networks. These networks have an infrastructure being built by the likes of Lucent, Nortel, and Motorola.

Joel Fouquart, technical manager at GE Plastics, says the Alcoa/Mack splice box is the best example of the trend occurring in the outdoor infrastructure arena. The Alcoa box replaces a diecast aluminum predecessor that weighed 65 lb and was a beast to install. But with a switch to GE's Valox PBT and structural foam molding, Alcoa suddenly had a lighter, equally durable, less expensive box that could be produced in volumes. That, says Fouquart, is the key-producing in high volumes to accommodate the new and improved networks under construction.

Indoors, Fouquart says the central office is the scene of the most changes. Not happy producing simple computer and electronics cabinets and housings, many manufacturers are looking to plastics and injection molding to create a more striking identity, similar to the job Silicon Graphics has done with its standout colors and contours. Fouquart says many OEMs struggle to determine the break-even point between plastic and metal.

The economic advantages of plastics increase with part complexity. Plastics allow designers to incorporate unique features that are often difficult to impossible to produce in sheet metal. GE and Fouquart conducted a study using a standard 6-ft cabinet panel with moderate contours and complexity, and compared the cost of producing it via structural foam vs. metal. The sheet metal, he says, has an initial tooling cost ranging from $10,000 to $90,000, where an injection mold ranges from $100,000 to $275,000.

However, downstream welding and shaping of the metal ballooned the per part cost to $550 for metal compared to $350 for plastic. Not only that, but the break-even volume for the plastic part is 1000 units annually.

For Example
The Best Paper winner at the Structural Plastics Conference was written and presented by Michael Caropreso, who, with Hewlett-Packard, devised a system for molding plastic panels to replace a large metal door on a peripheral computer rack system. The metal door H-P was looking to replace cost $40 to make and $150 to ship because of its size, and was often damaged in transit.

The series of smaller plastic panels would prove less expensive to make, and ship, and easier to use for service personnel who need to access cabinets. But what made the project particularly interesting was the rare combination of gas-assist molding and sequential gating.

The panels are 35 inches long and 16 inches wide, with a nominal wall thickness of .140 inch, unpainted and with no visible sink marks or weld lines allowed. Two gates were used in the mold, both fed by a hot manifold system with hydraulic valves.

To establish production parameters, the mold was filled through one gate in a series of short shots that were used to determine the ram position at which the flow front reached the second gate. This position was used to trigger the second valve, which finished filling the part. This overlap in flow fronts rendered weld lines invisible.

Gas filling begins after both gates close. A series of carefully guided gas bubbles help pack out different sections of the panel, provide strength, and eliminate sinks. The entire cycle runs in just over a minute, with no secondary operations. The molder produces the parts at facilities in California and Dublin, Ireland.

Metal-to-plastic conversion takes the weigh off

Replacing its eight-part diecast aluminum predecessor, this structural foam molded splice box weighs less than half as much and greatly reduced the total part count. The splice box, manufactured for Alcoa Fujikura Ltd. by Mack Molding (Arlington, VT), is mounted on utility poles and buildings and is used to house and protect spliced fiber optic connections.

"An excellent metal replacement application, this splice box previously weighed 65 lb," says Brian Sumpter, new business development director at Mack's southern division. "We've reduced that to 29 lb, which is a tremendous relief to field service personnel who are hoisting these units up telephone poles to install them." The 10-by-30-inch box consists of two primary parts: one is a drawer in which lines are spliced; the other is the enclosure into which the drawer slides (see photo). The drawer accommodates up to 360 fiber splices and up to six individual cables of various types and sizes. The gasketed drawer can be easily opened for periodic maintenance.

Called the Opti-Guard splice box, it's high-pressure structural foam molded of Valox PBT from GE Plastics at Mack Molding's Inman, SC facility. The material was chosen to meet requirements of UV exposure, ballistic resistance, impact resistance of 100 ft-lb or more at -40F, and temperature resistance ranging from -40F to 176F. Also, Alcoa's internal tieoff system resists more than 100 lb of tension per cable.

The part was an award winner at the Structural Plastics '99 Conference and Design Competition, an annual event hosted by the Society of the Plastics Industry.

Rare-earth compound, plastic unite for speedometer part

All the plastic parts you see in this Bitorque speedometer, designed for some models of Harley Davidson motorcycles, are molded by Thomas G. Faria Corp. But the two parts below the speedometer required a special material. Called bobbins, the parts hold a pin that connects to a magnetic source on the back side of the speedometer. That magnetic source emits a varying electrical charge based on how fast the engine is running. The bobbin, connected to the pin and a meter, rotates according to that charge, thus telling the driver the vehicle's speed.

Faria needed a moldable, highly filled, high-temperature polymer that could be insert molded and then magnetized as part of the inner electrical workings of the speedometer. It hired custom compounder Foster Corp. (Dayville, CT), which developed a compound from a nylon and a rare-earth material called ferrite (an iron-based material). Specifics of the material were not released, but according to the molder, the plastic version is equal in quality to the chrome-plated, hand-finished instrument made for other Harley motorcycles.

Faria runs 40 or so injection molding machines ranging from 15 to 200 tons at its Uncasville, CT plant.

Regenerative pump housing benefits from PPS

Designed to house regenerative pumps for use in soft drink dispensing systems in the U.S. and the U.K., this part is required to withstand up to 30 bar of pressure and must operate in temperatures ranging from -4F to 212F. Chemical resistance is required to withstand periodic purging with cleaners. Good surface hardness and dimensional stability are also required. Chosen to mold the part: 40 percent glass-filled Fortron PPS from Ticona.

The critical component in the housing design is the back plate. Stress analysis conducted during the design phase indicated that unacceptably high stress levels in key areas around the connecting points could cause the part to fail. A new design was submitted in which the overall wall section was increased, ensuring greater strength and dimensional stability, with cored-out sections to minimize material use.

Tests on the new design showed a reduction in strain levels around the connecting points by a factor of three. Tests also predicted that the design would be able to meet the stress requirements as well as maintain the .05 mm flatness required for the pump's impeller. The housings are made in the U.K. by Electromag-Neil, which insert molds the stainless steel threads for connecting pipes.

Polypropylene wheel unit endures heavy weight

This four-caster wheel unit, called the Universal Gondola Skate, is designed to facilitate safe and easy movement of heavy, fully loaded shelves during renovation of retail stores. The wheels are placed under the shelves so that during a store's off hours, the shelves can be moved out of the way to make room for renovation and construction. Then, they can be easily rolled back to their place during regular store hours. They are designed to hold up to 2000 lb and reportedly cost up to 50 percent less than comparable products.

The idea was co-developed by Cozza Harris Design (San Diego) and Co-Mack Technology (Vista, CA). Co-Mack molds the part in a structural foam molding process on a 385-ton Battenfeld. Up to 700 wheel units can be produced in a day on the single-cavity mold. The part is made from a 10 percent glass-filled polypropylene from RheTech Inc. that doesn't have to meet tight tolerances, but must offer strength. The casters are purchased out of house and assembled at Co-Mack.

Tension knob gets lubed with switch to acetal

The knob on the Ovation 2 thermal transfer printer is used to adjust ribbon tension each time a different width label is used. The printer produces labels up to 4 inches wide and is used to make bar codes, tags, and other products. The tension knob is used intermittently, but not continuously. For Orlando-based manufacturer Datamax, this was a problem with the material used previously, which tended to bind up if the knob was not frequently used.

"The binding," says Ken Colonel, director of mechanical engineering at Datamax, "was due to the fact that the knob is a part that is not in constant operation. The lubricated material we previously used would have worked fine had this been the case. Frequent use would have brought the internal lubricants to the surface and allowed for better performance."

For help, Datamax switched to Fulton 441D, a silicone lubricated acetal composite produced by LNP Engineering Plastics. Because of the silicone's limited compatibility with the base acetal material, it migrates to the surface of the tension adjustment knob. The result is a continuous generation of silicone film, which serves as a boundary or lubricant.

Encapsulated solenoids endure with PET

Solenoids manufactured by Caterpillar Inc. are designed to operate hydraulic valves on heavy-duty equipment used in construction, mining, and agriculture. The key to the solenoid's durability is the encapsulation, which blocks moisture and insulates the unit from sudden temperature changes.

Previously overmolded with a thermoset or other thermoplastic, the solenoid is now encapsulated with 30 percent glass-filled Rynite PET from DuPont. More durable than previous designs, the encapsulated product meets Caterpillar's standards for resistance to heat, thermal shock, vibration, moisture penetration, fuel, and lubricants. The company rates solenoids for service at ambient temperatures from -40F to 250F. The PET is also used to mold a coil bobbin that is part of the assembly.

John Hoffman, an engineer for Caterpillar, says the new design and the switch to Rynite PET makes the new units less expensive to produce than the ones they replace. Also, the addition of an integrated electrical receptacle into the encapsulation shell saves the cost of an additional part. The solenoids are installed on bulldozers, wheel loaders, motor graders, agricultural tractors, and off-highway mining trucks.

TPE rubber used in electrica plugs, connectors

Electrical products maker Leviton Mfg. in Little Neck, NY makes this watertight locking plug and connector assembly for indoor and outdoor industrial electrical applications. Called the Wetguard, the unit is used to connect two flexible cords in order to supply power to electrical appliances, tools, and machines in a safe and simple installation procedure. The guard shields the connection from threatening environmental elements, providing protection from moisture and dust.

Leviton molds the Wetguard with a Capron nylon 6 from AlliedSignal Plastics and overmolds it with a Santoprene thermoplastic elastomer from Advanced Elastomer Systems. Santoprene not only gives a tactile feel, it also provides resistance to harsh environments, insulation, and good part uniformity and sealability. Levitron specified nylon-bondable grades of Santoprene because they chemically bond well with Capron, thus eliminating any possibility for leakage in the area where the two parts meet. The combination also reportedly resists crushing, impact, and abrasion.

The plugs and connectors, which are available in 15A, 20A, and 30A Nema ratings, feature a tongue-and-groove design, meaning when the male and female parts of the plug and connector are put together, it seals itself. It also has a locking indicator that gives the user visual confirmation that a seal has been obtained.

The Wetguard enclosure consists of two parts that are insert injection molded on a 150-ton press in a two-cavity mold. Previously, enclosures for the 15A devices were designed as a two-part assembly, which, according to Leviton, was a slow operation that often provided an unsatisfactory seal.

Multimeter features one-shot overmolding of TPU resin

Tektronix Inc. wanted to Boost the durability of its TX-DMM family of true RMS digital multimeters, and ease the manufacturing process at the same time. Handheld DMMs are the most common of all electrical and electronic test instruments. Tektronix used film insert molding to Boost the bezel and display window of the DMM but the back cover presented some design molding challenges.

The back cover, which is injection molded with Bayer's Bayblend FR110 PC/ABS resin, requires three additional parts molded with an elastomer resin: a water-resistant gasket that seals the DMM's electronics from moisture, dust and other elements; a mechanical connection that holds a metal electromagnetic interference shield inside the back cover; and four no-skid pads on the outside of the back cover. Poly-Cast (Tigard, OR), which molds the front and back covers, wanted the three parts to be molded from the same material in just one shot. It chose Bayer's Desmopan KU2-8651 TPU resin, with a 75 Shore A hardness, because it offers good flexibility, resilience, and compression-set properties.

After the Bayblend PC/ABS back covers are molded, Poly-Cast inserts them and an EMI shield into the press. The Desmopan resin is shot onto the back cover through two gates. The resin flows around the lip of the back cover to form a watertight gasket. It then continues through an opening on each side of the part's interior and flows into separate lines over the EMI shield. Finally, the resin flows through openings in the EMI shield and back cover to form four capsule-shaped feet on the outside diameter of the DMM's back cover.

According to Steve Lyford, mechanical engineer for Tektronix, it was less expensive to overmold the parts using this process than to perform a secondary operation by hand. Tektronix had previously used a custom-made gasket, but preferred the overmolding operation even though the mold was tougher to build because the resin has to run a long flow path. The complex mold was built by Bestco of Hillsboro, OR.

Killexams : Virtutech Announces Simics Full-System Checkpointing for SystemC Based Transaction-Level Modeling Virtualized Systems Development Platform Provides Full Support for Multiple Modeling Languages

SAN JOSE, Calif. -- Jul 27, 2009 --  Virtutech®, Inc., the leader in virtualized systems development (VSD), today announced that Virtutech’s Simics® platform now provides full-system checkpointing for SystemC™ based transaction-level modeling (TLM). OEM and semiconductor developers now can save, restore and share the precise and full-system state to bypass lengthy system boot and restart steps, share the system among engineering team members, capture and duplicate bugs, parallelize testing and offer product training from virtual platforms.

Virtutech is the only vendor to enable full-system, mixed-architecture checkpointing that reaches far beyond a simple save and restore function for individual elements of a SystemC virtual platform. The Simics checkpoint captures a snapshot of the complete system and can be restored at any point or location, on any host and by anyone so that software development, integration or test efforts can continue as if they had never been interrupted. Simics checkpointing works with mixed modeling languages to enable unique capabilities such as language freedom, portability across model versions, differential saving of memory and disks, the ability to easily change the level of model abstraction and to archive multiple target setup configurations.

“As SystemC transitions towards becoming a more supported design language for ESL, full- system checkpointing for SystemC is one of the features that customers are beginning to expect and request from tool vendors,” said Mark Burton, managing director of GreenSocs Ltd. “Naturally, we are excited that Virtutech has now provided this capability within Simics. The use of checkpointing will increase model accuracy, development team productivity, and it is a feature that is critical to broadened adoption and use cases for SystemC models.”

In the past decade, checkpointing has become one of the most utilized and valuable capabilities within Virtutech Simics. The addition of SystemC checkpointing complements existing support for models written in C, C++ and Python to provide developers with a seamless, robust simulation solution for software, hardware and systems development bringing benefits that are difficult or impossible to achieve using physical hardware.

“We find that our customers are deploying increasingly complex mixed-architecture systems in combination with a variety of processors including CPUs, DSPs, ASICs and FPGAs,” said Michel Genard, vice president of marketing for Virtutech, Inc. “One of Virtutech’s competitive advantages is the ability for Simics to combine individual, checkpointable component models written in multiple languages within a full-system virtual platform.”

For further information, Virtutech executives will be available at the DAC conference taking place at the Moscone Center in San Francisco from Sunday, July 26 through Friday, July 31, 2009. Jakob Engblom, technical marketing manager, and Ross Dickson, principal technology specialist, both from Virtutech, will be discussing a jointly authored paper in the session, “Design Flow for Embedded System Device Driver Development and Verification,” on Tuesday, July 28, from 4:30 p.m. – 6:00 p.m., in room 132. Engblom will also be participating in the panel, “The Wild West: Conquest of Complex Hardware-Dependent Software Design,” on Thursday, July 30 in room 131.

About Simics

Simics is a high performance full-system simulator that enables engineers to develop, debug, test and run their entire software application stack on a virtual representation of their target hardware or virtual platform. The overall engineering development efforts are reduced through advanced capabilities normally not available with physical hardware: non-invasive debugging and tracing, saving and later resuming execution, full deterministic behavior, built-in networking capabilities, forward and reverse execution, ability to examine, control, and break on any internal device and to inject faults, and the ability to save system state and later replay it.
