Killexams : Post-pandemic printer pains
Shaun Hattingh, Datacentrix.

Shaun Hattingh, Datacentrix.

The pandemic had a massive impact on the printing business and on the business of printing. Millions of suddenly remote workers experienced a seismic shift from traditional print-based processes to digital ways of working, with printers losing significant commercial ground. IDC revealed that print volumes had dropped by nearly 14% in 2020, with the likelihood of this decline continuing as more companies adopt hybrid and remote working practices alongside paperless initiatives. Statista’s research reflects a somewhat similar trend with an uptick in printer sales in 2021 and 2022 followed by a dip in 2025.

These sentiments are shared by Forrester which, in its US Tech Market Outlook by Category for 2021 and 2022, found that the spend on peripherals will continue its slow growth in 2022 after a spike in 2020 and 2021 as companies invested into home office technology to keep employees and businesses going during the pandemic. Now, as the new normal blends both work and office, many companies are wondering if printers are perhaps as necessary an evil as they previously thought. Are the costs on ink, paper and device maintenance really worth it when digital can pretty much do everything, only faster?

According to a study undertaken by Konica Minolta and BPO Media, around 75% of respondents across consumers and businesses felt that a printer was somewhat important. This sentiment was echoed in another study by the Imaging Channel, which found 31% of people were copying and printing more than in the past. The printer isn’t dead; just like the PC, it’s simply going through a phase. What is interesting, however, is that even with declining printer purchase volumes, companies are experiencing soaring printer costs. According to an Epson survey, this is because the majority of employees (70%) were buying the wrong types of printers, which resulted in the business carrying the cost. This has seen an increase in managed print services that are now evolving to meet changing workplace and workforce expectations.

In South Africa, there also remains a cultural and administrative reliance on paper. Here, printing isn’t so much an obsolete practice as it is a mandatory part of life. In triplicate. Paperless is a distant reality for organisations looking to onboard suppliers and manage finance teams and ensure that systems are compliant. It is equally far in the future for financial institutions that rely on paper to ensure that RICA and FICA are obeyed. This is further complicated by the fact that a large percentage of the population is not digital or even close to becoming digitised, and this is not just a local concern. It’s a global one. According to the International Telecommunication Union, in 2021, around 37% of the world’s population had not used the internet. The correlation to the printer isn’t tenuous – it means that printers remain one of the lowest barriers to entry for a vast percentage of the population that’s seeking to engage with the organisation.

Printers and printing solutions are evolving to meet changing business and consumer expectations and will very likely loom dark and large in office corners for some time to come.

Printing trends in2022.

Brainstorm: What are some of thebiggest printer trends right now?

Caron de Fortier, manager, HP printers and supplies, Drive Control Corporation: Cloud-based managed print services have emerged as a major differentiator, with many organisations opting to partner with experts that manage their printer fleets remotely and offer benefits such as cost-per-page models.

Lee-Anne Letcher, product manager, CIG Marketing, Canon Southern Africa: Businesses can print their own flyers, posters, and point of sale because of the printers available to them. Another trend is to have printing devices that are efficient, with cost management features. Functions like skip blank pages, energy-saving capabilities, enforcing print principles (departmental printing), duplex scanning, fast first-time page, low energy modes and print preview before printing are all features that can make the businesses more efficient while bringing down their cost of printing.

Hilton McCall, head of Graphic Communications, Ricoh South Africa: There’s a growing need to manage more jobs with lower run lengths and better integration with digital communication and better workflow automation. These are designed to Improve printing operations while pursuing more efficient energy use. The shortage of skilled workers, particularly with inkjet experience, remains a challenge.

Shaun Hattingh, operations manager, Datacentrix: We’re still seeing a significant requirement for printing within the mining sector specifically; this arena continues to focus on hard copy documentation and more manual processing due to the nature of the environment within a mine. The medical industry also, to a point, still has a requirement for physical documentation.

Brainstorm: What kind of printing is dominating the business environment and how is this evolving?

Tamzin Gray, senior sales manager, Epson SA: According to the Printing Industry in South Africa 2021 report, the pandemic caused an increased demand for packaging due to the growth in online sales and greater demand for digital printing. In addition, there’s been an increased focus on sustainable printing in the business environment, due to hybrid and flexible working models. Energy usage is still a key challenge in the industry. Although 95% of organisations monitor their printer fleet’s energy consumption, only 35% have a clear view. There is, however, a strong desire in the business sector to understand more about the savings they could make by changing their print fleet management and by changing the types of printers in use.

Hilton McCall, Ricoh South Africa: The pandemic and worldwide lockdowns negatively impacted many printed application volumes. But sales of physical books remained strong and even increased across Europe and several other regions in 2021. Book printing remains a powerful business driver in the corporate market.

Nick East, sales director, Itec South Africa: Smart printing is dominating the business environment, resulting in savings on paper and other resources. Sensors in printers can send signals to indicate the need for machine maintenance or toner replacement, which is highly effective in reducing customer downtime. AI can also help reroute printing jobs automatically to another printer. Combining IoT with AI-enabled services can deliver more personalised solutions, predict paper usage, send alerts on possible breaches, and transform the printing environment into an efficient and highly reliable one.

Brainstorm: What technologies and solutions are shaping this market?

Lee-Anne Letcher, Canon Southern Africa: Digitalising documents makes the document more versatile and gives the business so many more options. It’s also no surprise the energy efficiency of the devices is top of mind, things like adaptable standby modes and timing, automatically turning the device off at certain times, like close of business.

Hilton McCall, Ricoh South Africa: There are many. These include: hybrid mail software, UV flatbeds, new scanner options for high-speed inkjet platforms, new workflow automations, and continued innovations for added colour stations, substrates, and others in direct-to-garment, latex large format, large format, wide format, and inkjet devices.

Mohammed Vachiat, head of Sales and Innovation, Konica Minolta South Africa: There’s a big move in favour of cloud computing, IoT, with the multi-functional device becoming commoditised in the process. Another shift is towards more robust security. In a secure environment, such as the printing of confidential or classified information, like exam papers, for example, the organisation’s ICT framework has to work hand-in-hand with the printer security features of the multifunctional devices in order to bring about complete peace of mind.

Clearing space for point of sale

How Cape Union Mart refined its payments and customer interactions by investing in printers that fit the space and the need.

Cape Union Mart, a one-stop destination for outdoor enthusiasts, travellers and explorers, is a well-known retailer with a solid outlet footprint across the country. The company required a mobile point of sale (POS) solution that was capable of working offline when there were power or network issues, and that could handle printing to very specific retailer expectations, speeds and standards. The company didn’t want customers to endure long queues and delays, particularly during power failures, while waiting to pay.

“Our mobile POS solution allowed us to introduce flexible instore payments that are faster and easier for our customers,” says Faizel Govender, IT Store Infrastructure and Systems Support coordinator at Cape Union Mart.“Then, because our customers still want physical receipts to ensure they can easily exchange or refund their merchandise, if necessary, we introduced the Epson TM-m3011 range of printers to the POS system.”

Printing isn’t so much an obsolete practice as it is a mandatory part of life. In triplicate.

The company opted for the printer range because they were small and compact and could use the same rolls of paper that were already instore. They added one to every store, giving customers the option to print the invoice if they didn’t want it emailed. In addition, the platform allows for the retail chain to use Bluetooth printing, which made it a lot easier for the team to manage POS printing across multiple mobile devices. “We opted to use the Epson series of printers because they work on most platforms and are easy to use and setup,” says Govender. “It’s a versatile printing platform and the setup process is genuinely easy to manage across different stores and devices. The company uses the TM-T70 series instore on the FEC POS terminals and the TM-m3011 printers on the mobile devices with the goal of using them on the new FEC devices that are to be introduced in the future.”

Improved store aesthetics

The company has been with Epson for a while as the printers not only tick the boxes of ease of use and reliability, but also meet its need for speed. As Govender points out, customers don’t like waiting, so slow printers are a hard no for the stores.

“We want to eliminate long lines so having these devices installed across the stores has meant that we’ve sped up the process by more than 50% because they print at speeds of up to 250mm per second,” he adds. “Plus, the colour is an important factor. These printers are black so they can be hidden better for improved store aesthetics and provide a sleeker look and feel. We also like the idea of using the white Epson printers in its Poetry stores as the colours would work well in that environment. Finally, another bonus is that these printers are smaller than older designs, so they free up real estate at the POS station.”

The printer range is compact and cube-shaped, so it allows for the retail firm to free up valuable counter space while fitting in with the aesthetics. The printers also come with a paper-saving function and near-end sensor so that employees can rapidly change the paper without impacting on queue times or efficiencies. The other advantage for the Cape Union Mart stores is that the connection with the mobile POS devices means that customers could retain social distancing regulations during the pandemic, and now are not constrained to stand in the check-out point queues.

“The printer range proved to be the perfect fit for our stores, and we’ve saved on maintenance and replacement costs because the devices are hardly ever faulty; they just keep working,” says Govender. “In the next couple of months, we will be rolling out the latest versions of the FEC devices to Improve efficiencies and we’re going to move the TM30s over to these devices instead of the TM70s so we can have faster results and constantly evolve our customer service and efficiencies.”

Killexams : Here’s How HP Recycles Its Ink Cartridges

With ambitious climate pledges, HP is tackling its sustainability goals tenfold.

One of the largest of these goals is to create full-scale circularity within the company. The current goal is 75% circularity by the year 2030, and HP's Chief Sustainability Officer, James McCall, is confident in their ability to achieve this.

Manufacturing 5.4 billion ink cartridges throughout 2021 alone, the company is focusing on these as they make up a large portion of their business. Each ink cartridge is already made of 50% recycled plastic, and at the HP ink cartridge recycling facility workers sort, disassemble, and shred reusable plastics to be made into new products.

Killexams : Why the Goodman Diagram Is Not So Good

One thing many mechanical engineers remember from their classroom days is the Goodman diagram. They may remember it as a tool for designing components for fatigue. If you ever took a class on machine design, you probably did homework problems using the Goodman diagram. If you're a professional engineer, you probably answered questions about it on your licensing exam. You may even use it in your day-to-day work. What you may not know is that it is misnamed, based on a conceptual misunderstanding, and often completely inaccurate.

In fatigue, stress goes back and forth between maximum and minimum values. The value halfway between the maximum stress and the minimum stress is called the mean stress (σm). The distance from the mean stress to the maximum or minimum stress is called the alternating stress (σa).

Fatigue testing is usually done with fully reversed loading, i.e., zero mean stress. On the basis of fatigue testing, an endurance limit is determined. The endurance limit (σe) is defined as the alternating stress at which the material will survive for a given (usually large) number of cycles without failure.

In real-life fatigue situations, the mean stress is often non-zero. For design purposes, it is desirable to be able to relate the actual mean stress and alternating stress in a component to the material's endurance limit. That's where the Goodman diagram comes in.

In the version of the Goodman diagram that is most widely taught, the vertical axis represents alternating stress, and the horizontal axis represents mean stress. A straight line is drawn between the material's endurance limit on the vertical axis, and the ultimate tensile strength (σu) on the horizontal axis. To use the diagram, simply plot the actual mean stress and alternating stress as a point on the graph. If the point lies below the line, the component will survive. If the point lies above the line, the component will fail.

Although this is often called the Goodman diagram, in honor of British engineer John Goodman, it is actually different from the diagram that Goodman published in 1899. It is more correctly attributed to another British engineer, B.P. Haigh, who published it in 1917. In Europe, it is called the Haigh diagram.

Regardless of what it's called or who came up with it, it's based on a fundamental error. To understand what the error is, remember what the diagram is supposed to represent: fatigue. Then ask yourself: What is the significance of values along the horizontal axis? Along the horizontal axis, the alternating stress is zero. If there is no alternating stress, how can there be fatigue? The assumption that the ultimate tensile strength is the limit of the fatigue strength as the alternating stress approaches zero may have made sense a century ago, when the nature of fatigue was not well understood. Today, we recognize that fatigue failure and tensile failure are two fundamentally different failure modes. There's no reason to believe that one is a limiting case of the other.

Most importantly, the Goodman diagram can be highly inaccurate. I recently did some fatigue testing on cast aluminum alloy 356-T6, and found that the Goodman diagram consistently over-predicted fatigue lives by a factor of three to four. For example, if the specimen was predicted to survive 1,000,000 cycles based on the equivalent stress determined from the Goodman diagram, it actually failed somewhere between 250,000 and 300,000 cycles.

Killexams : Hacking Electronic Price Tags

Something new is coming to a store near you: electronic price tags. [deadbird] decided to get one and see what makes it tick. First off it just looks like an LCD with some coin batteries and a simple board, but removing the batteries it was found that the text still appeared on the screen meaning its an E-Ink display.

Close examination of the chips on board shows that this model has an ATMEL ATMEGA16L, and a ATMEL952 25128AN (a 128k eprom with SPI interface), which makes this thing possible to bend to ones will. Also, dumping the eprom with an Arduino gets everyone a bit closer to decoding the instructions this thing needs to display its graphics, similar to the HP VFD hack we posted about not too long ago.

We have not seen these yet in our local shops, but supply it time and it is bound to start popping up in our favorite surplus locations soon enough.

Fri, 05 Aug 2022 06:00:00 -0500 text/html https://www.bizjournals.com/news/technology/startups Killexams : How lasers and lidar are changing the way wearables track health

“There is this battle going on between consumer wearables measuring your health and wanting to get more sophisticated, and the medical device companies trying to miniaturize and fight their way out of hospitals.”

This is how Dr. Andrew Rickman, CEO of Rockley Photonics, described the current state of the wearable industry in an interview with Digital Trends. The company is uniquely placed to not only understand how consumer and medical technology in wearables has started to converge, but also to help make it a reality with a unique, and incredibly accurate new health sensor technology.

Rockley, Bioptx, and Apple

It’s possible you’ve never heard of Rockley Photonics, but you’ve certainly heard of Apple — one of Rockley’s top customers. Rockley makes optical sensors and related components for consumer products and the healthcare industry, and most will be used in wearables. It’s therefore likely that existing Rockley technology is found in the Apple Watch’s health monitoring sensor array.

Dr Andrew Rickman, CEO of Rockley Photonics.
Dr. Andrew Rickman, CEO Rockley Photonics

In February this year, Rockley announced Bioptx, a platform designed to bring measurement of multiple biomarkers — including blood pressure, core body temperature, lactate, glucose, and a lot more — into a single sensor for non-invasive, continuous, and personal health tracking. Notably, Apple has also been linked to research into bringing non-invasive glucose monitoring and blood pressure monitoring to consumer wearables for some time.

But what makes the platform Rockley has developed so special, and why is it such a breakthrough? Rickman explained:

“The monitoring technology in the devices that exist today is very simple, and there’s little differentiation across consumer devices. Your heart rate is measured with a green LED, your blood is measured with a couple of other LEDs, and an ECG is an electrode on the back of the device. None of that technology is in any way advanced technology, and they are available to everybody.”

“What we are bringing is a powerful optical instrument, shrinking a $100,000 instrument down onto a chip, using a unique semiconductor process that’s not available to anyone else,” he continued, describing the company’s new technology. “That instrument collects incredibly rich data that we extract to measure, amongst other things, hydration, lactate, and blood pressure. That’s the breakthrough. Instead of a couple of LEDs and electrodes, what we’ve added is an instrument that measures multiple biomarkers with an unprecedented level of capability and accuracy.”

Lasers, not LEDs

Rockley’s instrument uses silicon photonics-based lasers to track biomarkers, not LEDs, and it’s a technology that hasn’t been used on a consumer wearable before. When you hear the word “lasers,” it’s tempting to think this means a shaft of red light beaming into your skin. But, of course, it’s not that. To explain, Rickman drew comparisons with lidar technology used on autonomous cars, the Apple iPad and iPhone, and for super secure face unlocking systems.

“It is a separate chip to the LEDs that you’d see in a regular wearable, and instead of electrical signals it uses optical signals,” Rickman said. “Our chip works using infrared and laser light at harmless power levels. The footprint on the back of a wearable is smaller than the space taken up by the LED array. It’s made using a silicon photonics process, and we needed to develop a completely new semiconductor manufacturing process, which is arguably the most sophisticated in the world, and unique to us. It has taken us nine years to develop.”

Why can’t a regular green or red LED system be used? After all, they’re a staple of existing health monitoring wearables.

“Those [LED] wavelengths pick up hemoglobin beautifully,” Rickman explained, “but when you think about blood sugar, lactates, and other metabolites, those LEDs don’t have the performance. They aren’t looking in the right part of the optical spectrum.”

Wearable health tracking like never before

Rockley Photonics describes its platform as a clinic on your wrist, bringing together the measurement of multiple different biomarkers, many of which may have previously required blood tests to assess, into a single, tiny, non-invasive sensor. Rickman explained why this is advantageous.

“When you measure one biomarker you get a one-dimensional picture of a person, but when you measure 10 biomarkers together, what’s contained in that relatively small amount of information can represent many different conditions the individual may be suffering from.”

It’s when you hear about how the silicon photonics-based sensor measures these biomarkers the complexity becomes clear.

“Hydration is understood by analyzing the difference in how your skin absorbs water and the lipids in your skin, and it’s that ratio we’re measuring. The spectrum of light is dominated by water, and that level goes up and down with your hydration. Until now the only other way to get this level of detail was by taking a blood sample. Core temperature is even more bonkers. We are able to measure it using another spectroscopic technique, as the water in your body, fortunately, changes its properties slightly with temperature, and we measure those changes using a gradient to supply us core body temperature readings.”

For blood pressure, the laser examines “bumps in the signal” after it sees peak pulse rates, which — depending on whether they are large or small — defines whether blood pressure is high or low. It sounds simple put like this, but Rickman said it’s very difficult for a laser to measure this accurately. Existing technologies can’t match this rich level of cardiovascular examination, and have therefore so far failed to get FDA approval. Rockley is currently in the process of gaining FDA approval for its platform.

What this means for you and me

Rockley’s sensor technology and platform aren’t science fiction. It’s all coming very soon, and although it’ll initially be available through a dedicated medical technology company, that could change in the not too distant future.

“We launch the first device in the fourth quarter this year,” Rickman confirmed. “It’s a wearable designed for the professional health care market, and we have announced our first customer, Medtronic, which is the world’s largest manufacturer of medical devices.”

However, it’s what’s coming after that we’re most interested in.

“We are working with six out of the top 10 wearable consumer tech companies in the world,” Rickman continued, “and we’re working on designs to find a way to fit [the sensor] into their wearable devices. We haven’t announced a volume contract with any of them yet. We’re hopefully likely to make some announcement about it at the end of this year.”

It’ll be a bit like a fitness tracker, but a million times more powerful

In a 2021 SEC filing, Rickman mentioned several consumer electronics brands known for smartphones as being interested in the sensor technology. The document also mentions a “long-standing development and supply agreement,” with a company that had already invested $70 million with Rockley. Numerous reports have claimed Apple has invested a total of $70 million in Rockley for research and development since 2017.

Whether the Rockley Photonics platform eventually makes it to an Apple Watch, at least in some form, is unknown, but the convergence of consumer health tracking and medical health tracking is clear. Rockley’s platform could add functionality previously only available through doctors, clinics, and using blood tests, to a normal consumer wearable. In Rickman’s mind, it’s not that far away, and like Movano’s Stacy Salvi said in a accurate Digital Trends interview, its arrival may change what the traditional consumer wearable looks like in the process.

“The type of wearable we’re producing for Medtronic doesn’t have a screen, it doesn’t tell you what your emails are. It’s purely dedicated to this rich functionality,” Rickman concluded. “It sits in the background just doing its job, but it still has a strap that can be changed and it’s easily cleaned. Maybe that evolves into a consumer device. It’ll be a bit like a fitness tracker, but a million times more powerful, in a format that will just sit in the background monitoring health. It’s another way of thinking about how it may arrive in the hands of consumers.”

Killexams : The Battery Show Wrap-up

Spending the better part of a week with more than 9,000 attendees at The Battery Show and Electric & Hybrid Vehicle Technology Expo 2019, in Novi, Michigan gives a pretty strong impression of where electrification of transportation is today, and more importantly, where it will be going tomorrow.

Growing Fast

First of all the show itself has grown—the Expo is now 20% larger than last year and more than 700 companies exhibit their products and technologies. There is an incredible variety of things to see—computer simulation software, battery test systems, connectors and cabling, battery packaging and venting systems, motors and controllers, chargers, and of course, battery cells and packs are on display. But, here is the thing—the days of garage hobbyists and “mom and pop” operations are gone. The battery and EV industries have become multi-billion dollar enterprises and the commercial professionals have taken over, and it shows.

Conferences and presentations at the show were divided into eight separate tracks and there were more than 150 speakers. Basic materials science, battery chemistry, charging systems, and EV market factors all get serious and critical examination by academic and industry experts. The talks are grouped into courses such as cell design, battery materials development, and EV and hybrid industry developments to aid show-goers in their choices.

Buses, Trucks, and Delivery Vehicles Lead The Way

Although EVs are still a very small part of the total automotive market in the US (between 2-3 %), there are certain segments that are beginning to show growth. During an Industry Leader’s Round Table on EV Growth, attendees learned that electric school buses are becoming popular. A school bus would seem in ideal EV application—the route is well-established, the speeds are low with lots of stop and go, and after an initial activity in the morning the bus sits unused (when it can recharge) until the end of the day. School districts are finding that the highly efficient electric buses can save, not only in fuel costs but also in reduced service and maintenance costs.

Another market that is rapidly growing is light delivery vehicles. FedEx, UPS, and others are buying fleets of electrically-powered trucks for urban package delivery. Once again, cost is the biggest driver as electrified trucks are proving themselves reliable and frugal in the field. The growing popularity of this segment was reflected in an increase in attendance in sessions dedicated to electrification of trucks and commercial and off-road equipment.

Can EVs Be Sustainable?

The growth of the personal EV market in the US is not quite as robust. Ford’s Senior Technical Leader Bob Taenaka provided a Keynote Address on how carmakers will deliver on customers EV demands. The same Topic was also addressed during an Industry Leader’s Roundtable dedicated to EV Sustainability. Auto industry analysts were questioned by actor, author, environmental activist, and noted electric vehicle early adopter Ed Begley, Jr. It was a wide-ranging discussion that included battery and vehicle costs, transitioning from current internal combustion gasoline-powered vehicles to EVS and how soon that is likely to occur in the US. Of particular interest was the conversation surrounding how automakers and unions will handle the disruption caused by vehicles that are much less labor-intensive to build, requiring fewer production-line workers. In addition, auto dealers will find their business changing dramatically, as the service requirements for EVs will be significantly less than current gasoline-powered vehicles.

New Materials

Research and development of new battery materials was also address in several session and during a Keynote Address by Mark Verbrugge, director, Chemical and Materials Systems Laboratory at General Motors. Verbrugge told his audience that a push toward Earth abundant materials and away from exotic elements could dramatically Improve both battery performance and cost.

Another innovation that could Improve battery performance was discussed during an Industry Leader’s Roundtable on Solid State Batteries. With representation from the University of Michigan, two battery manufacturers, and Ford and Toyota, the panel estimated production of the first solid state electrolyte batteries was just 3-5 years away. In fact, battery maker A123 broke the news during the session that it will convert its Romulus, Michigan battery plant to produce prototype solid state batteries before the end of 2019.

A Show of Optimism

Although the future of electrification of transportation in the US is complicated and difficult to predict, Design News editors detected a shared sense of optimism among battery show attendees. If nothing else, the number of new EVs that are scheduled to reach the market in the next year or two will provide more car-buying options—particularly as SUV and light truck EVs come available. There is also a strong consensus that battery cost will continue to fall and that a cost parity between EVs and gasoline-powered vehicle is just a couple years away. These factors, combined with many billions of dollars of investments by auto makers and suppliers means that electrification has moved from the fringes into an essential core part of the automobile industry.

The dates for The Battery Show and Electric & Hybrid Vehicle Technology Expo 2020, in Novi, Michigan will be September 15-17, 2020.
