There was a time when being an engineering student meant you had a sword. Well, really it was a slide rule hanging from your belt, but it sounds cooler to call it a sword. The slide rule sword gave way to calculators hanging from your belt loop, and for many engineers that calculator was from HP. Today’s students are more likely to have a TI or Casio calculator, but HP is still in there with the HP Prime. It is hard to call it a calculator since the latest variant has a 528 MHz ARM Cortex A7, 256 MB of RAM, and 512 MB of ROM. But if you can’t justify a $150 calculator, there are some cheap and even free options out there to get the experience. To start with, HP has a free app that runs on Windows or Mac that works just like the calculator. Of course, that’s free as in no charge, not free as in open source. But still, it will run under Wine with no more than the usual amount of coaxing.

You might wonder why you need a calculator on your computer, and perhaps you don’t. However, the HP Prime isn’t just your 1980s vintage calculator. It also has an amazing number of applications including a complete symbolic math system based on xCAS/Giac. It is also programmable using a special HP language that is sort of like Basic or Pascal. Other applications include plotting, statistics, solvers, and even a spreadsheet that can hold up to 10,000 rows and 676 columns.


It is easy to think that HP provides the free PC software so you’ll go out and buy the real calculator, and that may be part of it. However, you can also get official apps for Android and iOS. They aren’t free, but they are relatively inexpensive. On iOS the cost right now is $25 and on Android it is $20. There are also “lite” versions that are free.

It appears that these apps are not emulating the real calculator hardware, but are ports of the calculator code. So this isn’t a case of someone just writing a pretend calculator, these apps act like the real calculator because it is running the same source code. For example, there is an application, HP Connectivity Kit, that lets you talk to a real calculator over the network. The PC and phone versions will also connect just like a real device.


You can write programs on the device or if you have the HP Connectivity software (also free) you can write programs on your PC. You can even find some from the Internet. If you miss your old calculator, there is a define feature that lets you program like a key macro recording.

The programming language isn’t hard to pick up. Here’s a short snippet:

LOCAL N1, N2, L1;
CHOOSE(N1, "Area or Volume?", "Area", "Volume");
IF N1 == 1 THEN
CHOOSE(N2, "Choose shape", "Rectangle", "Triangle", "Disk");
CHOOSE(N2, "Choose solid", "Prism", "Cylinder", "Cone", "Pyramid", "Sphere");
. . .

Hacking and What’s Next?

You’d think that the real hardware would be a prime platform for hacking, but so far that’s still on the to-do list. The only really good hardware hack for the real calculator adds a Samsung battery with a higher capacity to the machine. There are also some enticing pads on the PCB that appear to support a buzzer and I2C communications, but there’s no firmware for it. There have been a few attempts to load alien firmware into the device, but there’s no full-blown development system. Getting to the JTAG port looks pretty intense. There’s also been the inevitable hacking of the communication protocol.

History is replete with products that seemed amazing for their day but turned out to be just a stopgap for something better. Cassettes gave way to CDs and then CDs gave way to digital music. Telephone answering machines gave way to voicemail. Calculators have that feel to them. How much longer will we need them? Are the virtual HP Prime applications going to overshadow the physical device?

Regardless, the Prime is state of the art and would shame a personal computer from a few years ago. You can only wonder if it will be the last great calculator, or if there are more yet to come. And a calculator still makes a nice project. Not all homemade calculators are simple.

Killexams : Ford’s Powershift Debacle

In the automotive world, change is a constant, and if you’re not keeping up, you’re falling behind. New technologies and methodologies are key to gaining an edge in the market, and companies invest billions each year trying to find the next big thing, or even the next minor incremental improvement.

In just such a quest, Ford Motor Company decided to explore an alternative to the traditional automatic gearbox, aiming for greater fuel efficiency in their small cars. On paper, there were gains to be had. Unfortunately, not everything went according to plan.

The Concept

The dual-clutch gearbox promised fuel economy improvements, as well as lighter weight and easier assembly.

The traditional torque-converter based automatic gearbox was a game-changer for the automotive world. With the advent of the self-shifting transmission, drivers had one less complex skill to learn, and cars became much less taxing to drive, particularly in high-traffic, slow-speed environments.  However, the fluidic coupling of an automatic transmission isn’t as efficient as simple meshing gears, a tradeoff that harms fuel efficiency. To get around this, Ford instead decided to create a dual-clutch automated manual transmission for its small cars.

Dual-clutch transmissions use a pair of clutches, one for odd-numbered gears, and another for even numbered gears. As the car accelerates in one gear, the transmission can preselect the next gear, and then engage the opposite clutch while slowly disengaging the other. This allows for nearly-instantaneous shifting while maintaining torque output to the driven wheels for the duration of the shift. Finding their first road application in high-performance supercars in the 90s, the technology has slowly trickled down to cheaper vehicles over time. Most dual-clutches, particularly those for high-torque applications, use a wet clutch system, where the clutch plates are bathed in oil. Ford wished to maximise fuel efficiency, and instead chose to go with a dry clutch system. The dry clutch eliminates pumping losses from the oil in the transmission.

The Problems

What in the world are you thinking going with a dry clutch?

With an eye firmly fixed on improving fuel economy numbers, the Powershift transmission was pushed through development, to be installed on the 2011 Fiesta and 2012 Focus models. In the lead up to production, problems were already apparent to Ford engineers, who were struggling to calibrate the transmission’s computer controls to allow the vehicles to drive smoothly and safely.

An email sent prior to the launch of the 2012 Ford Focus featuring the Powershift transmission, indicating Ford engineers were well aware of problems prior to cars going on sale. Source: Detroit Free Press

Early pre-production testers had issues with launches from a stop and shift quality. Often, vehicles would lurch violently when taking off from traffic lights, or shudder under power. Efforts were made to solve the problems in software, with tricks used to modulate the clutch engagement to try and better control the torque delivery. Unfortunately, none of the fixes stuck. The dry clutch system faced fundamental problems, with the inconsistent friction coefficient making it difficult to program the transmission controller in a way that could keep things running smoothly.

In a parallel to another automotive engineering disaster, the Takata airbag fiasco, Ford were well aware of the issues with the transmission prior to launch. In one document presented to court, a product development engineer emailed colleagues outlining issues with the transmission’s performance. Launches were a particular issue, with the email being sent just six months prior to launch of the first Focus models to feature the transmission.

Cars fitted with the Powershift transmission would often suddenly shift into neutral, causing dangerous situations for drivers.

Despite this, the company pressed on, and millions of vehicles were sold with the Powershift transmission fitted. In a short period, complaints began to flood into the NHTSA. Particularly of concern was the tendency to suddenly shift into neutral when there was a loss of communication or other fault with transmission components. This behaviour was not considered as inherently dangerous by Ford, as the driver would still have full control over steering and braking systems.

In the face of this complacency, incidents continued to stack up. Cars returned to dealerships time and again for repair, with no proper fix available. Crashes began to implicate the Powershift transmission. Drivers reported cars lurching forward in parking lots into stationary objects, to being rear-ended due to a sudden loss of drive on the highway. Several fatal accidents have been attributed to the transmission by victim’s families. However, due to the complex nature of the incidents involving a loss of control, proving this as a definitive cause has been difficult. Ford have declined to accept the allegations in these cases.

The Cost

With millions of vehicles fitted with the Powershift transmission, the inevitable result was a series of lawsuits against Ford. Class actions were undertaken in the United States, Australia, and Canada. In many cases, Ford initially declined to offer refunds or replacement vehicles at no cost, leading to a backlash from regulators. Eventually, Ford elected to settle in most cases, with warranties extended for Fiesta and Focus models fitted with the affected transmissions.

The fallout was a massive reputational hit to Ford, with following models of the Fiesta and Focus returning to a standard torque-converter based automatic transmission. The high cost of repeated transmission repairs also weighed on Ford in warranty costs, estimated to be to the tune of $700 million.

One wonders whether the cost of a late-stage switch back to a more traditional automatic gearbox would have been cheaper in the long run. In addition to causing less inconvenience and heartache to customers, the lower warranty costs and improved reputational standing are worth considering. It’s likely that Ford has had a stern, hard look at internal policies in the years since to determine just why such a defective transmission was allowed through to production. As always, it pays to get your quality assurance out of the way early, before sending millions of defects down the production line and out into the world.

Killexams : 26 best August sales on school supplies and more

Select is editorially independent. Our editors selected these deals and items because we think you will enjoy them at these prices. If you purchase something through our links, we may earn a commission. Pricing and availability are accurate as of publish time.

In many places, August heralds the end of summer and the beginning of the school year for students and parents alike, which means end-of-season sales on outdoor items and office supplies from a wide range of stores. The retail landscape is also changing significantly: While Walmart’s been slashing prices to clear out excess inventory, we’ve also seen price increases due to inflation. And though most surveyed Americans think a recession is likely within the next year, the National Retail Federation reports they’re still spending money.

SKIP AHEAD Best August deals | What to buy in August | What to skip in August

With big words like “inflation” and “recession” at the top of mind, shoppers should think smartly about their purchases. “Bundling items and buying in bulk can certainly be a smart money-saving tactic for bigger families or groups of friends that divvy up items, from value packs and 2-for-1 promos,” said Vipin Porwal, consumer savings expert and founder of cashback browser extension Smarty. While some Americans are still shopping, others may opt to reuse backpacks or wait until holiday sales to buy new technology, thanks to inflated prices, Porwal said. He predicted those that do shop will be creative with how they take advantage of deals this month.

With that in mind, you — like many shoppers — may be hunting for deals, bulk sales and discounts before making a purchase. To deliver you an idea of the best sales and discounts during the month ahead, we consulted retail experts on what sales and items are worth considering, as well as what’s not worth shopping for right now (if you can wait).

What to buy in August

August should be about upgrading the whole family — even as sales target students — according to Porwal. Experienced shoppers know there are big savings during Back to School and end-of-season sales this month, he said, which include deals on school supplies but also home items. These deals may include traditional school supplies like backpacks and pens, or technology like tablets and laptops for student usage. Traditionally, dorm décor and necessities like pillows, shower curtains, and trash cans go on sale around this time of year, too.

Porwal also noted there are some “savings opportunities that get overlooked” around this time. He said to anticipate “deep discounting” on dark-horse categories like musical instruments, prescription eyewear and exams and home and office technology like printers, computer monitors, software packages, and internet networking gear.

End-of-season deals have historically included discounts on outdoor equipment like tents, grills, hammocks, and camping chairs, as well as patio furniture. During the last week in August, Porwal advised, shoppers will likely see pre-Labor Day sales, with discounts up to 50% off sporting and outdoor items, swimwear and yard supplies, as well as other seasonal outdoor items.

What to skip in August

If you’re looking for video game consoles, TVs and other electronics, Porwal suggested waiting until early Black Friday deals, “when nearly every retailer features these items at their lowest prices.”

Additionally, Porwal mentioned that jeans and denim products may be discounted this month but should be at lower prices as the seasons change.

Killexams : Echocardiographic deformation imaging reveals preserved regional systolic function in endurance athletes with left ventricular hypertrophy

Background Left ventricular hypertrophy (LVH) is often observed in athletes, which should be differentiated from hypertrophic cardiomyopathy. The aim of the study was to explore the functional changes measured using tissue Doppler imaging (TDI) deformation analysis in athletes fulfilling LVH criteria participating in different endurance sports.

Methods Healthy controls (n = 62, 58% men) and endurance athletes (n = 120, 62% men) aged 18–40 years were prospectively enrolled and underwent both standard echocardiography as well as TDI. Longitudinal TDI-derived strain and strain rate (SR) were calculated in the septal and posterior wall in three segments. LVH was defined as a left ventricular mass (LVM) over 132 g/m2 in men and over 109 g/m2 in women.

Results Echocardiographic LVH was observed in 33 athletes (67% men). LVM was significantly increased in both athlete groups (102.6 g/m2 (SD 16.0) and 135.7 g/m2 (SD 15.9) vs 88.0 g/m2 (SD 16.5) in controls, p<0.001). Diastolic parameters were not significantly different between groups. Athletes with LVH showed no significant difference in strain and SR values in any segment of the septal or posterior wall compared with controls or those without LVH. A weak but significant correlation (also after multivariate analysis) was found for septal wall thickness and LVM in peak systolic strain (r = 0.26, p<0.01 and 0.23, p<0.01) and SR (r = 0.27, p<0.01 and 0.29, p<0.01). Nevertheless, strain and SR values were still within normal limits in all athletes.

Conclusion Athletes with LVH overall show normal deformation values in the left ventricle. These data suggest that a moderate reduction in regional septal deformation should not be considered as pathological when evaluating the endurance athlete with echocardiographic LVH of unknown origin.

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.

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 deliver 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 Center for Integrative Neuroscience

This MRI Facility houses a new Siemens 32-channel 3T Skyra (Siemens Healthcare, Germany) and a Philips 32-channel 3T Ingenia (Philips Medical Systems, The Netherlands). Both scanners have wide bores and are equipped with MR-compatible technologies for conducting experiments with human subjects. The Philips system has been used by up to ten labs over the course of five years; it will be phased out later this year and the Siemens will be used for most if not all current and future scanning. In addition to high resolution images of brain anatomy (structural MRI or sMRI), both scanners support functional MRI (fMRI) and diffusion imaging of long-range white matter tracts, and thus adequately support all UNR neuroimaging needs.

"Functional" MRI (fMRI) differs from high-field strength "structural" MRI (sMRI) by its ability to image beyond anatomical detail into the functional workings of the brain, how the brain thinks, and where it all takes place. The specific type of fMRI being utilized in these research projects is known as "BOLD" fMRI, more scientifically known as "neurovascular coupling". As important and exciting as all of this is, there are also other techniques that fall under the general heading of fMRI as well.

Fractional anisotropy (FA), featuring directionally color-coded fiber tracts, can map out deep white matter axonal pathways which connect all of the eloquent sites in the brain identified with the BOLD fMRI. The FA maps can easily be converted into Diffusion Tensor Images (DTI) in which the exquisite neuroanatomy of the connections in the brain are displayed and studied.

MR Spectroscopy (MRS) and Perfusion MRI (pMRI) also fit under the heading of fMRI. MRS deals with in vivo examination of hydrogen spectra in selected regions of brain, while pMRI allows assessment of the amount of blood flowing into and through any portion of brain anatomy. 

The Siemens 32-channel 3T Skyra system is fully equipped (as of Fall 2019) for advanced neuroimaging, and in many ways surpasses the capabilities of the Philips Ingenia system. This Siemens system has a fast gradient system that provides high-speed spatial encoding, a 64-channel data acquisition system with digital wireless technology to Improve SNR and temporal stability, and a dual-channel RF transmitter system for reduction of dielectric effects, and more flexible RF pulse design. The gradient rise time (200 mT/m/ms), peak gradient strength (45 mT/m per axis), and duty cycle (100% using full gradient strength on all three axes) are the highest specifications in the industry for whole-body systems. Also, the gradients have a balanced geometric design that results in less acoustic noise generation. Every hardware and software option that Siemens offers for neuroimaging is installed on this MRI system. Parallel imaging capabilities in one and two-dimensions enable EPI acquisitions at higher temporal resolution and with less geometric distortion. In addition, a Master Research Agreement with Siemens Healthcare makes available advanced "works-in-progress" pulse sequences for EPI and structural neuroimaging to deal with specific technical challenges.

The Siemens system is equipped with fMRI-presentation hardware, screen and response pads. It is also equipped with a vPixx eye-tracking system. The TRACKPixx3 MRI/MEG is a 2 kHz eye/gaze-tracking solution compatible with MRI and MEG environments. The TRACKPixx3 is versatile, supporting both monocular and binocular tracking with a single mechanical configuration. The TRACKPixx3 does not require a dedicated PC to process eye images and generate gaze information; all image processing is performed within the TRACKPixx3 hardware. Gaze data can be logged within the TRACKPixx3 and retrieved by the testing PC with a simple low-latency USB interface. The TRACKPixx3 video feed can be accessed directly through a console display for real-time visualization and adjustment of the tracker. A scene camera can be connected to the tracker to monitor the experiment. These video feeds can also be accessed through the USB interface for remote control of the TRACKPixx3.

The Philips Ingenia 3.0T system comes with a dStream digital broadband architecture and a channel independent RF technology, which results in an up to 40% more SNR. dStream digitizes the signal right in the coil, eliminating noise influences typical of analog pathways, to capture the MR signal without predistortion or compression. A fiber-optic connection from the coil to the image reconstructor enables lossless broadband data transmission. This Ingenia 3.0T system has a higher order shim function which offers advanced shimming capabilities to obtain improved image quality in field-sensitive applications and techniques such as single-voxel spectroscopy, chemical shift imaging, single-shot EPI and balanced FFE. This Ingenia 3.0T system features high performance whole body, non-resonant, self-shielded gradient technology with new amplifiers that deliver high peak and slew rates for the demanding requirements of the latest and emerging clinical imaging techniques. The Quasar Dual gradient system provides industry leading performance specifications for peak strength and slew rate with a dual mode capability that optimizes advanced applications requiring very high peak mode capabilities. The maximum gradient amplitudes and slew rates corresponding to the dual mode are 80 mT/m, 100 mT/m/ms and 40 mT/m, 200 mT/m/ms respectively. This Ingenia 3.0T system has a multiple RF sources, which adapts the RF signals to suit each individual patient. This results in a faster scan, enhanced image uniformity/consistency, over a broader range of applications. This Ingenia 3.0T system features MultiBand SENSE which allows you to use state-of-the-art acceleration factors in the brain by simultaneously exciting multiple slices. Due to a shorter minimum TR for fMRI, larger anatomical coverage or higher temporal resolution can be used. In the DWI/DTI sequences larger anatomical coverage or higher number of diffusion directions can be acquired. With MultiBand SENSE, fMRI and DTI exams can be performed with high speed and high resolution, simultaneously.

This Ingenia 3.0T system is equipped with a Multi-nuclear spectroscopy (MNS) system, which provide the ability to perform 13C, 31P, 7Li, 23Na, 19F and other nuclei spectroscopy and imaging. The multiple RF amplifiers in this system includes two 18 kW solid-state 1H channel narrowband amplifier and one 4 kW broadband (10-130 MHz) Multi-nuclear amplifier.

This Ingenia 3.0T system has a bore diameter of 60 cm and provides a full-size 50 cm field-of-view. Analog to digital signal conversion on the coil, 70cm bore, multi-transmit, Omega HP Gradients (slew rate 200 mT/m/ms, maximal gradient strength 45 mT/m), unlimited RF channels, fMRI-presentation hardware, screen and response pads.
