Linear and angular position sensors

The new generation linear and angular position sensors from ZF pursue new ways in terms of efficiency. Based on a modular system, the sensor is available as an ANG version for angular position measurements or as a LIN-version for linear position measurements. Whereas the ANG-series adds to the existing range of angular position sensors, the linear position sensor opens a new scope for ZF customers. Possible for these sensors are applications such as hydraulic valves, hydraulic controls, electric drives, pneumatic controls, gear selection / shifting position, ride height and level position detection, throttle valve and pedal position, steering wheel position or as a zero-contact encoder alternative. IP68 classification makes these sensors universal also for use in rough environmental conditions. They comply with industrial / automotive EMC/EMI directives and come with a 12 Bit resolution. Due to the compact size the ANG- and LIN-series require less space than other sensors with a similar performance. The mounting Height is only 6.5 mm which is an extremely flat design for linear and angular position sensing. The LIN-series can measure a range of up to 45 mm, while the ANG series provide a programmable measuring range from 0° to 360° degrees. Due to the quality of the components used, both sensors come with an overall accuracy of ±2% full scale and a linearity of the output signal with ±1% full scale. Custom programming is available for: range, slope and PWM output thus allowing an excellent modification to individual requirements. No mechanical interface means no parts to wear out or jam. The LIN- and ANG-series sensors are non-contact linear position sensors with one or two independent outputs. The sensors operate through the use of Hall Effect technology with magnetic fields generated by permanent magnets. They provide a linear change in voltage output (ratiometric to the input voltage) corresponding to a linear displacement of the actuator magnet. The LIN-sensor includes an actuator magnet which specifically paired to the sensor and is required to assure proper operation. Both sensors are RoHS Compliant and suitable for wide air gap applications.

Portable sensor detects trace amounts of gluten in food at restaurants

For people with celiac disease or gluten intolerances, dining out can be stressful. Even trace amounts of the protein—found in wheat, barley, and rye—in a whole plate of food can cause adverse reactions.Now MIT spinout Nima—co-founded by CEO Shireen Yates MBA '13 and Chief Product Officer Scott Sundvor '12—has developed a portable, highly sensitive gluten sensor that lets diners know if their food is, indeed, safe to eat.According to the National Institutes of Health, celiac disease, an autoimmune disorder that leads to intestinal damage when gluten is eaten, affects around 1 percent of the U.S. population, or roughly 3 million people. According to the National Foundation for Celiac Awareness, millions more may suffer from nonceliac gluten intolerances.Nima's sensor, also called Nima, is a 3-inch-tall triangular device with disposable capsules. Diners put a sample of food—about the size of a pea—or liquid into the capsule, screw on the top, and insert the capsule into the device, which mixes the food into a solution that detects gluten. In two to three minutes, a digital display appears on the sensor, indicating if the food sample does or doesn't contain gluten.Every time someone runs a test, the result is automatically sent to an app Nima has developed. The diner can enter information about where and what they ate, and whether the food contained gluten. Any Nima user can log in to see the results.The aim is to create "a peace of mind at mealtime," Sundvor says. By amassing data on food, he adds, the startup hopes to provide people with better information about what they eat. "Right now, we don't know what's in our food, whether it is allergens, pesticides, or other harmful chemicals," he says. "There's not a good way to get that data. We want to give people the ability to understand their food better and how it affects their health."Sensitive sensorNima can sense gluten at 20 parts per million (ppm) or more, the maximum concentration for "gluten-free" foods as determined by the U.S. Food and Drug Administration.Nima's high sensitivity comes from the immunoassay inside the sensor, developed primarily by MIT chemical engineering alumnus Jingqing Zhang SM '12, PhD '13, who is now the lead scientist at Nima. The immunoassay contains custom antibodies that are highly sensitive to gluten molecules. When gluten is present, the antibody bonds to the gluten molecules, causing a color change in the immunoassay, which is captured by an optical reader. If any gluten is detected, the sensor will display an icon with a "gluten found" message. If the sample has less than 20 ppm of gluten, the sensor will display a smiley face.Nima can detect gluten in foods that are labeled as "gluten-free" but may have picked up microscopic amounts of the protein during the production or cooking process. A steak may have been fried on the same grill as gluten-based foods, for example, or a salad dressing may contain trace amounts of wheat flour. The device can even detect if someone touched a piece of bread that contained gluten, before handling the food in question. "It's the equivalent to finding a breadcrumb in an entire plate of food," Sundvor says.Moreover, Sundvor says, the device seamlessly integrates that chemistry with electronics and mechanics. "We've created this grinding, mixing, and extracting system, and together it works really well," he says.Filling the consumer gapNima was founded in 2013 as GlutenTech, when Yates, then an MIT Sloan School of Management student, dreamt up an idea for a portable gluten sensor. Seeking an engineer to bring the device to life, she met Sundvor, a recent MIT graduate who had studied mechanical engineering and product design.Together, they set up shop at the now-defunct MIT Beehive, a startup incubator on MIT's campus, with aims of filling "a huge consumer gap" in food-allergen testing, Sundvor says. Conventional at-home tests, he says, require equipment such as test tubes, pipettes, a mortar and pestle, and microscale. "You can't bring test tubes to a restaurant," he says.Sundvor began working long hours in an MIT machine shop building a prototype, while Yates brought the idea around to her MIT Sloan classes. Of note was a particular pricing class, where students sketched out pricing and demand models for the product. "The result of that was that I found there's a real opportunity here: There's a need and a willingness to pay," Yates says.In spring 2013, GlutenTech entered the MIT $100K Entrepreneurship Competition with a proof-of-concept model, and they earned the Audience Choice Award in the Accelerate contest. That summer, the team entered the Global Founders Skills Accelerator (GFSA), a 12-week startup program held at the Martin Trust Center for MIT Entrepreneurship.Participating in the $100K forced the team develop a business plan they could pitch to investors, Yates says. "It was a testing period to see, if we position ourselves in a certain way, will it resonate with investors?" she says."The GFSA was incredible," Sundvor adds, "It gave us the opportunity to have a safe space to go full-out on this for three months, have mentors, and have just enough money to squeak by."By the time the GFSA Demo Day rolled around in September, GlutenTech had its first working prototypes—"which were so ugly," Sundvor says, laughing.The 9-inch-long aluminum tubes "looked like lightsaber handles," Sundvor says. Inside the tubes were chemicals used in conventional food tests, and the system took about 10 minutes to detect gluten. When it did, a bright light flashed and a loud alarm went off. "We got many looks at restaurants," Sundvor says. "But they worked and got us our first investors."Three years ago, GlutenTech moved headquarters from Boston to San Francisco, and changed its name to 6SensorLabs. This year, they renamed the startup as Nima. In three years, the startup has gained more than $14 million in capital venture funding.New opportunitiesConsumers are the startup's first market. But as more individuals start using Nima, restaurants will have more data on their food to better serve patrons, Sundvor says. A couple of restaurants in San Francisco, in fact, are working with Nima on validating their gluten-free menu items.Next year, Nima plans to release two new sensors, one for peanuts and one for dairy, which is "surprisingly sneaky," Sundvor says. Bread at a restaurant, for instance, could have been fried in a pan with remnants of butter. "A lot of people are getting sick from dairy allergies, so that will be a big market," Sundvor says.Reference:LM50BIM3/NOPBDS18B20-PAR+T&RAD592BNZ

LEDs offering Excellent Lighting Solution for Industries and Streets

LED technology has evolved as very efficient solution for all our lighting needs in our homes, offices, parking lots, industries, streets and many other areas. However the application of LED as LED Industrial light, LED flood light and LED parking light is the biggest revolution as it has cut down the energy requirement significantly and offered a very durable lighting option that can last for years without needing replacement. The use of LED in industries and streets offers a very high quality lighting solution at reasonable cost. In fact, the lifetime cost of LED turns out to be much lesser than the HID lighting, which is gradually being replaced by LED. One of the main reasons for lesser lifetime cost is the long life of LED with very low power consumption. LED lighting offers a very promising solution for our future as the cost of LED will continue to drop as it has in the last few years because of the improving manufacturing techniques providing more efficient and cost effective production of LED for industries. LED light systems, like LED flood light systems offer many advantages over traditional lighting. Some of them are as follows: 1.    Extremely low power consumption2.    Long Life of Lights leading to excellent life for overall system3.    Excellent ability of color rendering according to the application 4.    Higher initial cost but better lifetime cost as compared to any other option.LED industrial light not only offers a very efficient alternative but also an environment friendly options that will help us cut down on the critical carbon emissions leading to a better future for the upcoming generations. The main reasons that make LED Industrial Lighting a perfect solution are as follows:Long Life: In terms of life expectancy, LED lighting turns out to be 20 times better as compared to the incandescent bulbs. The average life of LEDs is about 60,000 hours whereas a normal incandescent bulb lasts for about merely 1500 hours on an average. When compared to fluorescent bulbs. LEDs last 10 longer which is still a significant difference.Low Power Consumption: When it comes to power, LEDs offer a very efficient option with extremely less power consumption. It is estimated that by using LEDs in US, about 348 terawatt hours of electricity can be saved which costs huge amount of $30 billion. Better Distribution of Light: LED Lighting offers much better focusing properties which results in better distribution of light in the desired direction as compared to other sources of light which throws the light in every direction resulting into wastage of energy. Reference:ASMT-UYBG-NACJ8XRCWHT-L1-0000-004E6LCWW5AM-KXKY-4U8X

Transistors

Prototype of new transistor for lower power consumption

Researchers from the University of Twente MESA+ research institute, together with the company SolMateS, have developed a new type of transistor to reduce the power consumption of microchips. The basic element of modern electronics, namely the transistor, suffers from significant current leakage. By enveloping a transistor with a shell of piezoelectric material, which distorts when voltage is applied, researchers were able to reduce this leakage by a factor of five (compared to a transistor without this material). An article presenting the prototype of the transistor appears in the June issue of IEEE Transactions on Electron Devices, an authoritative scientific journal in the field of transistor research.Current leakage in transistors is one of the causes of battery depletion in portable electronic devices, such as smartphones and laptops. With the new type of transistor, either the current leakage (while the transistor is not active) or the energy consumption (while the transistor is active) can be addressed. In the latter case, it is estimated that energy consumption can be reduced by approximately 10%.Intelligent squeezingThe trick lies in a piezoelectric material which is applied to the exterior of the transistor. The piezoelectric material expands when you apply a voltage to it and compresses the silicon in the transistor with a pressure of about 10,000 atmospheres. This high pressure ensures that electrons flow through the transistor faster. You can therefore make microchips more efficient by 'intelligently squeezing the transistor'.Incidentally, existing transistors are already put under high pressure in order to improve their efficiency. In this case, however, the pressure is permanently built in, which actually increases the current leakage. In the prototype designed by the UT, the transistor is only put under pressure when required and this makes a big difference. The electric current needed to switch the transistor from on to off is thereby partly replaced by mechanical tension.CrudeAccording to dr. ir. Ray Hueting from the chair Semiconductor Components, this is an initial prototype that can already produce energy savings. "The design is still fairly crude where the material is concerned. With the further development of the transistor, it should therefore be possible to achieve a further significant increase in efficiency."The operating principle of this transistor was theoretically predicted in 2013 by the same research group. But in advance it was by no means certain that the transistor would be a success. The reason for this is that piezoelectric materials and silicon (which transistors are made of) are difficult to combine. The researchers solved this by inserting a buffer layer between the two materials.
