American Aerospace Controls (AAC) has announced its complete line of high-reliability standard and custom electrical transducers for rail, heavy locomotive, high-speed train and light rapid transit monitoring. AAC current transducers help rail and locomotive OEMs and their associated design and test engineering personnel to meet stringent EN50155, EN50121 and MIL-STD-202 standards.
The study helps to confirm the idea that the surface of Phobos contains tons of dust, soil, and rock blown off the Martian surface by large projectile impacts. Phobos' orbital path plows through occasional plumes of Martian debris, meaning the tiny moon has been gathering Martian castoffs for millions of years.
Son of Blackbird: Lockheed Martin's Skunk Works has recently revealed its plans for a hypersonic aircraft that will go twice the speed of the SR-71. The SR-72 twin-engine aircraft is expected to travel at Mach 6, with the ability to strike targets. At this speed, no enemy would have time to react or hide.
The next generation of gaming is nearly here, but what about the generation after that one? Sony and Microsoft are launching their new super-powered consoles in the coming weeks. However, gamemakers at last week's Game Developers Conference Next in Los Angeles were already contemplating outside-the-box innovations...
The European Space Agency says one of its research satellites re-entered the Earth's atmosphere early Monday on an orbit that passed over Siberia, the western Pacific Ocean, the eastern Indian Ocean and Antarctica. The 1,100-kilogram (2,425-pound) satellite disintegrated in the atmosphere but about 25 percent of it...
Behlman Electronics has introduced two new power factor corrected AC Power Sources / Frequency Converters. These carry the CE Mark essential for users in member states of the EU and EFTA countries Iceland, Norway, Switzerland and Liechtenstein, plus Turkey.
Microvehicles and other devices that can change shape or move with no power source other than a beam of light may be possible through research led by the University of Pittsburgh. The researchers are investigating polymers that "snap" when triggered by light, thereby converting light energy into mechanical work....
The family of a Silicon Valley engineer who amassed one of the nation's most extensive historic military vehicle collections is giving the tanks, missile launchers and armored vehicles to a Massachusetts-based museum that will preserve and display some of them.
Merit Sensor Systems announced its TR Series temperature-compensated pressure sensor product line. The TR Series packaged pressure sensor features Merit Sensor’s “back-side entry” approach, where the sensing media cannot come in contact with the active, top side of the pressure sensing die.
TT electronics is further extending its range of innovative solutions for challenging applications, with the introduction of three families of thick-film precision resistive dividers targeting high-voltage measurement circuits. The new devices are being launched in response to growing demand in the energy, medical, industrial and instrumentation markets.
OLEDs are already used in the displays of smart phones or digital cameras today. They offer an especially bright image with high contrast, but come with a serious drawback: typically, only one quarter of the electrical energy invested in running the device is actually converted into light.
Recent advances in robotics technology make it possible to create prosthetics that can duplicate the natural movement of human legs. This capability promises to dramatically improve the mobility of lower-limb amputees, allowing them to negotiate stairs and slopes and uneven ground, significantly reducing their risk of falling as well as reducing stress on the rest of their bodies.
As scientists develop the next wave of smartwatches and other wearable computing, they might want to continue focusing their attention on the arms and the wrists. According to a recent Georgia Tech study, portable electronic devices placed on the collar, torso, waist or pants may cause awkwardness, embarrassment or strange looks.
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage...
Littelfuse, Inc. has added two new packaging options to its SP3012 Series TVS Diode Array (SPA® Diodes) line. Like the rest of the series, these new devices are optimized for protecting sensitive chipsets with high-speed data lines from external ESD (electrostatic discharge) events. The new SP3012-03UTG (uDFN-6) and SP3012-04HTG (SOT23-6) devices offer board designers more options and greater layout flexibility. They also provide up to 66 percent greater clamping performance than other industry options, ensuring greater chipset reliability.
Narrow stripes of dirt and rock beneath massive Antarctic glaciers create friction zones that slow the flow of ice toward the sea, researchers at Princeton University and the British Antarctic Survey have found. Understanding how these high-friction regions form and subside could help researchers understand how the flow of these glaciers responds to a warming climate.
More than 600,000 of the mammals may have died in 2012 in the contiguous United States. A new estimate of bat deaths caused by wind turbines concludes that more than 600,000 of the mammals likely died this way in 2012 in the contiguous United States.
Would-be donors skip giving when offered the chance to show public support for charities in social media, a new study from the University of British Columbia's Sauder School of Business finds. "Charities incorrectly assume that connecting with people through social media always leads to more meaningful support," says Sauder PhD student Kirk Kristofferson, who co-authored the forthcoming Journal of Consumer Research article.
Every so often, you see a robot on the internet that is so macabre-looking it belongs in a horror film. There is a quality about these robots that’s not quite robot, but not quite human. Generally, in the technology community, nine out of ten of these robots come out of the Department of Defense sponsored Defense Advanced Research Projects Agency (a.k.a DARPA). (If you need proof, check out DARPA’s PETMAN)
The DATEL Business Unit of Murata Power Solutions announced the introduction of a new line of digital-to-analog converters. The reliable DAC-88 series are 12-bit, 3µs DACs housed in a small hermetically sealed 24-pin DDIP or SMT gull-wing ceramic package.
Imagine upwards of eight tons pressing down on your body as you make the descent into the icy waters of the deepest parts of the ocean. The human body isn’t meant to withstand that sort of pressure, so we must utilize devices like the OpenROV to get our exploration fix if we don’t happen to have millions of dollars on hand for more sophisticated equipment.
Carnegie Mellon University computer scientists have developed a new password system that incorporates inkblots to provide an extra measure of protection when, as so often occurs, lists of passwords get stolen from websites. This new type of password, dubbed a GOTCHA, would be suitable for protecting high-value accounts...
Georgia Tech warns of threats to cloud data storage, mobile devices in latest 'emerging cyber threat'November 7, 2013 1:40 pm | by EurekAlert! | News | Comments
As more businesses find their way into the cloud, few engage in security measures beyond those provided by the associated cloud storage firm, a new report from Georgia Tech notes. Even fewer seek heightened data protection because of concerns that usability and access to remote data would be significantly reduced.
A pair of University of Cincinnati researchers has seen the light – a bright, powerful light – and it just might change the future of how building interiors are brightened. In fact, that light comes directly from the sun. And with the help of tiny, electrofluidic cells and a series of open-air "ducts..."
Richardson RFPD, Inc. announces immediate availability and full design support of the new mXTEND antenna booster from Fractus, S.A. (Fractus). The mXTEND (part number FR01-S4-250) is specifically designed to provide multiband performance in mobile and other wireless devices....
