University of Utah engineers designed microscopic mechanical devices that withstand intense radiation and heat, so they can be used in circuits for robots and computers exposed to radiation in space, damaged nuclear power plants, or nuclear attack.
A team of Case Western Reserve University engineers has designed and fabricated integrated amplifier circuits that operate under extreme temperatures—up to 600 C—a feat that was previously impossible. The silicon carbide amplifiers have applications in both aerospace and energy industries.
Thanks to new energy taxation regulations taking effect in Germany, electrical engineers there have invented a space-saving energy usage metering unit that can be simply clipped onto a power cable like a laundry peg, without having to disconnect the load. The device is based on a magnetic field sensor originally developed for use in washing machines, where it monitors the position and orientation of the rotating drum.
Researchers from Michigan State University, the NIST Center for Neutron Research, and the NIST Center for Nanoscale Science and Technology have discovered the key to controlling and enhancing the lossless flow of a current with a single electron spin state in a standard superconducting device.
Light-emitting diodes (LEDs) at infrared wavelengths are the magic behind such things as night vision and optical communications. Cornell University researchers have advanced the process of making such LEDs cheaper and easier to fabricate, which could lead to ultrathin LEDs painted onto silicon to replace computer wiring with light waves.
Electric vehicles have slowly been catching on in urban environments, but their popularity has been hampered by available manufacturing technology. Either the vehicles are too heavy and too expensive, or they do not meet mass-market safety requirements. Researchers in Germany, funded by major automotive corporations, are testing a new mobility concept they hope will hit the sweet spot.
Schaefer, Inc., has broadened capabilities for its Raptor Series of military COTS/MOTS power supplies. The output voltage range has been extended to provide DC outputs from 12 VDC to 52.5 VDC with power ratings from 1200 W to 1800 W.
Globalization, the personal computer, and changing priorities set the stage for R&D 100 Award Winners.
Philips recently announced that its EnduraLED 12.5 W bulb has met or exceeded the quality and energy efficiency requirements for a 60 W light-emitting diode (LED) equivalent set forth by the Environmental Protection Agency’s Energy Star program. Philips was the only company to enter the Department of Energy’s L Prize contest, which sought a product like the EnduraLED.
Last Friday, the National Science Foundation held a congressional briefing to call attention to its research successes, particularly the process of bringing relevant fundamental research from the laboratory to the marketplace. Particular attention was called to Small Business Innovation Research grant beneficiaries, some of whom shared their success stories at the briefing.
Equipped with an advanced sensing and navigation suite of instrument, the Shipboard Autonomous Firefighting Robot (SAFFiR) is the product of a interdisciplinary team and is designed solely to fight fires aboard U.S. Navy and Marine Corps vessels. A humanoid-type robot was chosen because it was deemed best suited to operate within the confines of an environment that was deigned for humans in the first place.
A group of Italian and Swedish researchers appears to have solved the problem of radio congestion by cleverly twisting radio waves into the shape of fusilli pasta, allowing a potentially infinite number of channels to be broadcast and received. To demonstrate, they did this in real-life conditions by beaming two corkscrewed radio waves across the waters of Venice, Italy.
Visible Light Communications (VLC), a University of Edinburgh spin-out, will soon launch its first prototype light-emitting diode communications technology. “Li-Fi” relies on optical spatial modulation and an Internet protocol technology to allow LED light to carry optical wireless communications streams.
Sandia National Laboratories has developed an experimental smart outlet that autonomously measures, monitors, and controls electrical loads with no connection to a centralized computer or system. The goal of the smart outlet and similar innovations is to make the power grid more distributed and intelligent, capable of reconfiguring itself as conditions change.
As integrated circuits and environmentally friendly technologies emerged, R&D 100 Award winners set the pace.
Not all artists are extroverts. A portraitist at the CeBIT show in Hanover, Germany, this week is cool, precise, and metallic. Other artists, in fact, helped it get started as a project to test image-evaluation technologies that equips the robot with a sense of “sight”.
Most electric motors and generators operate in just one direction. There's no real need for them to go into reverse, but they’ve been designed to work both ways. Dionysios Aliprantis of Iowa State University wants to change that, incrementally chipping away at motor design and optimize performance in just one direction.
Sometimes total electrical isolation is a good thing—and that's the idea behind a power-over-fiber communications cable being developed by engineers at Sandia National Laboratories. The Sandia team is developing a hybrid cable design that uses fiber to send and regulate optical power to the communications electronics integral to the cable. A patent is pending on the design.
After comparing light-emitting diodes against fluorescent lights in meat refrigeration units, Kansas State University’s Kyle Steele found that retailers could save a substantial amount of money by using them, and not just because of the LEDs’ operating efficiency.
A team in Germany has built a transmitter less than a millimeter square that has generated the highest frequency ever attained by a microelectronic device: 1.111 THz. Compared to previous transmitters that have been bulky and expensive, the new device could soon find use in engineering applications.
Researchers have created a new type of optical device, the passive optical diode, small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.
A team of University of Illinois engineers has developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink. Their solution was to adapt a microcapsule healing solution used for polymers to conductive systems.
Atomic force microscope cantilever tips with integrated heaters are widely used to characterize polymer films, and to study fundamentals of nanometer-scale heat flow. Until University of Illinois engineers adapted such a tip to read electrothermal voltage, however, no one had used a heated nano-tip for electronic measurements.
Researchers at Rochester Institute of Technology and PPC Corp., Syracuse, N.Y., have developed a new sensor that, once installed in the connecting units of coaxial cables, can find the exact location of cable damage through a technology called back scatter telemetry.
