The International Telecommunication Union, which coordinates global radio spectrum use, recently came to an agreement that provides specific radio frequency bands for ocean radars, which until now operated only on an informal basis and were subject to immediate shut-down if they caused interference with other radio systems. The new technology may eventually make real-time detection of tsunamis and oil spills possible.
Featuring a resolution of 1,600 by 1,200 pixels coupled with high-grade optics, Bruker’s e-FlashHR electron backscatter detection (EBSD) system is able to display fine pattern details, making it useful for the analysis of fine-grained and/or nonconductive materials, nanomaterials, and for use at low beam current and accelerating voltages.
The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers at the University of Pennsylvania are pushing circuitry forward in a different way, by replacing electricity with light.
Sometimes knowing that a new technology works is not enough. You also must know why it works to get marketplace acceptance. New information from NIST about how layered switching devices for novel computer memory systems work, for example, may now allow these structures to come to market sooner, helping bring about faster, lower-powered computers.
A new implantable sensor developed at Rensselaer Polytechnic Institute can wirelessly transmit data from the site of a recent orthopedic surgery. Inexpensive to make and highly reliable, this new sensor holds the promise of more accurate, more cost-effective, and less invasive post-surgery monitoring and diagnosis.
Georgia Institute of Technology's Tongue Drive is a wireless device that enables people with high-level spinal cord injuries to operate a computer and maneuver an electrically powered wheelchair simply by moving their tongues. The newest prototype of the system allows users to wear an inconspicuous dental retainer embedded with sensors to control the system.
Discera, a maker of micro-electrical mechanical systems (MEMS)-based timing solutions based in San Jose, Calif., has entered into a distribution deal with Avnet Electronics Marketing Americas, an operating group of Avnet, which distributes computer products, electronic components and embedded technology to customers in over 70 countries.
Ditching satellites and complex, powerful computers and opting for camera technology inspired by small mammals may be the future of navigation systems. A Queensland University of Technology faculty member is researching ways to make more reliable global positioning systems (GPS) using camera technology and mathematical algorithms, which would make navigating a cheaper and simpler task.
Near-Earth space is full of junk. NASA keeps close tabs on at least 16,000 objects larger than 10 cm in diameter. In an effort to tidy up the mess, the Swiss Federal Institute for Technology (EPFL) is building an $11 million satellite called CleanSpaceOne that will force debris toward Earth, burning it up in the atmosphere.
As integrated circuits and environmentally friendly technologies emerged, R&D 100 Award winners set the pace.
To keep energy consumption under control, future chips may need to move data using light instead of electricity—and the technical expertise to build them may reside in the United States, according to a Massachusetts Institute of Technology study.
The latest addition to computing power at Fermi National Accelerator Laboratory is a 45-teraflop cluster of graphics processing units (GPU) that scientists use to explore the properties of the strong nuclear force. The GPU nodes power through data faster than any other computing nodes at more than five times the rate of the processing units of the previous generation.
NASA scientists are in the midst of preparing their Space Communications and Navigation (SCaN) Testbed for launch later this year. Its mission will be to push the limits of software-defined radio, a communication system in which components typically implemented in hardware are instead provided by means of software.
Researchers at the University of Copenhagen have developed a new nanotechnology platform for the development of molecule-based electronic components using graphene. At the same time, they have solved a problem that has challenged researchers from around the world for ten years.
New and better ways of measuring high-tech energy consumption could lead to significant environmental and economic gains, a study from The Australian National University (ANU) has found. Researchers from ANU, the University of Texas at Austin, and the University of Washington have completed the first systematic profile of microprocessors, which could help lower the energy costs of electronic devices.
Researchers have learned how to improve the performance of sensors that use tiny vibrating microcantilevers to detect chemical and biological agents for applications from national security to food processing. This improvement can be seen by measuring amplitude instead of frequency.
Most RFID tags that are to be used on metal objects are made by placing an antenna on a spacer. Such tags can be easily damaged because they stick out. New tags, developed by North Dakota State University researchers and being presented at an upcoming IEEE workshop, use the metal objects themselves as the antenna.
A research team led by investigators at Mayo Clinic in Florida has found that a small device worn on a patient's brow can be useful in monitoring blood oxygen in stroke patients in the hospital. Unlike a pulse oximeter, which also performs this task, the head patch uses near-infrared spectroscopy to quickly the presence of another stroke.
One day in 2010, Rutgers University physicist Vitaly Podzorov watched a store employee showcase a kitchen gadget that vacuum-seals food in plastic. The demo stuck with him. The simple concept—an airtight seal around pieces of food—just might apply to his research: Developing flexible electronics using lightweight organic semiconductors for products such as video displays or solar cells.
Kodak is at a crossroads: It could go the way of Circuit City, or it could prosper after bankruptcy like General Motors. Even in bankruptcy, the company boasts some enviable strengths, including a rich collection of photo patents, and more than $4 billion in annual sales. But it may be too late for a transition.
Although still two years away for consumers, the next generation of mobile technology will be up to 500 times faster than 3G smartphones. Approved this week at a United Nations radio communications meeting, the technology standard is called IMT-Advanced and will use the radio-frequency spectrum much more efficiently.
After a long decade of deliberation, United Nations member countries will cast their vote this week on an issue that lasts literally just a second. Leap seconds are necessary to prevent atomic clocks from speeding ahead of solar time, but the United States and other countries want to abolish it for all time.
In recent years nanoscale thermal analysis has been employed to reveal the temperature-dependent properties of soft polymers at the nanoscale. Researchers at the University of Illinois at Urbana-Champaign and Anasys Instruments, Inc. have now shown that they can perform this nanoscale thermal analysis on stiff materials like epoxies and filled composites.
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.
A University of California, Riverside team has made a breakthrough discovery with graphene, a material that could play a major role in keeping laptops and other electronic devices from overheating. The team has shown that the thermal properties of isotopically engineered graphene are far superior to those of graphene in its natural state.
