FAA Approves Greater Use of Portable Electronics in Flight
Airline passengers will be allowed to use portable electronic devices “during all phases of flight” if airlines determine their aircraft are not affected by interference, the Federal Aviation Administration said in a statement released today, adding that it expects the change will be implemented by the end of this year. The FAA’s decision was based on input from a panel … [Read more...]
Dolphins Inspire Radar System to Detect Hidden Electronics
Dolphins have inspired British researchers to create a new type of radar device that can detect hidden surveillance equipment and explosives and help locate buried avalanche or earthquake victims. According to New Scientist, the idea came to Timothy Leighton of the University of Southhampton’s Institute of Sound and Vibration Research while he was watching a nature show. After … [Read more...]
New Tunable Dielectric Material May Push Capacitor Performance
An international team of researchers based at Cornell University in Ithaca, N.Y. has announced the creation of a new tunable dielectric material—an insulator whose ability to store electrical charge changes when a voltage is applied—they say could benefit capacitor performance in smartphones and other electronic devices. “This is a radically different material compared to what … [Read more...]
Disney Walkie-Talkies Pick Up Crude Trucker Conversation
A Kent, Wash. family plans to file a complaint with the Federal Communications Commission after hearing a profanity-laced conversation between truck drivers over a pair of Disney Princess Royal Walkie-Talkies purchased for their nine-year-old child. "We picked up some things that she shouldn't be hearing, or any child should … [Read more...]
High Current Shielded Power Inductors Available in Low DCR and High Isat Versions
Magnetic component supplier Coilcraft’s new SER80xx series high current shielded power inductors are offered in two versions—one providing exceptionally low DC resistance and the other offering saturation current ratings up to 53 Amps—making them ideal for a broad range of applications. Designed for applications with high average current (up to 13 A rms), the low DCR version … [Read more...]
Researchers Achieve New Wireless Transmission World Record
Researchers in Germany have reportedly set a new world record for wireless data transmission using a combination of photonic and electronic technologies. In a successful experiment at the Karlsruhe Institute of Technology, researchers were able to transmit 100 Gbs of data per second at a frequency of 237.5 GHz over a distance of 20 meters. Previous attempts have yielded rates … [Read more...]
Technology Prevents Dropped Calls in Disaster Situations
A new solution created by a University of British Columbia graduate student could prevent dropped calls and text messages in disaster situations by using television and radio channels to transmit cellular signals when telecommunication systems are overloaded. Because wireless towers are designed to handle a specific amount of call volume, a sudden or drastic increase in the … [Read more...]
Scientists Harness Power of Lightning to Charge Mobile Phone
A collaborative effort between the University of Southhampton, UK and smartphone manufacturer Nokia has yielded new proof-of-concept research on harnessing the power of lightning to charge electronic devices. At the university’s Tony Davies High Voltage Laboratory—one of the world’s leading high voltage laboratories—researchers successfully used energy similar to that of a … [Read more...]
Interference-Cancelling Technology May Ease Spectrum Congestion
A small startup company is testing a new technology that may enable mobile devices to simultaneously transmit and receive data on a single frequency. Founded by a group of Stanford University researchers, who in 2011 developed the first wireless radios capable of sending and receiving signals at the same time, California-based Kumu Networks Inc. believes its new technology … [Read more...]
