Remote-control garage door openers near the Blue Grass Army Depot in Richmond K.Y. may stop working due to military radio systems switching to a new frequency range. The U.S. military will switch all land mobile radios (LMRs) to new frequencies, which are also the same frequencies used by certain unlicensed consumer devices, like garage door openers. These frequencies have … [Read more...]
Radio Interference May Cause Malfunction in Amtrak’s New Anti-crash System
Amtrak is working on an anti-crash system to prevent high-speed derailments, like the fatal derailment in Philadelphia P.A. last month that killed eight passengers, injured hundreds and caused more than $9.2 million worth of damages. However, the anti-crash system may malfunction near freight railroads. Radio interference from freight rails may disable Amtrak’s anti-crash … [Read more...]
NASA Developing Early Warning System for Solar Flares
NASA has announced it is developing an early warning system for solar flares to give the Earth more time to prepare for storms, thus reducing damage. Scientists from both NASA’s Goddard Space Flight Center and Imperial College London published their research and experiments in Space Weather in the June 9 edition. Their research demonstrates how the new warning system can both … [Read more...]
Fluid Operated Computer uses Electromagnetic Fields to Perform Operations
A group of engineers from Stanford University have produced the first ever water operated computer. The computer uses electromagnetic fields to pump water droplets impregnated with magnetic nanoparticles into gates to perform complex logical operations. Manu Prakash, a Stanford assistant professor, spent almost an entire decade thinking about the possibility of a … [Read more...]
Expanded Line of Solid State Amplifiers Makes Debut
Pasternack introduces a new line of 22 solid state high power amplifiers that cover UHF, VHF, L, S and C Frequency Bands. These amplifiers can produce more than 10 watts of power in frequencies from 150 kHz to 7500 MHz. “All of the high power amplifiers in this product family have single voltage supplies which are internally regulated and the circuits are enclosed in … [Read more...]
China’s Railway System Receives ‘Smart Station’ Upgrade
Ruckus Wireless, Inc. has partnered with Smartac Group China Holdings Limited (Smartac) to help build smart Wi-Fi networks for China’s railway system. Networks are currently being developed in more than 300 railway stations in Beijing, Guangzhou and Lanzhou. The goal of the project is to offer all railway passengers high-performance Wi-Fi and to upgrade China’s railway system. … [Read more...]
Multilayer Power Inductors Offer Narrow Inductance
TDK Corporation has expanded its multilayer power inductor portfolio with the introduction of the new MLJ1608 high-performance series. The MLJ1608 series was specifically designed for use in near field communication (NFC) and power line applications. The inductors are best suited for filtering between the antenna and control chip in NFC applications. Beside NFC modules, the … [Read more...]

This filter line is best suited for noise reduction on DC power lines in automobiles, communication equipment, electronic equipment, medical equipment and many other applications. The filters offer high attenuation, low … [Read more...]
Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
Breakthrough in Electromagnetism to Improve Global Communication
Researchers from the University of Cambridge in England have announced an electromagnetic breakthrough – the production of an antenna so small that it can be incorporated into electronic chips. They realized electromagnetic waves are not only generated from acceleration of electronics, but also from symmetry breaking. “Symmetry breaking in physics describes a phenomenon where … [Read more...]
