As German airline carrier Lufthansa announces its plans for new onboard WiFi and phone services starting on routes between the U.S. and Europe in the next few months, cell phone use on airplanes continues to be on hold in the United States, recent reports have indicated.Oregon Democrat Peter DeFazio is sponsoring a House bill called the Halting Airplane Noise to Give Us Peace … [Read more...]
FAA Reverses Decision on Wind Turbines over EMI Concerns
Less than a week after approving eight of 17 wind turbine locations without any restrictions at the Massachusetts Military Reservation, the Federal Aviation Administration has reversed its decision on five of the approved sites. The FAA now says those five locations at the Upper Cape base — all within the area used for military training and near the Falmouth town line — pose a … [Read more...]
Scientists Warn Again of 'Nuclear Threat' to Power Grids
The threat of attacks using electromagnetic devices gained attention again this week when scientists told the British Parliamentary Defence Select Committee that a nuclear warhead launched from a medium range missile and exploded 20 miles above the earth could cripple an entire country's power grid. The scientists warned that Iran and North Korea could produce a weapon capable … [Read more...]
New Light-Rail Proposal Could Lower EMI
A new proposal from the Maryland Transit Administration (MTA) could placate the University of Maryland’s concerns about the Purple Line light-rail system disrupting critical research equipment. University administrators fear the MTA’s preferred Campus Drive route for the light-rail line would lead to electromagnetic interference and vibrations from the trains rendering … [Read more...]
EMI from MP3 Player Headphones May Cause Hiccups in Cardiac Devices
Researchers are warning that patients with implantable cardioverter-defibrillators or pacemakers should avoid placing the headphones from their MP3 players too close to their chests. The researchers noted that, although the FDA concluded that electromagnetic interference from digital music players is unlikely to cause problems with implanted devices, there had been little known … [Read more...]
University Picks Building Site Because of Low EMI
University of Washington leaders recently broke ground on a molecular engineering building, the location of which was chosen partly because the natural vibration and electromagnetic interference are low at that site. Researchers will be making very sensitive measurements and any movement can interfere with the accuracy. The foundation will incorporate an extra-thick concrete … [Read more...]
Product Safety Compliance
Washington Laboratories will roll out the safety carpet with a two-day course on Product Safety Compliance October 13-14, 2009, in Gaithersburg, Md. The course will feature the latest information on design and verification of compliance for EN60950, EN 61010 and EN 60601. Attendees will perform hands-on measurements, construction reviews and product testing and learn critical … [Read more...]
Navy Seeks Ideas for Countering Directed Energy Weapons
The U.S. Office of Naval Research (ONR) in Arlington, Va., is interested in receiving research proposals on the best technologies for Counter Directed Energy Weapons (CDEW) to protect Navy and Marine Corps ships, submarines, aircraft, and other weapons from directed-energy weapons such as high-energy laser technology, non-lethal weapons like laser "dazzlers," high power … [Read more...]
Company Receives $23.3 Million NASA Contract
Government contractor ManTech International Corp. received a $23.3 million contract from NASA for engineering support services. Under terms of the deal, ManTech will provide to NASA's jet propulsion laboratory services such as circuit and systems reliability; simulation and analysis; electromagnetic compatibility; problem failure reporting and product and quality assurance for … [Read more...]
EMC Design, Troubleshooting and Pre-Compliance Testing
Because time-to-market and budget factors often drive many of today’s high-tech designs, electromagnetic compatibility (EMC) issues often surface at the last moment in the design cycle, potentially delaying product introductions. Very often, simple pre-compliance measurements and techniques can identify issues early when the cost of implementation is substantially lower and … [Read more...]
