EMC tests, which are a critical step in designing electrical and electronic products, recently have become a matter of concern due to the global increase in production of all types of E&E equipment, according to SGS Group. That rise has resulted in an increase in electromagnetic waves in the atmosphere that in turn led to authorities setting stricter EMC limits.Read more … [Read more...]
Electromagnetic Pulse Cannon Has Military’s Attention
A Canadian company will soon demonstrate an electromagnetic pulse cannon that is capable of stopping a car at a distance of 656 feet (200 meters). Flight International uncovered the story while following up on a recent U.S. Air Force request for an aircraft weapon capable of “disabling moving ground vehicles while minimizing harm to occupants.” Eureka Aerospace, which is being … [Read more...]
EMI Looms as Car Radio Booms
The growth of new technologies is raising consumer expectations for automotive entertainment, but the close proximity of electronic systems within the radio-head unit can cause interference and electromagnetic compatibility issues, says Harald Koch of Microtune Inc., in an article exploring the challenges of automotive radio design. This is especially true for sensitive analog … [Read more...]
Military Contractor Denies Selling Frequency-Hopping Technology
An Australian company has denied reports that its advanced 2050 mobile transceivers have been sold to the Myanmar military and are even capable of frequency hopping. The Australia-based Perth company has faced a barrage of criticism in Australian media that claim the radios have encryption-style frequency-hopping technology that makes it impossible for others to monitor the … [Read more...]
Train EMI Could be Affected by Federal Policy Change
Local officials are trying to determine how a recently proposed change in how the federal government evaluates transit projects for funding could affect Minnesota’s Central Corridor light rail project, as the Metropolitan Council and University of Minnesota continue to grapple over the impact of EMI on university labs and research facilities. Earlier this week, U.S. … [Read more...]
FCC Orders Wireless Entertainment Microphone Changes
The Federal Communications Commission issued an order Friday for Broadway theaters, sports franchises and other public entertainment forums to change the radio frequency they use for their wireless microphones. The F.C.C.’s ruling relates to a broader shift in the way the nation allocates precious spectrum used to transmit signals for mobile phones, TVs and other devices. The … [Read more...]

The plaintiff has actively opposed the proliferation of wireless systems in public buildings and claims he has been made homeless by his neighbor’s rejection of his requests. Read more from the Santa Fe New … [Read more...]
Interference Technology Teams Up with IEEE Product Safety Engineering Society
Interference Technology, the leading publication in the EMC industry, and the IEEE Product Safety Engineering Society announced today that they have agreed to allow PSES members and Interference Technology readers to post and answer questions and share information via the EMC-PSTC and Interference Technology forums. According to the new agreement, Interference Technology and … [Read more...]
Study: RFID Tags Could Effect Pacemakers
A new study published in the January issue of HeartRhythm Journal confirms that emissions from readers of ubiquitous radio frequency identification devices (RFIDs) can interfere with pacemakers, although that risk is small. The study examined the vulnerability to RFID reader electromagnetic interference in 15 pacemakers and 15 implanted cardioverter-defibrillators (ICDs), … [Read more...]
Motorcycle Cancer Risk Health Advocate Seeks Help
Health advocate Randall Dale Chipkar has asked California Governor Arnold Schwarzenegger to recognize International Motorcyclist Electromagnetic Safety Month. Extremely low frequency electromagnetic field (ELF EMF) radiation penetrating through motorcycle seats poses a health risk for riders, Chipkar says. Gov. Schwarzenegger’s health care reform program promotes prevention to … [Read more...]
