Utilities operating nuclear power plants have been dealing with electromagnetic interference (EMI) problems for over two decades. Many early problems that affected the operation of instrumentation and control (I&C) equipment in plants stemmed from the use of wireless transmission devices (WTDs) (e.g., radio walkie-talkies, cellular phones, etc) inside the plant in the … [Read more...]

Wireless Medical Device Swims Through Blood
Ada Poon of Stanford University demonstrated a tiny, wirelessly powered, self-propelled medical device capable of controlled motion through a fluid – blood, to be exact. The era of swallow-the-surgeon medical care may no longer be the stuff of science fiction. Poon is developing a new class of medical devices that can be implanted or injected into the human body and powered … [Read more...]
Company Expands Presence in the Medical Diagnostic X-ray Marketplace

Onanon's "breadboard" automated manufacturing methods have cost effectively produced connectors with low-profile integrated devices in applications as diverse as medical devices and military avionics, giving engineers the power to design greater functionality than … [Read more...]
Experimental Magnetic Pulses May Help Heal A Brain After Stroke
Recent testing has found that placing electromagnetic coils against the scalp stimulates brain cells to “form new connections, allowing the brain to rewire itself to compensate for damage caused by a stroke.” In Italy, researchers looked at patients with hemispatial neglect, a common problem with stroke victims where they are “unable to see or recognize anything on one side of … [Read more...]
Tests Help Ensure Reliable Wireless Alarm Beacons for First Responders
Tests at the National Institute of Standards and Technology (NIST) are helping to ensure that alarm beacons for firefighters and other emergency responders will operate reliably in the presence of other wireless devices.PASS devices sense movement and activate an alarm if a firefighter remains motionless for too long. Newer Personal Alert Safety Systems (PASS) systems also have … [Read more...]
Electromagnetic Fields Control Tumor Growth
New evidence by University of Alabama at Birmingham researchers that specific electromagnetic fields can safely block the proliferation of cancer cells and tumor growth may help refine a new, targeted therapy without any collateral damage.Very low levels of amplitude-modulated radiofrequency electromagnetic fields block cancer-cell growth in a tumor- and tissue-specific … [Read more...]
Electromagnetic Compatibility Requirements for Household Appliances
CISPR 14-1:2005+A1:2008+A2:2011 applies to the conduction and the radiation of radio-frequency disturbances from appliances whose main functions are performed by motors and switching or regulating devices, unless the R.F. energy is intentionally generated or intended for illumination. It includes such equipment as: - household electrical appliances, - electric tools, - … [Read more...]
