Methode Electronics, Inc. has released new medical grade shrinkMate™ heat-shrink tubing, which provides easy-to-apply shielding at the cable-to-connector joint, a common point of leakage. Made of clear medical grade polyester, the lightweight tubing shrinks when heat is applied to firm a conductive seal around an object, providing EMI, RFI and ESD shielding without the use of … [Read more...]
Marijuana-Growing Lights Interfere with Amateur Radio
The American Radio Relay League (ARRL), the national association for amateur radio, has filed a formal complaint against a certain type of lighting system used to cultivate marijuana after determining it interferes with MF and HF radio bands. The ARRL said that the ballasts in certain lighting devices like the Lumatek LK-1000, which are increasingly popular among marijuana … [Read more...]
Software Tackles Digitally Modulated RF Signals for Circuit and System Design
Agilent Technologies has announced the release of its new Genesys 2014 RF simulation and synthesis software. Designed for circuit and system designers, the Agilent EEsof EDA software features breakthrough modulated RF analysis as well as enhancements to its custom-filter direct synthesis technology. Using Genesys 2014, designers can now simulate digitally modulated RF signals … [Read more...]
EMC Evaluation and Analysis of Uninterrupted Power Supplies
Sulekh Chand and Nurul Hasan Electronics Regional Test Laboratory (North), New Dehli, India As computer usage increases, stable sources of AC power are a must. The computer needs a continuous 220 V AC source for its operation. In many parts of the world, the public utility supply is not stable, and disturbances and interruptions in power are frequent. To avert possible data … [Read more...]
Double-Duty Electrical Cables Can Store Energy
Scientists at the University of Central Florida have developed a way to both transmit and store electricity in a single lightweight copper wire. Jayan Thomas, a professor at the University of Central Florida, and Ph.D student Zenan Yu created a supercapacitor on the outside of a copper wire as a means to store energy while allowing electricity to continue passing through the … [Read more...]
Federal Regulators to Probe Chrysler Recall
Federal investigators are looking into a 2012 recall to fix airbag issues in over 700,000 sport utility vehicles following consumer claims of inadvertent airbag deployments in several vehicles said to be already fixed. The National Highway Traffic Safety Administration (NHTSA) said in documents filed on June 2 that it had opened a query into a 2012 recall for 744,822 Jeep … [Read more...]
Interference From Magnetic Light Rail Trains Forces UW to Move Labs
Sound Transit and the University of Washington are working out a $43 million deal to move some of the university’s labs across campus, in order to avoid interference caused by an underground light rail tunnel. The lab buildings in question contain very precise and sensitive equipment, such as electron microscopes, that are extremely vulnerable to electromagnetic interference. … [Read more...]
British Aristocrat Claims RF Interference in Drunk Driving Arrest
The recent court case of a British aristocrat with close ties to Princes William and Harry has once again highlighted the issue of breathalyzer radio frequency interference. Nightclub owner Guy Pelly was pulled over while driving his Audi R8 GT V10 Coupe through central London last May after reportedly visiting one of his exclusive clubs. The 32-year-old reportedly refused to … [Read more...]
New SPADs Maximize Precision While Minimizing Noise
Researchers at NIST’s Physical Measurement Laboratory have created a new, highly-efficient single-photon avalanche diode (SPAD) that is able to detect millions of photons per second while limiting noise. SPADs are detectors able to amplify the effect of one photon into a signal large enough to quantify and measure, amplifying miniscule electrical “hits” into an exponential … [Read more...]
Chip Cancels On-Channel RF Interference
Researchers at the University of Twente in the Netherlands have created a new chip designed to cancel on-channel interference using an adaptive beamforming technique. While the ability to make such a device has already existed for some time, the UTwente chip can be manufactured more cheaply and economically than any of its predecessors. The device, developed by postgraduate … [Read more...]
