A new approach for transmitting power wirelessly to electric automobiles could bring the development of highway stations capable of powering fast-moving vehicles closer to reality. Researchers at North Carolina State University have developed new techniques for transferring power to moving electric vehicles that improves on previous methods. The team designed a series of … [Read more...]
RF Conformance Test System for Vehicle-to-Vehicle Applications
Rohde & Schwarz has introduced the new R&S TS-ITS100, the world’s first fully automated test system for standard-compliant testing of RF components for vehicle-to-vehicle communications and intelligent transport systems (ITS) in line with IEEE 802.11p. With its compact size, the RF conformance test system can be used throughout the entire value chain, from R&D to … [Read more...]
Study Highlights Need to Re-Evaluate Railway EMC Standards
As part of a recently-completed European Union study on the effects of multi-source electromagnetic interference on trains, a British consulting company has helped redesign the way that conformance to railway electromagnetic compatibility (EMC) standards is determined. The project in question, a two-year study known as TREND (Test of Rolling Stock Electromagnetic Compatibility … [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...]

Study Finds No Danger from Magnetic Fields in Electric Vehicles
An international study has concluded the electromagnetic radiation produced by the electric motors powering hybrid, plug-in hybrid, all-electric and hydrogen fuel cell cars to be harmless to passengers inside the vehicles. The EU-funded study, led by Norwegian independent research organization SINTEF, looked at the intensity of magnetic fields in seven electric cars, one … [Read more...]
EMI Shielding Compounds for Automotive Radar and Sensing System Components
Thermoplastics compounder RTP Company has developed new EMI shielding compounds ideal for replacing metal or conductive coated plastic housings in automotive sensing systems. Automotive radar and sensing systems designed to maintain vehicle safety and reliability require EMI protection to eliminate “noise” that could interfere with signal processing, the company says. As the … [Read more...]
Software for Installed Antenna Analysis Receives Update
Delcross Technologies has announced version 4.0 release of its Savant software for modeling the installed performance of antennas on electrically large vehicles. New features in this release of Savant include multi-bounce edge-diffraction rays that improve accuracy by modeling antenna interactions with shadowed portions of the platform, an integrated workflow with CST STUDIO … [Read more...]
