How Will NHTSA Test for Unintended Acceleration? The Engineering Way.

 

Members of Congress are generally lawyers and politicians, not engineers, but they are launching investigations and creating policies that have a direct impact on the designers and builders of incredibly complex vehicles, writes Washington Post columnist Frank Ahrens. One of the basic principles they should understand is that the only way to credibly figure out why something … [Read more...]

Light Rail May Force Relocation of Research Lab

 

The University of Minnesota is planning to move an underground nuclear magnetic resonance (NMR) research laboratory because the lab’s highly sensitive magnets are incompatible with the vibrations and electromagnetic interference that will be produced by a proposed light rail project. The university estimates it would cost $15 million to $20 million to move the lab, which would … [Read more...]

EMC Book Receives Scholarly Publishing Award

EMI Shielding Possible from European Nanomaterials Effort

 

European companies are taking part in a project to develop for the construction sector lighter structural materials, one of which is a polymeric nanocomposite reinforced with fibres and nanoparticles that offers a number of advantages over traditional materials, including shielding of electromagnetic interference. The material also offers flexibility in design, lightness, … [Read more...]

National Technical Systems Adds New Testing Facilities

 

National Technical Systems Inc. recently announced that it has opened a new engineering services and testing laboratory, in California to complement existing facilities and accommodate its expanding workload. Based in close proximity to the Silicon Valley in California, the lab offers a wide range of state-of-the-art testing equipment intended to add complementary services to … [Read more...]

FAA Backs Off of Pennsylvania Wind Farm EMI Claims

 

A portion of the 30 wind turbines at a planned wind farm in southwestern Pennsylvania would not pose an aviation hazard as initially feared, the Federal Aviation Administration said. Last year, the FAA said 15 of the 404-foot-tall turbines planned for Shaffer Mountain in Somerset County were too high to be safe or could create electromagnetic interference in nearby air … [Read more...]

Toyota Crisis Spotlights EMI Role in Auto Electronics, Hybrids

 

Investigations into sudden acceleration issues have put a spotlight on everything that can go wrong with automotive electronics. “Electromagnetic interference leaves no trace. It goes away just as it came,” says Michel Mardiguian, an engineer and consultant near Paris who worked with a European automaker on a gremlin-like electronic fault. Toyota is not alone in its troubles. … [Read more...]

Proposed Power Line Would Use Direct Current to Avoid EM Fields

 

An Ontario-based company has announced plans for a $3.8 billion, 355-mile transmission line that would link New York City and southern New England with Canadian hydroelectric and wind power sources. The line would be installed mostly under major bodies of water, including Lake Champlain, the Hudson River and Long Island Sound, and would pass the electricity using direct current … [Read more...]
