Scientists from the University of Bristol and the University of the West of England (UWE Bristol) have improved the performance of a pair of musical Wi-Fi gloves worn by popstar Imogen Heap. Used during Heap’s experimental live music performances to control both music and visuals with a series of gestures, the so-called Mi.Mu glove system must be robust enough to cope with … [Read more...]
Avoid the Most Common Failures with These 7 Essential EMC Design Rules
A reader recently asked me what the top design rules were that they could implement on their product to maximize the chances of passing FCC and CE testing. There’s no doubt that there are countless ways to fail emissions and immunity tests, but a pattern of failure modes did emerge at my EMC lab.Regardless of the type of product I was testing, be it medical, industrial, … [Read more...]
Beam-Switching Antenna Compensates for Aircraft Movement
A software-defined, electronically-reconfigurable antenna technology developed by researchers at the Georgia Institute of Technology has now been tested on land, in the air and on the ocean. U.S. Department of Defense representatives attended an event earlier this year in which the capabilities of Georgia Tech’s Agile Aperture Antenna (A3), which can change beam directions in … [Read more...]
