For the past nine months, Google has been priming the public for the launch of Google Glass, a head-mounted, Internet-enabled display that—if you buy the hype—will revolutionize computing and totally rock your world.

A marketing blitz featured skydivers sporting Glass as they plummeted to Earth and runway models doing their best to strike a modish pose with the smart glasses perched on their noses. A YouTube video promoting the new specs tailed a man as he woke up, ate breakfast, went to a bookstore, met a friend, and shared a sunset with his girlfriend, all while receiving a stream of messages and augmented information about his surroundings on his Google Glass display.

Janet Barth spent most of her career at the Goddard Space Flight Center, in Greenbelt, Md.—which put her in the middle of some of NASA’s most exciting projects of the past 40 years.

She joined the center as a co-op student and retired in 2014 as chief of its electrical engineering division. She had a hand in Hubble Space Telescope servicing missions, launching the Lunar Reconnaissance Orbiter and the Magnetospheric Multiscale mission, and developing the James Webb Space Telescope.

A Diamond "Blanket" Can Cool the Transistors Needed for 6G

Gallium nitride transistors have struggled to handle the thermal load of high-frequency electronics

High-power radio-frequency electronics are a hot commodity, both figuratively and literally. The transistors needed to amplify 5G and future 6G signals are struggling to handle the thermal load, causing a bottleneck in development. Engineers in the United States and England have teamed up to demonstrate a promising solution—swaddling individual transistors in a blanket of thermally conductive diamond to keep them cool.

“Thermal issues are currently one of the biggest bottlenecks that are plaguing any kind of microelectronics,” says team lead Srabanti Chowdhury, professor of electrical engineering at Stanford University. “We asked ourselves ‘can we perform device cooling at the very material level without paying a penalty in electrical performance?’”

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
