Magnetic Chips Could Increase Computing’s Energy Efficiency

In a breakthrough for energy-efficient computing, UC Berkeley engineers have shown for the first time that magnetic chips can actually operate at the lowest fundamental energy dissipation theoretically possible under the laws of thermodynamics. This means that dramatic reductions in power consumption are possible — down to as little as one-millionth the amount of energy per operation used by transistors in modern computers.

Smartwatches Can Now Track Your Finger in Mid-Air using sonar

As mobile and wearable devices such as smartwatches grow smaller, it gets tougher for people to interact with screens the size of a matchbook. That could change with a new sonar technology developed by University of Washington computer scientists and electrical engineers that allows you to interact with mobile devices by writing or gesturing on any nearby surface — a tabletop, a sheet of paper or even in mid-air.

1U CPU Cooler

Specifically designed for use with data storage, high-density, backup, or cloud servers, Jaro's (Boca Raton, FL) new low-profile, 1U CPU cooler (with heat-sink) is perfect for Intel processors that interact with square socket (2011) types. The high-quality coolers come in two sizes, one of which provides a narrow heat-sink solution. Both are popular in small space applications. This new (dual bearing) CPU cooler & heat-sink combination is enhanced by skived, copper fins. As each copper fin is individually attached to the heat-sink, it is able to provide evenly-distributed levels of cooling. The 1U boasts an impressive 70,000 hours of long life, at 40 DegC / 65%.

Panel-Mount Connectors

TE Connectivity Ltd. (TE) (Harrisburg, PA) has launched its DEUTSCH 369 series panel-mount connectors. The new panel-mount connectors have the ability to mount in seconds, suit multiple panel thicknesses, accept the use of standard 369 wire strain-relief backshell and require no fasteners, featuring an anti-rattle panel gasket. The product’s rectangular shape permits space-efficient stacking and remains fully compatible with the standard 369 series connectors. The electrical interfaces are fully sealed for use in areas with high levels of moisture, using cork-in-bottle and triple wire seal technology.

Reduced-Cost, Chirped Pulse, Fourier Transform Microwave (CP-FTMW) Spectrometer Using Direct Digital Synthesis

This technology could be used to further extend the bandwidth of the instrument.

Goddard Space Flight Center, Greenbelt, Maryland

Microwave spectroscopy is an invaluable tool for studying the structure, dynamics, and even the handedness of gas phase species. In particular, the specificity of microwave spectroscopy has been central to the unambiguous identification of the great majority of molecules detected in the interstellar medium. Applications of microwave techniques to problems in physical chemistry and molecular astrophysics have been greatly accelerated by developments in laboratory techniques.
