Power Outlet Analyzes Electrical Current Usage

Electrical interruptions, or “nuisance trips,” occur when a detector installed behind the wall trips an outlet's electrical circuit when it senses something that could be an arc-fault — a potentially dangerous spark in the electric line. The problem with today's arc-fault detectors is that...

Thermally Conductive Crystals Dissipate Electronics Heat

The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze, or shut down. To address this issue, researchers have optimized the crystal-growing process of boron arsenide — a material that has...

Microcontroller Altimeter (uCA)

Traditional altitude switch designs for harsh environments are mechanical in nature and operate by means of an inflatable bladder or bellows that mechanically depresses a pushbutton switch. The altitude trip point is set by mechanically adjusting the distance of the switch to the bellows. The mechanical action of...

Portable Brain Imaging System

Currently, concussion is measured by the symptoms someone experiences, but it is difficult to know what is happening in the brain in any one person. To address this problem, a portable brain imaging system was...

Researchers have observed waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice — a discovery that may dramatically...

An increase in computing performance has been achieved by squeezing ever more transistors into a tighter space on microchips. This downsizing has also meant packing the wiring within...
