Artificial “Blubber” Protects Divers in Frigid Water

When Navy SEALs carry out dives in Arctic waters, or when rescue teams are diving under ice-covered rivers or ponds, the survival time even in the best wetsuits is very limited — as...

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...
