Wireless Sensing Lets Users “Train” Smartphones for Gesture Control

University of Washington researchers have developed a new form of low-power wireless sensing technology that could soon let users “train” their smartphones to recognize and respond to specific hand gestures near the phone. The “SideSwipe” technology uses the phone’s wireless transmissions to sense nearby gestures, so it works when a device is out of sight in a pocket or bag and could easily be built into future smartphones and tablets.

NASA Launch Pads Protected Against Lightning-Induced Power Surges

Circuit protection components Littelfuse Chicago, IL 773-628-1000 www.littelfuse.com Circuit protection is an essential part of any electrical or electronic product or system design. As the complexity of the product or system grows, circuit protection design becomes increasingly crucial. As circuitry is increasingly miniaturized, it’s more important than ever to protect it from damaging power surges. For engineers whose work is critical to the safety of a NASA mission, protecting the lives of crewmembers depends to no small extent on protecting delicate digital circuitry from hazards like electrostatic discharges and lightning-induced surges.

Fourier Transform Spectrometer on Autonomous Self-Healing Hardware Platform

This liquid crystal waveguide-based platform provides self-healing for electronics in dangerous or hard-to-reach locations. NASA’s Jet Propulsion Laboratory, Pasadena, California The autonomous self-healing (eDNA) hardware platform is a reconfigurable field-programmable gate-array (FPGA)-type platform developed by Technical University of Denmark (patent: WO/2010/060923). It is capable of autonomously reconfiguring itself in case a fault is detected and, thusly, restoring functionality at a fault-free location on the chip.
