New DARPA Technologies Could Make Cyber Warfare a Reality

Three years after the Defense Department named cyberspace a new domain of warfare, the Defense Advanced Research Projects Agency is unveiling technologies that could soon make it possible for military leaders and warriors to plan and execute real-time cyber missions in a territory charted so far only by machines.

Tiny Wireless Sensing Device Alerts Users to Telltale Vapors Remotely

A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at a variety of applications in military, commercial, environmental, healthcare and other areas.

Hypersensitive Graphene Sensor Could Detect Single Gas Molecule

University of Illinois at Chicago researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electronic properties that the researchers were able to exploit to increase sensitivity to absorbed gas molecules by 300 times.

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.

Low-Temperature-Compatible Electronics for a Miniature Nuclear Magnetic Resonance Spectrometer

The electronics have been demonstrated to function down to 77 K. NASA’s Jet Propulsion Laboratory, Pasadena, California Missions to Titan are severely limited in available mass and power because spacecraft have to travel over a billion miles to get there, consuming large masses of propellants. Thus low-mass, low-power instruments are a high priority need for Titan missions. A miniature, liquid-phase, high-resolution, pulsed proton-NMR (1H-NMR) spectrometer was developed with low mass (1.5 kg), requiring low power, that can be operated cryogenically on the surface of Titan. This work focuses on new pulsed electronic circuits, optimized for a nuclear magnetic resonance (NMR) spectrometer for analysis of hydrocarbon liquids on Titan.
