Self-Powered Intelligent Keyboard Could Provide Additional Security

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.

Automotive Circuit Protection Using High-Reliability TVS Diodes

Diode technology eliminates transient surges and enhances vehicle safety. Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards. The three major sources of electrical hazards in automotive systems are electrostatic discharge (ESD), switching loads in power electronics circuits, and lightning. Overcoming these transient surges that can harm the vehicle’s electronics, whether under the hood or in the cabin, is one of the biggest obstacles of system design.

A Resistive, High-Voltage, Differential Input Interface in a 3.3-V BiCMOS 0.5-μm Process for Extreme Environments

NASA’s Jet Propulsion Laboratory, Pasadena, California Wide-temperature and extreme-environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme-environment electronics, by their inherent nature, allow operation next to sensors in the ambient environment, reducing noise and improving precision over the warm-box-based systems employed today.

Aircraft with Hybrid Engine Can Recharge in Flight

Researchers from the University of Cambridge, in association with Boeing, have successfully tested the first aircraft to be powered by a parallel hybrid-electric propulsion system, where an electric motor and gas engine work together to drive the propeller. The demonstrator aircraft uses up to 30% less fuel than a comparable plane with a gas-only engine. The aircraft is also able to recharge its batteries in flight, the first time this has been achieved.
