Piezoelectric Resonator with Two Layers

Microelectromechanical systems (MEMS) filters have advantages in being able to reduce the size, weight, and power required when used as part of electronic systems such as radios; however, MEMS-type filters have limitations. For example, thickness MEMS-type filters (e.g., thickness-extensional mode...

Evaluating Effects of Exhaust Heat Recovery Systems on Fuel Economy and Emissions

The exhaust heat recovery system (EHRS) in an automobile captures the thermal energy from exhaust and transfers it to the engine coolant. As the car warms up,...

Power Line Detection System for Unmanned Aircraft Systems

Electrical power lines pose a serious crash hazard to helicopters and other air-based vehicles, especially small aerial vehicles such as unmanned aircraft systems (UAS). This is because power lines are so widespread, hard to see, and strung at roughly the same height above the ground at...

Switch Controls Light on a Nanoscale for Faster Information Processing

Photons, or units of light, are faster than electrons and could, therefore, process information faster from smaller chip structures. A switch was designed that bypasses a...

“Soft Hardware” Cloth Has Built-In Electronic Devices

Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened...
