Astronomers have identified 27 potential new planets orbiting binary star systems, more than doubling ...

Researchers at the Georgia Institute of Technology have created a passive motion/contact sensor that detects motion using ...

But, similar bursts from other sensors in close proximity may interfere with the echo timing. When that happens, the sensors suffer from a condition called cross talk. Interference from cross talk ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
