The circuit was designed to detect and identify audible sound signals within the boundary limits of the device. Sound may be termed as a fluctuation or alternation in pressure, stress, particle ...

Imagine being able to hear people whispering in the next room, while the raucous party in your own room is inaudible to the whisperers. Yale researchers have found a way to do just that—make sound ...

An “Infinite Impedance Detector” might sound a little like something that [Zaphod Beeblebrox] would use to zip around the galaxy. It’s not, of course, but it is an interesting and useful demodulator ...

One of the biggest hurdles for smart home devices is convincing users they need them in their home. They need to offer some sort of tangible benefit to a traditionally low-tech option. A smoke alarm ...

Photonic quantum technologies hold promise to repeat the success of integrated nanophotonic circuits in non-classical applications. Using linear optical elements, quantum optical computations can be ...
