As you may have guessed, this kind of detector works by detecting an inductance change in a wire loop (aka coil) buried in the road. Having a car pass several inches on top of it produces such an ...

They’re normally made of a single turn of wire in a loop of diameter well below half a wavelength, and, in their transmitting versions, they are often tuned to resonance by an air-spaced ...

Abnormal areas of tissue are removed using a thin, wire loop that works like a scalpel. An electric current is passed through the loop as it removes the abnormal tissue, cauterizing the blood vessels ...

The fundamental concept to understand about two-wire technology is that devices using it are powered by and communicate with the same two wires in a loop. This is why two-wire technology is often ...
