DEFINITION

Classification: 73/862.626

Inductance or capacitance sensor:

(under subclass 862.625) Subject matter wherein the sensing means is responsive to either (a) the change of a property of an electrical circuit by which an electromotive force is induced in it by a variation of current either in the circuit itself or in a neighboring circuit, or (b) the change in a property of an electric nonconductor that permits the storage of energy as a result of the displacement when opposite surfaces of the nonconductor is maintained at a different potential.
