Abstract: An oscillatory circuit, operating in the ultrasonic or high sonic frequencies, generates power for a piezo-electric transducer in proportion to mechanical resistances or loadings encountered by the transducer. High sensitivity and instantaneous power adjustment to a wide variety of loads is obtained, and instant ''''turn-on'''' and ''''turn-off'''' at the adjusted power settings are secured, by a circuit in which the input to the first stage of a two-stage oscillatory circuit comprises the sum of three feedback components plus a DC forward bias.
