    Abstract: Method and apparatus for modulating the vibrations of an object with a constant amplitude has a sensor, e.g., a piezoelectric transducer, for sensing the vibrations. A light source, e.g., an LED, receives the sensed signal and illuminates a light dependent resistor (LRD). In turn, a control circuit controls the vibration amplitude in accordance with the LDR resistance. A full wave bridge rectifier can be used between the sensor and the LED.

    Abstract: A predetermined frequency and adjustable level excitation circuit for a capacitive load (B) having a first terminal connected to a reference voltage (G). The circuit includes two switches (S1, S2) connected in series between a supply voltage (Vcc) and the reference voltage (G). The junction (S) of the two switches is coupled to the second terminal (A) of the load. The two switches are not simultaneously closed. A circuit (10) periodically controls the closing of the switch connected to the supply voltage. A regulation circuit (R2, R3, 12) acts on the control circuit to trigger opening of one of the switches when the voltage across the load reaches a predetermined value.
