Abstract: An electromechanical transducer assembly is disclosed wherein a transducer member, for example a piezoelectric crystal, is utilized to convert a mechanical input thereto to an electrical output. An amplifier circuit including an active element, such as a field effect transistor of the metal oxide silicon type, is disposed on the member to receive the electrical output and to increase its power gain. An elastomer is disposed over the entire circuit and the member to encapsulate the entire circuit and prevent low-impedance paths from developing in and about the circuit. The elastomer is selected to have such an elasticity to permit the member to be highly sensitive to the mechanical input thereto.

Abstract: An ultrasonic object detector system operating on the echoranging principle and including circuit adjustments which render the object detector system responsive to objects at a preselected distance. Additional circuit adjustments provide control of the depth of field sensitivity of the object detector system relative to the selected object distance as well as providing the capability of ''''locking-in'''' the object to prevent loss of object recognition.
