A system and method for adjusting the frequency of operation of a radio frequency circuit including an inductive loop having an adjustable exposed inductor portion is provided. The frequency of operation of the circuit is first detected with means for detecting a parameter relating to and representing the frequency of operation. The adjustable inductor portion is associated with a selectively movable actuator device coupled to the frequency detecting means and a source of signals representing a predetermined frequency of operation for the circuit. A control circuit means, preferably a computer, is coupled to the detecting means and to the source of signals to provide an output control signal when the detected frequency of operation bears a predetermined relationship to the predetermined frequency of operation. The control signal operates the actuator device to adjust the configuration of the exposed inductor portion by moving the actuator device whereby the inductance of the inductive loop and the frequency of operation are associatively varied. The configuration of the inductor portion is fixed at a position of adjustment determining the frequency of operation to be at the predetermined frequency.

Radio circuit tuned by adjustably deforming an inductance coil

A piezoelectric assembly with a flexible circuit interconnect is provided. The flexible circuit interconnect is comprised of a first flexible insulating base film including spaced electrically conductive circuit traces, a second flexible insulating film disposed over a portion of the first base film and a segment of the traces, and means for electrically connecting the traces to an electrical circuit. Also provided is a method for manufacturing a flexible circuit interconnect for a piezoelectric element comprising laminating spaced circuit traces on a flexible insulating base material to define a contact arrangement with a first set of terminal ends of the traces; attaching termination electrical connectors at a second set of terminal ends of the traces; mounting an insulating overlay to the base material for insulating a portion of the traces and electrical connectors; and, mounting a piezoelectric element to the contact arrangement.
