Patent ID: 7107848

Claim:
Apparatus for adjusting an operational parameter that varies with temperature changes, said apparatus comprising: a first torsional hinged device that oscillates at a resonant frequency, said resonant frequency varying with the temperature; a sensor for monitoring and for providing a signal representative of a selected parameter of said oscillating device; a drive mechanism for providing motion to the first torsional hinged device and for receiving said signal representative of said selected parameter of the torsional hinged device to determine changes in said resonant frequency and to provide an output signal indicative thereof; a component having a parameter that drifts with temperature and has an input connection for receiving an input signal that adjusts said drifting parameter; and a feedback circuit connected to said input of said component for providing said signal indicative of changes in the resonant frequency of said torsional hinged device as said input signal to adjust said component so as to compensate for said drift due to temperature changes.
