A reprogrammable integrated circuit including overwritable nonvolatile storage cells. A received signal is amplified by amplifier circuitry, the gain of which is controllably adjusted by the microcontroller based upon the outputs of threshold detectors and power level measurement circuitry that monitor the amplified received signal. The separated o-tolylacetic acid salt is converted to o-tolylacetic acid by controlled acidification and the o-tolylacetic acid is extracted for re-use. A faster reaction time is provided, yet without increasing the number of turns of the trip coil winding, and provides a more efficient actuator. The synchronization lock and write lock are maintained until their respective leases expire.
