Abstract

See full text

A circuit arrangement for use in a utility meter includes a mechanical switch, a processor device, and a latch circuit. The mechanical switch has a closed position and an open position, and is supported by a meter housing. The mechanical switch is operably coupled to generate a close signal when the mechanical switch is in the closed position. The processor device has a first processor input and a second processor input. The first processor input is operably coupled to receive the close signal. The latch circuit is operably coupled to receive the close signal and generate a latched signal responsive thereto. The latch circuit is configured to latch the latched signal for a predetermined time, the predetermined time corresponding to a wake-up time of the processor device. The latch circuit is operably coupled to provide the latched signal to the second processor input.
