Abstract
The charge on a capacitor is supplied by a manual generator in a self-powered lock. The capacitor retains a reduced level charge after completion of the operation of the electronic lock controls that may serve as a capacitor pre-charge. The pre-charge reduces the amount of manual input to the generator required. The drain of the electronic control circuitry on the capacitor is disconnected responsive to a microprocessor command at the completion of microprocessor operations. The disconnection may occur at a higher level of charge voltage on the capacitor when the control is from the microprocessor without having to wait for charge decay to reach a disconnect or power down level based on charge voltage level.
