Abstract
An activation apparatus is provided for motion-based activation of a voltage regulator. Also provided is a method of activating a voltage regulator in a motion-based manner. A motion-responsive element detects motion (e.g., motion, vibration, and/or acceleration) and applies an activation signal to the voltage regulator in response thereto. The voltage regulator becomes activated in response to this signal. Also provided is a charging system containing a voltage regulator that is activated based on motion. Since some voltage regulation units require strobing of the activation signal, the activation apparatus can be provided with strobing circuitry. The strobing circuitry turns the activation signal ON and OFF in a cyclic manner, preferably over for a predetermined duration, according to the needs of the particular voltage regulation unit or a transistor associated therewith that controls the flow of current through a field winding of the charging system's generator.
