Abstract
A dual solenoid-based linear motion actuator has a single input for supplying both electrical power and positioning signals for a pair of solenoid coils. A binary control signal alternates between first and second voltage levels, one of which is used for powering the dual solenoid actuator and its control electronics, and also for controllably displacing a movable element to a first of a pair of spaced apart positions terminated by electrically conductive stops. The moveable element is electrically coupled to the second voltage level so that contact with either of the stops will apply the second electrical voltage level to control logic circuitry. The actuator's input terminal is coupled to an electrical energy storage circuit, such as a battery and/or capacitor in parallel with the battery, that serves as the power supply for the actuator, extracting and storing power necessary for operating the control circuitry and energizing the solenoid coils.
