Abstract
There is described a self-powered lock system for a movable member coupled to a lock mechanism having a first state in which the movable member is locked and a second state in which the movable member is unlocked. The system comprises an electrical energy storage device having an electrical charge stored therein, a control unit for controlling the lock mechanism, a trigger unit for triggering an unlocking of the lock mechanism, and a passive detection unit for detecting an activation of the trigger unit. Upon detection of the activation, a conductive path is provided between the control unit and the storage device for powering the control unit with the charge stored in the storage device. The lock mechanism is in turn unlocked by the control unit. A generator coupled to the storage device may then generate electrical energy and store the generated energy in the storage device for future use.
