Electronic latch apparatus and method

摘要

A latch assembly, comprising a control element having a pivot point and an actuator. The actuator has a first position in which the control element is engaged by the actuator for pivotal movement about the pivot point and a second position in which the control element is disengaged by the actuator from pivotal movement about the pivot point. The latch assembly further includes a ratchet arranged and configured for rotation with the control element when the control element is engaged by the actuator and for non-rotation when the control element is disengaged by the actuator. A highly preferred embodiment of the invention includes an automatic unlocking circuit powered by a backup power source.
