  • Patent number: 7406846
    Abstract: An electronic lock incorporating one or more shape memory metal wire segment as its electromechanical transducer. An electronic control circuit injects electrical current into the shape memory metal wire, causing it to heat up and contract. A gate is positioned by the action of the shape memory metal wire(s) to either allow or block the movement of a locking bolt that affect locking or unlocking. Millions of operational cycles are achieved by limiting the stretching of the shape memory metal wire at low temperature to small percentages of its total length. The design lends itself to miniaturization, with commensurate reduction in power consumption, that is useful to the evolution of future electronic locks.

  • Patent number: 7387076
    Abstract: A locking system for a door of an enclosure has a handle, lock, and locking bolts mounted to the door, door jams mounted to the enclosure, dead bolts coupled to the locking bolts, and a blocking bolt coupled to the lock. When door is closed and handle is closed, then locking bolts are moved to locked position, such that door jams block path of locking bolts and thereby prevent door from being opened. When lock is unlocked, dead bolts can move toward each other allowing door to be opened. However, when lock is locked, door cannot be opened because blocking bolt, between dead bolts, prevents dead bolts from moving toward each other.

  • Patent number: 7325426
    Abstract: A safe electromagnetic lock including a first bolt provided with an elastic fastener, an elastic slide bolt positioned on an end of the first bolt, an electromagnetic device connected to a computer and a second bolt. The computer controls induction of the elastic fastener by the electromagnetic device, and a key inserted into a first keyhole, or another key inserted into a second keyhole, controls sliding movement of the elastic slide block to push against the elastic fastener, thereby releasing an abutting state and effecting unhindered unlocking of the safe electromagnetic lock. Upon unlocking, a front end of the second bolt extends out from a case, and protruding mount of the second bolt is used to press down on a steel ball, thereby enabling the second bolt to achieve a solid fixation and effectively preventing mistakenly locking and avoiding forgetting to lock the safe electromagnetic lock.
