  • Patent number: 6100802
    Abstract: An alarmed cable lock that sounds an alarm upon an attempt to open the lock or remove the secured item while the alarm is armed. The invention includes a lock, a cable, a power source and an alarm. The lock includes a C-channel closed at one end, a switch, and a blocking pin. The cable is attached at one end to the lock. The free end of the cable terminates in a head that is formed to slide in the C-channel. The switch is exposed in the C-channel. When the lock is armed, the blocking pin extends into the C-channel to prevent the free end of the cable from sliding out of the open C-channel end. If an attempt is made to remove the end of the cable by sliding it out the C-channel, the head passes by the switch and sets off the alarm. The alarm/lock features are operated by remote control.

  • Patent number: 5999095
    Abstract: An access control unit for an electrified door lock also toggles the state of an associated alarm. The unit is arranged to unlock the door only temporarily, but the alarm state is not toggled except by user request. The system is arranged to prevent the anomalous situation of an unlocked door and an armed alarm. Another aspect is the use of standardized key-receiving nests in disparate types of access control devices. Some disparate devices employ identical key-receiving nests, while others use different forms of nests. Yet all mate with and respond to a single type of key.

  • Patent number: 4969343
    Abstract: A lock mechanism for an emergency exit door or the like is constructed with a tongue pivotable between two positions--an extended position and a retracted position, the former for use when the door is closed and locked, and the latter when the door is open--and a pawl arranged for releasably retaining the tongue in either or both of the two positions, the tongue being releasable from the pawl by depressing a breakable seal or by a cylinder key. The mechanism has the advantage of being readily releasable from the inside yet capable of being sealed against unauthorized use.

  • Patent number: 4855710
    Abstract: In a burglarproof system for an automotive vehicle, a door key cylinder arranged at a vehicle door includes a cylindrical body and a rotor accommodated therein. An acting section provided at the rotor extends radially from an axis thereof. A door key switch arranged in the vicinity of the door key cylinder detects the acting section to output a key-operation detection signal, when the rotor is angularly moved by turning operation of a key to bring a door locking mechanism to an unlocked position. A door lock switch detects in which one of the locked and unlocked positions the locking mechanism is. A stealing detector is provided for outputting a stealing detection signal when the stealing detector does not receive the key-operation detection signal from the door key switch, but receives the lock-releasing detection signal from the door lock switch. A burglarproof unit executes operation for a burglarproof in response to the stealing detection signal.
