Patent number: 5805054Abstract: An automobile theft prevention system including a bistable switching device that receives a voltage input, delivers and controls a voltage output to drive an essential electrical circuit in the engine electrical system of an automobile. The system has circuitry coupled with the switches of the standard door switch circuit installed on automobiles associated with interior lighting. When a door is opened, circuitry of the system will be actuated thereby, to sequentially activate visible alarm devices, electrically shut down the engine and activate audible alarms. Entering a coded signal before opening a door prevents shutting down of the engine. When the engine shuts down by opening a door or by depressing a panic button on a code impulse device, it requires the entry of a coded signal to be restarted, as well as to turn off the visible and audible alarms.Type: GrantFiled: May 17, 1993Date of Patent: September 8, 1998Inventor: Merrill Baxter

Patent number: 5774043Abstract: When an ignition switch detects that a key rotor of an ignition key cylinder has been turned to the accessory position by a key, a controller energizes a primary coil to cause it to output a high-frequency signal. In the key, a secondary battery is charged with a constant DC voltage generated from an AC voltage induced across a secondary coil. A transmission circuit is powered by the secondary battery, and allowed by a timer circuit to transmit a radio signal including an identification code during a predetermined period after the high-frequency signal is received by the key. Alternatively, the controller energizes the primary coil plural times with a cycle consisting of predetermined output and pause periods if the transmitted identification code does not coincide with a preset identification code at the first comparing attempt.Type: GrantFiled: August 29, 1994Date of Patent: June 30, 1998Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Yoshiyuki Mizuno, Sadao Kokubu, Hisashi Aoki, Takashi Mizuno

Patent number: 5757269Abstract: A closure latch or bolt monitoring device having a housing mountable in a closure frame which housing receives a latch or bolt. A pivotal rocker plate is normally biased to a rest position in which a flange portion of the rocker engages a switch connectable to an alarm system. When a latch or bolt is extended into the housing, the rocker plate is pivoted causing it to disengage from the switch providing an indication to the alarm system that the bolt or latch is properly engaged in the closure. An alternate embodiment allows separate monitoring of two lock components such as a separate bolt and latch.Type: GrantFiled: December 11, 1996Date of Patent: May 26, 1998Assignee: Securitron Magnalock Corp.Inventors: Thomas E.

Patent number: 5752728Abstract: An alarm-triggering locking mechanism for the lock and/or hinge area of a door to be secured or a window to be secured is proposed, which is embodied as a locking plate (23) which can be attached to a door or window frame by means of holding screws (27) embodied as the first blocking device. A second blocking device, which is harder to overcome by the effect of force, is embodied as at least one striker element (25) rigidly connected with the locking plate (23) and which, following the limited movement of the locking plate (23) in the opening direction, comes to rest against a counter-striker element (26) anchored on the door or window frame. An alarm, in particular a silent alarm, is triggered via radio or the telephone net after the first blocking device has been overcome. The burglar is thereafter delayed by the second blocking device, which makes it possible for security forces to reach the location of the break-in and to arrest the burglar while the break-in is still in progress.Type: GrantFiled: August 12, 1996Date of Patent: May 19, 1998Inventor: Erich Matouschek

Patent number: 5754107Abstract: In an apparatus and method for deterring and preventing forced entry intrusion into residential and commercial premises, the apparatus is a combination vertically operated dead bolt door lock surrounded by an alarm housing having battery means, a loud speaker, and a contact switch. The lock striker plate is mounted to the door frame as usual, but the lock is not mounted to the door at all, but rather is attached in suspension within the alarm housing. The alarm housing is attached to the door, and the lock within the housing is offset so as to float in spaced-apart relationship from the door on which the alarm housing is installed. Upon an intrusion effort, the door, together with the alarm housing will be shoved inward toward the premises by the intruder. But the lock floating within the alarm housing will be restrained by its engagement with the striker plate mounted to the door frame.Type: GrantFiled: February 18, 1997Date of Patent: May 19, 1998Inventor: Salvatore Ferrantelli
