Abstract: A security system (10) for providing a remote indication of a breach in security including an electronic device with an electronic device body (12) and a disabling member (14) couplable thereto. The electronic device is disabled by removing the disabling member (14). A security breach causes an alarm signal to be sent to the disabling member (14), which announces the receipt of an alarm signal. The electronic device can be a vehicle sound-reproduction device, and the disabling member (14) can be all or a portion of a face thereof. The alarm signal can be sent first by radio transmission that, if necessary, can be supplemented by a mobile communications transmission. The disabling member (14) could further act as a mobile communications pager and as a mobile telephone. The disabling member (14) could operate to affect operation of a vehicle in which the security system (10) is employed.

Abstract: A solenoid activated locking system primarily for hood and trunk manual release systems for vehicles. The solenoid is connected to a cable tied to the latch of a conventional hood or trunk release system. Unless activated, the solenoid prevents manual release of the trunk or hood lids to prevent access to the truck or engine compartment to someone who has obtained unauthorized access to the vehicle interior. The solenoid is automatically actuated for a preselected period of time whenever the ignition is turned on or off or when a reset switch is closed for more than a minimum and less than a maximum period of time. In addition, the solenoid is activated automatically during closure of the hood or trunk lid to permit secure engagement of the corresponding latch mechanism. An emergency release cable, hidden in an obscure location external of the vehicle, is provided for enabling manual release of the solenoid in the event of vehicle battery failure or other otherwise disabling event.

Abstract: A power window control for a motor vehicle provides express or one-touch movement in response to short activations of a control element and traditional power window movement during activation of the control element for longer periods. The control provides for automatic window closing with activation of a power door lock element, as long as the ignition is off unless the ignition key is in the ignition switch and the driver's door is open. This allows single touch vehicle locking but helps prevents the operator from locking himself out of the vehicle with the key still inside. Window movement, once initiated in the open or close direction, is stopped in response to motor stall when the open or closed limit is reached.

Abstract: A control means for a restraint belt retractor includes a latch bolt sensor directly actuating the disabling means of the retractor and movable between actuated and unactuated positions. The sensor is normally located in unactuated position in the path of movement of the latch bolt when the latch bolt is in latched position. As the latch bolt moves to unlatched position it engages the sensor and moves it to actuated position. The sensor is connected to an operating lever of the door latch through a lost motion connection. This connection provides an operative connection to the operating lever when the sensor is in the unactuated position and provides a free wheeling connection when the sensor is in an actuated position. This permits the inside and outside operators, which operate the operating lever, to be released and to free wheel relative to the sensor when the sensor is in actuated position.
