Abstract: The security system provides an aircraft security system capable of protecting both single and multiple engine aircraft. Variations of the present system prevent unauthorized starting of protected aircraft and activate an alarm when engine starting it is attempted. Embodiments of the system draw no power from the aircraft when the security system is armed and in no way interferes with the normal starting or operation of the aircraft when the system is disarmed. Embodiments of the present system can activate an alarm when an aircraft's doors or panels are opened. Embodiments of the present invention can activate an alarm when installed equipment or other devices are tampered with or removed from their housings.

Abstract: When a driver of a vehicle issues a command to stop an engine, an in-vehicle unit communicates with a portable device. When collation of ID codes of the in-vehicle unit and the portable device is OK, a collation ECU permits stopping of the engine. When the result of ID-code collation is NG, the ECU prohibits stopping of the engine. When a vehicle passenger has taken out the portable device from a vehicle compartment, once the engine of the vehicle is stopped, the engine can no longer be restarted. By prohibiting the stop of the engine based on the NG result of ID-code collation, however, it is possible to prevent a state in which the engine cannot be restarted. It is preferred to allow starting of the engine irrespective of the ID code collation, when the ECU stores an engine stall occurring previously.

Abstract: An ignition lock for a motor vehicle includes a carrier element for holding an ignition key that is inserted in the ignition lock. The carrier element is movable along a longitudinal axis of the ignition lock. The carrier element pushes a slide bar from a blocking position to an unblocking position when the carrier element moves along the longitudinal axis.

Abstract: In the device a controllable switch is built into the control device which enables the start authorization and by means of which the supply voltage with which this controllable switch is supplied can be switched off. To check a start authorization a diagnosis can be undertaken which is realized with known resistance elements in the voltage supply line between identification device holder and control device. This allows the voltage drops across the elements to be compared with the corresponding required values. Simple short circuiting of the starter or the ignition is thus no longer possible since this would be detected by the control device as a result of the changes in voltage drop. In addition a fault in the supply voltage or the feed lines can be definitively detected.

Abstract: Methods and apparatus are provided for rendering electronic keys left behind in a vehicle temporarily inactive. The apparatus comprises a vehicle security control module in wireless communication with the electronic keys, and having operatively coupled together a receiver, a processor, non-volatile memory and a short-range transmitter. When the module receives a valid lock command from any source it sends a short-range interrogation signal to keys within the vehicle. Left-behind keys respond and send their unique ID(s) to the module's receiver. The processor obtains the unique ID(s) from the receiver and sets one or more inhibit flags in memory or equivalent to identify those keys as left-behind keys. The processor thereafter ignores commands from such left-behind keys, thereby rendering them temporarily inoperative until a valid unlock command is received form another source, whereupon the processor clears the inhibit flags from memory and restores the left-behind keys to active status.
