Patent DE-4307226-A1 (DE)
Inventor: VOLK ANDREW M
IPC: G06F1/32
Filed: 1993-03-08
Abstract: The chip controlling an external device eg a floppy disc drive, monitors its own operating state and switches itself into a lower power consumption state when the chip determines that it is in a predetermined state from which it can power down cleanly.

Title: Device for making and disconnecting the connection between steering wheel and steering gear as an anti-theft protection in motor vehicles
Inventor: OANEA ALEXANDER DIPL ING
IPC: B60R25/022
Filed: 1993-05-17
Abstract: At present, the blocking of the steering column serves as a protection against theft, provided that the locking mechanism is engaged by rotating the steering wheel. Less stable blocking mechanisms can even be damaged by force in order to free the steering wheel. The new device is intended to permit the connection between the steering column and the steering gear to be made when the engine is started and to be disconnected when the engine is switched off. The steering column is divided transversely. The connection between the two sections of the steering column is made by means of 4 bolts actuated by electromagnets when the current supply is switched on by means of the ignition key. When the ignition key is removed from the ignition lock, the current supply to the electromagnets is interrupted, compression springs cause the bolts to be drawn back and as a result disconnect the connection between the two sections of the steering column. In order to enable the supply of current to the electromagnets a supplementary lock is used which is actuated by the ignition key, an infrared irradiator, code card or key board. The device can be used as an optimum means of protecting against theft.
