Abstract: An apparatus for activating an electrically or electronically controlled appliance from an energy-saving passive state, especially a locking system for locking and/or unlocking, in particular for an access and/or authorization and/or for other services for a wireless remote control, for controlling of front doors, for motor vehicles, or the like comprising a first device in the appliance and an associated second device designed in the type of an electronic key, an ID-transponder, a chip card or the like, wherein both devices for the intended operation have transmitters and/or receivers for electromagnetic signals is suggested which allows a large operation distance and a long battery lifetime of the second device. This is achieved in that the first device transmits a first cyclic repeated signal for the activation and/or authentication of the second device with a first data protocol within a first transmission time interval and with a first cycle time.

Abstract: An apparatus for locking and/or unlocking, for an access and/or drive authorization in a motor vehicle of a keyless entry/go functionality, for a wireless remote control of a first device in the motor vehicle and an associated second device designed as an electronic key, an ID-transponder or a chip card, with both devices for the intended operation having transmitters and/or receivers for electromagnetic signals which allows a large operation distance and a long battery lifetime of the second device. The first device transmits a first cyclic repeated signal for the activation and/or authentication of the second device with a first data protocol within a first transmission time interval and with a first cycle time.

Abstract: A safety switching device for driving a plurality of different kinds of guard locking devices is provided. The safety switching device comprises a first terminal and a second terminal for connecting a guard locking device, and a safety processor adapted for controlling drive signals at the first and the second terminal to drive the guard locking device. The safety processor is adapted for determining a kind of a guard locking device connected to the first and/or the second terminal out of a plurality of different kinds of guard locking devices by detecting external electrical connections between the first terminal, the second terminal, and a reference potential. The safety processor is further adapted for controlling the drive signals depending on the determined kind of the guard locking device.
