A seat monitoring system for monitoring a state of at least one seat arrangeable in a vehicle's interior and determining the position of the seat in the interior. The monitoring system has a control module, two sending modules signally connected to the control module, and at least one seat module associated with at least one seat and a receiving module. The two sending modules are spaced apart from one another and each have one antenna, the receiving module has two antennas. A first antenna of the receiving module is configured to receive a signal from a first sending module of the sending modules, and a second antenna of the receiving module is configured to receive a signal from a second sending module of the sending modules. The receiving module is configured to determine signal strengths of the signals received by the antennas of the receiving module for position determination.

A lock system for access authorization in a motor vehicle, having a first device which has at least two states and is embodied as a control device, and having an associated second device which is embodied in the manner of an electronic key, an ID signal transmitter, a chip card or the like. The two devices have transmitters and/or receivers for electromagnetic signals. At least one of the signals transmitted between the second device and the first device is an encoded operating signal for authenticating the second device, with the result that after a positive evaluation of the transmitted operating signal when the second device is authorized it is possible to bring about a change in the state of the first device.
