A continuous wave radar system has a transmit and receive module and at least one transponder device, a mobile control and monitoring device and an HMI system.

Abstract: A method for assigning a position of a tire, having a tire sensor, on a vehicle, includes transmitting, with the sensor, a signal including at least an identification number of the sensor following activation by a signal from an LF antenna connected to an evaluation unit. At a system start time, the evaluation unit first initiates an initialization including determination of the position of each tire having a sensor.

A device and a system for measuring air pressure in a vehicle tire are also provided.

Abstract: The invention relates to a method for reduction of the power consumption of a mobile data memory with a non-contact data transmission by means of a read/write device. According to the invention, the mobile data memory, containing at least one energy store and user, is supplied, at least during a cyclic inactive idle mode, with a first clock frequency from a first oscillator and, for data receipt at least during a cyclic request time, with a second higher clock frequency from a second oscillator. The second clock frequency is determined above all for data modulation of a received signal, obtained from the reception antenna or from a combined transmission/reception antenna on the mobile data memory. The invention further relates to a mobile data memory and an identification system with at least one read/write device and one mobile data memory. The advantage of requiring no battery exchange during the life of the mobile data memory is thus conferred.

Abstract: The invention relates to a device for occupant protection in a motor vehicle and for anti-theft protection of the motor vehicle, comprising an airbag (3), which may be inflated with gas by means of a filling device, a transceiver (5), for electromagnetic waves (6) and an occupant protection analytical unit (81) connected thereto. An occupant protection interrogation unit (41) is arranged on the inflatable airbag (3), which is wirelessly interrogated by the transceiver (5). Information on the degree and/or speed of unfolding of the airbag is thus provided to the occupant protection analytical unit (81). The transceiver (5) may furthermore wirelessly interrogate a portable anti-theft interrogation unit (42), for example, a chipcard and hence provide an anti-theft analytical unit (82) with information about the authorisation of the anti-theft interrogation unit (42) and/or the separation of the anti-theft interrogation unit (42) from the transceiver (5) based on the returned signal.

Abstract: A method for transmitting data between a read/write unit (SLG) and one or more mobile data stores (D, HD) in an identification system. The method includes dividing the data transmission occurring between the read/write unit (SLG) and the data stores (D, HD) into a plurality of timeslots (SLOT), subframes (SUBFRAME) and frames. An identification timeslot (S-CH) from the respective data store (D, HD) is received and evaluated in at least one evaluation timeslot (SOa) and the data store is identified as a mobile high-speed data store (HD) if the identification timeslot (S-CH) is a high-speed identification timeslot (S31,0, S0,31), and an associated data-store identifier block (MB2) is evaluated at least beginning during the subsequent timeslot after the identification timeslot (S-CH) onward. The method provides for very rapid detection of high-speed data stores (HD).
