There is described a method for enabling the operation of automation components of a technical system via a mobile control and monitoring device. In a first step, the control and monitoring device receives a first identification from a first transponder device, with the first transponder device being attached to the technical system, with the first transponder device having been activated by the automation components and with the first identification having been transmitted via a wireless communication connection from the automation components to the mobile control and monitoring device. In a further step the communication connection between the control and monitoring device and the automation components is deactivated. The mobile control and monitoring device sends a carrier signal and following that receives the carrier signal modulated by the first transponder device. A first distance between the control and monitoring device and the first transponder device is then determined from the modulated carrier signal. In addition, a first radio-determined identification from the first transponder device is determined from the modulated carrier signal. Following the reception of the modulated carrier signal, the communication connection is reactivated. If the first distance is shorter than a predetermined first distance and if the radio-determined first identification corresponds to the first identification, the operation of the automation components is enabled.

A charging device (BEV) on an vehicle (FAR), for a dual toll system (SYS), is capable of receiving positional data from a position determining system (PES), concerning the actual location of the vehicle (FAR) and to calculate location co-ordinates (OKO) for the vehicle (FAR). Said charging device (BEV) is further capable of calculating a characteristic signature (SIG) for the stretch of road (STR) traveled by the vehicle (FAR) by means of location co-ordinates (OKO) for the vehicle (FAR) and transmitting the same to an accounting centre (ABZ), outside the vehicle.

A method for controlling a power supply of a mobile data memory (MDS). The mobile data memory is operable to communicate via wireless data transfer using an antenna (A). The mobile data memory has at least one energy accumulator (BAT), a data demodulator (EMP), a data processing unit (C) and an electronic memory (MEM). The method includes switching to a standby mode from a full operation mode, the standby mode having a lower energy supply than the full operation mode but permitting receipt of the signal. When the mobile data memory receives a signal (ES), the received signal is evaluated to detect at least one backscatter frequency and an associated communication frequency (f, f).

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

A method for determining the distance between a base station (SLG) and a mobile object (DT&#x2013;DT). A HF carrier frequency and an offset frequency (df) are predetermined for a QAM modulation. The HF carrier frequency is increased and decreased by the offset frequency in sequence over time in such a way that the HF carrier base frequencies (fo+df, fo&#x2212;df) resulting in an HF carrier signal (TS) thus modulated exhibit an identical phase when the frequency is changed. The HF carrier signal is subsequently transmitted and simultaneously mixed (MIX) with an HF carrier signal (RS) that has been backscattered by the mobile object to obtain a carrier phase signal (PS). The corresponding carrier phase (PH, PH) for the two HF carrier base frequencies is determined in sequence over time. The difference (dPH) between these phases is used to calculate the distance between the base station and the respective mobile object.

A method and system for transferring data between at least one read/write device (RWD) and at least one mobile data memory (MDM). The mobile data memory (MDM) is preferably attached to an object for recording object-related status and/or process data, e.g. in a dispatch, transport and/or manufacturing system for the individual objects. According to the method, a difference in transfer time between the received data signals of a mobile data memory (MDM) and transmitted data signals of the read/write device (RWD) is determined in the read/write device (RWD) and the received data signals of the mobile data memory (MDM) are processed further in said read/write device (RWD) only if the difference in transfer time which has been determined lies within a predefined transfer time limit.

An access control system for an object, particularly a motor vehicle, comprises at least one base station with a transceiver device that transmits a wideband modulated interrogation signal, at least one transponder that has a modulation device, in order to modulate an auxiliary carrier signal, the frequency of which is changed between an infinite number of frequency positions, onto an interrogation signal received at a distance from the base station and reflect it as a code-modulated response signal, and an evaluation device that is connected after the transceiver device and that evaluates the response signal in sidebands of the changed frequency positions, with respect code and distance.

A method and circuit for transmitting a data-modulated high-frequency data signal ffrom a transmitter to a receiver, for transmitting data between a read-write device (RWD) and at least one mobile data memory (MDM) in an identification system that has a number of mobile data memories (MDM) which are placed on objects and which are provided for detecting object-specific status data and/or process data. Such an identification system is particularly useful, e.g., in a shipping, transport and/or manufacturing system of the individual objects. In addition to the transmitted high frequency data signal f, a further high-frequency data signal fis transmitted, which serves to convert the frequency and/or to modulate the carrier code of the high-frequency data signal f.
