In addition, the invention relates to an apparatus with an RFID reader of this type.

Abstract: A radio method for doors in the 2.4 GHz frequency band with operating channels, wherein a stationary unit is bidirectionally networked by means of a wireless radio connection with at least one battery-powered mobile unit and uses a frequency-hopping method, wherein channel hops are executed in a time raster between 0.625 ms and 10 ms, the channels used for the frequency-hopping method are adaptively selected, at least one complete communication cycle takes place on one channel within the time raster, the number of transmitted data is adapted to the useful data that must be transmitted, the synchronization for establishment of a connection between the stationary unit and the mobile unit takes place on a synchronization channel.

Abstract: A monitoring method and a monitoring device for a motor-driven door, wherein a stationary unit and a monitoring device mounted on the movable door communicate bidirectionally with one another, wherein data and/or signals of at least one door safety sensor are relayed to the stationary unit, and wherein a waking device is automatically wakened cyclically or is wakened by a vibration sensor and wakes the control device, which in turn wakes the transmitter/receiver and actively queries the stationary unit assigned individually to it as to whether the monitoring device must remain active or be switched back to a power-saving idle state.

Abstract: An electronic circuit for a high-frequency switch for opening an antenna resonance circuit of an RFID system, wherein the high-frequency switch can be opened and closed by d.c. voltages, in which circuit a rectifier circuit generates the blocking voltage for opening the high-frequency switch from the high-frequency supply voltage, the rectifier circuit is designed such that it generates a blocking voltage whose value corresponds at least to the peak-to-peak value of the high-frequency voltage to be switched, the blocking voltage is conducted via the same electric connecting line via which the high-frequency supply voltage and a closing voltage are also conducted to the antenna of the RFID system, and a resistor is connected in parallel with each of the PIN diodes, which are series-connected with respect to direct current.

Abstract: A method for data transmission between a write/read station of a radio frequency identification system and at least one external functional unit sends at least one data block from the write/read station to the external functional unit. The transmitted data block is received by at least one of the external functional units, and after reception of the transmitted data block, at least one external functional unit evaluates the at least one data block. The transmission of the at least one data block takes place exclusively by way of an RFID communication connection from the write/read station to the at least one functional unit and/or back.

Abstract: The invention relates to a method for controlled braking of an electrically powered lifting action in the event of a failure, such that at least one of the nominal values for “rotational direction” and/or “operating speed” and/or “door position” and/or “motor capacity” and/or “motor current” is ascertained and compared with an actual value, and such that a motorized braking process or motorized stopping process is triggered by a departure of the actual value from the nominal value that lies outside a predetermined range. In addition the invention relates to a device for applying said method.

Abstract: A position transmitter for determining a position of a rotating shaft, has an AMR sensor unit or a GMR sensor unit which, for determining the position, has only one magnet disposed on a shaft to be monitored, whereby the position transmitter can be used as a single-turn and a multi-turn unit. Furthermore, a method for determining a position of a rotating shaft with the position transmitter is also provided. In accordance with the method, signals are produced using a diametrically magnetized magnet in a sensor unit, so that sine and cosine signals are obtained as output signals of the AMR sensor unit, the sine and cosine signals are digitalized, and these signals are processed by a microcontroller, with regard to the detection and evaluation of the angle of rotation, for detecting, filtering, and evaluating the number of revolutions, for detection of the direction of rotation or for data transmission of the angle of rotation and the number of revolutions to an overriding control.

Abstract: An antenna array for RFID antennas for large cohesive detection spaces, having an operating frequency between 100 kHz and 30 MHz. This antenna array can be connected with at least one reader. There can be at least one antenna consisting of an antenna loop having at least one winding. The antenna array can include at least two antennas that are disposed in a plane, in such a manner that the antenna loops of the individual antennas overlap. With this design, at least one multiplexer can be disposed between the at least one reader and the antennas of the antenna array, for selected activation of the antennas.
