摘要： The present invention proposes to compensate the effect of the seat heater by either direct measurement of the current coupled into the seat heater or by indirect compensation by introducing an additional electrode into the system. This additional electrode, subsequently referred to as 'compensation electrode', may be integrated into the capacitive measurement system in such a way, that the capacitance between the sense electrode and this compensation electrode is subject to the same relative variations as the capacitance between the sense electrode and the seat heater.

摘要： An RFID transceiver unit (10) for detecting an RFID transponder said transceiver unit comprises a transmitter associated with a loop-shaped transmitting antenna (12) for transmitting an electromagnetic excitation field and a receiver associated with a loop-shaped receiving antenna (14). When the RFID transponder (18) is excited by the excitation field (24), the RFID transponder emits an electromagnetic response field, which induces a transponder signal in the receiving antenna. The received signal generated by the receiving antenna in response to an electromagnetic field thus contains the transponder signal. The received signal of the receiving antenna generally contains an interfering signal directly induced by the excitation field in the receiving antenna. The transceiver unit comprises means for attenuating the interfering signal in the received signal.

摘要： A combined seat heater and capacitive occupancy sensor comprises a heater network and a capacitive sensing network. The heater network includes a heating element (10) connected between a first node (21) and a second node (22) to dissipate heat. The capacitive sensing network is connected to the heating element to apply an oscillating current thereto and to derive a capacitive load of the heating element from the voltage resulting on the heating element. The heater network comprises a common mode choke (16) connecting the first and the second node to a third (23) and a fourth (24) node, respectively. The capacitive sensing network further comprises means to sustain the oscillating current in or to drive the oscillating current into the heating element as well as a high - impedance amplifier (32) having an input node operatively connected to the heating element to probe the resulting voltage, and an output node (44) to provide an output signal indicative of the voltage.
