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.
