摘要： A plural-frequency capacitive occupancy sensing system comprises an antenna electrode and a detection circuit. The detection circuit is configured to drive the antenna electrode at least with a first and a second signal at a first and a second frequency, respectively, so as to obtain at least a first and a second measurement value indicative of at least one of conductance, susceptance, resistance, reactance and capacitance between the antenna electrode and a reference node, at the first frequency and the second frequency, respectively. The detection circuit compares the capacitance between the antenna electrode and the reference node with a threshold capacitance, the threshold capacitance being derived from a difference between the first and second measurement values and/or the capacitance between the antenna electrode and the reference node being corrected based upon the difference between the first and second measurement values. The detection circuit outputs an occupancy state signal depending on an outcome of the comparison.

摘要： A capacitive sensing system for being connected to a heating element (12) comprises a capacitive detector (24) connectable to the heating element and a common mode choke (28) for essentially preventing alternating current from flowing from the heating element to the heating current supply (22). The capacitive detector is configured for driving an alternating current into the heating element and for producing an output indicative of capacitance based upon the alternating current. The choke has a first (30) and a second (32) winding for connecting the heating element with the heating current supply. The choke comprises a third winding (34) connected in parallel of the first and/or second winding. The capacitive detector is configured for measuring a portion of the alternating current flowing across the third winding and for taking into account the measured portion of alternating current when producing the output.

摘要： A capacitive sensing system (24) for being connected to a heating element (12) producing heat upon electrical current being caused to flow there across comprises a capacitive detector connectable to the heating element and a common mode choke (28) for connecting the heating element with a heating current supply (22). The capacitive detector is configured for driving an alternating current into the heating element and for producing an output depending on the capacitive load, which the alternating current is subject to. Depending on the object to be sensed, the capacitive load is variable in a range between a minimum value and a maximum value. The common mode choke represents an inductive load in parallel of the capacitive load. The capacitive load and the inductive load contribute together to a complex impedance. The inductive load dominates the capacitive load. A compensation capacitor is arranged in parallel of the choke. The compensation capacitor represents an additional capacitive load also contributing to the complex impedance. The compensation capacitor is dimensioned such that the sum of the additional capacitive load and the maximum value amounts to at least 50 % of the inductive load.

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.

The heater network includes a heating element (10) connected between a first node (21) and a second node (22) to dissipate heat.
