    摘要： A dual-electrode occupant (12) detection system (10) configured to determine an occupant (12) presence on a seat assembly (32). The system (10) includes two electrodes (20, 28) that each generates an electric field in response to an applied excitation signal (50). The two electrode signals arising therefrom can be measured individually and/or combined to detect more reliably an occupant (12). Such a configuration advantageously avoids the added expense and complication of an electrode arrangement that relies on an underlying shield layer to reduce electrode signal (24) degradation caused by a seat heater element.

    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： The invention relates to a measuring system comprising at least one first measuring means for detecting at least one frequency-independent electrical variable, an evaluation unit for detecting the temporal behavior of the frequency-independent electrical variable, the evaluation unit automatically generating a signal based on the detection of the evolution in time of the frequency-independent electrical signal, said signal being at least partially equivalent to a frequency-dependent signal. The invention also relates a measuring method. According to said method, at least one first measuring means detects at least one frequency-independent electrical variable and an evaluation unit detects the temporal behavior of the frequency-independent electrical variable, the evaluation unit automatically generating a signal based on the detection of the evolution in time of the frequency-independent electrical variable, said signal being at least partially equivalent to a frequency-dependent signal.
