Occupant classification system

摘要

The disclosed capacitance sensing apparatus may be used in an occupant classification system. The sensing apparatus may comprise a sensor pad, a sensing element disposed on the sensor pad for sensing capacitive current, at least one additional electronic element disposed on the sensor pad for providing information related to another parameter, and a switching mechanism. The switching mechanism may electrically connect the at least one additional electronic element to the sensing element during the capacitance measurements and electrically disconnect the at least one additional electronic element from the sensing element after the capacitance measurement.
