摘要： An impedance measurement circuit for determining a complex impedance (1, 2) of a capacitive sensor having at least one sense electrode operable in loading mode and at least one guard electrode comprises: a pulse generator unit for providing a periodic electric measurement signal and a periodic electric guard signal; a signal sensing circuit for sensing a sense current flowing through the at least one sense electrode or the sense electrodes in response to the pulse generator unit measurement signal; and a control and evaluation unit. The control and evaluation unit is configured for determining a complex impedance (1, 2) from the determined sense currents with reference to a complex reference potential.

摘要： Seat monitoring system (11) for monitoring an occupancy related status of at least one seat (14, 18) inside an automotive vehicle compartment (10), the seat monitoring system comprising a control module (20) mounted within the compartment, and at least one sensor module (26) integrated into the at least one seat. The sensor module comprises a sensing system (30) for sensing an occupancy related status with respect to the seat, wherein said control module is arranged in wireless communication with said sensor module. The control module comprises at least three transmitting RF antennas (24) configured to transmit a request signal in at least three directions inside the vehicle compartment; and the sensor module (26) is further configured to receive the request signals from the at least three directions, to determine reception parameters of said request signals, and to transmit an information responsive to said reception parameters to said control module (20).
