A seat system for a mass transit vehicle configured to provide at least one seating position, which includes a seat cushion configured to support at least one occupant; a seat back configured to support at least one occupant; one seat belt device for each seating position configured to provide restraint to an occupant, which includes a first sensing mechanism to detect and output a first signal indicating whether the seat belt device is configured in one of two positions, a first unbuckled position and a second buckled position; an electronic control unit, coupled to a vehicle voltage source, having at least one input connection, at least one output connection, a microprocessor to process data received through any input connection, and a memory device to store data processed by the microprocessor; at least one communication means coupled to the electronic control unit for communicating externally to the seat system; and a second sensing mechanism to determine whether the seat is configured in one of two positions, a first unoccupied position and a second occupied position.

Seating system for mass transit vehicle

A magnetic field is generated by at least one coil in magnetic communication with at least a portion of a vehicle responsive to a first time-varying signal operatively coupled to the at least one coil in series with a sense resistor. A second signal is generated responsive to a voltage across the sense resistor and is response to a magnetic condition of the at least one coil, which is response to the magnetic communication of the at least one coil with the portion of the vehicle.

Magnetic crash sensor

First and second complementary voltage signals are operatively coupled across a series circuit comprising first and second sense resistors and a circuit element therebetween. An output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor, and at least one of the first and second complementary voltage signals is controlled responsive to the output signal so as to provide for attenuating at least one noise signal having a frequency that is substantially different from a frequency of the first and second complementary voltage signals.

Signal processing system and method

First and second complementary voltage signals are operatively coupled across a series circuit comprising first and second sense resistors and a circuit element therebetween. A DC bias current in the series circuit is substantially nulled, and an output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor.

First and second complementary voltage signals are operatively coupled across a series circuit comprising first and second sense resistors and a circuit element therebetween. A voltage across the circuit element is regulated in reference to a predetermined level, and an output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor.

A time-varying signal is applied to at least one coil in magnetic communication with at least a portion of a vehicle susceptible to deformation responsive to a crash. A sense resistor in series with the at least one coil provides for detecting a current therethrough responsive to a voltage thereacross. The current is responsive to a magnetic condition affecting the magnetic field generated by the at least one coil, responsive to the reluctance of a magnetic circuit with which the at least one coil is in magnetic communication, and responsive to associated eddy currents in proximal conductive elements, responsive to the magnetic field generated by the at least one coil.
