A torque sensor assembly for use in a vehicle power steering system has magnets, coaxial first, second, and third flux closure members around the magnets, and first and second magnetic sensors. Each of the plurality of magnets emits a magnetic field. The second flux closure member is between the first and third flux closure members. The first and third flux closure members collect the magnetic fields having a first polarity. The second flux closure member collects the magnetic fields having a second polarity that is opposite the first polarity. The first and second magnetic sensors are positioned to have like polarity. The first sensor is between the first and second flux closure members. The second sensor is between the second and third flux closure members. A torque signal is calculated by subtracting a second signal generated by the second sensor from a first signal generated by the first sensor.

Torque sensor assembly for vehicle power steering systems

A tire pressure monitoring system () for an automotive vehicle () has a receiver circuit (). The vehicle () has a plurality of wheels (A-D). A plurality of antennas (A-D) are adjacent to one of the wheels (A-D). The plurality of antennas receive RF signals from a pressure sensor (A). An adder circuit () is coupled to the receiver circuit and the plurality of antennas. The adder circuit receives the RF signals and adds them together to form a sum signal. The sum signal is coupled to the receiver circuit.
