Magnetic crash sensor

摘要

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.
