Abstract:
1. A magnetic sensor, comprising: a. at least one coil operatively associated with a magnetic circuit of a vehicle body or structure, wherein said magnetic circuit comprises at least a portion of said vehicle body or structure, said at least one coil is adapted to cooperate with a time-varying magnetic flux in said vehicle body or structure, said time-varying magnetic flux is generated or sensed by said at least one coil, and said time-varying magnetic flux is responsive to a condition of said vehicle body or structure that is sensed by the magnetic sensor, and b. at least one electrical circuit operatively coupled to said at least one coil, wherein said at least one electrical circuit is adapted so that said at least one coil in cooperation with said at least one electrical circuit exhibits a resonant or near-resonant condition in association with said time-varying magnetic flux for at least one condition of said vehicle body or structure.
