Abstract

A time-varying signal is applied to at least one coil (14) in magnetic communication with at least a portion of a vehicle (12) susceptible to deformation responsive to a crash. A sense resistor (RS) in series with the at least one coil (14) provides for detecting a current therethrough responsive to a voltage thereacross. The current (iL) 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 (14) 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 (14).
