Abstract
A magnetic sensor comprises at least one first coil at an associated at least one first location of a body of a vehicle and operatively connected to a ferromagnetic element of the body. A signal comprising a leading edge is applied to the at least one first coil, and a second signal is sensed from the at least one first coil, wherein said second signal is responsive to the interaction of the first signal and the ferromagnetic element, and a magnetic disturbance is localized or a crash is discriminated responsive to the second signal.
Claims11
A magnetic sensor, comprising:
- a. at least one first coil at an associated at least one first location of a body of a vehicle, wherein said at least one first coil is operatively coupled to a ferromagnetic element of said vehicle body;
- b. a first signal operatively connected to said at least one first coil, wherein said first signal comprises a leading edge;
- c. a means for sensing at least one second signal from said at least one first coil, wherein said second signal is responsive to the interaction of a magnetic field with said ferromagnetic element of said vehicle body, wherein said magnetic field is generated by said at least one first coil responsive to said first signal;
- and
- d. a means responsive to said at least one second signal for discriminating a crash involving said ferromagnetic element of said vehicle body.
