Abstract
A coil at a first location in magnetic communication with a door of a vehicle generates a magnetic field responsive to a time varying signal applied thereto. The first location and the coil are adapted so that the magnetic field is influenced by an opening state of the door, and by a crash involving the door. A signal is generated from the coil responsive to the time-varying signal and to the magnetic field, wherein the signal provides for sensing an opening state of the door and for sensing a crash involving the door.
