Abstract:
A position sensing system includes a member movable along a path, the member having an elongated magnet extending along the path, the magnetic field orientation of the elongated magnet being at an angle with respect to the path. A sensor determines a position of the member along the path based on a measurement of a magnetic field generated by the elongated magnet.
