1. An apparatus for determining the position of a first and a second element relative to each other comprising:

  • a magnet being attached to the first element, said magnet having a magnetic flux density;

    a first sensing device being adapted to detect said magnetic flux density and responsively generate a first signal, said first device being attached to said second element;

    a second sensing device being adapted to detect said magnetic flux density and responsively generate a second signal, said second device being attached to said second element; and

    a controller adapted to receive said first and said second signals and responsively determine a position of said first element relative to said second element.
