Abstract
A member having a magnet attached is moveable along a path which has an array of magnetic field sensors adjacent the path. Each sensor provides a bipolar output signal as the magnet passes. A plurality of sensors provide a plurality of output signals for a first position of the magnet. Electronic means fit the plurality of output signals to a first curve having a crossover point to determine the first position.
