Abstract
A movable target having individually identifiable magnetic irregularities and a stationary magnetosensitive array and circuit for sensing the magnetic irregularities to thereby provide position of the moveable target relative to a fixed initial location. A method to determine a present position of the target origin including the steps of: identifying a magnetic irregularity of the moveable target; determining a first distance, Y, equal to a distance of the identified magnetic irregularity to a target origin; determining a second distance, X, equal to a distance of the identified magnetic irregularity to the array origin; and determining a distance, L, of the target origin with respect to the fixed initial location, according to a relation: L=L+X−Y.
