Abstract:
The invention is a method for tracking a position of a magnet moving relative to a magnetometer array. On the basis of the magnetic field detected by each magnetometer of the array, the position of the magnet is estimated. This estimation is based on taking into account a reference magnetic field established beforehand, this reference magnetic field being subtracted from the magnetic field detected by each magnetometer, so as to form a differential measurement. The various successive estimations of the position of the magnet allow its path to be tracked.

Claim (Index 24):
A method comprising using a magnetometer array in connection with generating an estimate a position of a magnet that is being moved relative to said magnetometer array that comprises magnetometers, wherein each magnetometer is configured to measure a magnetic field generated by said magnet along at least one measurement axis, wherein estimating said position comprises executing a first step, executing a second step, executing a third step, executing a fourth step, executing a fifth step, and executing a sixth step, wherein said first step comprises, at a reference time, using each magnetometer to measure a reference magnetic field, wherein said second step comprises assigning a reference position to said magnet at said reference time, said reference position being assigned to one of an arbitrary position and an estimate of said position of said magnet at said reference time, wherein said third step comprises using each magnetometer to measure a magnetic field generated by said magnet at a measurement time after said reference time, wherein said fourth step comprises calculating a differential magnetic field, wherein, for each magnetometer, said differential magnetic field represents a difference between said magnetic field measured in said third step and said reference magnetic field measured in said first step, wherein said fifth step comprises using a recursive estimator to generate an estimate of a position of said magnet at said measurement time, wherein said estimate is based at least in part on each differential magnetic field and on an estimate of said reference position, wherein, in a first iteration, said reference position of said magnet is a position that was assigned to said magnet at said reference time, and wherein said sixth step comprises repeating said third step, said fourth step, and said fifth step based at least in part on said estimate generated by said recursive estimator in said fifth step while incrementing said measurement time.
