The processor also calculates values related to an actual magnetic field strength using {TAIL ~ the set} of signals from the magnetic sensors and determines values related to the location of each of the plurality of magnets based on {HEAD ~ a difference} between the values related to the predicted magnetic field strength and the values related to the actual magnetic field strength
