Patent ID: 8368393

Claim:
A measurement method, comprising the steps of: provision of an array of magnetic field sensors, each emitting a sensor signal as a function of a magnetic field intensity; provision of a sector-wise magnetized magnetic source that is arranged movably with respect to the array; determination of a rotational value of the magnetic source relative to the array as a function of the emitted sensor signals; derivation of a set of N sensor values from the sensor signals; ascertainment, based on the previously determined rotational value, of a number K of sets S k of reference values s k,i corresponding to a number K of redetermined positions of the magnetic source, wherein each of the sets S k comprises a number N of reference values that corresponds to the number N of sensor values, and wherein the index i can take on values from 1 to N and the index k can take on values from 1 to K; performance of a comparison operation between the set of sensor values and the number of sets S K of reference values; and selection of a position from the number of predetermined positions as a function of the comparison operation.
