  • Patent number: 11821760
    Abstract: By a relative movement between an arrangement of at least three magnetic field sensors and a magnetic field generator, different discrete positional relationships can be produced between the same. A first signal is calculated as a first linear combination using at least two of three sensor signals. It is checked whether the first signal uniquely indicates one of the different discrete positional relationships. If yes, it is determined that the arrangement is located in the one discrete positional relationship. If no, a second signal is calculated as a second linear combination using at least two of the three sensor signals, at least one of which differs from the sensor signals used in the calculation of the first signal, and at least the second signal is used to determine in which of the different discrete positional relationships the arrangement is located relative to the magnetic field generator.
