  • Publication number: 20200400462
    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.

  • Patent number: 10866152
    Abstract: A concept for torque measurement on a shaft is described. To that end, millimeter waves are transmitted in the direction of a first encoder structure, which is coupled to a first shaft section of the shaft for conjoint rotation and is arranged around the shaft, and in the direction of a second encoder structure, which is coupled to a second shaft section of the shaft for conjoint rotation and is arranged around the shaft. The first encoder structure and the second encoder structure are rotatable relative to one another in the case of a torque to be transmitted via the shaft. At least one reception signal is generated on the basis of millimeter waves reflected or transmitted by the first and second encoder structures. A torque transmitted using the shaft is determined on the basis of the at least one reception signal.
