  • Patent number: 11073408
    Abstract: A rotary sensor arrangement is configured to be used with a rotatable magnetic source and comprises a first and a second pair of magnetic field sensors, each pair arranged symmetrically with respect to rotation axes and providing respective sensor values. An evaluation unit determines a first sum value corresponding to a sum of the sensor values of the first pair, and a second sum value corresponding to a sum of the sensor values of the second pair. The evaluation unit further determines a difference value corresponding to a difference between the first and the second sum value and compares the difference value or a value derived thereof to a threshold value. Based on the comparison result, it is determined whether a failure status of the sensor arrangement is present.

  • Patent number: 11041931
    Abstract: A voltage measurement device includes a voltage measurement circuit part, a voltage generation circuit part, and a control unit. In a voltage measurement mode, a measurement result of the input voltage is detected as an output voltage value based on the output signal of the voltage measurement circuit part. In a self-diagnosis mode, it is determined whether the measured output voltage value when the lower limit voltage is applied by the voltage generation circuit part is within a specific lower limit range (first determination). Further, a specific intermediate range is set based on the output voltage value and a specific upper limit range, and it is determined whether the output voltage value when the intermediate voltage is applied by the voltage generation circuit part is within the specific intermediate range (second determination). Self-diagnosis of the voltage measurement circuit part is performed based on the first and second determinations.
