  • Patent number: 10466310
    Abstract: A magnetic field sensor arrangement includes a magnetic field sensor element configured to provide a sensor output signal responsive to a magnetic field, wherein the sensor output signal is representative of a magnetic field amplitude; a processing module configured to provide a processed sensor output signal representative of the sensor output signal; a switching level calculation module configured to calculate a switching level, (1) during a power up mode, based on a default switching level, and (2) during a running mode, based on the processed sensor output signal; a comparator module configured to compare the processed sensor output signal with the switching level, and to provide a comparator output signal based on the comparison; and a storage module configured to store the default switching level, provide the default switching level during the power up mode, and update the default switching level during the running mode.

  • Patent number: 10243724
    Abstract: A sensor device includes a memory circuit and a transmission circuit. The transmission circuit sends a first data signal to an external receiver in a first state of a read-out-mode of the sensor device, if an oscillation period of the oscillating quantity is longer than a period threshold. Further, the transmission circuit sends a second data signal to the external receiver in a second state of the read-out-mode, if the oscillation period of the oscillating quantity is shorter than the period threshold. The second data signal contains information on at least one of a first local extremum sensor data value and a succeeding second local extremum sensor data value.

  • Publication number: 20180274951
    Abstract: Switching threshold determination systems and methods for sensors are described. Individual rising and/or falling edge maxima of a target can be determined. Based on the maxima, individual rising and/or falling edge thresholds can be determined. The individual rising and falling edge thresholds can be used to detect one or more target of the target wheel.

  • Patent number: 9638548
    Abstract: Embodiments relate to predictive output switching threshold determination systems and methods for sensors, for example magnetic field sensors. In embodiments, at least one individual switching threshold is determined predictively, rather than reactively, for each tooth or pole of a ferromagnetic tooth or pole wheel, respectively. For example, in one embodiment, the number of teeth or poles is programmed, and an optimal threshold for each tooth or pole is determined during a rotation of the wheel. The determined optimal threshold for each tooth is then used for that tooth in at least one subsequent rotation of the wheel, with calibration optionally taking place in future subsequent rotations. Thus, in embodiments, thresholds are predictive for each individual tooth or pole rather than reactive to an adjacent tooth or pole.
