Patent number: 11366180Abstract: A magnetic field sensor apparatus includes a sensor signal generator generating a sensor signal responsive to a magnetic field. A switching level provider provides during a power up mode a switching level based on a most recently updated valid one of a first and a second value of a default switching level. If an update triggering condition occurs, the not most recently updated one of the first and second values of the default switching level is updated and the most recently updated one of the first and second values of the default switching level is maintained unchanged until a next update triggering condition occurs, so that the first and second values of the default switching level are updated alternately on consecutive triggering conditions.Type: GrantFiled: February 1, 2021Date of Patent: June 21, 2022Inventors: Tobias Werth, Cosmin Filip, Catalina-Petruta Juglan, Silviu-Antonio Pieleanu

Patent number: 10243724Abstract: 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.Type: GrantFiled: March 13, 2017Date of Patent: March 26, 2019Assignee: Infineon Technologies AGInventors: Klaus Grambichler, Simon Hainz, Catalina-Petruta Juglan

Patent number: 9638548Abstract: 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.Type: GrantFiled: June 25, 2012Date of Patent: May 2, 2017Assignee: Infineon Technologies AGInventors: Razvan-Catalin Mialtu, Dan-Ioan-Dumitru Stoica, Heinz Untersteiner, Catalina-Petruta Juglan
