Patent number: 10557765Abstract: A sensor device includes a base element extending in an axial direction and a first magneto elastic active region representing a first longitudinal section of a surface of the base element. The first longitudinal section extends in the axial direction and is magnetized in a first circumferential direction. The sensor device further comprises a first magnetic field sensor overlapping with the first longitudinal section, and a second magnetic field sensor disposed at a distance with respect to the first magnetic field sensor along the axial direction and overlapping with the first longitudinal section.Type: GrantFiled: August 14, 2018Date of Patent: February 11, 2020Assignee: POLYRESEARCH AGInventor: Josua Lanter

Patent number: 10336273Abstract: A sensor system for detecting an adjustment position of a vehicle seat, the sensor system having a Hall sensor and a first preloaded magnet, and it is free of flux concentrators and shielding sheets. The Hall sensor and the first preloaded magnet are arranged along a longitudinal extension of the upper rail that is movable lengthwise such that during adjustment of the upper rail, passage of a free longitudinal end of the stationary lower rail will be monitored and result in a change of an output signal of the Hall sensor.Type: GrantFiled: March 13, 2017Date of Patent: July 2, 2019Assignee: POLYRESEARCH AGInventors: Josua Lanter, Silvano Buergler, Beat Joerimann, Carsten Kaebisch

Patent number: 10011241Abstract: A sensor system is disclosed for detecting positions of two at least partially ferritic components that can move relative to one another, namely a stationary component and a component that can move lengthwise along a longitudinal extension of the stationary component, which are mounted right next to one another. The sensor system can include a Hall sensor and a preloaded magnet, eliminating flux concentrators and shielding sheets. The Hall sensor and the preloaded magnet are arranged along a longitudinal extension of the movable component such that relative movement of the two components is detected by monitoring a free longitudinal end of the stationary component.Type: GrantFiled: June 10, 2016Date of Patent: July 3, 2018Assignee: POLYRESEARCH AGInventor: Josua Lanter

Patent number: 9494556Abstract: A force measurement sensor for measuring an applied force onto an object is provided. The force measurement sensor includes a sensing unit including a concentrator, a generator, a detector, and an evaluator. The concentrator points towards the object. The generator generates a magnetic field. The detector detects a magnetic field generated by the generator and influenced by the applied force to be measured. The detector outputs a first signal of the detected magnetic field. The evaluator evaluates a signal strength of the signal and determines the applied force based on the signal. A longitudinal axis of the detector is arranged for a lateral offset between the longitudinal axis of the detector and a central axis of the concentrator that is perpendicular to a longitudinal direction of the concentrator.Type: GrantFiled: January 10, 2013Date of Patent: November 15, 2016Assignee: POLYRESEARCH AGInventor: Lutz May
