Abstract: Aspects of the present disclosure relate to correcting for a phase shift between signals associated with an angle sensor and a multi-turn sensor that includes magnetoresistive elements. A processing circuit can determine a phase shift correction and generate position information based on at least the phase shift correction and a signal associated with the multi-turn sensor.

Abstract: A system includes a multiturn counter that can store a magnetic state associated with a number of accumulated turns of a magnetic field. The multiturn counter includes a plurality of magnetoresistive elements electrically coupled in series with each other. A matrix of electrical connections is arranged to connect magnetoresistive elements of the plurality of magnetoresistive elements to other magnetoresistive elements of the plurality of magnetoresistive elements.

Abstract: Embodiments of the present disclosure provide mechanisms for measuring currents flowing in one or more conductor wires. The mechanisms are based on using magnetic sensor pairs arranged within a housing with an opening for the wires, where each magnetic sensor pair can generate a pair of signals indicative of magnetic fields in two different directions. The outputs of the sensor pairs can be used to derive a measure of current(s) flowing through the one or more wires. The use of magnetic sensor pairs that can measure magnetic field in two different directions may enable simultaneous current measurement in multiple wires placed within the opening, improve accuracy of current measurements while relaxing requirements for precise control of the placement of the wire(s), reduce the impact of stray magnetic interference, and enable both AC and DC measurements.

Abstract: A magnetic field sensor is disclosed. The magnetic field sensor includes a first magnetoresistive element and a second magnetoresistive element arranged as a half bridge. The magnetic field sensor also includes two or more conductors adjacent to the first magnetoresistive element and the second magnetoresistive element. The two or more conductors can carry a bias current and a compensation current such that the bias current and the compensation current flow in the same direction adjacent to the first magnetoresistive element while the bias current and the compensation current flow in opposite directions adjacent to the second magnetoresistive element.

Abstract: This disclosure describes, among other things, embodiments of devices, systems, and methods for using 3-dimensional (3D) magnetic sensors to detect the position of a magnetic target. By using 3D magnetic sensors, a two dimensional array of such magnetic sensors can be used to determine a 3D position of a magnetic target.

Abstract: Aspects of this disclosure relate to a magnetic sensor system for measuring any desired combination of measuring torque, rotation angle, and turn count of a shaft. The shaft may include two portions connected by a torsion element. The system can measure rotation angle using a magnetic target coupled to the shaft that produces a magnetic field that varies as a function of rotation angle. The system can measure torque applied to the shaft by measuring the difference in rotation angles between the two portions of the shaft and factoring in a torsion coefficient. The system can track a turn count of the shaft using a multi-turn sensor. The magnetic sensor system may be part of an electric power assisted steering (EPAS) system.

Abstract: Sensor error detection with an additional channel is disclosed herein. First and second magnetic sensing elements can be disposed at angles relative to each other. In some embodiments, the first and second magnetic sensing elements can be magnetoresistive sensing elements, such as anisotropic magnetoresistance (AMR) sensing elements. Sensor data from first and second channels, respectively, having the first and second sensing elements, can be obtained. Third channel can receive a signal from the first sensing element and a signal from the second sensing element, and sensor data from the third channel can be obtained. Expected third channel data can be determined and compared to the obtained third channel data to indicate error.
