Abstract: A movement sensor comprises a multi-pole ring magnet, a semiconductor substrate, a first magnetic sensor formed on the semiconductor substrate, and a second magnetic sensor formed on the semiconductor substrate. The first magnetic sensor is configured to produce a first output signal in response to movement of the multi-pole ring magnet, and a centroid of the first and second magnetic sensors are separate and radially aligned on the semiconductor substrate relative to the multi-pole ring magnet. The second magnetic sensor is arranged at a predetermined angle with respect to the first magnetic sensor and is configured to produce a second output signal in response to the movement of the multi-pole ring magnet. The predetermined angle is between 0° and 90° exclusive and is configured to produce a difference in phase between the first and second output signals in response to the movement of the multi-pole ring magnet.

Abstract: A linear actuator comprising a first assembly, a second assembly, and a magnetic sensor. The second assembly is linearly movable with respect to the first assembly such that the linear actuator is configured so as to be in one of a plurality of linear positions. The first assembly and the second assembly cooperatively define a magnetic pathway. The magnetic pathway is configured to vary in length with linear movement of the first assembly with respect to the second assembly. The magnetic sensor is configured to output a signal indicative of the magnetic field flux routed via the magnetic pathway.

Abstract: A multi-turn angular position sensor includes a fixed magnet non-rotationally coupled to a fixed structure. A shaft is configured to rotate multiple complete rotations from a reference position, where each complete rotation front the reference position in a rotational direction defines a unique rotation zone of the shaft. Rotatable magnets surround the shaft and are disposed between the shaft magnet and the fixed magnet and are configured to rotate a different number of angular degrees than the shaft magnet. One of the rotatable magnets is a zone sensor magnet that rotates no more than one complete rotation from the reference position. A rotational zone sensor supplies a zone sensor output signal that indicates the unique rotation zone of the shaft. A shaft rotation sensor supplies a shaft rotation output signal representative of a number of angular degrees that the shaft rotates within each unique rotation zone.

Abstract: A method and system for orienting and calibrating a magnet for use with a speed sensor. A magnet can be mapped two or more planes thereof in order to locate the magnet accurately relative to one or more magnetoresistive elements maintained within a speed sensor housing. An optical location of the magnet with respect to the magnetoresistive element and the sensor housing can then be identified in response to mapping of the magnet. Thereafter, the magnet can be bonded to the speed sensor housing in order to implement a speed sensor thereof maintained by the speed sensor housing for use in speed detection operations.

Abstract: A turbocharger includes a cylindrical wall and a non-ferromagnetic compressor wheel within the cylindrical wall. The non-ferromagnetic compressor wheel has fins. A magnetoresistive sensor housing is threaded through the cylindrical wall and houses a permanent magnet and at least one magnetoresistor. The permanent magnet is positioned so as to induce eddy currents on the fins. The permanent magnet magnetically biases the magnetoresistor, and the magnetoresistor senses rotation of the non-ferromagnetic compressor wheel.
