Apparatuses and sensor systems are described with magnetoresistive sensor configurations. The method of detecting a displacement of a magnetic component includes monitoring, via a position sensor operating in a low-powered mode, a magnetic field emitted by a magnetic component. The monitored characteristics of the magnetic field vary based at least in part on a displacement of the magnetic component. The method also includes determining, via the position sensor, whether the monitored characteristics of the magnetic field satisfy an activation criteria. The method further includes increasing the power of the position sensor to a high-powered mode to determine the displacement of the magnetic component upon determining that the monitored characteristics of the magnetic field satisfy the activation criteria. Corresponding position sensing systems are also provided.

Methods, apparatuses, and systems for detecting a stray magnetic field are provided. An example apparatus may include a first magnetic sensor element at a first position relative to a magnetic field source to detect a target magnetic field emitted by the magnetic field source, a second magnetic sensor element at a second position relative to the magnetic field source to detect the target magnetic field emitted by the magnetic field source, and a processor element electronically coupled to the first magnetic sensor element and the second magnetic sensor element. In some examples, the processor element may be configured to: receive a first output from the first magnetic sensor element, receive a second output from the second magnetic sensor element, and detect the stray magnetic field interfering with the target magnetic field based at least in part on the first output and the second output.

Apparatuses and sensor systems are described with magnetoresistive sensor configurations. An example magnetoresistive sensor configuration includes an input feed that receives an electrical current, magnetic field detection circuitry in electrical communication with the input feed, and a feedback connection in electrical communication with the magnetic field detection circuitry and the input feed. The magnetic field detection circuitry transitions between a released state and an operated state in response to an external magnetic source. The configuration further includes an electrical storage element in electrical communication with the input feed that maintains a minimum operating voltage and current within the magnetoresistive sensor in an instance in which the magnetic field detection circuitry is operated.

A magneto-elastic torque sensor and system include a substrate and a magneto-elastic sensing component formed from or on the substrate. The magneto-elastic sensing component and the substrate together form a magneto-elastic torque sensor, which when subject to a stress associated with a torque, shifts a characteristic frequency thereof linearly in response to the torque, thereby inducing a pathway by which magneto-elastic energy is coupled to excite vibrations in a basal plane of the magneto-elastic sensor, thereby generating torque-based information based on a resonant frequency thereof.

A target is located between the engine and torque converter. One or more torque sensors can be integrated with one or more position sensors for detecting a position associated with the shaft, wherein the torque sensor(s) and the position sensor(s) are integrated into a single torque sensor package to thereby provide enhanced sensing of the target in association with a rotation of shaft during an actuation of the engine.
