In some implementations, an angle sensor may receive a first x-component value and a first y-component value from a first set sensing elements and a second x-component value and a second y-component value from a second set of angle sensing elements. The angle sensor may perform a safety check including determining a first range of angles associated with a target object based on a relationship between a magnitude of the first x-component value and a magnitude of the first y-component value; determining a second range of angles associated with the target object based on a relationship between a magnitude of the second x-component value and a magnitude of the second y-component value; and determining whether the second range of angles is a subset of the first range of angles. The angle sensor may output an indication of a result of the safety check.

A disc brake assembly that includes a brake caliper, a retainer strap, and a sensor assembly. The retainer strap is mounted to the brake caliper and extends across a brake pad assembly. The sensor assembly is mounted to the retainer strap and generates a signal indicative of a position of the brake pad assembly.

A magnetoresistive sensor has a sensor plane in which the magnetoresistive sensor is sensitive to a magnetic field. The magnetoresistive sensor includes a reference layer having a reference magnetization that is fixed and that is aligned with an in-plane axis of the sensor plane; and a magnetic free layer disposed proximate to the reference layer, the magnetic free layer having a free layer magnetization aligned along an out-of-plane axis that is out-of-plane to the sensor plane. The free layer magnetization is configured to tilt away from the out-of-plane axis and towards the sensor plane in a presence of an external in-plane magnetic field.

The present disclosure provides a method of monitoring the magnetic field in which a magnetic sensor is operating in to ensure that the sensor is operating within its defined magnetic window. For example, the method uses the sensor output of either a multi-turn sensor, or some other magnetoresistive sensor that is being used in conjunction with the multi-turn sensor, for example, a magnetic single turn sensor or a second multi-turn sensor, to monitor the operating magnetic field.

A magnetic sensor device includes a switching region defined by a switching range and a variation range, the switching range being set in a stroke direction of a magnet generating a radial magnetic field and defined by a start position and an end position for switching of the state, and the variation range being set in a direction intersecting the stroke direction and being a range of variation in the position of the magnet, and a magnetic sensor including plural first divided elements that are formed by dividing a first circular magneto-resistive element and are consecutively rotated and rearranged around the switching region such that change in a magnetoresistance value due to the magnetic field of the magnet in the switching region increases from the start position to the end position.
