Claim 9:
10. An angle sensor, comprising:
a first angle measurement path to determine a first x-component value and a first y-component value based on sensor values from a first set sensing elements, wherein the first set of angle sensing elements are associated with a first measurement range;
a second angle measurement path to determine a second x-component value and a second y-component value based on sensor values from a second set of angle sensing elements, wherein the second set of angle sensing elements are associated with a second measurement range that is different from the first measurement range;
a safety path to perform a safety check, the safety path being configured to:
segment, based on an intersection of an x-component signal and a y-component signal associated with the first set of angle sensing elements, the first measurement range into a plurality of first segments;
segment, based on an intersection of an x-component signal and a y-component signal associated with the second set of angle sensing elements, the second measurement range into a plurality of second segments;
determine a first segment, of the plurality of first segments, corresponding to a first range of angles associated with a target object based on a relationship between the first x-component value and the first y-component value;
determine a second segment, of the plurality of second segments, corresponding to a second range of angles associated with the target object based on a relationship between the second x-component value and the second y-component value; and
determine whether the second range of angles is a subset of the first range of angles; and

an output component to provide, to a controller, an indication of a result of performing the safety check based on whether the second range of angles is a subset of the first range of angles, wherein the indication of the result of performing the safety check indicates whether a failure, an error, or a deactivation is associated with one or more of the first angle measurement path or the second angle measurement path, and wherein the controller performs one or more operations associated with controlling one or more of an electrical system or an electrical subsystem based on the indication.
