Abstract:
1. A non-transitory computer readable medium having stored thereon a plurality of instructions comprising: instructions to generate a signal that causes a first current to flow in an electrical circuit in a first sensor element, wherein a first electromagnetic field is generated in response to the signal, and wherein the first sensor element is disposed proximate a second sensor element without physically contacting the second sensor element; instructions to sense a second electromagnetic field in a sensing circuit in the first sensor element, wherein the second electromagnetic field is generated in response to a second current flowing through a resonant circuit on the second sensor element, wherein the second current is generated in response to the first electromagnetic field, and wherein the second sensor element is disposed on a rotary member that is configured to be rotated about an axis Y by a shaft configured to pass through the rotary member along the axis Y at a value X; and instructions to determine the value X in response to the second electromagnetic field and in response to a value Z associated with the rotation of the rotary member about the axis Y.
