Abstract
An apparatus for determining an amount of rotation of a rotatable component that rotates with respect to a stationary component. The apparatus includes a cable with a first end fixed to the rotatable component and a second end fixed to the stationary component. The cable, which supports a sensing element, is configured to wind or unwind when the rotatable component rotates with respect to the stationary component. The sensing element extends along a length of the cable and is configured to flex in response to the winding or unwinding of the cable. The sensing element has a resistance that changes in response to flexion of the sensing element. An evaluation circuit is connected to the sensing element and is configured to determine a value having a relation to the resistance and determine the amount of rotation based on the value.
