Classification: CPC A  G | IPC A  G

Claim 10:
11. The swivel assembly of claim 1, wherein the sensor is a torque sensor comprising:
a pivot body that is pivotably coupled to the lower portion of the swivel about a pivot axis and is configured to be coupled to the cable so that torsion of the cable applies a torque to the pivot body that causes pivoting of the pivot body with respect to the lower portion of the swivel, wherein the pivot body comprises a radially extending surface that extends radially outwardly relative to the pivot axis;
a spring that is configured to bias the pivot body to a neutral position with respect to the lower portion of the swivel;
first and second electro-optical sensors that are radially spaced from the pivot axis of the pivot body and in respective angular positions with respect to the pivot body, wherein upon the pivot body pivoting a first threshold angular distance in a first direction from the neutral position, the radially-extending surface of the pivot body is configured to effect a change of state in the first electro-optical sensor, and wherein upon the pivot body pivoting a second threshold angular distance in an opposing second direction from the neutral position, the radially-extending surface of the pivot body is configured to effect a change of state in the second electro-optical sensor.
