Claim 17:
18. A system comprising:
a swivel assembly having a longitudinal axis and comprising:
an upper portion;
a lower portion that is rotationally coupled to the upper portion, wherein the lower portion has a connector configured to securely engage a cable, wherein the lower portion is configured to remain in electrical communication with the upper portion as the lower portion rotates with respect to the upper portion;
a motor disposed between the upper portion and the lower portion and configured to selectively rotate the lower portion;
a sensor that is configured to detect torsion in the cable; and
a controller in communication with the sensor and the motor, wherein, upon receiving a signal from the sensor indicating a threshold torsion in the cable, the controller is configured to cause the motor to rotate in a direction corresponding to a direction of the torsion in the cable; and

a computing device comprising a memory in communication with at least one processor, wherein the memory comprises instructions that, when executed, cause the at least one processor to perform a method comprising:
storing in the memory at least one metric selected from the group consisting of: a number of rotations, a number of rotations in a first select duration, a frequency of motor movements, a frequency of motor movements in a second select duration, a number of motor movements comprising a change in direction, a number of motor movements in a second select duration comprising a change in direction, a duration of constant movement, and a log of motor movements and the corresponding time of the motor movements.
