Abstract
A gear assembly includes a first gear and a second gear. The first gear rotates about a first axis, and includes a first plurality of teeth and a first surface extending circumferentially and carried by the first plurality of teeth. The first surface is electrically conductive. The second gear rotates about a second axis and is operably connected to the first gear. The second gear includes an electrically conductive element, a second plurality of teeth, and a second surface extending circumferentially and carried by the second plurality of teeth. The second surface is electrically nonconductive. The electrically conductive element includes a plurality of feelers with each feeler projecting radially outward and into a respective tooth of the second plurality of teeth.
