Abstract
A non-contacting rotary interface has a first core with a first pair of balanced transmission lines coupled to the first core and a second core moveable in relation to the first core with a second pair of balanced transmission lines coupled to the second core and configured to receive signals from the first pair of balanced transmission lines. The first pair of balanced transmission lines has a first transmit wire coupled to a termination point at a first end of the first transmit wire, a first transmitter coupled to the first transmit wire at a second end of the first transmit wire, a second transmit wire coupled to the termination point at a first end of the second transmit wire, and a second transmitter coupled to the second transmit wire at a second end of the second transmit wire. The balanced transmission lines may be electrical traces on a circuit board.
