CONTACTLESS SLIP RING SIGNAL COUPLER

摘要

An apparatus enables digital data to be sent between first (12b) and second (12a) components that rotationally move with respect to each other about an axis (19). A transmitter (40) mounted on the first component (12b) produces an output signal that has a pulse whenever the digital data makes a state transmission line (51) which is attached to the first component (12b) and extends about the axis (19). A receive transmission line (57) is attached to the other component (12a) and curves about the axis (19) adjacent to the transmit element (51). A circuit (60) produces a state transition in a digital output signal whenever an electrical signal from the receive transmission line (57) transcends a reference level.
