Abstract: A plurality of optical transmission sources provide data communication from a transmitting module to a common detector cooperative with a receiving module, the modules being subject to relative rotation about a shared axis. The detector can be located on the shared axis, each of the sources directing a beam onto the detector regardless of relative module orientation, and/or the light can be diffused, so that it is detected regardless of source and detector placement and relative module orientations. Transmissions can be distinguished according to synchronized timing, differing optical frequencies, differing baud rates, and/or differing circular polarizations. The detector can split the light into a plurality of beams which pass through different optical filters and are thereby distinguished. Cut-off circuits can prevent failed sources from transmitting. A diffused second light source and a second plurality of detectors can provide reverse communication from the receiving module to the transmitting module.

This is achieved through embodiments of the joint in spite of the separate optical channels involved sharing the same central axis to allow for data transfer between moving and stationary joint components.

Abstract: Light emitting diodes are placed side by side at a front end of the remote control transmitter in a manner that their maximum radiation directions, i.e. radiation directions each giving a maximum radiation intensity, are each inclined at an angle within a range no larger than 5 degrees outwardly of the remote control transmitter 1 and symmetrically with respect to a bisector of a line segment which connects center points of the light emitting diodes. The inclination, within a range no larger than 5 degrees, of each of the light emitting diodes used as light sources for remote control does not cause significant reduction in the radiation intensity. Accordingly, it is possible to widen the transmittable angle within a range no larger than 10 degrees without significantly reducing the radiation intensity at a central portion of the radiation range.
