Patent ID: 6937787

Claim:
Device for the transmitting of optical signals between a first device and a second device, both devices being rotatable relative to each other, comprising: at least one optical transmitter attached to said first device for emission of optical signals; at least one optical receiver attached to said second device for receiving said optical signals; at least one optical medium, preferably a light guide for transferring or guiding said optical signals; wherein said optical transmitters or receivers are arranged so that at any time at least one of said optical transmitters is connected via one of said optical media to at least one of said optical receivers; and wherein the total of the numbers of optical transmitters and optical receivers amounts to at least three and that the sense of rotation between said first device and said second device is equal to the sense of the direction of propagation of said optical signals, and that at least one switching unit is provided that selects optionally one of a plurality of optical transmitters or one of a plurality of optical receivers in such a way that precisely one optical transmitter and one optical receiver is activated at one time for transmission between said first device and said second device and that means are provided in said second unit for deleting of multiply transmitted data.
