Patent ID: 7889836

Claim:
A device for data transfer between two parts that are moving relative to one another while maintaining a slight distance between the two parts, comprising: a transmission device mounted on a first of said parts moving relative to one another, said transmission device comprising at least one transmission antenna connected to a signal transmitter; a reception device mounted on a second of said parts moving relative to one another, said reception device comprising at least one reception antenna connected with a signal receiver; at least one of said transmission antenna and said reception antenna being formed as a radio-frequency conductor and being arranged to cause signals fed into the transmission antenna from the signal transmitter to radiate from and be received by the reception antenna, via a non-galvanic transmission path, during at least one segment of the relative movement between the first and second moving parts, by capacitive coupling or inductive coupling across said non-galvanic transmission path; and at least one compensation device disposed between the signal transmitter and the signal receiver, said at least one compensation device counteracting signal distortion that occurs on said radio-frequency conductor due to propagation of said signal in said radio-frequency conductor.
