Abstract:
1. A device for non-contacting transmission of electrical signals between relatively movable parts, comprising: a first part and a second part, one of said parts being movable relative to the other of said parts; a transmission module on said first part that emits differential electrical signals; a strip conductor pair on said first part and being supplied with said differential electrical signals omitted from said transmission module, said strip conductor pair comprising at least one component that reduces a common mode signal component in said strip conductor pair arising from said differential electrical signals in said strip conductor pair; a reception element on said second part at a gap from said strip conductor pair being in a coupled relationship with said strip conductor pair during movement of said one of said parts to receive signals radiated by said strip conductor pair dependent on said differential electrical signals in said strip conductor pair; and a reception module in communication with said reception element supplied with said signals received by said reception element.
