Patent attributes
An electrical rotary connection (15) comprising a first element (18) supported by a housing (16), a second element (19) supported by the housing, the first and second elements configured to rotate about a central axis (X) relative to each other at a rotary interface (20), the first element (18) comprising an input electrical lead (21), an electrical-to-optical E/O converter (22) having an optical source (23), and a transmitting lens (28), the second element (19) comprising a receiving lens (30) opposing the first element across the rotary interface, an optical-to-electrical O/E converter (32) having an optical receiver (33), and an output electrical lead (35), whereby electrical input received by the first element may be converted into light, the light may be transmitted on-axis across the rotary interface to the second element, and the light may be converted into an electrical output by the second element for transmission via the output electrical lead of the second element.
