Patent attributes
A method and apparatus for transmitting signals. An apparatus comprises a first cylinder, a second cylinder, a third cylinder, and a fourth cylinder. A first cylinder has a first number of conductive segments. The second cylinder has a second number of conductive segments. The first cylinder is located inside the second cylinder such that the first conductive segments remain in communication with corresponding ones of the second conductive segments during rotation of the first and second cylinders relative to each other. The third cylinder has a third number of conductive segments. The second cylinder is located inside of the third cylinder. The fourth cylinder has a fourth number of conductive segments. The third cylinder is located inside the fourth cylinder such that the third conductive segments remain in communication with corresponding ones of the fourth conductive segments during rotation of the third and fourth cylinders.
