Abstract
A conductive slip ring system functions to transfer information electrically between a moving frame and a stationary frame. The conductive slip ring system includes a conductive transmission line and a conductive probe. The conductive transmission line is attached to the stationary frame or the moving frame. The conductive transmission line includes a first portion and a second portion. The first portion includes a first end and a second end. The first end of the first portion is coupled to a first terminator. The second end of the first portion is coupled to a signal source through a first reflection path impedance matching resistor. The second portion includes a first end and a second end. The first end of the second portion is coupled to a second terminator and the second end of the second portion is coupled to the signal source through a second reflection path impedance matching resistor. The second end of the first portion and the second end of the second portion are coupled together by a third reflection path impedance matching resistor. The conductive probe is attached to the moving frame or the stationary frame. The conductive probe contacts the conductive transmission line…
