Abstract
A rotating capacitive data link system includes a first body rotatable relative to a second body. The first body has one or multiple circular signal transmission lines with multiple transmission line segments. The second body has multiple circular arranged sets of receiving couplers with multiple receiving couplers. Each of the sets of receiving couplers matches to one of the circular signal transmission lines, such that depending on the relative rotational position or angle between the first body and the second body multiple capacitively coupled paths between the transmission line segments and the receiving couplers of a matching set of receiving couplers exist. A receive signal processor is provided to generate a detailed error or status matrix of transmission errors.
