摘要

Data, signals and/or power is transferred from a fixed device having a transfer unit (14), intermediate member (25), coupling loop (16), coupling unit (15) and antenna (17) all arranged on fixed plate (13), to a moveable device having corresponding transfer unit (20) and antenna (21). The loop (16) passes through openings in unit (20).
