摘要

A data transmission system (1) suitable for use with an impact transmissive body (4) and including a data transmitting device (6) having a reciprocable impact impeller head (3) for transmitting an encoded series of discrete mechanical impacts to a first surface of the impact transmissive body and a data receiving device (5) having an impact sensitive transducer (2) at a second surface of the impact transmissive body substantially opposite to its first surface for picking up vibrations resultant of the series of impacts.
