ABSTRACT:
An acoustic data link using the I-beam frame of a structure. The use of sl or aluminum framing permits a structure such as a ship to suffer damage in one section without loss of communication between sections. A universal asynchronous receive and transmit circuit converts data to be sent into a binary code which is inputted to the frame by a transducer. At a different location, a similar transducer receives the signal which is then converted back into an electrical signal.
