Technology Status: Damage Control Hull Communications (DC HULLCOM). Part 1. Advanced Development Model

Abstract

A noninterruptible and survivable damage control communications system (DC HULLCOM) has been developed that uses ultrasonic energy to communicate voice and casualty data through the ship's hull and structure. The system consists of a portable, battery-powered transceiver unit capable of voice and/or data communications; an acoustic transducer with clamp attachment; and a headset and Voice-Ducer (bone-conduction microphone and earphone) with cable assemblies. The system can be interfaced to the hull-mounted transceiver via a cable or an electromagnetic link from the hand-hold data entry and display unit. An Advanced Development Model of the system has been built and tested to demonstrate recent improvements in the system and is described in this report.
