Pagination or Media Count:
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 ships hull and structure. The system consists of a portable, battery-powered transceiver unit capable of voice andor 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.
