Operational Experiences with and Reasons for Removal of the Closed Circuit Television and Wetpot TV Camera Positioning Systems Installed in the NAVXDIVINGU Hyperbaric Complexes August 1968to June 1971.

摘要

In late 1968 a closed circuit televeision system was installed in the hyperbaric complexes at the Navy Experimental Diving Unit. The system used cameras mounted inside the hyperbaric chambers with external monitors and power supplies. The two cameras installed in the wetpots of the hyperbaric complexes were mounted on remotely controlled positioning systems capable of vertical movement and horizontal pan. The operational experiences with the closed circuit TV system and the wetpot TV camera positioners are described. Also described are the reasons why,in 1971,both systems were removed as a direct consequence of unreliable performance. (Author)
