Patent ID: 6941883

Claim:
An assembled underwater module for an observer, wherein said observer is not under water pressure and able to breathe directly atmospheric air being introduced into, and removed out of, the submerged booth, by means of air conducting pipes; said assembled underwater module comprising: a floating buoy set with sufficient buoyant force to keep module stable and in equilibrium state under water; said floating buoy set being a station for introducing breathing air into said submerged booth and also a platform for operational and supportive devices including power generator, safety devices and communication systems; a piping system for supplying breathing air and running electrical cables to said submerged booth with said observer inside; weight blocks made with high density metal for additional weight; a submerged observation booth for lodging said observer, operating equipment for said booth and said weight blocks; ultrasonic sensors for proximity measurement and adjustment of distance of said submerged booth in vertical direction from waterbed floor; a booth-lid that can open and close for the observer to enter and exit the booth; light-poles and warning lights located on said floating buoy set for vessels in the vicinity; a roof to cover the buoy set platform and the equipment on board; wherein, said submerged booth wall being transparent for said observer to look through said submerged booth for a full 360° viewing angle; said submerged booth being in either a cylindrical shape with two half-spheres at both ends, or a spherical shape; and said floating buoy set, said piping system, said ultrasonic sensors and said submerged booth are designed for synchronous operation and coordination.
