  • Underwater housing and pressure compensation method and apparatus
    Patent number: 5159366
    Abstract: A method and apparatus for protecting a camera or other apparatus from a water environment with a flexible, pressure compensated bag-like housing which is maintained at a slight positive pressure. The housing is larger than its contents to permit the contents to be moved relative to at least one wall to activate controls by frictional engagement between the wall and control during the relative movement. The housing may be configured as a merchandising container for the contents.

  • Pressure compensation method and apparatus for underwater equipment
    Patent number: 4980707
    Abstract: A method and apparatus for pressure compensating an under water housing which includes a tubular structure sealed around a hole in the housing dimensioned so that the mouth of an inflated balloon will form a secure seal there on so that the housing may be pressure compensated by blowing up the balloon and sealing the balloon mouth around the tube.

  • Pressure compensation method and apparatus for underwater equipment
    Patent number: 4947783
    Abstract: A method and apparatus for pressure compensating an underwater housing by blowing up a balloon and sealing the balloon mouth around a conduit to pneumatically connect the balloon to the interior of the housing. The balloon is configured to change its appearance either structurally or via indicia to provide a variable indication as to what depth it will provide compensating air. The indication varies in response to the amount the balloon stretches to accommodate the air forced into the balloon as it is blown up.
