A COMBINED DIGITAL DEPTH CONTROL AND RATE OF ASCENT CONTROL DEVICE FOR SCUBADIVING

摘要

A combined digital depth control and rate of ascent control device to be used by scuba divers. The device would automatically prevent the diver from exceeding a predetermined depth and prevent the diver from ascending at an excessively high rate. The device comprises a sealed housing attachable to the apparatus so as to be submerged in the water with the diver. The housing has an inlet connectable to the pressurized gas tank, an outlet connected to the inflatable buoyancy jacket, a control passageway between the inlet and outlet, being automatically displaced to open the passageway upon sensing the predetermined depth.
