Abstract (en)

[origin: WO2020041481A1] SCUBA diving equipment is composed of a heavy SCUBA pressure vessel, buoyancy compensation device and a heavy weight system. Together with a constricting exposure suit the current setup makes for a rather cumbersome system. Perfect buoyancy is a term used in SCUBA diving to describe the ability of the diver to maintain its vertical position in the water column. Doing so requires a thorough understanding of the governing physics principles as well as considerable practice time. Together, the cumbersome nature of standard SCUBA systems and the physical and mental requirements of operating said systems underwater are a commercial hurdle, preventing many individuals from entering the sport. The present invention provides systems that can significantly simplify both elements by allowing water to occupy some of the pressure vessel internal volume. Such a pressure vessel can be used as both the breathing gas source as well as a buoyancy control device, reducing or even eliminating the need for additional weights and a separate buoyancy compensation device. Embodiments of the present invention also comprise a control system and one or more sensors to provide an automatic buoyancy system.
