Patent number: 11472523Abstract: 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.Type: GrantFiled: August 21, 2019Date of Patent: October 18, 2022Inventor: Aviad Cahana

An inlet valve, typically positioned conveniently on the top or the side of the mask may control the release of pressurized air into the mask. A pressure-sensitive outlet valve releases the pressurized air to force water from the mask. The outlet valve may be positioned on the lower portion of the mask or at a location where water is likely to collect.Type: GrantFiled: November 19, 2009Date of Patent: August 7, 2012Inventor: Phillip M.

Publication number: 20120128425Abstract: A buoyancy compensation device and method for a scuba diver or other underwater object, which decreases buoyancy by actively pumping air from a flexible bladder while the diver or object is in any orientation, said bladder having internally a manifold assembly providing access to pockets of air anywhere within the bladder. In addition, said device and method may be adapted for automatically diving, surfacing, or maintaining a predetermined water depth while the diver or object is in any orientation and while the diver's or object's orientation changes, including a sensor for measuring water depth, one or more control inputs for selecting a depth, and a controller unit that determines descent rate, ascent rate, or maintenance of a selected depth based on monitoring the water depth, the setting of the control inputs, and the diver's or objects previous habits and behavior.Type: ApplicationFiled: November 10, 2011Publication date: May 24, 2012Inventor: Jeffrey Alan Walck

Patent number: 8166968Abstract: A conjoined tube within a tube located inside a lower section of a snorkel designed to steer water droplets away from the snorkel diver's breathing path. The lower section of the snorkel has two valves. One is the scupper valve positioned at the lowest point of the inside tube. The scupper valve is a light duty valve or a low resistance one-way watertight passage intended to allow droplets of water to drain into the main reservoir. The outer tube lower section contains a reservoir for holding residual water that travels down to the bottom of the snorkel and is contained therein. During the normal clearing operation, the reservoir can be emptied and water will exit out of the lower section and into the surrounding water.Type: GrantFiled: November 6, 2006Date of Patent: May 1, 2012Assignee: Atomic Aquatics, LLCInventor: Dean R. Garraffa

Patent number: 8157479Abstract: A buoyancy adjustment device utilizes an inflation valve connected between the diver's breathing gas supply and a compartment to admit gas into the compartment to increase the diver's buoyancy. An exhaust valve connects between the compartment and the outside of the vest, to release gas from the compartment to the surrounding environment to decrease the diver's buoyancy. A hand-operated controller connected to the inflation valve, when caused to move from a neutral position to an inflation position, actuates the inflation valve and admits gas to the compartment. The hand-operated controller is also connected to the exhaust valve via a flexible pushrod so that, when caused to move from the neutral position to an exhaust position, actuates the exhaust valve and releases gas from the compartment. The flexible push rod is housed in a sleeve that is totally contained within the compartment.Type: GrantFiled: April 8, 2011Date of Patent: April 17, 2012Assignee: Aqua Lung America, Inc.Inventor: David B. Sullivan

Patent number: 8152413Abstract: An improved buoyancy compensation device having a lesser change in buoyancy with depth than conventional buoyancy compensation devices which use ambient pressure bladders is disclosed. The improved device comprises one or more elastic members that, throughout the working range of diving pressures and volumes, is always elastic and, when pressurized, maintains an internal air pressure that is always greater than the ambient pressure at any dive depth. The invention also relates to a method of providing a buoyancy compensation device with an elastic member having a lift versus depth characteristic that approaches the lift versus depth characteristic of a constant or fixed volume buoyancy compensation device.Type: GrantFiled: June 29, 2009Date of Patent: April 10, 2012Inventors: Lloyd A. Marks, David W. Weber

Publication number: 20110305520Abstract: An embodiment of a weight system for use with a buoyancy compensator device includes a rigid plate, a weight pouch attached to the rigid plate, and an indicator device fixedly interfaced with the rigid plate. The indicator device further includes a freely moving floatation device that floats within a restrained range upward from the rigid plate in response to the weight pouch being separate from the buoyancy compensator device.Type: ApplicationFiled: June 9, 2011Publication date: December 15, 2011Inventor: MATTHEW WEST
