Abstract:
Methods and systems to provide breathing air to underwater divers in response to the divers' respiration at pressures less than 25 psi above atmospheric pressure during inspiration while delivering no or minimal air during exhalation, by controlling the actions of a pump during the time course of breathing. Methods and systems that sense a diver's need for breathing air, determine inhalation demand or exhalation state, and control the operation of a pump which delivers breathing gas to the diver via a tube. An integrated system for the same which incorporates at least an energy source, pump, air tube, breathing aperture, sensor, and logic processor is disclosed.
Abstract:
The invention concerns an underwater immersion installation (10) comprising at least one immersion pod connected to means (16, 18, 20) for lifting and lowering same, and an assembly of breathing and acoustic attachments borne by the pod (14) and separable therefrom when the pod is immersed, each breathing and acoustic attachment including a headgear mounted on a vest urged to be positioned on the chest of a user and being provided with a conduit supplying the headgear with air delivered from the surface and listening/communication means connected to complementary means.
Abstract:
The oxygen tank flotation device is a floating structure adapted for use in recreational water activities. The oxygen tank flotation device is adapted for use with respiratory equipment that is required for use during recreational water activities. The oxygen tank flotation device receives and stores respiratory equipment, such as an oxygen tank, in such a manner that the respiratory equipment will float when the oxygen tank flotation device is placed in a body of water. This arrangement allows the respiratory equipment to float near the user when the user is involved in recreational water activities. The oxygen tank flotation device comprises a vessel, a first float, and a second float.
Abstract:
An apparatus for preventing or minimizing decompression illness in a scuba diver, consisting of a first safety bar, at least one first cable attached to the first safety bar, and an oxygen delivery system. The first cable supports the first safety bar at a predetermined depth. The oxygen delivery system consists of an oxygen tank, an oxygen delivery line, a manifold attached to the oxygen delivery line, and a plurality of regulators attached to the manifold. When the oxygen delivery system will be used by only one scuba diver, the oxygen delivery line can be connected directly to a single regulator without the manifold. The first cable and oxygen tank are attached to a float, which is either secured to a boat or platform via a tether line or anchored to the sea floor. In an alternative embodiment, the first cable is attached directly to a boat or platform, and an oxygen supply is provided on the boat or platform. In another alternative embodiment, the apparatus further includes a second safety bar connected to the first safety bar by at least one second cable, which supports the second safety bar at a predetermined depth below the depth of the first safety bar. In yet another alternative embodiment, the apparatus further includes a plurality of safety bars connected in series to the second safety bar by a plurality of cables, which support the plurality of safety bars at predetermined depths below the depth of the second safety bar.
Abstract:
A muscle-powered diving equipment comprising a pump worn by the diver, which is operated by the diver's legs by means of a belt arrangement and foot loops attached thereto. When the diver's legs are extended, air is sucked in through a tube whose end is attached to a floating buoy. When the diver's legs are bent, the aspirated air is compressed by the pressure of the surrounding water and can be breathed in by the diver through a breathing tube. The exhaled air escapes through an expiration valve into the water.
Abstract:
A system is designed to increase diver safety in a high-risk environment containing one or more hazardous materials. The system includes chemically-hardened surface-supplied diving equipment designed to provide full environment isolation for the diver. The system also includes a dive helmet and a surface-return exhaust system, where the surface-return exhaust system includes a demand exhaust regulator that serves as a pressure-actuated valve to enable exhausting to a breathable atmosphere outside of a dive helmet instead of exhausting into the environment containing one or more hazardous materials. The system also includes retrofittable kits enabling the upgrading of contaminant-vulnerable materials of an existing dive helmet. The system also includes fluoroelastomeric materials and components to implement in a closed circuit dive system.
Abstract:
An umbilical system for sourcing and delivering within a flexible protective covering, a plurality of different breathing gasses, safety tether, a plurality of ancillary lines for remotely distributable, documentable, multidirectional, multi-format data/communications acquisition and delivery, personal/situational awareness and ancillary power sources for tool, accessory or device enervation, to a plurality of Users in an adverse environment.
Abstract:
A flotation device for diving, includes a u-shaped holster; a flotation piece, positioned inside the holster; and a connection harness, such that the connection harness can hold a tank with compressed breathing gas for diving, and a diver breathes underwater via a hose attached to the tank. The flotation device can further include adjustable straps, a carrying strap with a handle. The holster can further include an insertion aperture and at least one reinforcement strap. The flotation device can be a cylindrical elongated piece, including a pool noodle, and can be made from polyethylene foam. Also included is a flotation device for diving, including a u-shaped holster and a connection harness, such that a flotation piece can be positioned inside the holster.
Abstract:
A diver's station and umbilical cart neatly stores the umbilical cord and other various items used in hookah diving and has a frame made from various bars of aluminum stock. A set of wheels is pivotally attached to one end of the frame while a handle is attached to an opposing end. A seat is telescoping attached to the frame proximate the wheels. A first set of legs extends upwardly from the frame proximate the handle and has a first tray there atop, while a second set of legs extends upwardly from the frame between the first legs and the seat and has a second tray there atop. A telescoping post extends upwardly from the frame and passes through the second tray, the post having a T-brace there atop.
Abstract:
This flotation device for oxygen tanks is created to allow anyone dependent upon supplemental oxygen to utilize the pool or shallow water for recreation, exercise or therapy. Having their tank close to them in the pool or shallow waters, allows for more freedom of movement and safety for themselves and for others. The flotation device for oxygen tanks includes a base member flotation board with attachment members that include flotation tubes, straps, buckles and a grommet to secure the tank to the base member.
