摘要:
A first stage pressure regulator is provided. The regulator includes a valve body having an inlet and an outlet coupled by a pressure chamber. A pressure compensation chamber fluidly communicates with the surrounding water. A valve member is slidably carried by the valve body between an open state in which fluid is permitted to flow between the inlet and outlet and a closed state in which fluid is prevented from flowing between the inlet and outlet. The valve member has an expansion head that is operably acted upon by the surrounding water within the pressure compensation chamber to bias the valve member toward the open state. The regulator includes an annular insulating bushing within the compensation chamber that covers a portion of the valve body defining a portion of the pressure compensation chamber to insulate the valve body from the water within the pressure compensation chamber.

A valve assembly and a regulator for use therein are disclosed. The valve assembly includes a valve poppet having a first end having a first face and a second end having a second face. The first face has a surface area smaller than the surface area of the second face. The second end of the valve poppet is received in a sealed chamber and a passage provides fluid communication between the inlet of the regulator and the chamber for allowing gas accumulating in the chamber to act on the second face for urging the valve poppet in the closed position without the use of a spring.

A diving computer (10) is provided. The diving computer (10) includes a computer (20) connected to a dot matrix screen (18) to display information concerning a dive. The computer has an interface (14) to an external personal computer (11) for reprogrammably configuring the information displayed on the screen (18). The user may customize the information on one or more views of the screen (18) in several ways. The user may select the desired information to be displayed, and may customize the size and placement of the information on one or more views. The diving computer (10) also has a number of pre-programmed displays that may be selected, each of which present different layouts and organizations of diving related information.

A quick release connector is provided for underwater diving equipment such as a weighting system for buoyancy control. The quick release connector includes a first connector portion which may be mounted to the apparel unit and a second connector portion which may be mounted to one or more weights. The second connector portion interfaces with the first connector portion includes a pivotable lock that can be actuated against a spring to decouple the two connector portions and allow for manual release of the weights.

A supplied air snorkeling system includes an air tank (10), at least one regulator (22) coupled to the air tank and including a mouthpiece through which air from the tank is provided and a supplied air snorkeling vest. The vest includes a back portion (44), a front portion (46), a head opening and a tank holder (59). The back portion (44) is configured to extend along a snorkeler's back when the vest is worn and includes at least one layer of floatation material (60). The front portion (46) is pivotally coupled to the back portion (44) and includes a main body (73) having at least one layer of floatation material and shoulder extensions (75) extending from the main body (73) to the back portion, The main body (73) is configured to extend laterally across the snorkeler's chest proximate to the snorkeler's clavicle and the across the snorkeler's sternum body. The head opening is formed at a juncture of the back portion (44) and the front portion(46). As a result, the front portion (46) may be pulled from behind the snorkeler's head and over the snorkeler's head as the head opening receives the snorkeler's head. The tank holder (59) is coupled to the back portion (44) and releasably secures the air tank to the back portion, A buoyancy compensator similar to the vest is also disclosed, except that the buoyancy compensator includes inflatable chambers in lieu of the flotation material.
摘要:
Rebreather, with a multifunctional mouthpiece with a closed circuit mode, an open circuit mode, an automatic diluent valve with an increased cracking pressure, an overpressure valve where by turning a barrel the modes can be selected and the automatic diluents valve and the overpressure valve get activated synchronously. Further said rebreather having a single piece counterlung, in which a CO 2 filter cartridge is inserted through an opening and placed in between inhale and exhale side of the counterlung, to achieve a double counterlung system. Rebreather which can be transformed into a backpack, to achieve good protection and enable easy transportation of the device even in the cabin of an airplane. Rebreather with a primary and a secondary head-up display, where the primary LED based head-up display is located on the mouthpiece and the secondary, OLED or LCD based head-up display is located on the frame of the divers mask, and the primary head-up display transmits dive relevant data via an optical link, preferable infrared of visible light, to the secondary head-up display.
摘要:
A sonar mapping system that includes a sonar transducer assembly configured for mounting on a watercraft, and a display configured to show a topographical chart of a body of water. The sonar mapping system further includes a processor coupled to the sonar transducer assembly and display. The processor is configured to create the topographical chart in real time, and to update the topographical chart in real time, based on sonar data provided by the sonar transducer assembly. The processor is configured to render the created or updated topographical chart on the display. The sonar mapping system has memory accessible by the processor and configured to store the topographical chart rendered by the processor, and to store the sonar data provided by the sonar transducer assembly. The sonar data includes information indicative of vegetation present on a lakebed, seabed, or riverbed surface, the information being displayed on the topographical chart.
