Abstract:
Dive computers in accordance with embodiments of the invention are disclosed that store information concerning a dive site. The stored information can be accessed during the dive to provide information concerning such things as points of interest and/or hazards. One embodiment of the invention includes a processor, memory connected to the processor, a pressure transducer connected to the processor and configured to measure depth, and a display connected to the processor. In addition, the memory contains factual information concerning a dive site, and the processor is configured to display at least a portion of the stored factual information concerning the dive site via the display.
Abstract:
A diving apparatus for a diver underwater includes a portable habitat in which a breathable environment is maintained underwater. The habitat has a collapsible envelope. The collapsible envelope takes shape through inflation to an expanded state underwater. The habitat has a modular payload which removably attaches to the envelope underwater. The habitat has a seat on which a diver can sit while the habitat is underwater. The modular payload has a breathable gas source to provide breathable gas for the diver to breathe in the habitat and a carbon dioxide scrubber which removes carbon dioxide from the environment when the habitat is underwater. The apparatus has an anchor mechanism attached to the habitat to maintain the habitat at a desired depth underwater. A method for a diver to dive underwater. A system for supporting a diver underwater. A diving apparatus having a propulsion unit. An apparatus for a user in outer space or on another planet.
Abstract:
A dive computer system that utilizes a direct skin temperature measurement is provided. The dive computer system includes a measurement device that includes a temperature sensor and is attached to a strap. The strap is placed around a diver's chest and configured to measure the diver's skin temperature. The skin temperature is wirelessly transmitted to a dive computer that utilizes a dive algorithm to determine compartment inert gas saturation and desaturation. The dive algorithm determines an updated skin perfusion factor that is in turn utilized to determine an updated half time for the skin compartment for inert gas desaturation and a pressure tolerance for the skin compartment for inert gas saturation.

Abstract:
A diving computer has a housing in which electronic components, at least one diving data display means and an electricity source are disposed water-tightly. Furthermore there are means, accessible from the outside, for connecting the energy source to the electronic elements. The diving data display means is preferably a liquid crystal display module with an integrated background illumination that can be switched on and off. For switching on and off this said illumination, an acceleration sensor and an electronic circuit are mounted in the diving computer. These last-mentioned parts have the effect that the illumination can be switched on or off by merely knocking on the diving computer or hitting the latter against another object. This is a procedure which can also be done underwater easily and safely, using just one hand, despite relatively thick diving gloves.
Abstract:
The present invention is aimed to propose a method for minimizing erroneous shift to a water depth measurement mode by judging whether shift to a water depth measurement mode is caused by normal operation or erroneous detection and for automatically getting out of the water depth measurement mode even in the case of erroneous shift to the water depth measurement mode. Instantaneous shift to a water depth measurement mode is prevented when the water depth judging circuit 5 judges that a water depth value Ddpt from the measurement arithmetic processing circuit exceeds a predetermined value and that the water detection switch 6 detects no water contact, and a time information display mode is automatically returned even in the case of erroneous shift to a water depth measurement mode. Instantaneous shift to a water depth measurement mode is prevented when the water detection switch is on under conditions other than diving, and an original mode is automatically returned by judging the situation precisely even in the case of unexpected shift to a water depth measurement mode.
Abstract:
A flexible hyperbaric chamber includes a flexible air tight fabric vessel equipped with one opening at one or each end. A mobile door is provided for closing the fabric vessel. A metallic shield is provided adjacent to the opening outside the fabric vessel, the metallic shield defines a support into which the mobile door latches. A metallic collar is provided adjacent to the opening inside the fabric vessel. The metallic shield and the metallic collar cooperate to define a vice device for holding fabric of the fabric vessel. The fabric of the flexible fabric vessel is inserted into the vice device and this is tightened by a series of bolts with a predetermined torque. A flexible containment cage made by flat textile straps is provided. The straps are arranged in a discrete number of radial rings and a discrete number of longitudinal members, each intersection of radial rings and longitudinal members being fixed together to guarantee the consistency of the geometry of the cage. The flexible vessel equipped with the metallic shield and the metallic collar is inserted and contained within the cage.
Abstract:
The expansion valve unit, coupled to a lever of a diaphragm by means of a rod unit extending through the internal cavity of the housing, includes heat exchange with the surrounding medium, a rod support at the end of the rod unit opposite the valve unit, being also advantageously associated with a heat exchange unit so as to prevent icing, under the effect of expansion of the breathing gas into the housing, of the mechanical control train of the valve unit, in case of use in a cold surrounding medium.
Abstract:
A small-sized electronic device with depth gauge includes a pressure sensor for measuring a present water pressure and outputting a pressure value. A memory stores the pressure data. A dive time measuring circuit measures a dive time interval. A mean depth calculator receives the pressure data and dive time interval and in response thereto outputs a mean depth value which is displayed on the device.
