Provided is a timepiece mechanism (1, 1′) indicating information relating to the ambient pressure. The timepiece includes an ambient pressure measuring device that deforms mechanically due to ambient pressure variation. The device includes a first wheel assembly (31) kinematically linked to the ambient pressure measuring device that rotates under the effect of an ambient pressure variation and a measured pressure indicator mechanism (40) including a measured pressure indicator organ. The device also includes a second wheel assembly (33) configured to be in uncouplable connection with the first wheel assembly (31) so thesecond wheel assembly (33) is rotated by the first wheel assembly (31) under the effect of the pressure variation. Also included is a zero-reset mechanism (100) to position the measured pressure indicator organ (44) in a reference position by uncoupling the second wheel assembly (33) from the first wheel assembly (31).

The diver's floating marker assembly is a marker buoy. The diver's floating marker assembly is configured for use in water. The diver's floating marker assembly is a safety device that marks an area in the water where one or more divers are operating. The diver's floating marker assembly is comprises a marker structure, a reel structure, and a tether. The tether attaches to the marker structure. The marker structure is a buoyant structure that visibly marks the area in the water where one or more divers are operating. The reel structure stores, pays out, and retracts the tether. The tether is paid out and retracted by the one or more divers while underneath the water. The use of the reel structure allows the position of the marker structure to be set by the one or more divers while underneath the water.

The invention is directed to an apparatus that allows users to dry, wash, and store their wetsuits and wetsuit accessories. The apparatus includes a receptacle with an interior sized and shaped to hold a wetsuit and a user's accessories. The receptacle comprises a drain configured on one side to dispose of any accumulated water and debris. The interior of the receptacle includes joints that allow a collapsible rack to extend or retract as desired by the user. Thus, a user can wash a wetsuit in the device reservoir, then hang the wetsuit from the drying rack for complete drying. The rack can also be folded to store the wetsuit and any desired accessories (gloves, shoes, etc.) until they are needed.

A therapeutic gas source and cart and methods thereof for use with a therapeutic gas delivery system is disclosed. The therapeutic gas source may include a cylinder operable to contain a therapeutic gas that includes a body and a gas source valve body. In some examples, the gas source valve body has a valve and a coupling member.

An underwater diving light with efficient waterproof performance includes a top cover, a bottom cover, a light-emitting assembly and a special-shaped light-transmitting seal. A first installation groove is formed in the top cover. A second installation groove is formed in the bottom cover. The special-shaped light-transmitting seal includes a light-transmitting waterproof part, a first installation part and a second installation part. The first installation part, the light-transmitting waterproof part and the second installation part are all annular and connected in sequence. The top cover and the bottom cover are movably connected to form a light housing. The light-emitting assembly is arranged in the light housing. The underwater diving light has the advantages of strong waterproof and moisture-proof performance, diversified luminous forms and a dazzling effect.

A tablet-like device is configured to have a slightly negative buoyancy and to hold a sheet of waterproof synthetic paper, or another removable, waterproof recording sheet, onto which notes or messages or sketches can be recorded via a writing implement, in an underwater or marine environment, or another extreme or severe environment.

The invention relates to a method for constructing and/or manufacturing a water sports device (2) which has a modular structure comprising a floating body (4). The modules can be connected together via interfaces and are connected during operation. In particular, the invention relates to a method for constructing and/or manufacturing a foilboard or driver propulsion vehicle, wherein a server device is provided, and a program-controlled input interface is provided for user-defined inputs on a terminal (5), in particular a mobile terminal, which is arranged at a distance from the server device in particular. The modules are imaged in a computer program of the server device and/or of the terminal (5), and at least one outer contour of the floating body (4) of the water sports device (2) can be, in particular, freely defined by the user. On the basis of the outer contour of the floating body (4) defined in the program, automated manufacturing information is produced, and the floating body (4) manufactured according to the production information can be combined with another module, in particular multiple other modules, to produce the water sports device (2). The invention also

The present invention is a multi-functional dive tool designed for use by underwater or scuba divers, in particular divers that do so in rivers. The tool is a handheld metal spike designed to be utilized as a personal anchor or stabilizer when diving in water subject to strong currents. The tool has a pointed end to assist in pushing the spike into the river, ocean or lake bed. Unlike the prior art, the dive spike is constructed of materials with sufficient strength and weight that it can anchor the diver. The tool may also be used for a stand for cameras or lights, an anchor or pivot point for search lines, or an animal deterrent among other uses.
