A water sport article is provided. The water sport article includes a joint formed between a first panel having a greater thickness than a second panel. The joint includes an overlapping interface between the first and second panels where one or more of adhesive bonding, blind stitching, and taping is used to attach the first and second panels at the overlapping interface.

This disclosure provides a protective diving system for isolating a diver from a hazardous diving environment. The protective diving system can include a dry suit system including a dry suit and a surface exhaust valve coupled to the dry suit, and a return-surface exhaust assembly configured to exhaust gas from the dry suit system to a breathable atmosphere outside of the diving environment of the diver. The surface exhaust valve is configured to receive gas from the dry suit and exhaust gas to the return-surface exhaust assembly without exhausting to the surrounding diving environment. The protective diving system can further include one or more chemically-resistant components, where the chemically-resistant components include a fluoroelastomer.

The present inventive concept relates to a sealing device (1) for garments to sealingly connect an annular layer (3) and a wearable layer (5) to the sealing device (1). The sealing device (1) comprises an annular base (10) having an inner annular wall portion (12) and an outer annular wall portion (14), a recess (30) at least partly defined by the inner annular wall portion (12) and the outer annular wall portion (14), and an annular sealing surface (40) for circumferentially and sealingly connecting the annular layer (3) to the annular base (10). The sealing device (1) further comprises an annular sealing body (60) adapted to be locked into the recess (30) to circumferentially and sealingly connect the wearable layer (5) between the annular base (10) and the annular sealing body (60). At least one of the inner annular wall portion (12) and the outer annular wall portion (14) is provided with a plurality of sections (50, 52) in the circumferential direction, each section having a stiffness different from a stiffness of a neighboring section.

A wrist-worn electromagnetic pulse generating wearable device for repelling great white sharks, tiger sharks, and bull sharks. i.e., the lethal shark breeds. The device includes an artificial intelligence/machine learning component (AI/ML) trained on a dataset including characteristics of the lethal shark breeds. A hydroactive sensor activates the device upon immersion in marine or fresh water. A signal generating component, responsive to AI/ML component, generates an ELF signal that radiates out to a 4 m area surrounding the user to repel shark attacks. Wave pulse characteristics, such as frequency, waveshape, and magnitude are determined by the AI/ML algorithm based on the detected shark breed. Antenna design based on fractal geometry (e.g., the T-square fractal, or the Sierpinski Triangle) generates an ideal isotropic radiation pattern. The wrist-mounted form factor of the inventive device offers improved performance over prior art devices.

A system that maintains a comfortable hand and/or feet temperature during the course of a water sports activity. Exhaled breath is fed to the inside of the sportsman's gloves and/or boots down a tube which runs along the inside of the wetsuit to take full advantage of the insulating properties of that wetsuit. Rubber moulding units at the rear neck wrists and/or ankles facilitate the tubing's entry and exit from the wetsuit without disturbing the watertight properties of that wetsuit. The rubber mouldings can either be built into the wetsuit itself or separate inserts to go between the sportsman's skin and the wetsuit seals at the neck wrists and ankles.

A convertible seal for a suit used in and around water includes a body having at least one of a collar, a sleeve or a pant leg that must be sealed to prevent water entry during use. The collar, sleeve or pant leg is equipped with a permanently attached seal configuration that has an operative position is in axial alignment with the collar, sleeve or pant leg and a stored position out of axial alignment with the collar, sleeve or pant leg.
