A dive mask including an ultrasonic communication system and an alert subsystem to measure the distance between two dive masks and alert divers if they have moved apart and exceeded a setpoint range. An illuminating edge or indicator light including at least one LED will illuminate to notify the divers they have moved apart and exceeded the setpoint range. The dive mask includes a danger function the divers may trigger to notify each other of potential danger. The dive mask includes a function to illuminate the at least one LED if the battery level in either dive mask is low.

An assembly includes a mask, a support piece, a filler piece and a mount piece. The mask has a frame that includes a right lens frame attached to a left lens frame by a bridge that supports a nosepiece, the frame further including a top surface and a connection region that is cut out from the top surface of the frame at the location of the bridge. The support piece is seated inside the connection region. The filler piece is seated inside the connection region and secured inside the connection region by the support piece. The mount piece has a bottom section, and a mount support extending vertically from the bottom section to receive a camera mount. The bottom section is seated inside the connection region and secured inside the connection region by the support piece when the mount piece is secured to the connection region.

A dive mask provides underwater images and includes: a transparent lens; a frame; a strap arrangement; a water-proof housing; a camera; and batteries. A first portion of the frame receives the transparent lens, and a second portion mounts to a wearer's face. The strap arrangement secures the frame to the wearer's head. The water-proof housing is secured within the frame, with a least a portion thereof being sealed against a portion of the transparent lens. The camera is positioned within the water proof enclosure, and include a shutter button that may be depressed to capture still images or video recordings. The batteries are positioned in the water-proof housing and power the camera. A water proof port permits recharging of the batteries. A waterproof pouch with a re-sealable waterproof closure is releasably secured to one strap using a lanyard, and stores the user's personal belongings while diving.

A snorkel mouthpiece assembly, including a main body, a mouthpiece, a connecting component and an accessory, is provided. The mouthpiece is connected to the main body. The connecting component includes a connecting portion and a fixing portion opposite to the connecting portion. The connecting portion is detachably connected to the main body, and the accessory is connected to the fixing portion. In this way, the snorkel mouthpiece assembly could be equipped with a variety of accessories during water or diving activities.

A wearable safety system for either diving, harsh or anoxic environments, or for individuals at high risk for respiratory and/or cardiac failure is disclosed. The wearable safety system includes biometric monitoring and provides cardiac and/or respiratory support in the event that the wearer experiences cardiac and/or respiratory failure. There are different configurations of the wearable safety system designed to work with different use cases, and to provide different levels of protection. In the case of diving, the wearable safety system additionally utilizes data collected by the dive computer to advise a rescue diver as to the best course of action in managing an unconscious diver's ascent and can also inflate the diver's buoyancy control device (BCD) or onboard personal flotation device.

The invention relates to a diving mask (10) comprising a telecommunication system (190) configured to allow the establishment of a one-way or two-way light communication and, more specifically, using a Li-Fi-type communication protocol. For this purpose, the telecommunication system (190) comprises a light communication module (150) comprising a light source (151) configured to emit light signals in a plurality of directions around the diving mask (10), and an electronic control card (156) in order to control the light source (151) and modulate the amplitude of the light signal according to an electronic signal encoded by said electronic control card (156). The invention also relates to an underwater communication method (200).
