Separated eye and orinasal pockets cut mask dead space, lowering CO2 buildup while maintaining sealing and breathing comfort.
Higher-friction inner surfaces and a thicker elastic edge help a silicone swim cap stay in place while fitting varied head shapes and hair.
A rotating cam elastically deforms the inner frame so diving mask lenses can be removed easily without damage while preserving watertight sealing.
Variable-thickness curved goggle lenses reduce underwater image dilation and horizontal distortion while preserving wide panoramic vision.
A bulbous stretchable cap with an elastic seal keeps locs, braids, and afros dry while accommodating high hair volume during swimming.
A rotating cam elastically deforms the inner frame so diving mask lenses can be assembled or removed without high force, damage, or finger injury.
A detachable front frame and embedded viewing windows keep this water sports mask compact, watertight, and easier to use with lower internal volume.
Separated eye and orinasal pockets with one-way valves cut dead space and lower CO2 buildup in a full-face snorkel mask.
Visual light sequences on strength equipment guide exercise phases and cadence when mental time tracking breaks down under effort and distraction.
Segmented eye and orinasal pockets reduce mask dead space, while pivot check valves direct intake and exhaust air to limit carbon dioxide buildup.
This case uses cylindrical and spherical lens zones with varied thickness to widen underwater vision while limiting image distortion.
Asymmetrical elastic cap eliminates wrinkles and covers ears, using localized cushioning to reduce head injury risk during collisions.
Flexible pleats in an elongated concavity accommodate voluminous hair while a draw cord sleeve establishes a water-tight seal against leakage.
A diving mask uses a flexible nasal partition to separate breathing chambers and enable natural nose and mouth respiration.
Distributed openings in a rigid shell allow water ingress to reduce buoyancy and drag, enabling easier surface penetration while maintaining impact protection.
Segmented compartments contain long hair while inflatable chambers provide buoyancy to resolve compression and fit issues.
Co-molding thermoplastic elastomers with varying Shore A hardness creates a unified structure that eliminates glass fragility while maintaining stiffness.
An integrated swim cap combines a respirator with a Bluetooth audio system, enabling voice communication without lifting the head out of water.
