Diver{3 s pressurized equipment housings

A diver has a gaseous life support system that delivers breathing air to the diver's face that automatically is maintained at approximately the hydrostatic pressure of the water depth in which he is situated. Secured to the diver's body, for example, to his helmet, are equipment housings for cameras, electric lights, magnetometers, or other instruments. Conduits connect these instrument housings to the atmosphere breathed by the diver so that they are pressurized at approximately the hydrostatic pressure, that would otherwise crush them. Not only can the housings be lightly constructed, because of this absence of crushing forces, but the conduit connections are short and close to the diver's body so that they will not become entangled as the diver works. Electric control wires may pass through the pressurizing conduits.

Plano-convex lens system for underwater diving mask

An underwater diving mask comprising a face piece formed of suitable material so as to substantially conform to the contour of a diver's face, and a strap for releasably securing the face piece against the diver's face. The face piece has at least one opening formed in the forward part thereof for receiving a lens therein. The lens has an inner surface that is substantially flat (i.e. planar), and an outer surface that is slightly convex to thereby compensate for the magnification problem caused by the different indices of refraction between water and air. Preferably, the diopter value of the convex outer surface of the lens is between 0 and 1.0 so as to remove the lens from the domain of corrective lenses. A secondary corrective lens can, however, be affixed to the planar inner surface of the lens for those divers who would otherwise require corrective lenses. The lens is optionally treated to inhibit fogging, to reduce the amount of light reflected off the lens, to provide enhanced contrast imaging, and to protect divers from dangerous underwater radiation emissions.

Panoramic diving mask

Panoramic diving mask including at least one transparent, rigid front screen (11) fastened in a leaktight manner to an elastically deformable part called a "skirt", all being held by means of a rigid frame intended to be placed on a diver's face by means of a strap. The mask is composed of two convergent menisci (6) each formed from two faces: - the first, outer face is convex, - the second, inner face is concave, and the outer radius of curvature (a) is smaller than the inner radius of curvature (A) so that the field of vision of the said mask is enlarged and makes it possible to minimize the distortions in an aquatic environment compared with a flat-lens mask. Application to diving masks.
