The new buoyancy compensator has an air bladder system that is contained within the front lobes of the jacket that makes the jacket more streamlined and makes access to gear contained on the jacket much easier. Moreover, the streamlined nature of the compensator increases the stability of the user during entry and exit from the water.

Abstract: A gunn cut glove construction in which a pre-curvature at selected locations, preferably around the joints, in the fingers is achieved by sewing wedges of material into cut portions of the gunn section so that the shortened fingers and larger back sections easily meet at and can be joined without the need to gather or moccasin material resulting in the shape of the finger being such that it curves forward towards the palm section. Increased volume at the fingertips of a gunn cut construction glove is achieved by darting the palm side pieces of fingers proximate the fingertips. In addition, to reduce the inflexibility of gloves when curled into a fist, an elliptical piece is removed from the palm portion of the glove and the sides of the elliptical piece are sewn together along a seam.

Abstract: A strong, lightweight, impact resistant helmet system protects the wearer from impact injury and minimizes bodily injury to other players brought into contact therewith during blocking and tackling events. Weight reduction is achieved by reinforcing inner and outer surfaces of the helmet shell with long length, high strength fibers. Orientation of the fibers is such that the fiber lengths are aligned generally in the direction of tension and compression forces imposed on the helmet surface during impact. This reinforcement geometry permits use of a thin helmet shell. Efficient impact absorption by the helmet shell is accomplished by limiting the bend curvature produced at the impact location. The bend curvature reduction increases the contact area between the helmet shell and a pliable padded inner helmet made from energy absorbing polymeric foam disposed within the helmet shell in contact with its inner surface.

Abstract: Periscope Swim Goggles are swimmer's goggles with a periscope situated above the water line that projects the view that is ahead of the swimmer through a fiber optic cable to a viewer located on the goggle's eyepiece. Generally, an open-water swimmer using the free style or crawl stroke must occasionally sight on a landmark to swim toward. Periscope Swim Goggles would enable the swimmer to continually swim directly along the desired path without lifting the head for sighting. Conventional swimming goggles are typically comprised of two eyepieces contoured and gasketed for an air-tight fit around each eye socket and an elastic strap that wraps around the head holding the eyepieces tight to the face. In one embodiment of the invention, the periscope is positioned and secured at the back of the head by the elastic strap of the goggles. The fiber optic cable leaves the periscope and follows the elastic strap to the viewer which is mounted to the front of the eyepiece.
