Abstract: A shock absorbing cap provides shock abortion in the space between the interior of a traditional safety helmet and the head of the wearer. The cap has a first region next to the scalp which is made of 100% knitted cotton for comfort and the absorption of sweat. A second region is made of 100% wool fleece braided fiber bundles that extend alternately in longitudinal and lateral directions sufficiently to nearly fill the space. The outermost region is made of one or more layers of braided 100% carbon fiber bundles, which run the opposite direction of the last wool lock. In an alternative, the first region is used but the second region completely fills the space with woven aramid and carbon fiber squares laid on top of each other and sewn together. The uppermost portion is laser cut for a tight but comfortable fit under the helmet.

Abstract: A structure, e.g., a shock absorbing cap, provides additional force or shock abortion between the interior of a traditional safety helmet and the head of the wearer. As a result, there is no need to change the helmets currently in use today. The cap has a first region, which is next to the scalp and is typically made of 100% knitted cotton. A second region is typically made of 100% wool fleece braided fiber bundles or locks that extend alternately in longitudinal and lateral directions. A sufficient number of layers of the knitted cotton bundles is provided to principally fill the gap between the head of each wearer and the interior of the helmet. This layer is the main shock absorbing element. The outermost region is typically made of one or more layers of braided 100% carbon fiber bundles, which run the opposite direction of the last wool lock. This carbon fiber bundle region helps to retain the structure of the cape.

Abstract: A jet engine intake guard includes an engine sleeve located within the nacelle of the engine; a primary deflection screen located at a front portion of the sleeve and having a first circular frame formed of a tubular fabric member and a plurality of fiber yarn strings disposed across the diameter of the primary frame and attached to one another in a tri-axel weave pattern. The guard also includes a secondary deflection screen located behind the primary deflection screen in the direction of air flow through the engine and having a second circular frame formed of a tubular fabric member and a plurality of fiber yarn strings disposed across the secondary frame and attached to one another in a tri-axel weave pattern. The guard further includes a capture basket located between the primary and secondary deflection screens. The capture basket has a first wall located toward the primary deflection screen, a center portion and a second wall located toward the secondary deflection screen.
