Abstract: The present invention relates to a rechargeable battery induction system. Specifically, an induction receiver, otherwise known as an induction coil, is connected to contact points of a rechargeable battery and utilized in an electric device requiring battery power. The induction receiver may thus be disposed within electric device housing or case, and may further include protective circuitry to prevent damage to the induction receiver when the battery is charged through a cord, plug or via other means. Methods of making and using the same are further provided.

Abstract: The present invention relates to methods of manufacturing articles comprising photochromic film, such as eyeshields, faceshields and lenses. Specifically, the methods of the present invention apply photochromic material to optically transparent thermoplastic material. Preferably, photochromic material is adhered to optically transparent thermoplastic material, such as polycarbonate, in a hot molding process.

Abstract: The present invention relates to methods of manufacturing laminated film and article made therefrom, such as eyeshields, faceshields and lenses. Specifically, the methods of the present invention laminate a film or plastic layer with a protective layer via an invention laminating process. The process may further be utilized to add materials, such as, for example, photochromic material to optically transparent material. Preferably, photochromic material is adhered to optically transparent material in a hot molding process.

Abstract: The present invention relates to an energy absorbing apparatus. Specifically, the apparatus comprises a first disk and a second disk atop the first disk, and a plurality of collapsible arms around the perimeter of the disks connecting the first disk and the second disk, and an elastic material disposed between at least two of the collapsible arms, wherein collapsing of the arms causes the elastic material to stretch, storing kinetic energy from the vertical direction as potential energy in the horizontal direction, wherein release of the potential energy from the elastic material causes the arms to return to an uncollapsed state. Systems utilizing the energy absorbing apparatus, methods of making and methods of using the same are further provided.

Abstract: The present invention relates to a stretchable fabric composite. Specifically, the fabric composite comprises a first layer comprising a stretchable fabric and a second layer comprising an elastic polymer; wherein the first layer and second layer are bonded together forming the fabric composite. The fabric composite is useful for constructing a garment or a compression article. A method of making the fabric composite is also provided.

Abstract: A firearm accessory mount may include multiple rails, each configured to mechanically couple one or more firearm accessories. Each rail may further have first and second electrically powered rail terminals for providing power to the firearm accessories when coupled to the rails. A switch may be associated with each rail that is selectively engageable to electrically couple or decouple power to that rail. Accordingly, each rail may be selectively powered to control operation of any firearm accessory mounted thereto.

Abstract: A method of manufacturing a cranial shock absorption system. The method is comprised of forming a first layer of elastomer, positioning a thin layer of material on top surface of elastomer such that the top surface is exposed around the entire exterior of the layer of material, allowing the first layer to partially set, positioning a tubular stem or valve on the first layer adjacent to the layer of material, forming a second layer of elastomer, allowing the first layer and second layer of elastomer to fully set around the thin layer of material, removing the thin layer of material from between the first and second layers of elastomer and then introducing a fluid into the chamber through the tubular stem.

Abstract: An electrical power system for crash helmets is described, including a storage cell configured to provide electrical energy to a power system, the storage cell being coupled to a processor and sealed within a lining of a helmet, and a pocket formed within the lining of the helmet, the pocket being configured to house the system. Also described is a connector configured to couple the storage cell to a power source, the power source being configured to charge the storage cell, and a distribution system configured to deliver electrical current from the storage cell to the power system.

Abstract: Techniques for footwear with integrated power systems are described, including a port configured to receive an electrical current, a power cell configured to store the electrical current from the port, a light source coupled to the power cell, a switch configured to control activation of the light source, the switch being coupled to the light source and the power cell, and a distribution system configured to provide a path to enable the electrical current to flow within the system.
