  • Patent number: 10434728
    Abstract: Various automated fiber placement systems and methods are disclosed. The system can determine steerable paths for the application of a composite material over highly contoured surfaces. The system can determine when a course trajectory would violate a steering limitation (e.g., a maximum bendability of the composite material) and can adjust the trajectory to avoid such violations. The adjustment can create gaps between adjacent courses, which can have a generally flared peripheral shape. The system can fill such gaps with subsequent courses of the composite material. Thus, the system can automatically apply composite material to highly contoured surfaces while also avoiding violation of the steering limitations.

    Abstract: A cylindrical carbon fiber arrow shaft formed with an exterior surface having single or multiple outside diameters and formed with an axial bore having multiple interior diameters. In a preferred embodiment, the exterior surface of the arrow shaft has an increased external diameter at the nock end and tapers to a smaller external diameter at the tip end. The axial bore has an internal diameter at the nock end corresponding to standard arrows having external diameters of 0.295 inches and tapers to a smaller internal diameter at the tip end. Modifying the length, diameter, and wall thickness of the arrow shaft varies the stiffness of the arrow shaft along the length and shifts the center of gravity along the length of the arrow shaft and as well. Utilizing standard internal diameters, nock and tips may be attached without spacers or inserts, thereby decreasing weight of the arrow significantly.

  • Patent number: 8980034
    Abstract: A method for producing a fiber-reinforced plastic component is specified. In a first step, a positive arrangement is produced by fixing at least one reinforcement ready to be used on a positive core. In a second step, fibers are wound around the positive arrangement, concave regions of the positive arrangement that are formed by the reinforcement being spanned by the fibers. In a third step, the entire area of the fibers is pressed onto the positive arrangement in a negative mould. Finally, the component is cured in the negative mould following the introduction of a cross-linking plastic.

  • Patent number: 8922493
    Abstract: The present invention discloses one or more embodiments of a mobile device capable of automatic enablement of a rear-face data entry. In a preferred embodiment of the invention, the mobile device can automatically detect and determine that a rear-face data entry interface is either facing up or facing the user's line of sight, which prompts activation of the rear-face data interface for immediate enablement of data entry (e.g. typing). If the rear-face data entry interface is either facing down or away from the user's line of sight, the mobile device disables the rear-face data interface for data entry to minimize accidental and undesirable data entry via the rear-face data interface. The preferred embodiment of the invention also incorporates a primary frontal touch-screen display, a secondary rear touch-screen display, a QWERTY keyboard, and display elevation guards on both displays.

  • Patent number: 8858857
    Abstract: A method of fabricating a composite vessel encompassing rapid manufacturing that is applicable to composite hydrogen and other gas storage tanks, both for high-pressure cylinders, as well as low-pressure conformal tanks. The process of fabrication includes using a liner, of metal or plastic materials, over which a braided or developed preform is wrapped. The dry fiber wrapped liner is placed in a mold and resin injected into the cavity formed between the liner and the mold outer walls. The liner is flooded with heated and/or cooled pressurized fluid thus enabling complete and independent process control from within the liner for both the resin injection and the cure phases. Fiber placement control is determined through combined biaxial and triaxial braid/preform design, and by wrapping at controlled tension onto the supporting liner. Fiber tension control is further enhanced by the methodology of mold loading whereby tensioning forces are enacted during actual load and close.

  • Patent number: 8834658
    Abstract: A cylindrical carbon fiber arrow shaft formed with an increased external diameter of 0.380 inches. This arrow shaft is formed with an axial bore which has a first internal diameter throughout a substantial portion of the shaft length, and a second, smaller, internal diameter throughout the fletching end of the arrow. The second internal diameter corresponds to the internal diameter of standard arrows having external diameters of 0.295 inches. Using this standard internal diameter at the fletching-end of the arrow, standard nooks may be used without the need for any spacer or insert, thereby decreasing fletching-end weight significantly and providing for the proper and more desired location of the center of gravity forward on the arrow.
