Abstract: This invention provides new above knee (AK) and below the knee (BK) orthotic devices and implements specific manufacturing processes for the production of orthotic devices through the automated, computer controlled bi-axial and tri-axial braiding of orthotic devices, over a mold or mandrel made of carved foam, plaster material or wax that is a replica of the patient's limb, and is created by a Computer Aided Design (CAD) file controlling a Numerically Controlled (CNC) machine tool. This method of manufacture using aerospace fibers such as graphite or Kevlar, and high performance resins, is used to create a orthotic device which is stronger and lighter weight than conventionally manufactured orthotic devices. Braiding also allows incorporation of woven cloth, tapes and other reinforcements into the braiding process for added strength at selected areas. The method dramatically decreases the production time and cost of the relative to conventional methods.

Abstract: The present invention relates to standardizing the manufacture above-the-knee (AK) and below-the-knee (BK) prosthetic sockets and attached hardware using specially designs alignment jigs that can record position of components, with micro-encoders embedded in the jig, to quantify various degrees of freedom (rotations and translations) during integration of a temporary check socket or prosthesis. These records, together with a digital record of the shape of the truncated limb, in the form of a CAD file, can provide a complete digital record or “prescription” of the prosthesis. The digital record is then transferable to a central fabrication facility which uses a jig augmented with motors, drives systems, and encoders to robotically position and align fixtures and clamps to streamline integration and production of the prosthesis in a standardized manner.

Abstract: An extendable beam has compact slideable segments with angular extensions connected by cables which are tensioned to strengthen the beam when the beam is extended by sliding the segments. Restraining parts slide along tracks on neighboring segments. Short fixed length cables are connected between tips of extensions and diagonally between extension tips and segments are tensioned when hinged extensions are deployed. Other cables are paid out and tensioned, connecting tips of extensions on adjacent segments. Internal pulleys and beam extension cables simultaneously slide adjacent segments to extend the beam. An external crane and lock extend the beam serially.

Abstract: Launching payloads at high velocity uses high-pressure gas or combustion products for propulsion, with injection of high pressure gas at intervals along the path behind the payload projectile as it accelerates along the barrel of the launcher. An inner barrel has an interior diameter equal to the projectile diameter or sabot containing the projectile. An outer casing surrounds the inner barrel. Structures at intervals attach the outer casing and the inner barrel. An axial gas containment chamber (AGC) stores high pressure gas between the inner barrel wall, the outer casing wall, and enclosure bulkheads. Pressure-activated valves along the barrel sequentially release the high pressure gas contained in the AGC in to the barrel to create a continuously refreshed high energy pressure heads behind the projectile as it moves down the barrel. A frangible cover at the exit end of the barrel allows the barrel to be evacuated prior to launch. The launcher is rapidly recyclable.

Abstract: Solar generators have Fresnel lenses and spaced heat absorbers or photovoltaic cells for receiving focused solar rays. Heat is removed from their backs by boiling liquid in conical receivers. Pins or fins extend rearward into the receivers from the heat absorbers or photovoltaic cells. Liquid supply to the receivers is controlled by valves and floats or sensors. Tubes remove steam or vapor from the receivers for driving generators or for cooling photovoltaic cells. Hinged tubes which form the foldable support conduct the steam to generators and condense the vapor. Liquid is returned to a holding tank, is pumped to a distribution tank and is conducted by some of the structural tubes back to the valved receivers.

Abstract: A conformable battery wherein the outer casing has an upper face plate, a lower face plate, and at least one perimetric wall, and an interior of the battery comprising a grid of walls extending from the upper face plate to the lower face plate and connecting to the at least one perimetric wall, thereby dividing the interior of the battery into at least two compartments and increasing the battery's structural stiffness and ability to sustain increased internal pressure. Each compartment contains an electrochemically active plate stack, and a network of electrical conductors provides electrical connection between the plate stacks in each of the compartment. The battery may further comprise a reservoir containing an acid additive which, when released into each of the compartments, shifts the battery from a low power mode into a high power mode.

Abstract: The Conformable Battery encompasses a class of devices wherein the outer casing of the battery may be configured in a variety of shapes to fit specific applications including flat planar designs (circular, square, rectangular) and three-dimensional geometric shapes (e.g., curved plates, thin cylinders with hollow cores, other geometric shapes). The internal structure of the battery consists of multi-cell compartments where the walls of the compartments are bonded to the outer skin contributing to the batteries' structural stiffness, integrity, and ability to sustain moderate to high internal pressure, with enhanced ability to dissipate heat. The design is applicable to the patented Bimodal Battery concept (U.S. Pat. No. 6,187,471B1) as well as other battery design concepts.

Abstract: A winged hybrid airship (dynastat) combining the advantages of lighter-than-air (LTA) and heavier-than-air (HTA) aircrafts is disclosed. By combining the dynamic lift of low drag, high aspect ration airfoils (e.g., length over chord >10) with the static lift of low drag, laminar-airflow airships, a platform is formed which is capable of prolonged high altitude flight, maintaining station over a given point on the earth, carrying a payload of communications, reconnaissance or meteorological equipment. Solar collection cells and microwave antennas allow for recharging of on board batteries/fuel cells for powering both the airship and on board avionics computers and reconnaissance or meteorological equipment. An alternate embodiment, having strengthened structural members, is able to provide low altitude heavy cargo lift in remote regions regions or cross country transport of goods.

Abstract: The present invention offers a low cost, modular structure with a continuous, horizontal, rotatable spine supported on posts fixed to the ground, providing one axis of rotation for pointing solar collectors in the North-South direction and vertical roll axis bars mounted orthogonally to the spine providing an additional axis of rotation in the East-West direction. Push rods provide linear motion for control of any number of solar collector modules, with the linear motion being translated to rotary motion by pulleys and cables attached to wheels or arc segments mounted to the spine and roll axis bars. Thus, a whole array of solar collector modules can be driven by a single solar tracking device and two drive devices. Additionally, when arrayed in multiple rows of the number of solar collector modules controlled can be multiplied so that a “solar farm” covering a large area could be controlled by the single solar tracking device and a minimal number of drive devices.
