  • METHODS FOR ASSAYING PERCENTAGE OF GLYCATED HEMOGLOBIN
    Publication number: 20110250627
    Abstract: The invention provides enzymatic methods for direct determination of percentage of glycated hemoglobin in blood samples without the need of a separated measurement of total hemoglobin content in blood samples. The methods utilizes one or two different types of oxidizing agents which selectively oxidize low-molecular weight reducing substances and high-molecular weight (mainly hemoglobin) reducing substances in blood samples, coupled with enzymatic reactions catalyzed by proteases, fructosyl amino acid oxidase. The amount of hydrogen peroxide generated in the reaction is measured for determination of percentage of glycated hemoglobin in blood samples. The invention provides kits for performing the methods of the invention.

  • BAR ARMOR SYSTEM FOR PROTECTING AGAINST ROCKET-PROPELLED GRENADES
    Publication number: 20110232472
    Abstract: A bar armor system is provided for reducing damage caused by RPGs launched towards a vehicle. The bar armor system includes at least one bar array, comprised of lateral bars and vertical bars, wherein the lateral bars are set in predetermined positions so as to reduce the possibility of shaped charges being directed towards the target vehicle. Tubular shaft retainers are provided to be positioned in annular openings in the vertical bars. The lateral bars can be of a round or hexagonal cross-section, and when hexagonal lateral bars are employed, the flat surfaces of the cross-section are positioned horizontally by the tubular shaft retainers so as to minimize the area presented to an oncoming RPG, particularly when the RPG strikes at a non-normal incidence. Push washers can be employed at the outside surfaces of the vertical bars so as to hold them in position.

  • Hydrolysis system and process for devices containing energetic material
    Patent number: 7883676
    Abstract: A system for chemically disposing energetic material enclosed in assembled devices includes a porous basket. The porous basket forms an enclosed chamber for receiving the assembled devices. Further, the basket is supported by a rotatable basket arm that is, in turn, connected to a lifting arm. In addition to these structures, the system includes a tank that holds a hydrolysis solution. The tank is positioned to allow the lifting arm to submerge the basket into the solution. After submersion, the basket arm rotates the basket in the solution to flow the hydrolysis solution into contact with the assembled devices therein. As a result, the assembled devices react with the solution so that the solution penetrates the assembled devices, allowing the solution to contact and react with the energetic material to render the energetic material non-energetic.

  • Microwave-powered pellet accelerator
    Patent number: 7831008
    Abstract: A system for fueling a plasma includes a gyrotron for radiating microwave energy into a waveguide. Also included is a module having a deuterium-tritium (DT) fuel pellet, a diamond, quartz or sapphire window, and a pusher medium located between the pellet and window that is made of frozen deuterium (D2) and metallic particles. With the module in the waveguide, the gyrotron is activated. Radiation from the gyrotron is then directed into the waveguide and through the window to cause the inducement of current in the metal particles, causing the particles to become hot. The absorbed microwave energy is then transferred to the pusher medium by conduction resulting in a gaseous expansion of the pusher medium. This ejects the pellet from the waveguide and into the plasma.

  • Active armor system
    Patent number: 7819050
    Abstract: An improvement in an electric armor system designed to prevent, among other things, a rocket-propelled grenade (RPG) from penetrating the hull of a fighting vehicle. The system includes a self-clearing electrode that will make the system less vulnerable to non-plasma objects that might otherwise short out the active armor electrodes. It optionally further allows for the early initiation of current flow at the point of penetration making it even easier to defeat incoming threats by allowing more time to break-up an incoming plasma jet.

  • Material treatment systems for waste destruction, energy generation, or the production of useful chemicals
    Patent number: 7736471
    Abstract: A system for treating a feedstock for the purposes of waste destruction, energy generation, or the production of useful chemicals is disclosed and includes a reactor vessel. A heating lance is configured to outflow the products of a partial oxidation reaction into a reaction chamber in the vessel. The hot reaction products heat and pyrolyze the feedstock in the chamber generating a process effluent which typically includes gases (e.g. syn-gas) and carbon solids. Glasses and metals in the feedstock accumulate in the chamber in a molten state. The molten materials store thermal energy and provide thermal stability to the treatment system. A recycle loop uses carbon solids from the process effluent as an input to the lance for reaction with an oxidant therein.
