  • Transport system incorporating linear motor charged electric vehicle
    Patent number: 8109353
    Abstract: A system and method are provided for moving a vehicle along a roadway. The system includes at least one power segment that incorporates a multiple-phase winding. Structurally, the winding is embedded into the roadway for interaction with a magnet system mounted on the vehicle. With this interaction, a Linear Synchronous Motor (LSM) is established between the roadway and the vehicle to drive movement of the vehicle along the roadway. Also, the vehicle includes a mechanism for initially synchronizing a waveform speed of the multiple-phase winding with the speed of the vehicle. Further, the vehicle is able to selectively establish the LSM for use when desired.

  • Active armor systems
    Patent number: 8074554
    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.

    Abstract: A reflective coating is disclosed that has a base layer provided with a reflective surface for reflecting electromagnetic radiation, such as visible and solar near-infrared light. The reflective coating also has a dielectric layer formed on the reflective surface, and an absorber layer. The absorber layer is formed on the dielectric layer that is formed on the base layer. The reflective coating has an average reflectance greater than about 60% for wavelengths of electromagnetic radiation in the range of 800 to 2500 nm that is irradiated upon the reflective coating. Additionally, the reflective coating has an average reflectance for wavelengths of electromagnetic radiation in the range of 400 to 700 nm irradiated upon the reflecting coating that is less than the average reflectance of the reflective coating from 800 to 2500 nm.

  • METHODS AND COMPOSITIONS FOR ASSAYING ENZYMATIC ACTIVITY OF MYELOPEROXIDASE IN BLOOD SAMPLES
    Publication number: 20110287468
    Abstract: The present invention provides a two-step assay for measuring myeloperoxidase (MPO) activity in a blood sample. The first step utilizes a chromogenic substrate to measure first peroxidase activity including MPO activity in the sample, whereas the second step measures non-MPO peroxidase activity in the presence of the same chromogenic substrate and a specific MPO inhibitor. Specific MPO peroxidase activity is then determined by comparing the non-MPO peroxidase activity and the total peroxidase activity. The MPO peroxidase activity obtained in this fashion may be proportional, and preferably directly proportional, to the mass of MPO in the sample. Kits for assaying MPO peroxidase activity based on the same principle are also provided.

  • 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.
