  • Publication number: 20150375192
    Abstract: The present system provides a reactor vessel for reducing a mixture of carbon dioxide and a reactant to a product by exposure to gamma radiation from spent fuel rods. The reactor vessel is constructed of a material that permits a substantial portion of the incident gamma radiation to pass through the wall, such as carbon fiber, silicon, or other low-Z material. An inlet tube introduces a mixture of carbon dioxide and a reactant into the interior of the vessel, where the mixture flows through the vessel to expose the mixture to gamma radiation to reduce the mixture to at least one product. In this way, spent radioactive fuel rods can be utilized for carbon dioxide reduction and for the production of useful chemicals.

  • Patent number: 8254017
    Abstract: A method is provided for forming an optical fiber amplifier. The method comprises providing a composite preform having a gain material core that includes one or more acoustic velocity varying dopants to provide a longitudinally varying acoustic velocity profile along the gain material core to suppress Stimulated Brillouin Scattering (SBS) effects by raising the SBS threshold and drawing the composite preform to form the optical fiber amplifier.

  • Publication number: 20070114359
    Abstract: Apparatus, and a related method, for eliminating the effect of speckle images caused by surface imperfections in a primary mirror of a stellar coronagraph. Depending on their size, mirror imperfections can result in speckles in a field of view that also includes an image of a distant target planet. By generating a traveling surface wave in the mirror surface, and then tuning the spatial wavelength of the surface wave to approximately match that of a surface imperfection, the speckle image corresponding to that surface imperfection is made to twinkle in irradiance. Tuning the traveling surface wave though a wide range of spatial wavelengths causes each speckle image in turn to be identified by twinkling, while the target planetary image remains unvarying. Accordingly, multiple speckles corresponding to different mirror imperfections may be conveniently eliminated by image processing.

  • Patent number: 6244758
    Abstract: A system for locating and monitoring electronic devices utilizing a security system that is secretly and transparently embedded within the software, firmware, or hardware of a computer. This security system initiates the client computer to periodically and conditionally call a host system to provide unique identifying indicia and location information. In one embodiment, the security system calls the host through a public switched telephone network (PSTN) and transmits the indicia in encoded form. In an alternative embodiment, which may be incorporated concurrently with the PSTN application, the security system calls the host system through the Internet and provides the host with indicia encoded within the DNS query sent. The host system is able to identify the calling computer from the indicia and is able to physically locate the computer through either caller identification or by referencing the Internet links which were used to connect the calling computer with the host system.
