  • Method and system for remotely inspecting bridges and other structures
    Patent number: 9036861
    Abstract: Spatially Integrated Small-Format Aerial Photography (SFAP) is one aspect of the present invention. It is a low-cost solution for bridge surface imaging and is proposed as a remote bridge inspection technique to supplement current bridge visual inspection. Providing top-down views, the airplanes flying at about 1000 feet can allow visualization of sub-inch (large) cracks and joint openings on bridge decks or highway pavements. On board Global Positioning System (GPS) is used to help geo-reference images collected and facilitate damage detection. Image analysis is performed to identify structural defects such as cracking. A deck condition rating technique based on large crack detection is used to quantify the condition of the existing bridge decks.

  • COMPOSITE PLASMONIC NANOSTRUCTURE FOR ENHANCED EXTINCTION OF ELECTROMAGNETIC WAVES
    Publication number: 20150017433
    Abstract: The present disclosure explores and fabricates coupled plasmonic nanoparticles of gold (Au), silver (Ag), or aluminum (Al) onto nanorods or nanowires of zinc telluride (ZnTe), silicon (Si), germanium (Ge), or other semiconductor materials. Full-wave simulation is performed to obtain an optimum design for maximum light absorption. The nanorods, after being coated with a shell to form a p-n junction, or being imparted with a radial junction, are of interest for enhanced light harvesting in solar cells, for example. The fabrication method of such arrays is described. Modeling of the spectral properties using equivalent circuit theory is implemented to predict fabrication results and provide an intuitive approach regarding the design of these optical metamaterials with predetermined properties.

  • Passive vehicle suspension system providing optimal camber gain
    Patent number: 8882116
    Abstract: The present invention provides a passive vehicle suspension system providing optimal camber gain and avoiding the “bump camber” problem. This vehicle suspension system utilizes a conventional sway bar and a kinematic system to rotate the tire(s) of a vehicle in a direction opposite the roll of the vehicle during turning or cornering, for example. The kinematic design allows for adjustability and optimization, providing optimal camber gain. Although an automotive vehicle suspension system is illustrated and described, and, specifically, a racing or everyday automotive vehicle suspension system, the concepts of the present invention are capable of much broader applicability.

  • Composition and method for the restoration and preservation of transplant organs procured from DCD donors
    Patent number: 8802361
    Abstract: The present invention provides a perfusion solution comprising specific metabolic agents, antioxidant agents, and membrane stabilizer agents that can help improve preservation, organ viability, and in some cases recover organs that would otherwise being unusable for transplantation. In a further embodiment, the perfusion solution can be used in combination with hypothermic machine perfusion. It has been found that combination of the perfusion solution and hypothermic machine perfusion can help prevent or reduce further damage to the organ and restore the organ's anti-oxidant system, stabilize the cellular cytoskeleton and cellular membranes, inhibit arachidonic acid pathway, provide oncotic support, reduce interstitial edema formation, and help restore energy stores within the organ. As a result, the method can be used to improve the viability of otherwise marginal donor organs.
