  • Patent number: 7773797
    Abstract: The present invention relates to a high-performance computer vision system and method for measuring the wings deformation of insects with high flapping-frequency, large stroke-amplitude and excellent mobility during free-flight. A geometrical optic unit composed of a polyhedral reflector with four reflection-planes and four planar reflectors is used to image one high-speed CMOS camera to four virtual cameras, combined with double laser-sheet sources, multiple virtual stereo and structured-light sensors are available to observe the free-flight of insect at different viewpoints simultaneously. In addition, an optoelectronic guiding equipment is included to lead the free-flight of insect and trigger the camera to capture the image sequences of insect-flight automatically. The deformation of insect-wings can be reconstructed by the spatial coordinates of wing-edges and the distorted light-lines projected on the surface of wings.

  • Publication number: 20090221542
    Abstract: Provided are methods of attenuating release of a proinflammatory cytokine from a mammalian cell. Also provided are methods of inhibiting or treating an inflammatory cytokine cascade in a mammal. Further provided are methods of treating a mammal at risk for or undergoing sepsis, septicemia, and/or endotoxic shock. Additionally provided are methods of attenuating NO release from a mammalian cell. Also provided are methods of attenuating NO production in a mammal at risk for, or having, a disorder mediated by excessive NO production.
