  • Pattern inversion for improved resolution in 3D imaging
    Publication number: 20100007660
    Abstract: A system and method for improving resolution of a 3-D image by pattern inversion is disclosed. An image of a marker pattern transmitted from the surface of a 3-D object is captured with a sensor and analyzed using a 3-D image analysis method. The respective light and dark areas in the image are then inverted. The inverted image is then analyzed using a 3-D image analysis method, whereby the inversion allows for analysis of a greater portion of the image, resulting in a higher resolution 3-D image than without inversion.

  • Single-lens aperture-coded camera for three dimensional imaging in small volumes
    Patent number: 7612870
    Abstract: Determining instantaneously three-dimensional coordinates of large sets of points in space using apertures associated with cameras or camera parts. An embodiment associates information from the apertures with different portions of the imager, so that portions on the imager do not overlap.

  • Centrifuge and cascade for the separation of gases
    Patent number: 6716269
    Abstract: A gas centrifuge operating to separate gases of differing chemical composition and molecular weight by a centrifugal force field. Such a centrifuge is operable to separate methane and carbon dioxide, and to produce torque, and a cascade of such centrifuges is operable to concentrate produced streams of carbon dioxide and methane, and to produce torque. A compact centrifugal gas processing system incorporating the gas centrifuge with other centrifugal components, is also provided.
