  • Patent number: 6887714
    Abstract: A structure and method for chemical sensing utilizing microassays. Microcavities or micropores are combined with assay techniques to provide a very fast and very sensitive means of detecting chemical compounds. Assay techniques are modified to include a metal ion binding carrier species especially suitable for use in conjunction with the electrochemical detection. This allows assays to be combined with electrochemical analysis, thus allowing the high speed ease and hypersensitivity available in the invention disclosed herein.

  • Patent number: 6872562
    Abstract: The present invention is directed to herbicide resistant N2 fixing bacteria. The bacteria are useful for effecting N2 fixation, nodulation, growth and yield of herbicide resistant or tolerant leguminous plants treated with herbicide. The bacteria are particularly useful for providing competitive advantage to superior N2 fixing rhizobial strains over non-resistant indigenous rhizobia for nodulation of herbicide resistant or tolerant leguminous plants.

  • Patent number: 5933276
    Abstract: There is disclosed a partially transparent, directional viewing sheet formed of plastic material with convex and concave lenses of elliptical cross-section, preferably lenticular lenses, formed respectively on the front and back surfaces of the sheet, there being intervening spaces with convex surfaces between the concave lenses which spaces are not transparent to images and may be imprinted with an image that is viewable through the sheet from some directions. Preferably the concave lens focal length is typically about one-half of the focal length of the convex lens. Elliptical cross-section of the lenses minimizes spherical aberration and sharpens the focus. The thickness of the sheet causes focal points of the lenses to substantially coincide producing the effect of a tiny Galilean telescope.
