  • Patent number: 5151945
    Abstract: A visual image comparison method is provided, including the steps of: obtaining a first digital representation of a first visual image, where the first digital representation comprises a first plurality of pixels, and each pixel has a gray scale indicative of light intensity; obtaining a second digital representation of a second visual image, where the second digital representation comprises a second plurality of pixels, and each pixel has a gray scale indicative of light intensity; and selectively making a first predetermined number of comparisons of corresponding pixels from the first and second digital representations to determine whether a difference in ambient light intensity exists between the first and second visual images, and, selectively making a second predetermined number of comparisons of corresponding pixels from the first and second digital representations if and only if no difference in ambient light intensity exists between the first and second visual images, and indicating an alarm condition

  • Patent number: 5091242
    Abstract: A composite article comprising a resin matrix containing both carbon fibers and a tin alloy. In the preferred embodiment, fiber containing layers within the matrix are separated by alloy containing layers within the matrix.The invention further includes the method of manufacturing the composite articles by impregnating layers of carbon fibers with a resin to form impregnated sheets, spreading alloy powder between the sheets and compression molding the resulting article at a sufficient temperature and pressure for a sufficient time to melt the alloy and cure the resin.
