Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 356: Optics: Measuring And Testing

Methods and apparatus (1) for analyzing light to measure or test its characteristics, such as intensity, color and polarization; (2) for determining the optical or nonoptical properties of materials or articles by noting, as by inspection, measurement, or test the effect produced by the materials or articles on light associated therewith; and (3) for measuring the dimensions of structures or the spatial relationships such as distances or angle bearings of spaced points by comparison of the respective properties (usually direction or spatial position) of the light from these points or by comparison of the properties of these lights with some scale or standard. The light analyzing includes or is for spectroscopy, interference, polarization, beam direction or pattern, focal position of a light source, shade or color, and photometers. The material or article properties determined are or involve crystal or gem examination, material strain analysis, blood analysis, optical pyrometers, egg candling, cutting blade sharpness, oil testing, document verification, flatness, lens or reflector testing, refraction testing, monitoring moving webs or fabrics, light transmission or absorption, light reflection, inspection for flaws or imperfections in materials, and thread counting. The dimensioning and spatial relationship determination includes triangulation by a light beam, contour plotting, range or height finders, motion stopping, velocity or velocity/height measuring, sighting where the optical element or reticle moves with the sighted object, particle size determination, particle light scattering, electrophoresis, angle measuring or axial alignment, mensuration or configuration comparison, alignment in a lateral direction, and fiducial instruments.

Class 358: Facsimile And Static Presentation Processing

Communication or reproduction of a static image or sequence of static images in which the local light, or density variations composing the image do not vary with time by a method or apparatus involving at least one of the following steps: (1) scanning a static image to capture an image-containing area by resolving it into an area; (2) communication of an image-representative signal or image-representative data over any supporting communication network; or (3) reproduction of an image-containing area in response to an image-representative signal or image-representative image data by reproducing a corresponding image area which at least one of the two dimensions is elemental, simultaneously or in a sequence. In this class, a facsimile system or method is a system or method for the communication or reproduction of an arbitrarily composed image in which the local light, or density variations composing the image do not vary with time, such as documents maps, charts, photographs, etc., but not motion picture film or video.
