  • Patent number: 5621868
    Abstract: The precision of an initial image is reduced through image automatic processing in a manner simulating techniques used in the production of a custom art work. The resulting image, although generated without human intervention, has a pleasing, customized appearance which can be desirable to consumers seeking decorative art work. One way of reducing the precision of the initial image is modifying portions of the image to have more uniform luminance, color saturation, or color hue, producing a resulting image appearing to contain brush strokes. Alternatively, the precision of the initial image is reduced by locating contrast edges in the image, and modifying the luminance along these edges, producing a resulting image in which objects and features are outlined and have an enhanced definition from the background.

  • Patent number: 5613998
    Abstract: Tungsten carbide and/or tungsten can be recycled by oxidizing the tungsten composition at a temperature greater than 700.degree. C. to form a water insoluble tungsten trioxide. This is then reduced to form tungsten dioxide. The tungsten dioxide is subjected to a low temperature oxidation which forms monoclinic tungsten trioxide. The monoclinic tungsten trioxide is then dissolved in ammonia to form ammonium tungstate. If present, the binder metal such as cobalt is converted into the soluble ammine complex. This can be spray dried and carburized to form tungsten carbide. If the form composition includes cobalt or other binder metal, the ratio of cobalt to tungsten can be adjusted by adding cobalt salts or ammonium metatungstate to the aqueous solution prior to spray drying to form a precursor composition. This is uniquely suitable for forming a cobalt tungsten carbide composition.

  • Patent number: 5615227
    Abstract: A transmitter prepares digits for transmission, e.g. as spread spectrum data accompanying commercial radio, using code sequences having exactly zero cross-correlation. The code sequences include phased versions of the maximal length sequence, with an additional "0" bit appended to the end of each phased version. Information signals (which may be analog signals, or digital signals encoded as two or more analog levels) are transmitted by multiplying each information signal by one of the code sequences, and adding the resulting sequences together to form an output sequence for transmission. A receiver that recovers the information signals correlates the received sequence with each of the code sequences, producing results which are directly proportional to the information signals.
