Abstract: Each data point within a two-dimensional code can be represented by a distribution of spots. Each spot can be made small enough to be invisible to the human eye so that the two-dimensional code can be invisible on or within transparent or nontransparent materials. The spots can be spaced at a large distance to increase the signal-to-noise ratio for an optical code reader. A code reader can be adapted to read the spots and determine the data points.

Abstract: A fluoroscopy C-arm drape clip for attaching a sterile drape to a C-arm of a fluoroscopy C-arm imaging unit and method of providing a sterile outer surface on a C-arm of a fluoroscopy C-arm imaging unit is provided. The drape clip includes a generally U-shaped band having a pair of legs and an arm. Each of the legs has a first end attached to the arm and a second end spaced from the arm. The legs extend away from the arm in non-parallel, laterally spaced relation with one another and have inner surfaces facing one another and an outer surfaces facing away from one another. Further, an elastic pad is attached to the inner surface of each of the legs adjacent the second ends.

Abstract: A method, system, and apparatus for intelligent application of a finishing process a surface of a housing is described. In one embodiment, at least a portion of the surface of the housing is imaged. In one embodiment, the image can be rendered using an optical imager such as a standard or high definition camera. In one embodiment, multiple cameras can be used to assist in defining location, size, and depth of surface defects. In one embodiment, an optical imaging device can be used to image surface defects under wet conditions where the surface of the housing is covered with a layer of slurry.
