Abstract: An assembly for clamping flanged tubular components, the assembly including a segmented clamp having a recess configured to accept the flanges of the tubular components, and a hole oriented substantially perpendicular to the longitudinal axes of the tubular components. The assembly also includes a housing surrounding an outer portion of the segmented clamp and configured for attachment to at least one of the tubular components, and a drive screw that passes through the housing and is threadedly engaged with the hole of the segmented clamp. As the drive screw rotates, it drives the segmented clamp perpendicularly relative to the tubular components between a locked position, in which the circumferential recess engages the flanges of the tubular components, and an unlocked position, in which the circumferential recess is positioned laterally out of engagement with the flanges of the tubular components.

Abstract: A method for smoothing artificial discontinuities between image blocks associated with digital data comprises reconstructing a block-based pixel representation of image blocks associated with digital data. If the difference between adjacent image blocks of the block-based pixel representation is less than or equal to a quantization parameter, then the method includes modifying boundary pixel values to define at least one additional frame, and displaying the at least one additional frame and an original frame in an alternating fashion so as to visually achieve smooth block boundaries between the adjacent image blocks. The method may be performed by a suitable device and/or may be embodied in an instruction set executable by such device.

Abstract: A 3-D dot code is embedded in a printed medium using an embedder that embeds data directly into the halftone dots of a selected file that is ready for printing. An extractor extracts the embedded bits by scanning the printed medium and then interprets the embedded data. A bleed-through elimination module in the extractor is able to eliminate adverse affects on the scanned input of the embedded data caused by bleed-through from the print on the opposite side of the page. The extractor may also include a module that compensates for a misaligned scanned input by automatically detecting the rotation and translation, and then registering the image so that the upper-left corner is located in a certain position. This operation expedites subsequent data retrieval, in which data is read by block matching.

Abstract: The appearance of edges in an image is improved through precise placement of subpixels within pixel cells that are located on or near edges in an image. Image data is examined to identify a “target pixel” near the edge of an object that represents the object and is adjacent to a “background pixel” that represents only background. The target pixel may represent both the object and its background or it may represent the object only. A “second pixel”, adjacent to the target pixel and representing the object, is also identified. The second pixel may represent both the object and its background or it may represent the object only. The target pixel's location with respect to the second pixel is analyzed to determine the placement of a subpixel within the target pixel cell and the placement of a subpixel within the second pixel cell, such that the edge of the object is well-defined and the density of the object is preserved.

Abstract: A superpattern generator uses a first halftone pattern representing a first gray level and a second halftone pattern representing a second gray level to generate a larger pattern or “superpattern”. In a preferred implementation, the superpattern generator generates a grid of elements to be used as a template for the superpattern, calculates a distance value representing the “distance” from the first gray level to a desired gray level TX, determines how many elements of the grid represent the first halftone pattern and how many represent the second halftone pattern based on the distance value, superimposes a dither matrix on the grid and assigns values representing the first halftone pattern or the second halftone pattern to pixels within the elements of the grid by examining threshold values in the dither matrix. This process is repeated for various values of TX to generate a set of superpatterns representing a set of gray levels intermediate to the first gray level and the second gray level.
