Abstract: The present invention provides calixpyrrole, calixpyridinopyrrole, and calixpyridine macrocycles, having 4, 5, 6, 7, or 8 heterocyclic rings, as well as syntheses, derivatives, conjugates, multimers, and solid supports thereof. Such macrocycles have proved to be effective and selective ion- and neutral molecule-binding agents forming supramolecular ensembles, and ion- and neutral molecule-separation agents. The macrocycles are fully meso-non-hydrogen-substituted porphyrinogens, a few molecules of which were previously known but not recognized as possessing anion- or molecule-binding properties. The binding mode is noncovalent, primarily that of hydrogen-bonding, thereby providing a new mode for liquid chromatography, that of Hydrogen Bonding Liquid Chromatography. Further useful applications of the macrocycles provided herein include environmental remediation by removal of undesired ions or neutral molecules, and removal of phosphate for kidney dialysis.

Abstract: The present invention provides for the safe and effective installation of staples. The device has a hollow body at its upper end, a cap plate with an opening attached to the upper end of the body, and a driver shaft mounted to slide within the cap plate. A block is secured within the body at the lower end of the body remote from the cap plate. The block has two channels and a striker slides through the channels. An indentation is located in the lower end of the block to hold the arch of a staple. A driver plate slides within the body and is secured to the driver shaft on one side and to both strikers on the opposite side. A driver spring and a pair of striker springs surround the driver shaft and strikers, respectively. The channels guide the strikers while the indentation positions the staple. This causes the strikers to strike the brads of the staple simultaneously, without damaging either the staple or the brads and, most importantly, the wiring or cabling the staple secures.

Abstract: Method and system for optimally estimating the location of each of a sequence of two or more synchronization patterns in a digital signal bit stream. A first reference location for a sync pattern is determined. A Boolean product or other product of the sync pattern (of length S) with S consecutive bit values of the digital stream is formed, for each of a selected consecutive sequence of candidates for a second reference location of the sync pattern within a window of selected length. A candidate reference location that yields the largest (or smallest) product value within the window is estimated to be a second or “next” reference location of the sync pattern, if the product value is at least equal to (or, alternatively, is no greater than) a selected threshold value. The sync pattern used for testing the digital stream can be varied from one location to another. The number of bit matches or the number of bit non-matches can be used to determine an optimal reference location for the sync pattern.

Abstract: A timing circuit used in reading disc media or other dada includes multiple sync detection circuits.

Uniquely definable sequences of sync patterns are used to determine a position of sync patterns within a sector of data.
