Abstract: The present embodiments are directed generally to techniques for providing an interactive environment that gives visual feedback and indicators to identify and/or encourage effective sharing of partially used drill sites, all inside a typical etch-edit environment. Such an interactive environment allows designers to effectively leverage and exploit new PCB manufacturing techniques that allow for multi-net use of a single drill hole.

Abstract: A method of manufacturing a premeasured compressed charge in which the compressed charge has a leading end portion with a smaller dimension than both a trailing end portion and a desired caliber of the intended firearm and the trailing end portion has a larger diagonal dimension than the desired caliber of the firearm. The method comprises the steps of providing a mold with cavities, filling the mold cavities with gunpowder, pressing gunpowder to form a compressed charge so that one of a density and a compaction of the gunpowder, adjacent the leading end portion of the compressed charge, is about 0% to about 5% less than the density or the compaction of the gunpowder adjacent the trailing end portion to facilitate a more complete combustion of the compressed charge upon discharge of the firearm, and removing the compressed charge from the cavities.

Abstract: A clean burning premeasured compressed charge for use in black powder firearms as well as cartridges. The premeasured compressed charge is manufactured to have a substantially desired shape which facilitates improved flame propagation by the leading end wall and along the exposed sidewall surfaces of the compressed charge to result in a more complete and rapid burning of the compressed charge both from the leading end wall toward the trailing end wall and also radially inwardly from each one of the four sidewalls toward a center of the premeasured compressed charge. The premeasured compressed charge has a leading end portion and a trailing end portion and the leading end portion is either the same size or a smaller dimension than the trailing end portion.

Abstract: A method and apparatus to adaptively validate a physical net routing topology of a substrate design to a target topology of the substrate design. A tree data structure is generated by mapping physical net routing topology objects to tree data structure objects the tree data structure representing the substrate design. The tree data structure is then compressed to form a compressed tree data structure. The compressed tree data structure is validated by comparing the target topology with the compressed tree data structure to determine if the target topology is electrically equivalent to the compressed tree data structure. One or more branches of the validated tree data structure is named, and the validated tree data structure is partitioned and saved.

Abstract: A system to evaluate a distance between polyline segments includes identification of a first polyline and a second polyline associated with a differential signal, determination of whether a distance between a segment of the first polyline and a segment of the second polyline is within a first tolerance, and, if the distance is not within the first tolerance, determining whether the distance is within a second tolerance. If the distance is not within the first tolerance and is within the second tolerance, it is determined whether the length of the segment of the first polyline is less than a first threshold. If the distance is not within the first tolerance and is within the second tolerance, and if the length of the segment of the first polyline is less than the first threshold, it is indicated that the first polyline and the second polyline are sufficiently spaced.

Abstract: A transport container with a removable cover which is repeatedly removable and refastenable to the transport container. The transport container is sized to accommodate a plurality of individual premeasured charges of gunpowder. Each of the plurality of individual premeasured charges of gunpowder comprises a tube which is open at least one end thereof and the at least one open end of the tube is sealed with a removable cap once a suitable quantity of the loose granular charge of gunpowder is loaded therein. Each individual premeasured charge of gunpowder is loaded with gunpowder which has a relatively low moisture content to facilitate reliable and substantially complete ignition of all of the gunpowder ignition, upon detonation of a firearm.
