Abstract: In one embodiment of the invention, an object oriented autorouter is disclosed for routing nets in a circuit. The object oriented autorouter includes a routing data model (RDM); at least one routing engine, such as a single connection router (SCR), a topographical (TOPO) transformation engine, and a detail geometric (DETAIL) engine, and a command and control module (CCM) coupled together. The RDM reads and write data with a design database as well as reading one or more object oriented design constraints. Each of the routing engines have at least one action to operate on the design database to improve compliance of the circuit to a constraint. The CCM controls the overall routing process of the nets in the circuit and includes at least one director to invoke at least one of the routing engines to achieve compliance with one or more constraints.

Abstract: A method and system for auto-routing wiring within a PCB. In some embodiment, a first broad region within a first layer and a counterpart first broad region within a second layer are defined. The counterpart regions define a first broad via location. In some embodiments, the first and second broad via locations of the first and second layers can then be subdivided into a plurality of triangular regions. The triangular regions on the first and second layers can then be compared to more accurately locate an appropriate via location.

Abstract: A bag carrying system having a removable handle and wheel assembly is provided. The system includes a bag having a back portion with a panel overlying the back portion and a handle and wheel assembly comprising a handle portion, a wheel portion and a longitudinally extending supporting element connected therebetween. Significantly, the longitudinally extending supporting unit of the handle and wheel assembly is designed to be placed between the panel and back portion of the bag for releasably attaching the assembly thereto.

Abstract: The present invention provides an incentive for buying a ring binder or a spiral notebook. The incentive is provided by having the binder or notebook include one or more internal folded sheets, preferably in the form of poster panels, which may be disposed within the binder or notebook and thereafter removed and, in the case of multiple sheets, unfolded for display separate from the binder or notebook. The poster panel or panels may coordinate with artwork on the cover of the binder or notebook.

Abstract: The present invention provides a folder into which an appendage is created on the interior surface of the folder's pocket. The appendage is tab-like and may be removed from the inside pocket. The appendage is formed so that after it is removed, it may be used as a separate bookmark, picture or note sheet. Preferably graphics are provided on the appendage which may complement or coordinate with graphics elsewhere on the folder. The folder may have one or more appendages. Perforations are provided to enable the appendage to be removed by tearing off the appendage from the surface of the pocket.
