Abstract: In general, the invention relates to a method for performing polygon dissections in a geographic information system. The method includes receiving a notification of a spatial update for a number of polygons, where each of the number of polygons overlaps at least one of a number of previously dissected polygons, determining that a dissection is required based on the spatial update, and obtaining an updated polygon, associated with the spatial update, and related polygons of the number of polygons, where each of the related polygons overlaps the updated polygon. The method further includes dissecting the updated polygon and the related polygons to obtain a number of dissected polygons and replacing at least one of the number of previously dissected polygons with the number of dissected polygons, where the at least one of the number of previously dissected polygons is invalid based on the spatial update.

Abstract: A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.

Abstract: An airbag assembly is disclosed for use in automotive protective systems. In one embodiment, the airbag assembly includes a cover with one or more ribs. A tray defines a cavity for housing an airbag and includes one or more channels that each receive a corresponding rib. An end of the cover is secured to an end of the tray. Upon deployment of an airbag, the cover pulls from the tray and dislodges the ribs from the channels.

Abstract: A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.

Abstract: A fluid contactor is taught for mixing and reacting of fluids. Mixing is enhanced by providing a suitable residence time and suitable surface area contact by forming eddy flow within the fluid and thereby the formation of vortexes. Such a contactor does not require the use of mechanical mixers. The contact chamber of the present invention can enhance chemical modification by use of chemical modifiers such as ultraviolet lamps, by allowing the positioning of such modifiers adjacent the vortexes.

Abstract: The present invention relates to a binder composition comprising a polycarbonate polymer; an ethylenebisamide wax; a guanidine wetting agent, and an additive which accelerates or delays completion of debinding of the binder composition. The present invention further relates to a method for forming a sintered part by powder injection molding, including the steps of forming a green composition comprising a binder and an inorganic powder, wherein binder is a composition comprising a polycarbonate polymer, an ethylenebisamide wax, a guanidine wetting agent and an additive which accelerates or delays completion of debinding of the binder; melting the composition; injecting the composition into a mold for a part; heating the part to a temperature at which the binder decomposes; heating the part to a temperature at which the inorganic powder is sintered. The binder composition of the present invention is useful for press and sinter applications as well as for powder injection molding applications.

Abstract: An apparatus for inserting a venturi tube having an inlet, an aspirator inlet and an outlet directly within a fluid flow stream, with the aspirator inlet not in contact with the fluid flow stream is disclosed. A plate having a first aperture leading to the venturi inlet, and a series of second apertures both supports the venturi within a conduit and divides the fluid flow stream into a first stream which flows through the venturi tube and a second stream which flows around the venturi tube. A variety of adjusting mechanisms are disclosed for varying the cross sectional area of the second apertures relative to the cross sectional area of the venturi tube. The apparatus is adapted to allow the back pressure within the venturi tube (which increases as the fluid flow rate increases) to force an increasing proportion of the flow stream to flow around the venturi tube in order to maintain a relatively constant aspiration rate within the venturi tube.
