The present invention relates to a system for facilitating design and production engineering processes in a multi-disciplinary computer aided design environment. The system includes first enterprise including a workstation running a CAD application relating to a first engineering discipline; a second workstation running a CAD application relating to a second engineering discipline; a first storage device coupled to the first workstation; a second storage device coupled to the second workstation; a server executing a multi-discipline universal CAD library application; and a network connection for allowing the workstations and the server to communicate. The system also comprises a communications link to a second enterprise for allowing the second enterprise to communicate with the first enterprise. The system also comprises a commercial database accessible to both enterprises via the communications link. The multi-discipline universal CAD library tool utilizes standard component parts definitions to allow the enterprises to share information relating to CAD processes and data over the web.

Disclosed is a method of reworking a circuit panel, and a reworked circuit panel structure. The method includes providing a conformal, polymeric, dielectric coating or coatings on the surface of the panel, providing conductive circuitization atop the conformal, polymeric, dielectric coating or coatings on the surface of the panel, and providing a top conformal, polymeric, dielectric coating atop the conductive circuitization layer. Also disclosed is a rerouted circuit panel having at least two surface features that are connected by a rerouted current lead. The current lead is formed of a dielectric encapsulated conductor electrically joining the two surface features. The dielectric encapsulated conductor structure includes a conformal, polymeric dielectric bottom layer adherent to a surface of the circuit board, with a provided conductor on the conformal, polymeric dielectric layer, and a conformal, polymeric dielectric layer provided atop the provided conductor. The polymeric dielectric bottom layer may include one or more layers atop one another.

An apparatus for eliminating sidestream smoke from a cigarette or other smoking article includes a smoke collecting chamber adapted to collect sidestream smoke from the lit end of the smoking article along with air for combustion of the sidestream smoke and to direct the mixture of sidestream smoke and air to a combustion area associated with the smoke collecting chamber. An ignition device is included in the apparatus for igniting at least a portion of the sidestream smoke received in the combustion area by heating the smoke in the combustion area to an ignition temperature. The preferred ignition device includes a heat source for constantly producing a flame in the combustion area. The apparatus may also include a smoke particle capturing arrangement in a capture chamber connected to the smoke collecting chamber. The smoke particle capturing arrangement is adapted to remove smoke particles from the sidestream smoke or to capture smoke particles in the combustion area on a suitable ignition surface so that the igniting device may ignite the captured smoke particles.
