Filed: 1997-06-05
Abstract: A self-propelled model vehicle adapted for use on a closed loop raceway having a guide slot coextensive, therewith is provided with a guide arm including a downwardly depending  guide pin that engages with the guide slot of the raceway. The guide slot defines the boundary between two adjacent lanes of the raceway. The guide arm is controlled by a motor for lateral movement The lateral movement of the guide arm forces the guide pin against a side of the guide slot to effect the lateral displacement of the model vehicle into the adjacent lane of the raceway. Also provided is a raceway layout comprising a plurality of modular sections each section having an integral guide slot therein. In the assembled mode the guide slot defines a closed loop guide way for engaging a slot car.

IPC: H04B10/27
Filed: 1999-05-04
Abstract: Methods for provisioning optical communications networks employing wavelength division multiplexing (WDM) technology provide for routing and wavelength assignment of a set of connection requests. Avoiding many of the pitfalls of exactly optimum solutions, the present heuristic methods provide much shorter execution times while providing near-optimum performance. Adaptations of the basic solutions provide design of restorable networks capable of handling a specified set of failures. This approach advantageously is based on considering all failures simultaneously, and performs better than solutions in which independent designs are developed for each failure. Networks designed using these methods store configuration information for primary network configurations and for one or more restoration networks. Upon startup or upon network failures, predetermined configuration directions are applied to wavelength selective cross-connects (WSXC) at each network node to establish (or reestablish) desired network node interconnections.
