A system for marking parts including an automated parts labeling software module for producing information labels for marking parts, a processor for executing the APL software module, and at least one of peripheral label device communicatively connected to the processor for receiving part identification information from the processor and marking said information labels. The reduction gear includes a shock absorbing member and restricting members. The resultant polymeric compositions are capable of forming complex optical interconnecting network structures. The second network node manages the assignment of the label resources available for a connection between the first network node and the second network node and preconfigured in the first network node. The first level grouping is assigned to a first scale level of a map.
