  • Patent number: 11841355
    Abstract: The invention provides an intelligent quantitative microscopic identification system for whole rock polished sections, which can greatly improve the collection efficiency of whole rock polished sections by adopting a microscopic collecting apparatus. In a preferable technical solution, the microscopic collecting apparatus is combined with the production line for the automatic preparation of whole rock polished sections to form an integrated system, which realizes an automatic solution from preparation to collection, therefore further improves the production and collection efficiency of whole rock polished sections, and which can cope with production, image collection and automatic scanning and splicing of mass whole rock polished sections, so it greatly improves the collection efficiency of the microscopic images of organic components for whole rock polished sections. People can collect 500 to 1000 sample pieces of whole rock polished sections in 12 hours by adopting the solution of the invention.

  • Patent number: 10020907
    Abstract: A method for virtualizing an optical network, comprising: abstracting optical resource information corresponding to resources within the optical network, constructing a plurality of candidate paths for one or more optical reachability graph (ORG) node pairs, determining whether the candidate paths are optical reachable paths, and creating an ORG link between each ORG node pair when at least one optical reachable path exists for the ORG node pair, wherein linking the ORG node pairs creates an ORG. In another embodiment, a computer program product comprising executable instructions when executed by a processor causes a node to perform the following: determine an optical network's optical-electrical-optical (OEO) conversion capability, partition a plurality of service sites into one or more electrical reachability graph (ERG) nodes, determine a grooming capability for each ERG node, and construct a plurality of electrical-layer reach paths between the ERG nodes to form an ERG.
