  • Patent number: 8495214
    Abstract: The present invention discloses a system and method for CSCF entity disaster tolerance and load balancing the system comprises P-CSCF entities, I-CSCF entities and S-CSCF entities, and further comprises a DNS Server. The present invention uses a DNS UPDATE message to report the load equivalent weight of the CSCF entity at regular time, so that the DNS Server can use the load equivalent weight when executing the load balancing strategy. It makes the disaster tolerance and load balancing in the IMS network be much easier to use and extend, thus reducing the load of the IMS network.

  • Patent number: 8458631
    Abstract: The present disclosure provides for methods of reducing cycle time in data preparation. In one embodiment, a method includes receiving an initial integrated circuit (IC) design layout and an optical proximity correction (OPC)-processed initial IC design layout, and receiving a revised IC design layout. The method further includes comparing the revised IC design layout to the initial IC design layout to identify a difference region of the revised IC design layout from the initial IC design layout, performing an OPC on the difference region of the revised IC design layout, and merging the OPC-processed difference region of the revised IC design layout with the OPC-processed initial IC design layout.

  • Patent number: 8237174
    Abstract: The present invention discloses an LED structure, wherein an N-type current spreading layer is interposed between N-type semiconductor layers to uniformly distribute current flowing through the N-type semiconductor layer. The N-type current spreading layer includes at least three sub-layers stacked in a sequence of from a lower band gap to a higher band gap, wherein the sub-layer having the lower band gap is near the substrate, and the sub-layer having the higher band gap is near the light emitting layer. Each sub-layer of the N-type current spreading layer is expressed by a general formula InxAlyGa(1-x-y)N, wherein 0?x?1, 0?y?1, and 0?x+y?1.

  • Publication number: 20110271239
    Abstract: The present disclosure provides for many different embodiments. A mask fabrication method and system is provided. The method and system identify critical areas of an integrated circuit (IC) design layout that has undergone optical proximity correction. The critical areas are areas of the OPCed IC design layout that are at risk for hot spots. A lithography process check is then performed on the critical areas of the OPCed IC design layout.
