  • Publication number: 20200041910
    Abstract: A shutter blade assembly for a photolithography machine, a large-field of view (FoV) photolithography machine and an exposure method are disclosed. A scan-ning-directional shutter blade subassembly is moved once during each illuminance test and then moved above alignment marks after the test. During exposure, the scanning-directional shutter blade subassembly moves with a mask stage in the same direction and at the same speed so that it stays stationary relative to the alignment marks on a photomask (4). In case of full-FoV exposure, it is not necessary for a non-scanning-directional shutter blade subassembly to be moved, while in case of partial-FoV exposure, it is moved into the partial exposure FoV and defines there a window for obtaining a light spot with a desired shape by modulating illumination light.

  • Patent number: 10476928
    Abstract: A network video playback method and an apparatus, where location information of an independently decoded frame in a media segment and location information of a non-independently decoded frame that is in the media segment and that references the independently decoded frame are added to a segment index in order to determine a video frame closest to an access time point from the independently decoded frame and the non-independently decoded frame. The independently decoded frame that is referenced by the video frame closest to the access time point is acquired when the video frame closest to the access time point is the non-independently decoded frame, and decoding starts from the video frame closest to the access time point according to the referenced independently decoded frame, and video playback is performed. Hence, access accuracy of network video playback can be improved.

  • Publication number: 20180302299
    Abstract: A service level agreement (SLA) system is provided for multi-tenant cloud computing to enable provisioning of computing instances for tenants with a networking SLA. A networking SLA may specify a bandwidth requirement, for example, between instances to be scheduled for a tenant in a datacenter. The SLA system evaluates nodes in the datacenter based on a remaining capacity of links associated with nodes implementing the networking SLA. A modular system is provided to enable integration of the SLA system into existing cloud computing infrastructures. The cloud management system may query the SLA system to determine nodes in the datacenter capable of meeting a networking SLA. The list may be ordered to indicate nodes having better capacity to fulfill the networking SLA. The cloud management system can utilize the ordered list of nodes in scheduling instance deployments for tenant requests.

  • Publication number: 20180212889
    Abstract: An apparatus, such as a network element, comprises a receiver to receive a plurality of packets. A memory stores instructions and forms a first and second set of virtual queues to store the plurality of packets. A processor having one or more cores with one or more packet classifiers provides a classification of a packet in the plurality of packets. The processor in communication with the memory executes instructions to transfer the packet from the receiver to a virtual queue in the first set of virtual queues based on the classification. The processor also transfers the packet from the virtual queue to a transmitter based on a demand rate value and supply rate value associated with the virtual queue.
