  • Patent number: 10720993
    Abstract: A metasurface optical pulse shaper includes a metasurface with superpixels disposed on an entry side of the metasurface and a wire grid polarizer disposed on an exit surface of the metasurface for controlling a phase, amplitude, or polarization of an optical pulse, wherein the metasurface in combination with dispersers provide for optical shaping of the optical pulse. A process for optically changing a pulse shape includes dispersing a primary optical pulse; separating spatially, by frequency, primary frequency waves; changing, by superpixels, a relative phase of the primary frequency waves and producing phase waves that are separated spatially by frequency and phase; and producing a plurality of shaped frequency waves such that, from an individual phase wave, a shaped frequency wave is produced that separated spatially by frequency and phase, such that a superposition of shaped frequency waves produce a shaped optical pulse that has pulse shape that is different than the primary optical pulse.

  • Patent number: 10705930
    Abstract: The present disclosure describes example service takeover methods, storage devices, and service takeover apparatuses. In one example, when a communication fault occurs between two storage devices in a storage system, the two storage devices respectively obtain running statuses of the two storage devices. A running status can reflect current usage of one or more system resources of a particular storage device. Then, a delay duration is determined according to the running statuses, where the delay duration is a duration for which the storage device waits before sending an arbitration request to a quorum server. The two storage devices respectively send, after the delay duration, arbitration requests to the quorum server to request to take over a service. The quorum server then can select a storage device in a relatively better running status to take over a host service.

  • Publication number: 20200209277
    Abstract: Motion windows are generated from a query activity sequence. For each of the motion windows in the query activity sequence, a corresponding motion window in the reference activity sequence is found. One or more difference calculations are performed between the motion windows of the query activity sequence and the corresponding motion windows in the reference activity sequence based on at least one criterion associated with physical meaning. Abnormality of the motion windows is determined based on the one or more difference calculations. A standardized evaluation result of the query activity sequence is output based on the detected abnormal motion windows in the query activity sequence.

  • Publication number: 20200209276
    Abstract: Using a global optimization, a cycle within a frame buffer including frames corresponding to one or more cycles of query activity sequences is detected. The detection includes creating a plurality of cycle segmentations by recursively iterating through the frame buffer to identify candidate cycles corresponding to cycles of a reference activity sequence until the frame buffer lacks sufficient frames to create additional cycles, computing segmentation errors for each of the plurality of cycle segmentations, and identifying the detected cycle as the one of the plurality of cycle segmentations having a lowest segmentation error. Cycle duration data for the detected cycle is generated. Frames belonging to the detected cycle are removed from the frame buffer. The cycle duration data is output.
