  • Publication number: 20190372099
    Abstract: Provided is a method of producing a mass of graphene-embraced particulates, comprising (A) peeling off graphene sheets from graphite particles and directly or indirectly transferring these graphene sheets to encapsulate primary particles of an anode active material using an energy-impact device, wherein multiple graphene sheets are overlapped together to embrace or encapsulate a primary particle; and (B) combining the resulting graphene-encapsulated primary particles with additional graphene sheets, along with an optional conductive additive, to form graphene-embraced particulates. Also provided are an anode electrode comprising multiple graphene-embraced particulates and a battery comprising such an anode electrode.

  • Patent number: 10484463
    Abstract: The disclosure provides a load balancing system, a load balancing device and a topology management method. The topology management method includes configuring and maintaining a transmission progress value for each of edge servers; grouping the edge servers into server groups, wherein the edge servers of each of the server groups provide one of a plurality of video streams, and each of the edge servers is grouped into at least one server group among the server groups; selecting a first video stream from at least one video stream corresponding of a first edge server having bandwidth usage rate higher than a high load threshold; synchronizing video data of the first video stream to a second edge server; setting a transmission progress value of the second edge server as a transmission progress value of the first edge server; and adding the second edge server into the server group corresponding to the first video stream.

  • Patent number: 6437429
    Abstract: A semiconductor package is disclosed, such as QFN, SON. The semiconductor package includes a die, a package body for protection of a die, and a plurality of leads. A metal pad formed by some partial downside surface of each lead is located on a downside surface of the package body with coplanarity. Each lead has a cutting surface exposed on a corresponding lateral surface of the package body. The cutting surface has an interval with the plane of forming the metal pads by means of selectively self-etching the leads or stamping to bend the leads in order to avoid forming a cutting sharp edge in the brim of the metal pad after cutting.
