    • A portable fluid blower with a housing having a central axis and defining a fluid flow path extending axially between an upstream inlet and a downstream outlet. A fan assembly has a rotary component that is operable to draw fluid into a first stage of the flow path and accelerate fluid incoming at the inlet radially outwardly to against a first housing surface portion that diverts the fluid to a second stage of the flow path. The second flow path stage is defined by facing second and third housing surface portions that cause the fluid to flow substantially fully axially in an annular space extending around the central axis between the first stage and a third stage. The fluid flows from the third stage to and through the downstream outlet.
    • 一种便携式流体鼓风机,其具有具有中心轴线并且限定在上游入口和下游出口之间轴向延伸的流体流动路径的壳体。 风扇组件具有旋转部件,该旋转部件可操作以将流体引入流动路径的第一阶段并且加速流体在入口处径向向外进入,以抵靠将流体转移到流动路径的第二阶段的第一壳体表面部分。 第二流路台阶由面对第二和第三壳体表面部分限定,使得流体在围绕第一阶段和第三阶段之间的中心轴线延伸的环形空间中基本上完全轴向流动。 流体从第三级流到下游出口并通过下游出口。

    • A virtual storage migration method is provided, including: starting a data migration process, and copying, from a source storage device to a destination storage device, a data block in a virtual disk to be migrated; when a VM front-end I/O read request is received, directly reading, corresponding data from the source storage device; when a VM front-end I/O write request is received, determining whether a migration data block that corresponds to the write request is being migrated, if yes, executing a write operation that corresponds to the write request after the migration of the migration data block is completed, if no, executing a write operation that corresponds to the write request; and after all the data blocks in the virtual disk to be migrated are copied to the destination storage device, stopping the data migration, and switching the virtual disk from the source storage device to the destination storage device.
    • 提供了一种虚拟存储迁移方法,包括:启动数据迁移过程,以及从源存储设备向目标存储设备复制要迁移的虚拟磁盘中的数据块; 当接收到VM前端I / O读取请求时,直接从源存储设备读取相应的数据; 当接收到VM前端I / O写请求时,确定是否正在迁移与写请求相对应的迁移数据块,如果是,则迁移迁移数据之后执行与写请求对应的写操作 块完成,如果否,执行与写请求相对应的写操作; 并且在要迁移的虚拟磁盘中的所有数据块被复制到目的地存储设备之后,停止数据迁移,并将虚拟磁盘从源存储设备切换到目的地存储设备。

    • The invention discloses a solar photovoltaic junction box assembly having a housing having a housing body and a housing cover, a cable extending into the housing body and joined to the housing body, and an electrical connector disposed in the housing body and including at least a metal piece electrically connected to a solar cell and a terminal electrically connected to the cable, wherein a chamber for filling gel therein is formed between the terminal and the joint of the cable with the housing body. A part of the cable extending into the housing is fixed to and sealed in the housing by filling gel in the chamber, and first and second over-molded structures can further prevent the cable from being loosened relative to the housing of the junction box, and further prevent water from entering into the housing of the junction box.

    • A system and method for storing data. In one embodiment, a file system includes a hierarchy of nodes partitioned into a plurality of containers. The file system further includes metadata associated with each node. First metadata describes each node's references to other nodes and second metadata identifies each node's parent node. The file system further includes a linkage table associated with each container. Each linkage table comprises entries describing links between a node owned by the associated container and other nodes. In response to detecting that a file system error has occurred, the file system identifies a container which corresponds to the detected error, corrects inconsistencies between the first and second metadata associated with each node owned by the container, and corrects inconsistencies between each of the entries of the linkage table associated with the identified container and the first and second metadata.
    • 一种用于存储数据的系统和方法。 在一个实施例中,文件系统包括被划分成多个容器的节点层级。 文件系统还包括与每个节点相关联的元数据。 第一个元数据描述每个节点对其他节点的引用,第二个元数据标识每个节点的父节点。 文件系统还包括与每个容器相关联的联动表。 每个链接表包括描述由相关联的容器所拥有的节点与其他节点之间的链接的条目。 响应于检测到文件系统错误发生,文件系统识别与检测到的错误相对应的容器,校正与容器所拥有的每个节点相关联的第一和第二元数据之间的不一致性,并且校正每个条目之间的不一致性 与所识别的容器相关联的链接表以及第一和第二元数据。
