    • A fast handoff method of an Access Router includes receiving and storing at an Access Point a Router Advertisement message periodically sent from the Access Router to which the Access Point is connected, the Access Point being connected to at least one mobile node in wireless manner and supporting services to the at least one mobile node; generating at least one Care-of Address (CoA) at the Access Point, performing Duplicate Address detection, and storing the CoAs for which the Duplicate Address detection is successfully completed; forming, when a new mobile node enters a service-available range of the Access Point, a link to the new mobile node at the Access Point, including any of the stored CoAs in the Router Advertisement message, and sending the Router Advertisement message including the stored CoA to the new mobile node; and communicating the new mobile node to a network using the CoA included in the sent Router Advertisement message.
    • 接入路由器的快速切换方法包括在接入点处接收和存储从接入点连接到的接入路由器周期性地发送的路由器通告消息,接入点以无线方式连接到至少一个移动节点并且支持 至少一个移动节点的服务; 在接入点生成至少一个转交地址(CoA),执行重复地址检测,并存储成功完成重复地址检测的CoA; 当新的移动节点进入接入点的服务可用范围时,形成到接入点处的新移动节点的链路,包括路由器通告消息中存储的任何一个CoA中的任何一个,以及发送包括 将CoA存储到新的移动节点; 以及使用所发送的路由器通告消息中包括的CoA将新的移动节点传送到网络。

    • A pipeline cleaning and renovating method of the present invention comprises introduction of abrasive particulates by pressurized air through the pipelines to remove the incrustation adhering to the inner surface of the pipelines. Water or other liquids are introduced into the pipelines to generate or increase a moisture content in a flow of the pressurized air. The air flow through the pipelines is controlled to induce a substantially helical flow pattern such that a substantial amount of abrasive particulates are driven by the air flow to move along the inner surface of the pipeline in order to efficiently remove the incrustation. After the pipelines are cleaned, a coating material is added into the pipelines and driven by the air flow in the substantially helical flow pattern to provide an even coating film on the cleaned inner surface of the pipelines. This method can be broadly applied to various types of pipelines and various diameters of the pipelines from 13 mm to 300 mm. The length of the pipeline being cleaned at one time can be from several hundred meters to more than one kilometer, depending on the type of pipeline.
    • 本发明的管道清洗和更新方法包括通过管道引入加压空气的磨料颗粒以去除附着在管道内表面上的结垢。 将水或其它液体引入管道中以产生或增加加压空气流中的含水量。 通过管道的空气流被控制以引起基本上螺旋的流动模式,使得大量的磨料颗粒被空气流驱动以沿着管道的内表面移动,以有效地去除结垢。 在管道被清洁之后,将涂料添加到管道中并由基本上螺旋状流动图案中的空气流驱动,以在管道的净化内表面上提供均匀的涂膜。 该方法可广泛应用于各种类型的管道和管道的各种直径从13mm到300mm。 根据管道类型,一次清洁的管道的长度可以从几百米到一公里以上。
