    • A torsion beam type suspension and a forming method of a torsion beam are disclosed. In the torsion beam type suspension comprising a pair of left and right trailing arms connected to each other through a torsion beam, front ends of the trailing arms being used to mount a vehicle body by using joints, the torsion beam is obtained by forming an overall length of a pipe having a certain wall thickness by using a pressure forming process. In this case, end sections defined at both end portions of the torsion beam have a cross-sectional shape of a hollow oval, a center section defined at a center portion of the torsion beam has a cross-sectional shape of a hollow open loop, and middle sections defined between the center portion and both the end portions of the torsion beam have a cross-sectional shape of a hollow open loop. The loop of the middle sections defines an inner space larger than that defined by the loop of the center section. Further, since the torsion beam can be easily formed by adopting a hydro-forming process, it is possible to achieve high twisting rigidity, bending rigidity, and durability without requiring a torsion bar and reinforcement, which must be inevitably assembled to a conventional torsion beam axle, resulting in a reduction of the number of constitutive elements and the overall weight.

    • An improved mounting structure for a flangeless fuel tank forcibly maintains an air-tightness at joined parts between top and bottom halves of a tank when the fuel tank is welded, thereby reducing the space and weight of the tank. The fuel tank is increased in capacity as much as a space of a flange can be adopted. The mounting structure comprises a top half of a tank protrusively formed at a lower external lateral surface thereof with a plurality of studs, a bottom half of a tank formed with grooves corresponding to the plurality of studs and partially inserted into the lower distal end of the top half of the tank, and fastening members for being fastened to the studs of the top half of the tank so that the top and bottom halves of the tank can be air-tightly welded.
    • 当燃料箱被焊接时，用于无凸缘燃料箱的改进的安装结构强制地保持在罐的顶部和底部半部之间的接合部分处的气密性，从而减小了箱的空间和重量。 燃料箱的容量增加，可以采用法兰的空间。 安装结构包括在其下外侧表面突出形成有多个螺柱的罐的上半部，罐的下半部形成有与多个螺柱相对应的槽并部分地插入到多个螺柱的下部远端中 油箱的上半部分以及用于紧固到罐的上半部的螺柱的紧固构件，使得罐的顶部和底部两半可以气密地焊接。

    • AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.
    • 与通信网络相关联的AP以及期望接触的任何无线设备，根据其中每个无线设备选择与之进行通信的AP的协议来操作。 系统协调器使AP操作，以便将每个无线设备引导到由系统协调器选择的AP。 这具有这样的效果，尽管协议涉及使无线设备进行AP的选择，但在功能上，AP对其进行选择。 在第一种技术中，多个AP共享标识符，系统协调器指示一个特定的AP对无线设备做出响应，从而将无线设备看作“个人小区”。 在第二种技术中，AP每个保持对每个无线设备基本唯一的标识符，系统协调器仅指示一个特定的AP来维护任何特定的无线设备的标识符，从而将无线设备看作“个人AP”。

    • Flows are grouped into flow classes, each of which is assigned flow class treatment rules, which might combine application of both firewall and QoS treatments. When a flow is identified as a member of a flow class, traffic for that flow can be treated according to treatment rules collectively with other flows assigned to that flow class. New flows not already members of an already-defined flow class are examined according to a set of flow class assignment rules, which have the effect of either identifying the proper flow class for that flow, or creating a new flow class for that new flow. For each flow, a first packet determines flow assignment, after which succeeding packets are treated according that flow. For each flow class, a first flow determines flow class assignment, after which succeeding flows are collectively treated according to that flow class.
    • 流被分组为流类，其中每个流被分配流类别处理规则，这可以组合防火墙和QoS处理的应用。 当流被识别为流类的成员时，该流的流量可以根据处理规则与分配给该流类的其他流一起被处理。 新流不是已经定义的流类的成员，根据一组流类别分配规则进行检查，这些规则具有为该流识别适当流类或为该流新建流程类的效果。 对于每个流，第一个分组确定流分配，之后根据该流程处理后续分组。 对于每个流类，第一个流确定流类别分配，之后根据该流类别对后续流进行统一处理。

    • Techniques which prevent rogue devices from continued access to a wireless communication system. A control element directs access points as to which mobile stations to service. Each access point maintains a record of the mobile stations it is servicing. At the direction of the control element, one or more access points send ACK (acknowledgement) messages when hearing messages from a rogue device. When the rogue device sends a message, it expects an ACK message in response, but those additional ACK messages interfere with the responsive ACK message, causing the rogue device to never hear the responsive ACK message. The rogue device assumes its message was not received, so it retries sending of that message. When the rogue device retries sending of its message, the responsive ACK message is similarly interfered with, until the rogue device concludes that its connection has been lost.
    • 防止流氓设备继续访问无线通信系统的技术。 一个控制元件指示接入点，哪些移动台要服务。 每个接入点维护其正在维护的移动台的记录。 在控制元件的方向上，当从流氓设备听到消息时，一个或多个接入点发送ACK（确认）消息。 当流氓设备发送消息时，它期待响应的ACK消息，但是这些附加ACK消息干扰响应的ACK消息，导致流氓设备从不听到响应的ACK消息。 流氓设备假定其消息未被接收，因此重试发送该消息。 当流氓设备重试其消息的发送时，响应的ACK消息被类似地干扰，直到流氓设备断定其连接已经丢失。
