    • An Ethernet physical layer (PHY) module is provided with a method for transceiving between a 10GBASE-R client interface and a 100G attachment interface. On each of ten client interface logical lanes a 10GBASE-R signal is accepted. Each 10GBASE-R logical lane is demultiplexed into two 5 gigabit per second (Gbps) pseudo 100GBASE-R logical lanes, creating a total of twenty pseudo 100GBASE-R logical lanes. The pseudo 100GBASE-R logical lanes are arranged into n groups of 20/n pseudo 100GBASE-R logical lanes. Further, the pseudo 100GBASE-R logical lanes from each group are arranged into a 100G attachment logical lane. Finally, a 100G attachment logical lane is transmitted at an attachment interface on each of n physical lanes. In the reverse direction, each of n physical lanes accepts a 100G attachment logical lane at the attachment interface, and a de-aggregation process supplies a 10GBASE-R signal on each of ten client interface logical lanes.
    • 以太网物理层(PHY)模块提供了一种用于在10GBASE-R客户端接口和100G附件接口之间进行收发的方法。 在10个客户端界面逻辑通道中的每一个上接受10GBASE-R信号。 每个10GBASE-R逻辑通道被解复用为两个5千兆位/秒(Gbps)伪100GBASE-R逻辑通道,共创建了20个伪100GBASE-R逻辑通道。 伪100GBASE-R逻辑通道被排列成n组20 / n个伪100GBASE-R逻辑通道。 此外,来自每组的伪100GBASE-R逻辑通道被排列成100G附件逻辑通道。 最后,在n个物理通道中的每一个上的附着接口上发送100G附件逻辑通道。 在相反的方向上,n个物理通道中的每一个在附接接口处接受100G的连接逻辑通道,并且去聚合处理在十个客户端接口逻辑通道中的每一个上提供10GBASE-R信号。

    • A system and method are provided for transporting a serial stream via a lower speed network using multiple parallel paths. At a transmitter, an optical or electromagnetic waveform is accepted representing a serial stream of digital information, and unbundled into n virtual information streams. Each virtual information stream is divided into a sequence of segments. Each segment is encapsulated, creating a sequence of packets by adding a start indicator to the beginning of each segment, and a terminate indicator to the end of each segment. Each packet is disinterleaved across m lanes and reinterleaved into n branches of framed data. Optical or electromagnetic waveforms representing the framed data are transmitted via n network branches. A receiver is also provided, which essentially reverses the above-described transmission method.
    • 提供了一种用于通过使用多个并行路径的低速网络传送串行流的系统和方法。 在发射机处,接收表示数字信息的串行流的光学或电磁波形,并将其分解成n个虚拟信息流。 每个虚拟信息流被分成一段段。 每个段被封装,通过将开始指示符添加到每个段的开始,并且将终止指示符添加到每个段的末尾来创建数据包序列。 每个数据包在m个通道上解交错,并重新交织成成帧数据的n个分支。 通过n个网络分支传送表示成帧数据的光学或电磁波形。 还提供接收机,其基本上反转了上述传输方法。

    • A pipe handling assembly includes a pipe engaging apparatus having a pipe gripping mechanism connectable to a top drive such that the top drive transmits rotational movement and axial movement to the pipe gripping mechanism. A pipe handling device is mounted onto the pipe engaging apparatus, the pipe handling device including a link hanger mounted on the pipe engaging apparatus. A link arm has a first end pivotally connectable to the link hanger and an outboard end selected to carry a pipe into a position to be gripped by the pipe engaging apparatus. A bearing isolates rotational movement to the pipe gripping mechanism from the link hanger. A connection rigidly connects the link hanger to the pipe engaging apparatus during operation of the pipe handling assembly. The connection is selected to substantially prevent the link hanger from rotating with the pipe gripping mechanism should the bearing seize.
    • 管道处理组件包括管接合装置,其具有可连接到顶部驱动器的管夹持机构,使得顶部驱动器将旋转运动和轴向运动传递到管道夹持机构。 管道处理装置安装在管道接合装置上,管道处理装置包括安装在管道接合装置上的连接悬挂器。 连杆臂具有可枢转地连接到连杆悬挂器的第一端和被选择用于将管道运送到被管接合装置夹持的位置的外侧端。 轴承将连杆悬挂器的旋转运动与管夹持机构隔离开。 在管道处理组件的操作期间,连接件将连杆架连接到管接合装置。 如果轴承卡住,连接被选择为基本上防止连杆架与管夹持机构一起旋转。
