    • Methods and systems for drilling subsea wells bores with dual-gradient mud systems include drilling the subsea well bore while employing a subsea pumping system, a subsea choke manifold and one or more mud return risers to implement the dual gradient mud system. When a well bore influx is detected, the well bore is shut in, and components determine if pressure control may be used to circulate the influx out of the well bore, the size of the influx, and how much the mud system weight will need to be reduced to match the dual gradient hydrostatic head before the influx reaches the subsea pump take point. The subsea pumping system, subsea choke manifold, and mud risers are isolated while the influx is circulated up one or more fluid passages in the drilling riser package using the surface pump, through the wellhead, and out the surface choke manifold.
    • 用双梯度泥浆系统钻探海底井的方法和系统包括钻井海底井,同时采用海底泵送系统,海底扼流圈和一个或多个泥浆回流提升器来实施双梯度泥浆系统。 当检测到井眼流入时,关闭井眼,并且组件确定是否可以使用压力控制来循环流出井眼,流入的大小以及泥浆系统重量将需要多少 在流入到海底泵取点之前,减小到匹配双梯度静水压头。 海底泵送系统,海底扼流器歧管和泥浆提升管被隔离,同时利用表面泵通过井口和表面扼流圈将流入循环到钻井立管包装中的一个或多个流体通道。

    • A wireless network for supporting mobile unit traffic segmentation for a plurality of mobile units to associate each mobile unit with virtual networking services (VNS). The wireless network includes a plurality of radio units and access controllers. Each radio unit is adapted to initiate the connection of a mobile unit to the network by transmitting and receiving communication data to and from the mobile unit. Each access controller is adapted to receive communication data from each radio unit during the connection of a mobile unit. Based on the communication data transmitted to the radio unit during connection of the mobile unit, access controller is able to discover VNS factors for the mobile unit communication session and to establish a communication session based on the VNS factors discovered during the connection process such that the mobile unit is connected to the network on the basis of the characteristics defined by the virtual networking services.
    • 一种用于支持多个移动单元的移动单元业务分段以将每个移动单元与虚拟网络服务(VNS)相关联的无线网络。 无线网络包括多个无线电单元和接入控制器。 每个无线电单元适于通过向移动单元发送和从移动单元接收通信数据来发起移动单元与网络的连接。 每个访问控制器适于在移动单元的连接期间从每个无线电单元接收通信数据。 基于在移动单元的连接期间发送到无线电单元的通信数据,访问控制器能够发现用于移动单元通信会话的VNS因子,并且基于在连接过程期间发现的VNS因素来建立通信会话,使得 移动单元根据虚拟网络服务定义的特性连接到网络。

    • A method is taught for providing a reference video signal to a video display through a video interface from a video display adapter for a host computer. The method includes the step of providing a horizontal sync line to carry a horizontal sync signal that occupies pre-defined time intervals as a representation of a horizontal sync pulse. Another step is signaling to the video display adapter that a reference amplitude pulse will be sent on a video data line. A further step is sending the reference amplitude pulse on a video data line during the pre-determined time intervals when the horizontal sync signal occupies the horizontal sync line.
    • 教导了一种用于通过用于主计算机的视频显示适配器的视频接口向视频显示器提供参考视频信号的方法。 该方法包括提供水平同步线以携带占据预定时间间隔的水平同步信号作为水平同步脉冲的表示的步骤。 另一步是向视频显示适配器发信号通知视频数据线上将发送参考幅度脉冲。 另一步是当水平同步信号占据水平同步线时,在预定的时间间隔期间,在视频数据线上发送参考幅度脉冲。
