    • A method for communicating with a downhole tool located in a subterranean borehole is disclosed. Exemplary embodiments of the method include encoding data and/or commands in a sequence of varying drill string rotation rates and drilling fluid flow rates. The varying rotation rates and flow rates are measured downhole and processed to decode the data and/or the commands. In one exemplary embodiment, commands in the form of relative changes to current steering tool offset and tool face settings are encoded and transmitted downhole. Such commands may then be executed, for example, to change the steering tool settings and thus the direction of drilling. Exemplary embodiments of this invention advantageously provide for quick and accurate communication with a downhole tool.
    • 公开了一种与位于地下钻孔中的井下工具进行通信的方法。 该方法的示例性实施例包括以变化的钻柱旋转速率和钻井液流速的顺序编码数据和/或命令。 在井下测量变化的旋转速率和流速,并进行处理以对数据和/或命令进行解码。 在一个示例性实施例中,以当前转向工具偏移和工具面设置的相对变化形式的命令被编码并在井下传送。 然后可以执行这样的命令,例如,改变转向工具的设置,从而改变钻孔的方向。 本发明的示例性实施例有利地提供了与井下工具的快速和准确的通信。

    • An overlapping or nesting connector is provided for connecting adjacent edge restraint sections. The edge restraint includes a substantially upright section and a base section, and may include braces-extending between the upright section and the base section. The connector may be formed integrally with or separate from the edge restraint sections, and includes at least an upper wall, and optionally lateral walls and/or a rear wall. The upper wall may define an opening for a spike, and the brace or coupling structure with which the connector overlaps may define a corresponding opening for receiving the spike, which openings are aligned when the connector overlaps the brace. After adjacent edge restraints have been connected via the overlapping connector/brace, the spike is driven through the aligned openings into the underlying surface to provide a strong connection between the adjacent edge restraints and between the edge restraints and the underlying surface.
    • 提供重叠或嵌套连接器用于连接相邻的边缘约束部分。 边缘约束包括基本上直立的部分和基部,并且可以包括在直立部分和基部之间延伸的支架。 连接器可以与边缘约束部分一体形成或与边缘约束部分分离,并且至少包括上壁和任选的侧壁和/或后壁。 上壁可以限定用于钉的开口,并且连接器重叠的支架或联接结构可以限定用于接收钉的对应开口,当连接器与支架重叠时,该开口对准。 在相邻的边缘约束通过重叠的连接器/支架连接之后,尖钉被驱动通过对准的开口进入下面的表面,以在相邻的边缘约束之间以及在边缘约束和下面的表面之间提供牢固的连接。

    • Landscaping support apparatus is provided which includes substantially vertical strip restraining elements for defining a boundary around hard surface elements. The vertical strip restraining elements include an inner surface facing toward the hard surface elements for receiving substantially horizontal forces from the hard surface elements. Horizontal extension elements are provided which extend out from an outer surface of the vertical strip restraining elements in at least the lower region of the upright strip restraining elements for receiving vertical forces relative to the ground surface. Force converting elements are provided for converting the horizontal forces received by the vertical strip restraining elements into vertical forces against the horizontal extension elements, thereby restraining the hard surface elements in the boundary. Attaching elements are provided which permit a detachable mounting of at least one of the horizontal extension elements and the force converting elements to the vertical strip restraining elements.
    • 提供景观美化支持装置,其包括用于限定硬表面元件周围的边界的基本垂直的条带限制元件。 垂直条限制元件包括面向硬表面元件的内表面,用于从硬表面元件接收基本上水平的力。 提供了水平的延伸元件,其在直立条限制元件的至少下部区域中从垂直条限制元件的外表面延伸,用于接收相对于地面的垂直力。 提供力转换元件用于将由垂直带限制元件接收的水平力转换成垂直于水平延伸元件的力,从而限制边界中的硬表面元件。 提供了附接元件,其允许将水平延伸元件和力转换元件中的至少一个可拆卸地安装到垂直条限制元件。

    • One embodiment of the present invention sets forth a technique for emitting coherent output from multiple threads for the printf( ) function. Additionally, parallel (not divergent) execution of the threads for the printf( ) function is maintained when possible to improve run-time performance. Processing of the printf( ) function is separated into two tasks, gathering of the per thread data and formatting the gathered data according to the formatting codes for display. The threads emit a coherent stream of contiguous segments, where each segment includes the format string for the printf( ) function and the gathered data for a thread. The coherent stream is written by the threads and read by a display processor. The display processor executes a single thread to format the gathered data according to the format string for display.
    • 本发明的一个实施例提出了一种用于从printf()函数的多个线程发射相干输出的技术。 另外,为了提高运行时性能,可以维护printf()函数的线程的并行(不发散)执行。 printf()函数的处理分为两个任务,每个线程数据的收集和格式化收集的数据根据​​显示的格式代码。 线程发出连续段的相干流,其中每个段包括printf()函数的格式字符串和线程收集的数据。 相干流由线程写入并由显示处理器读取。 显示处理器根据用于显示的格式字符串执行单个线程以格式化收集的数据。

    • One embodiment of the present invention sets forth a technique that allows multiple producers and/or consumers to access a first-in first-out sub-system (FIFO) using a “lock-free” mechanism. When two or more producers attempt to push data onto the FIFO simultaneously, only one of the producers succeeds. Similarly, when two or more consumers attempt to pop data from the FIFO simultaneously, only one of the consumers succeeds. However, each producer and consumer is provided with an indication of whether their respective access was successful. Unsuccessful accesses may be retried in the following clock cycle, so that simultaneous accesses are serialized.
    • 本发明的一个实施例提出了允许多个生产者和/或消费者使用“无锁”机制来访问先进先出子系统(FIFO)的技术。 当两个或多个生产者尝试将数据同时推送到FIFO时,只有一个生产者成功。 类似地,当两个或多个消费者尝试同时从FIFO弹出数据时,只有一个消费者成功。 然而,每个生产者和消费者都被提供了他们各自的访问是否成功的指示。 可能会在以下时钟周期重试不成功的访问,以便同时访问被序列化。
