    • An orienting apparatus including at least one housing element configured to couple with a drill string; an actuator disposed inside the at least one housing element; a nozzle coupled to the actuator; a torque generator coupled to the actuator and extending axially downward through the at least one housing, wherein the torque generator is configured to rotate in a first direction as it moves downward; a mandrel coupled to the torque generator; and a stroke adjuster at least partially disposed in an upper end of the mandrel, wherein rotation in the first direction is caused by an increase in differential pressure is disclosed.
    • 一种定向装置,包括配置成与钻柱联接的至少一个壳体元件; 致动器,设置在所述至少一个壳体元件内; 联接到致动器的喷嘴; 扭矩发生器,其联接到所述致动器并且轴向向下延伸通过所述至少一个壳体,其中所述扭矩发生器构造成在其向下移动时沿第一方向旋转; 联接到扭矩发生器的心轴; 以及至少部分地设置在所述心轴的上端中的行程调节器,其中,所述第一方向上的旋转是由压力差的增加引起的。

    • A method and system of indexing into trace data based on entries in a log buffer. At least some of the illustrative embodiments are methods comprising executing a traced program on a target device. The traced program writes entries to a log buffer within the target device, and the traced program also contemporaneously writes an index value for each entry to a register. The index value written to the register becomes part of trace data regarding the traced program and correlates each entry to a respective portion of the trace data. Using the information one may either or both: display on a display device a portion of the trace data (the portion selected based on selecting an entry from the log buffer); or display on the display a portion of the log buffer (the portion selected based on selecting an entry from the trace data).
    • 根据日志缓冲区中的条目将索引数据进行索引的方法和系统。 说明性实施例中的至少一些是包括在目标设备上执行跟踪的程序的方法。 跟踪的程序将条目写入目标设备中的日志缓冲区,并且跟踪的程序同时将每个条目的索引值写入寄存器。 写入寄存器的索引值成为跟踪程序的跟踪数据的一部分,并将每个条目与跟踪数据的相应部分相关联。 使用该信息可以一个或两者:在显示设备上显示跟踪数据的一部分(基于从日志缓冲器中选择条目而选择的部分); 或在显示器上显示日志缓冲区的一部分(基于从跟踪数据中选择条目而选择的部分)。
