    • In a variable torque rate test joint, screw-threaded first and second elements are rotated relative to one another by a tool under test. At least one spring beam is cantilevered over a pivot point to exert an axial force between the first and second elements and the torque rate of the test joint can be varied by moving the pivot point to change the axial force. The first element may be a shaft that is fixed during testing and the second element is a nut rotatably mounted on the shaft, whereby the element rotated by the tool has a minimal moment of inertia. Whichever of the first and second elements is held stationary during the test may be mounted in a hub that is locked during the test but can be rotated at the end of the test to reset the test joint. Measurements may be made of the torque and the rotation angle to derive an actual torque rate of the joint, which allows correction of errors by moving the pivot point.
    • 在可变转矩测试接头中,螺纹的第一和第二元件通过被测工具相对于彼此旋转。 至少一个弹簧梁悬挂在枢轴点上以在第一和第二元件之间施加轴向力,并且可以通过移动枢轴点来改变测试接头的扭矩来改变轴向力。 第一元件可以是在测试期间被固定的轴,并且第二元件是可旋转地安装在轴上的螺母,由此由工具旋转的元件具有最小的惯性矩。 第一和第二元件中的任何一个在测试期间保持固定可以安装在在测试期间被锁定的毂中,但是可以在测试结束时旋转以复位测试接头。 可以测量扭矩和旋转角度以导出接头的实际扭矩率,这允许通过移动枢转点来校正误差。

    • An API can be extended to automatically correlate events based on context. Started events for each context (e.g. threads of execution) are maintained on independent stacks. When an instrumented application starts a new transaction, the API generates a started event. A transaction correlation unit within the API can determine if the new transaction started during a previous transaction. If there is a previous started event on the stack, the new transaction started during the previous transaction. The transaction correlation unit can insert an outbound indicator into the new started event to associate the new transaction and the previous transaction. Then, the new started event can be pushed on the stack.
    • 可以扩展API以根据上下文自动关联事件。 每个上下文(例如执行线程)的事件被保持在独立堆栈上。 当检测到的应用程序启动新的事务时,API会生成一个已启动的事件。 API内的事务关联单元可以确定新事务是否在先前事务中开始。 如果堆栈上存在先前的启动事件,则新事务在上一个事务期间启动。 交易相关单元可以将出站指示符插入到新的开始事件中,以将新交易与先前交易相关联。 然后,可以将新的启动事件推送到堆栈中。
