    • A method and apparatus for measuring effects of various conditions on deposit build up in an exhaust gas recirculation system. The apparatus includes a testing jig having a main branch, a test branch, and a control branch. The test and control branches are connected, at an inlet and outlet, to the main branch. Each branch includes a flow control valve so that fluid flow through the test branch can be equalized with fluid flow through the control branch. A parameter of interest, such as temperature, oil, or humidity, in the test branch is modified, and the jig is connected to an engine exhaust, and the flows are equalized. Pressures and temperatures at various points in the jig are monitored and, after a predetermined period of time or when a pressure drop is sensed, the test is complete and the deposits in the test branch are compared with those in the control branch to determine the effect of the altered parameter.
    • 用于测量各种条件对排气再循环系统中沉积物积聚的影响的方法和装置。 该装置包括具有主分支,测试分支和控制分支的测试夹具。 测试和控制分支在入口和出口连接到主分支。 每个分支包括流量控制阀,使得通过测试分支的流体流动可以与通过控制分支的流体流量相等。 在试验分支中,诸如温度,油或湿度的关注参数被修改,并且夹具连接到发动机排气口,并且流量相等。 对夹具各点的压力和温度进行监控,在预定时间段或感测到压降后,测试完成,将测试分支中的沉积物与控制分支中的沉积物进行比较,以确定效果 的改变参数。

    • In a handheld computing device that includes a backlit display having a variable-intensity backlight, a method for controlling the intensity of light produced by the backlight involves the following steps. The computing device also includes user data input means, and data processing means coupled to the user data input means and the backlit display. The data processing means includes at least one software application that is configured to display information on the display. The method involves the steps of (1) setting the intensity to a first intensity level and activating one of the software applications; and (2) setting the intensity to a minimum intensity level, less than the first intensity level, after expiry of a predetermined elapsed time of non-activity from the user data input means. The predetermined elapsed time is based on the activated software application.
