    • An anti-fall device for a window sash comprises a window-sash fixing block, a window-frame fixing block, an elastic metal wire and a pipe. The elastic metal wire connects the window-sash fixing block and the window-frame fixing block. The window-sash fixing block is defined with a through hole into which the pipe is inserted. One end of the elastic metal wire is connected to the window-frame fixing block, and the other end of the elastic metal wire penetrates the through hole in the window-sash fixing block and enters the pipe. The end of the elastic metal wire, which penetrates the through hole, is fixed with a limiting block. The diameter of the limiting block is bigger than that of the through hole. The window-sash fixing block is fixed on the window sash, and the window-frame fixing block is fixed on the window frame.
    • 用于窗框的防坠落装置包括窗框固定块,窗框固定块,弹性金属丝和管。 弹性金属丝连接窗框固定块和窗框固定块。 窗框固定块由管插入其中的通孔限定。 弹性金属丝的一端连接到窗框固定块,弹性金属丝的另一端穿过窗框固定块中的通孔并进入管道。 穿过通孔的弹性金属线的端部用限制块固定。 限制块的直径大于通孔的直径。 窗框固定块固定在窗框上,窗框固定块固定在窗框上。

    • A an engine management system includes a processor (8) in communication with a memory (10) that contains a program memory (28) containing instructions for the processor to implement a knock detection method. The knock detection method involves firstly sampling a torque sensor (4) that is responsive to an engine crankshaft (5). The torque sensor is sampled a number of times during a combustion stroke of one or more of cylinders (18a, . . . 18d) of the engine (16). The sampled sensor values are processed to calculate a rate of change of the torque signal and knocking is deemed to be indicated in the event of the rate of change exceeding a predetermined value. In a preferred embodiment the processor (8) is further programmed to reduce knocking once it has been detected by adjusting one or more of a number of controllers including a fuel injection controller (34), an ignition controller (12), a throttle controller (13) and an exhaust gas recirculation controller (39).
    • 发动机管理系统包括与存储器(10)通信的处理器(8),所述存储器(10)包含程序存储器(28),所述程序存储器包含用于执行爆震检测方法的所述处理器的指令。 敲击检测方法首先对响应于发动机曲轴(5)的扭矩传感器(4)进行采样。 在发动机(16)的一个或多个气缸(18a,... 18d)的燃烧行程期间,对转矩传感器进行多次采样。 处理采样的传感器值以计算转矩信号的变化率,并且在变化率超过预定值的情况下认为爆震被指示。 在优选实施例中,处理器(8)进一步被编程为一旦通过调节多个控制器中的一个或多个来检测到它,包括燃料喷射控制器(34),点火控制器(12),节气门控制器 13)和废气再循环控制器(39)。
