    • A dynamic time sequence control device and its method for a word matching circuit. The word matching circuit includes a first switch connected between an input voltage and a node to respond to a control signal generated by a pre-charging circuit so that within a pre-charging phase period a current is generated to flow through a capacitor to generate a charging voltage. The node is connected to multiple data memories and matching circuits so that the matching result can be outputted through the node. The dynamic time sequence control device includes a second switch connected between the first switch and the node. A third switch is connected between the data memory and matching circuit and a self time sequence controller has a threshold value to respond to the control signal and to conduct the second switch and turn off the third switch during the pre-charging phase period, meanwhile, it turns off the second switch and conducts the third switch when the charging voltage is detected to be larger than threshold value. The self time sequence controller detects the output voltage of the node and outputs the data matching result during a value-acquisition phase period.

    • The invention provides a fiber-optic sensing system for measuring a curvature in a small and elongated cavity of an object. The system includes a light source, an optical fiber and a light signal reflecting device disposed at a distal end of the optical fiber. The optical source emits a light signal into the optical fiber. The distal section of the optical fiber is inserted into the cavity of the object which curvature is to be measured. The curvature of the cavity bends the distal section of the optical fiber so that attenuation of light signal transmitting through the distal section occurs. This attenuated signal is reflected by a reflecting device and coupled into a measuring device. Thereby the curvature is deduced in accordance with the amount of energy attenuation in the reflected light signal.
    • 本发明提供了一种用于测量物体的小而细长的空腔中的曲率的光纤传感系统。 该系统包括设置在光纤远端的光源,光纤和光信号反射装置。 光源将光信号发射到光纤中。 将光纤的远端插入物体的要测量的曲率的空腔中。 空腔的曲率使光纤的远端部分弯曲,从而发生通过远端部分传输的光信号的衰减。 该衰减信号由反射装置反射并耦合到测量装置中。 因此,根据反射光信号中的能量衰减量来推导曲率。
