    • A method for designing and fabricating lens unit comprises the steps of: establishing a set of known parameter values of a properly focused lens unit; inputting an image height desired; calculating a corresponding lens wall thickness and an air gap based on the image height inputted; and designing and fabricating a new lens unit based on the calculated lens wall thickness and air gap to accord with the image height inputted. As such, the present invention only needs to alter the wall thickness and air gap of optical lens to obtain different image heights. The alteration of wall thickness is achieved by adjusting the space between the male and female parts of the mold assembly; the alteration of air gap is achieved by providing a pad of predetermined thickness on the optical lens without the need to redesign the mold assembly for the fabrication of optical lens.
    • 一种用于设计和制造透镜单元的方法包括以下步骤:建立一组适当聚焦透镜单元的已知参数值; 输入所需的图像高度; 基于输入的图像高度计算相应的透镜壁厚和气隙; 并且基于计算出的透镜壁厚和气隙来设计和制造新的透镜单元以符合输入的图像高度。 因此,本发明仅需要改变光学透镜的壁厚和气隙,以获得不同的图像高度。 通过调整模具组件的阳部件和阴部件之间的空间来实现壁厚的改变; 通过在光学透镜上提供预定厚度的垫而不需要重新设计用于制造光学透镜的模具组件来实现气隙的改变。

    • The present invention relates generally to a fastener module for portable computers that is disposed on the host of a portable computer to fasten the LCD with the host of the portable computer, no matter whether the LCD of the portable computer is closed directly or after rotating 180 degrees; the fastener module has a pivotable eccentric hook rod with a normal horizontal position under the effect of an elastic component when not being affected by magnetic effect, when the LCD closes on the host of the computer, both sides of the hook rod are affected by the magnetic effect of the magnetic component on the LCD; since the pivot of the hook rod is designed eccentrically, the magnetic moment generated by the magnetic effect for each side of the hook rod is different, so that the hook rod changes it position instantly from normal horizontal state to vertical state and hooks in the opening of the LCD to fasten the LCD onto the host of the portable computer.
    • 本发明一般涉及一种用于便携式计算机的紧固件模块,其设置在便携式计算机的主机上,以便与便携式计算机的主机紧固LCD,无论便携式计算机的LCD是直接关闭还是在旋转180之后 度; 紧固件模块具有可旋转的偏心钩杆,当不受磁效应影响时,在弹性部件的作用下具有正常水平位置,当LCD在主机上关闭时,钩杆的两侧受到 磁性元件对液晶显示器的磁效应; 由于钩杆的枢轴设计为偏心,因此钩杆每侧的磁效应产生的磁矩不同,因此钩杆从正常的水平状态立即将其立场改变为垂直状态,并在开口中钩住 的LCD将LCD固定到便携式计算机的主机上。

    • A driving device is provided for a cathode fluorescent lamp (CCFL) circuit, comprising a voltage generator outputting a driving voltage and a controller coupled thereto. The controller directs the voltage generator to output a first voltage exceeding a working voltage of the CCFL to initialize the CCFL. When brightness of the cold cathode lamp tube exceeds a working brightness of the CCFL, the controller directs the voltage generator to decrease the driving voltage gradually so that the brightness of the CCFL equals the working brightness. The controller stops decreasing the driving voltage when the driving voltage equals the working voltage.
    • 提供了一种用于阴极荧光灯(CCFL)电路的驱动装置,包括输出驱动电压的电压发生器和耦合到其上的控制器。 控制器引导电压发生器输出超过CCFL工作电压的第一电压,以初始化CCFL。 当冷阴极灯管的亮度超过CCFL的工作亮度时,控制器引导电压发生器逐渐降低驱动电压,使得CCFL的亮度等于工作亮度。 当驱动电压等于工作电压时,控制器停止降低驱动电压。
