    • The welding filter device includes a light sensor, a microprocessor, a liquid crystal display, and a user interface. The light sensor senses light to generate a welding signal and a light source intensity signal. The microprocessor comprises a determining module, a control module, a regulating module, and a storage module. The determining module receives the welding signal and determines whether to activate a welding mechanism. The control module receives the light source intensity signal and outputs a control signal. The liquid crystal display presents a first display status according to the control signal. The user interface is used to generate a setting signal; wherein when the liquid crystal display presents the first display status, the regulating module receives the setting signal to regulate the settings so that the liquid crystal display presents a second display status. Furthermore, a method for controlling the welding filter device is also disclosed herein.
    • 焊接过滤装置包括光传感器,微处理器,液晶显示器和用户界面。 光传感器感测光以产生焊接信号和光源强度信号。 微处理器包括确定模块,控制模块,调节模块和存储模块。 确定模块接收焊接信号并确定是否激活焊接机构。 控制模块接收光源强度信号并输出​​控制信号。 液晶显示器根据控制信号呈现第一显示状态。 用户界面用于生成设置信号; 其中当液晶显示器呈现第一显示状态时,调节模块接收设置信号以调节设置,使得液晶显示器呈现第二显示状态。 此外,本文还公开了一种用于控制焊接过滤装置的方法。

    • The present invention relates to a fan control system. The fan control system includes a first micro controller, a second micro controller and a first logic circuit. The first micro controller provides at least one first control signal. The second micro controller is connected to the first micro controller. The second micro controller detects operational status of the first micro controller, and provides at least one second control signal. The first logic circuit receives the first control signal and the second control signal to process logic operation and to generate at least one driving signal to fan. The fan control system of the invention utilizes two micro controllers, when one of the two micro controllers malfunctions, the first logic circuit allows the other micro controller to continue proper operation of the fan, thereby preventing the problem of insufficient heat dissipation that results from malfunction of the single micro controller of a conventional fan control system.
    • 本发明涉及风扇控制系统。 风扇控制系统包括第一微控制器,第二微控制器和第一逻辑电路。 第一微控制器提供至少一个第一控制信号。 第二微控制器连接到第一微控制器。 第二微控制器检测第一微控制器的操作状态,并提供至少一个第二控制信号。 第一逻辑电路接收第一控制信号和第二控制信号以处理逻辑运算并产生至少一个驱动信号给风扇。 本发明的风扇控制系统利用两个微控制器,当两个微控制器中的一个发生故障时,第一逻辑电路允许另一个微控制器继续正确地操作风扇,从而防止由故障引起的散热不足的问题 的传统风扇控制系统的单个微控制器。

    • A hand-held electronic device with calculation operating functions, including a main body, a plurality of number keys disposed on the main body, a display, and at least M operation keys, is disclosed. The display is used for displaying an operation indicator area, a highlight, and a numeral area. Operation indicator area includes N operator indicators arranged in M directions around the reference point. The highlight is used to indicate the selected operator indicator. Numeral area is used to display various numbers. M operation keys are respectively corresponding to M directions of the operator indicators. As one of the M operation keys is triggered, the highlight shifts along the corresponding direction to choose the operator indicator and to perform the corresponding operating functions.
