    • A frequency conversion correction circuit for an electrophoretic display (EPD) which has a control circuit to capture pixel signals of a next picture and gets a corresponding update signal from a look up table to be output, and a driving circuit to provide a plurality set of potential difference signals corresponding to a plurality set of electrodes of an EPD panel according to the update signal. The EPD further has an environment detection device and a duty frequency judgment unit. The environment detection device detects the operation environments of the EPD and gets an environment parameter. The duty frequency judgment unit compares the preset signal value sections where the environment parameter is located and generates a duty frequency signal and sends to the driving circuit. The driving circuit changes and outputs the frequency of the potential difference signals in a fixed frame time according to the duty frequency signal.
    • 一种用于电泳显示器(EPD)的频率转换校正电路,其具有控制电路,用于捕获下一个图像的像素信号,并获得来自查询表的相应更新信号以输出;以及驱动电路,提供多组 根据更新信号对应于EPD面板的多组电极的电位差信号。 EPD还具有环境检测装置和占空频率判定单元。 环境检测设备检测EPD的操作环境并获取环境参数。 占空频率判断单元将环境参数所在的预置信号值区间进行比较,生成占空比频率信号,发送给驱动电路。 驱动电路根据占空比频率信号在固定帧时间改变并输出电位差信号的频率。

    • A folding treadmill includes a tread base supported by a foot structure which has guide plates formed with elongated slots on two sides of the tread base. The tread base is connected pivotally on the base support through pivot members which are mounted movably within the respective slots so that the tread base is turnable between a folded position and an unfolded position and movable rearward when the tread base turns to the folded position or forward when the tread base turns to the unfolded position. The foot structure further includes a guide rail structure on two sides of the tread base to support movably a first roller which is attached to the tread base and a lifting device for lifting the tread base.
    • 折叠跑步机包括由脚结构支撑的胎面基部,其具有在胎面基部的两侧上形成有细长狭槽的导向板。 胎面基座通过可移动地安装在各个槽内的枢转构件枢转地连接在基座支撑件上,使得胎面基座可在折叠位置和展开位置之间转动,并且当胎面基部转动到折叠位置或向前时可向后移动 当胎面基座转到展开位置时。 足部结构还包括在胎面基部的两侧上的导轨结构,以可移动地支撑附接到胎面基部的第一辊和用于提升胎面基部的提升装置。
