    • A laser engraving mechanism (100) for engraving a workpiece (16) includes an image receiver (12), an image processor (13), an engraving controller (14), and a laser emitting member (15). The image receiver screens the workpiece to form an image of the workpiece and transforms the image of the workpiece into electronic image signals. The image processor is connected to the image receiver. The image processor saves a group of datum coordinates, forms a group of engraving coordinates according to the electronic image signals, and compares the engraving coordinates with the datum coordinates. The engraving controller is connected to the image processor. The laser emitting member is connected to the engraving controller, and the engraving controller instructs the laser emitting member to engrave the workpiece based on a comparison of results between the engraving coordinates and the datum coordinates.
    • 用于雕刻工件(16)的激光雕刻机构(100)包括图像接收器(12),图像处理器(13),雕刻控制器(14)和激光发射部件(15)。 图像接收器屏蔽工件以形成工件的图像,并将工件的图像转换为电子图像信号。 图像处理器连接到图像接收器。 图像处理器保存一组基准坐标,根据电子图像信号形成一组雕刻坐标,并将雕刻坐标与基准坐标进行比较。 雕刻控制器连接到图像处理器。 激光发射构件连接到雕刻控制器,并且雕刻控制器基于对雕刻坐标和基准坐标之间的结果进行比较,指示激光发射构件对工件进行雕刻。

    • A method and an apparatus for altering a key function of a software input panel (SIP) of an electronic device and a recording medium thereof are provided, wherein the SIP includes a plurality of keys, and the number and layout of the keys are fixed. In the present method, first, an operating interface of an electronic device is switched, wherein the operating interface includes the SIP. Then, each key of the SIP is switched to an input word corresponding to the operating interface. As a result, the input word corresponding to each key of the SIP is automatically altered according to the current operating interface, and accordingly inputting through the SIP is made very convenient.
    • 提供了一种用于改变电子设备的软件输入面板(SIP)的键功能的方法和装置及其记录介质,其中SIP包括多个键,并且键的数量和布局是固定的。 在本方法中,首先切换电子设备的操作界面,其中操作界面包括SIP。 然后,将SIP的每个密钥切换到与操作界面对应的输入字。 结果,根据当前操作界面自动地改变与SIP的各个密钥对应的输入字,因此通过SIP的输入非常方便。

    • A projection system and a light tunnel applied in the projection system. The light tunnel comprises a first reflector, a second reflector, a third reflector, a fourth reflector, a light entrance, and a light exit. A distance between the third and fourth reflectors gradually changes from the light entrance to the light exit. The distance between the third and fourth reflectors at the light entrance and the light exit is less than length of each of the first and second reflectors. Thus, the light tunnel can be easily held and applied to various projection systems using various light sources and image generation devices.
    • 在投影系统中应用的投影系统和光通道。 光通道包括第一反射器,第二反射器,第三反射器,第四反射器,光入口和光出口。 第三和第四反射器之间的距离从光入射到光出口逐渐变化。 在光入口和光出口处的第三和第四反射器之间的距离小于第一和第二反射器中的每一个的长度。 因此,可以使用各种光源和图像生成装置容易地将光通道保持并应用于各种投影系统。
