    • A customizing equipment for individualized contact lenses comprises an uniform illumination system, a gray image generation system, a projection optical system, a stage system and an alignment system, among which the uniform illumination system generates uniform parallel illuminative light, which generates gray images through the gray image generator controlled by a computer after going through the gray image generation system according to detection results of aberration of human eyes, and images on the image plane of given radius of curvature with photoresist on the samples' surface, which is fixed on the stage system and adjusted to the correct position through the alignment system, after the gray images are zoomed and the curvature of the image field is corrected through the projection optical system, so that the photoresist on the samples' surface will be exposed according to the gray levels of the gray images, after which the exposed samples are developed and etched to obtain the device with continuous embossment microstructure on the sphere. After the checking and post-processing, this device will result in the individualized contact lenses, which can be worn. This current invention can realizes fast customization of individualized contact lenses.
    • 用于个性化隐形眼镜的定制设备包括均匀照明系统,灰色图像生成系统,投影光学系统,舞台系统和对准系统,其中均匀的照明系统产生均匀的平行照明光,其通过 根据人眼像差的检测结果经过灰度图像生成系统后,由计算机控制的灰度图像发生器,以及固定在台面上的样品表面上的具有光刻胶的给定曲率半径的图像平面上的图像 系统,并通过对准系统调整到正确的位置,在灰度图像变焦后,通过投影光学系统校正图像的曲率,使得样品表面上的光致抗蚀剂将根据灰度级曝光 的灰色图像,然后将曝光的样品显影并蚀刻以获得 在球体上具有连续压花微结构的装置。 检查和后处理后,此设备将导致可佩戴的个性化隐形眼镜。 本发明可实现个性化隐形眼镜的快速定制。

    • An exemplary method for online character recognition of East Asian characters includes acquiring time sequential, online ink data for a handwritten East Asian character, conditioning the ink data to produce conditioned ink data where the conditioned ink data includes information as to writing sequence of the handwritten East Asian character and extracting features from the conditioned ink data where the features include a tangent feature, a curvature feature, a local length feature, a connection point feature and an imaginary stroke feature. Such a method may determine neighborhoods for ink data and extract features for each neighborhood. An exemplary Hidden Markov Model based character recognition system may use various exemplary methods for training and character recognition.
    • 用于东亚字符的在线字符识别的示例性方法包括获取用于手写东亚字符的时间顺序在线墨水数据,调节墨水数据以产生经调节的墨水数据,其中调节的墨水数据包括关于写入东方手写的顺序的信息 亚洲字符和从调节的墨水数据中提取特征,其中特征包括切线特征,曲率特征,局部长度特征,连接点特征和假想笔划特征。 这种方法可以确定墨水数据的邻域并提取每个邻域的特征。 基于示例性的基于隐马尔可夫模型的角色识别系统可以使用用于训练和角色识别的各种示例性方法。
