摘要： A backlight system for use in display devices including liquid crystal displays, or in advertising means or in lighting devices includes one or more light sources, a light-glide panel, a light reflecting film, an anisotropic light diffusing film, and a light collimating film. A light source is positioned at one or more edges of the light-guide panel in a predetermined direction. A light reflecting film is placed below the light-guide panel. An anisotropic light diffusing film is placed over the light-guide panel. The anisotropic light diffusing film has directionally different diffusing properties. The light collimating film has a top surface and a smooth bottom surface. The top surface of the light collimating film includes a lenticular layer extending in a predetermined direction. The lenticular layer has a plurality of linear prisms. A reflective polarizer can be employed over the light collimating film.

摘要： A way of a synthesizing speech by the combination of a Speech coding mode and Formant analysis mode is achieved by segmenting a Formant transition region into portions, according to the linear characteristics of a frequency curve, and storing the Formant information of each portion. Therefrom frequency information of a sound is obtained. Formant information data of a Formant contour to produce speech, is calculated by a linear interpolation method. The frequency and the bandwidth, which are elements of the Formant contour calculated by a linear interpolation method, are sequentially filtered in order to produce a speech signal which is a digital speech signal. The digital speech signal is converted to an analog signal, amplified, and output through a external speaker.
摘要翻译：通过语音编码模式和共振峰分析模式的组合来合成语音的方法是通过根据频率曲线的线性特征将共振峰过渡区域分割成部分并存储每个部分的共振峰信息来实现的。从中获得声音的频率信息。通过线性插值法计算生成语音的共振峰轮廓的共振峰信息数据。通过线性插值方法计算的作为常态轮廓的元素的频率和带宽被顺序地滤波，以产生作为数字语音信号的语音信号。数字语音信号被转换为模拟信号，经过外部扬声器放大并输出。
