    • Provided are an apparatus and method for converting a pitch delay using linear prediction in speech transcoding. A linear interpolating portion linearly interpolates a closed-loop pitch delay decoded by a selected mode vocoder (SMV) speech decoder to make the closed-loop pitch delay fit in a search section for open-loop pitch delays of G.723.1 speech encoder, to obtain a changed closed-loop pitch delay of the SMV decoder. A predicted value calculating portion calculates a predicted pitch delay using linear prediction, based on past closed-loop pitch delays of the G.723.1 speech encoder. A difference calculating portion calculates a difference between the changed closed-loop pitch delay of the SMV speech decoder and the calculated predicted pitch delay. When the calculated difference is less than the predetermined threshold value, a pitch delay determining portion determines the changed closed-loop pitch delay of the SMV speech decoder to be an open-loop pitch delay of the G.723.1 speech encoder. A pitch delay detecting portion detects a closed-loop pitch delay of the G.723.1 speech encoder using a conventional method, based on the determined open-loop pitch delay of the G.723.1 speech encoder.
    • 提供了一种用于在语音代码转换中使用线性预测来转换音调延迟的装置和方法。 线性内插部分线性内插由选择的模式声码器(SMV)语音解码器解码的闭环音调延迟,以使闭环音调延迟适合于用于G.723.1语音编码器的开环音调延迟的搜索部分, 获得SMV解码器的改变的闭环音调延迟。 基于G.723.1语音编码器的过去闭环音调延迟,预测值计算部分使用线性预测来计算预测音调延迟。 差分计算部分计算SMV语音解码器的改变的闭环音调延迟与所计算的预测音调延迟之间的差。 当计算出的差小于预定阈值时,音调延迟确定部分将SMV语音解码器的改变的闭环音调延迟确定为G.723.1语音编码器的开环音调延迟。 基于所确定的G.723.1语音编码器的开环音调延迟,音调延迟检测部分使用常规方法检测G.723.1语音编码器的闭环音调延迟。

    • A method and apparatus for DNA purification are provided which use a silicone structure having a Sio2 layer formed on its surface. In the method, DNA is effectively purified from a fluid sample by maintaining the pH of the silicone structure's surface to be lower than the pKa of silanol to make the surface of the silicone structure charged with hydroxyl groups which results in the binding of DNA present in the fluid sample, removing the residual fluid sample which fails to bind to the surface of the silicone structure, and altering the pH of the silicone structure's surface to be higher than the pKa of silanol to separate the bound DNA from the surface of the silicone structure.
    • 提供一种用于DNA纯化的方法和装置,其使用在其表面上形成有SiO 2层的硅氧烷结构。 在该方法中,通过将硅氧烷结构的表面的pH保持在低于硅烷醇的pKa,从流体样品中有效地纯化DNA,以使带有羟基的硅氧烷结构的表面导致DNA存在的结合 流体样品,去除不能结合到硅氧烷结构表面的残留流体样品,并且改变硅氧烷结构表面的pH高于硅烷醇的pKa以将结合的DNA与硅氧烷结构的表面分离 。

    • In a Video Cassette Recorder (VCR) system capable of receiving broadcast signals, the still images extracted from the broadcast signals are stored in a memory area at regular intervals when the broadcast signals are recorded on a videotape. When a user requests a search for a wanted playback start position, a snapshot set screen on which the still images stored at regular intervals are arranged in an N×N or an N×M matrix form is provided to a display unit. When the user selects a specific snapshot image among the snapshot images on the snapshot set screen as a jump position, a playback mode is automatically performed by jumping to the jump position. Accordingly, the wanted playback start position can be searched for and a playback operation is performed from the wanted playback start position conveniently and speedily.
    • 在能够接收广播信号的视频录像机(VCR)系统中,当将广播信号记录在录像带上时,从广播信号提取的静止图像以规则的间隔存储在存储区域中。 当用户请求搜索想要的回放开始位置时,以N×N或N×M矩阵形式排列以规则间隔存储静止图像的快照设置屏幕被提供给显示单元。 当用户在快照设置屏幕上的快照图像之中选择特定快照图像作为跳转位置时,通过跳转到跳转位置来自动执行重放模式。 因此,可以方便,快速地从想要的回放开始位置搜索想要的回放开始位置并进行回放操作。
