    • The present invention relates to an apparatus and method for localizing a sound source in real time. The apparatus for localizing a sound source in real time includes a sound signal acquisition unit for acquiring sound signals through two or more channels. A sample delay storage unit stores a plurality of pieces of data, sampled from the sound signals acquired through respective channels, for a predetermined period of time. A correlation calculation unit calculates correlations between the channels from the plurality of pieces of sampled data stored in the sample delay storage unit. A sound source direction calculation unit calculates an azimuth angle of the sound source using both the correlations between the channels and location relationships of the sound signal acquisition unit. Accordingly, the present invention can localize a sound source in real time.
    • 本发明涉及实时定位声源的装置和方法。 用于实时定位声源的装置包括用于通过两个或更多个声道获取声音信号的声音信号获取单元。 采样延迟存储单元存储从通过各个通道获取的声音信号中采样的多条数据,预定时间段。 相关计算单元计算来自存储在采样延迟存储单元中的多条采样数据的信道之间的相关性。 声源方向计算单元使用声道和声音信号获取单元的位置关系之间的相关性来计算声源的方位角。 因此,本发明可以实时定位声源。

    • Disclosed is an electrophoretic display (EPD) device capable of delaying or preventing a sealant from leaking down by forming a dam pattern prior to a sealing process using the sealant, and a method for fabricating the same. The EPD device comprises: gate lines and data lines crossing each other to define a pixel region, and formed on a lower substrate; a thin film transistor (TFT) electrically connected to the gate lines and the data lines; a passivation film covering the TFT; a pixel electrode electrically connected to the TFT; a display layer formed on the pixel electrode and the passivation film, and having an electrophoretic substance; a common electrode formed on an entire surface of the display layer; an upper substrate formed on the common electrode; a seal pattern formed on each outer circumferential surface of the lower substrate, the upper substrate, and the display layer; and a dam pattern formed on the lower substrate adjacent to the seal pattern.
