| 20090168183 | OPTICAL MEMBER AND DISPLAY HAVING THE SAME - The present invention relates to an optical member for controlling light refraction and a display. An optical member of the present invention includes a base material and a foaming portion having a large number of foam elements. According to the present invention, a reflection or diffusion sheet can be manufactured by controlling the size of foam elements in the optical member. In addition, there is provided an optical member, which is formed of a foaming resin, which has no light diffusing agent in a base material layer and does not require a conventional stretching process, thereby securing light scattering power. | 07-02-2009 |

| 20100111314 | APPARATUS AND METHOD FOR LOCALIZING SOUND SOURCE IN REAL TIME - 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. | 05-06-2010 |
