摘要： 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.

摘要： There is provided a drill bit capable of performing a continuous drilling operation on a high-strength workpiece such as a tempered tile and the like. The drill bit comprises a bit body having a receptor portion formed therein, the receptor portion being filled with a cutting oil; a drilling portion extended from one end of the bit body and coupled to the receptor portion of the bit body to form a channel in which a capillary phenomenon occurs, and having an opening formed in one end thereof; and a cutting portion provided in the opening of the drilling portion to drill a workpiece. The drill bit thus configured may be useful to enable a continuous drilling operation on the high-strength workpiece, to enable the refilling of a cutting oil used to cool the high-strength workpiece, to shorten a time for the drilling operation on the high-strength workpiece, and to drill the high-strength work-piece to the maximum extent using the minimum number of drill bits.
