| 20080284623 | LOSSLESS AUDIO CODING/DECODING APPARATUS AND METHOD - Provided are a lossless audio coding/decoding apparatus and method. The lossless audio coding apparatus includes a first coder to directly code first symbols; a second coder module comprising a plurality of second coders to convert the first symbols into second symbols and to code the second symbols; a first selector to compare the performance of the first coder to the performance of the second coders and to output a coding mode in accordance with a comparison result; and a second selector to output a final bitstream by coding the first symbols in correspondence with the coding mode. According to the present invention, the performance of audio coding may be improved. | 11-20-2008 |

| 20090200462 | SCANNING PROBE MICROSCOPE CAPABLE OF MEASURING SAMPLES HAVING OVERHANG STRUCTURE - A scanning probe microscope tilts the scanning direction of a z-scanner by a precise amount and with high repeatability using a movable assembly that rotates the scanning direction of the z-scanner with respect to the sample plane. The movable assembly is moved along a curved guide and has grooves that engage with corresponding projections on a stationary frame to precisely position the movable assembly at predefined locations along the curved guide. | 08-13-2009 |
| 20100037360 | SCANNING PROBE MICROSCOPE WITH AUTOMATIC PROBE REPLACEMENT FUNCTION - An automatic probe exchange system for a scanning probe microscope (SPM) exchanges probes between a probe mount on the SPM and a probe mount on a probe tray based on differential magnetic force. When the magnetic force on the SPM side is greater, the probe is attached to the probe mount on the SPM. When the magnetic force on the probe tray side is greater, the probe is attached to the probe mount on the probe tray. The magnetic force on the probe tray side is varied by moving the magnets that generate the magnetic force on the probe tray side closer to or further from the probe. | 02-11-2010 |
| 20100170015 | SCANNING PROBE MICROSCOPE CAPABLE OF MEASURING SAMPLES HAVING OVERHANG STRUCTURE - A scanning probe microscope tilts the scanning direction of a z-scanner by a precise amount and with high repeatability using a movable assembly that rotates the scanning direction of the z-scanner with respect to the sample plane. The movable assembly is moved along a curved guide by a rack-and-pinion drive system and has grooves that engage with corresponding ceramic balls formed on a stationary frame to precisely position the movable assembly at predefined locations along the curved guide. The grooves are urged against the ceramic balls via a spring force and, prior to movement of the movable assembly, a pneumatic force is applied to overcome the spring force and disengage the grooves from the ceramic balls. | 07-01-2010 |

| 20100017920 | SCANNING PROBE MICROSCOPE WITH TILTED SAMPLE STAGE - A scanning probe microscope has a tilting stage on which a sample is mounted. The sample is scanned back and forth with the stage being tilted clockwise during a forward scan and counterclockwise during a reverse scan. A first surface contour of the sample is determined from the response of the probe and the tilt angle of the stage during the forward scan. A second surface contour of the sample is determined from the response of the probe and the tilt angle of the stage during the reverse scan. A final surface contour of the sample is obtained by combining the first and second surface contours. | 01-21-2010 |

| 20090067812 | Methods of playing/recording moving picture using caption search and image processing apparatuses employing the method - Provided are image processing methods and apparatuses for playing/recording a moving picture using caption search, which are capable of easily playing and recording the moving picture from a desired location by searching through captions of the moving picture. The method searches for a caption corresponding to a search key word among captions of the moving picture based on the search key word, displays a search-result list, and records at least one item included in the displayed search-result list according to a selected recording mode. Accordingly, a desired location of the moving picture can be played and/or recorded through caption search. Because the moving picture can be played from a predetermined location using caption search and a user's voice can be recorded and output, efficient foreign-language learning may be possible. | 03-12-2009 |
