| 20110149041 | APPARATUS AND METHOD FOR CAMERA PARAMETER CALIBRATION - The present invention provides an apparatus and method for camera parameter calibration which is capable of easily and simply setting physical and optical characteristic parameters of a camera in order to acquire information on actual measurement of an image provided through the camera with high accuracy. The camera parameter calibration apparatus and method has an advantage of correct image analysis that it is capable of increasing accuracy of information of measurement through an image only with an intuitive interface manipulation, without taking a time-consuming and incorrect actual measurement procedure, by determining parameters of the space model corresponding to the image by displaying a 3D space model corresponding to a real space of the image on the image and changing and adjusting visual point parameters such that the 3D space model matches the display image, and regarding the determined parameters of the space model as camera parameters of the image. | 06-23-2011 |

| 20090132784 | CACHE MEMORY AND METHOD OF OPERATING THE SAME - Provided are a cache memory using a linear hash function and a method of operating the same. The cache memory includes: a first hash function module for converting a main memory address received from a central processing unit (CPU) into a first index value using a first hash function; a second hash function module for converting the main memory address into a second index value using a second hash function; a first comparator for comparing a tag value of a data block located at the first index value in the first bank with a tag value of the main memory address; and a second comparator for comparing a tag value of a data block located at the second index value in the second bank with the tag value of the main memory address. In a pair of linear hash functions according to the present invention, each constructed with a 2m×m binary matrix, even if m is an odd number, each of the linear hash functions has the highest degree of interbank dispersion and avoids conflicts in row, column, diagonal, anti-diagonal, and rectangular patterns, so that a 2-way skewed associative cache can be constructed in relatively wide ranges. | 05-21-2009 |

| 20080308131 | Method and apparatus for cleaning and driving wafers - The present invention is directed to a method and an apparatus for cleaning and drying wafers. The apparatus includes an injection unit having first and second injection ports configured for injecting different fluids and arranged in a moving direction of the rose or on a line adjacent to the moving direction. The injection unit migrates straightly from the center of a wafer to the edge thereof, and the first and second injection ports are linearly arranged on a moving line of the nozzle. | 12-18-2008 |
| 20100123274 | METHOD FOR SYNTHESIZING CONDUCTIVE COMPOSITE - Provided are an apparatus and method for synthesizing a conductive composite with enhanced electrical conductivity. The apparatus includes: an injection-molding machine which injection-molds pellets created by mixing carbon nanotubes (CNTs) with polymers; and an electric field generator which applies an electric field to the pellets that are melted while the melted pellets are injection-molded and thus rearranges the CNTs included in a composite into which the melted pellets are injection-molded. | 05-20-2010 |
| 20100278713 | Method of manufacturing a carbon nanotube, and apparatus and system for performing the method - In a method of manufacturing a carbon nanotube, a boat configured to receive substrates is positioned outside of a synthesis space where the carbon nanotube is synthesized. The substrates are loaded into the boat. The boat is then transferred to the synthesis space. A process for forming the carbon nanotube is performed on the substrates in the synthesis space to form the carbon nanotube. Thus, the carbon nanotube may be effectively manufactured. | 11-04-2010 |
| 20100284897 | Apparatus and method for synthesizing carbon nanotube - An apparatus for synthesizing a carbon nanotube includes a reaction chamber, a cassette, a transferring member, a heater, a gas supply member and a gas exhausting part. The carbon nanotube is synthesized in the reaction chamber. The reaction chamber has a substantially vertical major axis. The cassette holds a plurality of substrates. The transferring member transfers the cassette along a direction substantially in parallel relative to the major axis to load/unload the cassette into/from the reaction chamber. The heater heats the reaction chamber. The gas supply member provides the reaction chamber with a gas for synthesizing the carbon nanotube. The gas exhausting member exhausts a remaining gas from the reaction chamber. Collecting the carbon nanotube may be facilitated and managing the reaction chamber may be effective to enhance a productivity of the carbon nanotube. | 11-11-2010 |
