| 20080287645 | Method for preparing polymer polyol stabilizer using maleic anhydride, and polymer polyol stabilizer prepared thereby - Disclosed herein is a novel stabilizer for preparing a polymer polyol, which is used to prepare polyurethane foam having improved physical properties. The stabilizer is prepared by allowing maleic anhydride to react with a polyether polyol, having an OH functionality of 3-8 and a molecular weight of 3,000-15,000, and then adding ethylene oxide to the reaction solution. Because the molecular weight and functionality of the stabilizer are increased through aging and dimerization, the stabilizer has a high molecular weight of 5,000-30,000, a high OH functionality of 6-10 and a viscosity of 3,000-15,000 cps/25° C. A polymer polyol derived from the stabilizer has low viscosity compared to those of prior products and contributes to the improvement in the physical properties of the resulting polyurethane foam. | 11-20-2008 |

| 20100022895 | DIAGNOSIS SYSTEM OF DEFICIENT AND FORCEFUL PULSE - Disclosed herein is a system for diagnosing a deficient pulse and an forceful pulse. The system includes a pulse diagnotic device, a deficient pulse and forceful pulse determining device, and an output device. The pulse diagnotic device measures pulse condition information at an examinee's Cun (˜\f˜) Gu (H), and Chi (,R) pulse-taking locations on his or her wrist using one or more pulse-taking sensors. The deficient pulse and forceful pulse determining device is operably connected to the pulse diagnotic device, analyzes the pulse pressure information measured by the pulse diagnotic device, calculates a quantified deficiency/forceful coefficient, and determines whether a pulse of interest is a deficient pulse or an forceful pulse. The output device is connected to the determining device and displays results of the determination. | 01-28-2010 |
| 20110116707 | METHOD FOR GROUPING 3D MODELS TO CLASSIFY CONSTITUTION - Provided is a three-dimensional model classification method of classifying constitutions. The method includes correcting color values of a frontal image and one or more profile images to allow a color value of a reference color table in the images to equal a predetermined reference color value, through obtaining the frontal image and one or more profile images of a subject including the reference color table by a camera, the reference color table including one or more sub color regions, generating a three-dimensional geometric model of the subject by extracting feature point information from the frontal image and the profile image, matching the corresponding feature point information to extract spatial depth information, after removing the reference color table region from the frontal image and the profile image, and classifying a group of the three-dimensional geometric model of the subject by selecting a reference three-dimensional geometric model having a smallest sum of spatial displacements from the three-dimensional geometric model of the subject from a plurality of reference three-dimensional geometric models stored in the database and setting the group which the selected reference three-dimensional geometric model represents as the group where the three-dimensional geometric model of the subject belongs. | 05-19-2011 |
| 20110142338 | METHOD OF DETECTING SKIN-COLORED AREA USING VARIABLE SKIN COLOR MODEL - The present invention relates to a method of detecting a skin-colored area using a variable skin color model. In the method, an initial skin-colored area is extracted from an input image using a skin color model, the initial skin-colored area being repeatedly extracted by adjusting a threshold value, which is a criterion for the selection of a skin-colored area, until a ratio of size of the extracted skin-colored area to size of the entire input image becomes less than a predetermined value. A skin-colored area is extracted by applying the threshold value determined in the first stage to the skin color model, the skin color model being modified by analyzing characteristics of object regions and noise regions of the skin-colored area. The skin-colored area detection method can obtain a high skin-colored object detection rate and a high false alarm rate even under various lighting and background conditions. | 06-16-2011 |

| 20080203353 | DRY-ETCHING GAS FOR SEMICONDUCTOR PROCESS - The invention is a method for continuously preparing highly pure octafluorocyclopentene for use in dry-etching processes. The method includes reacting octachlorocyclopentene with KF in a continuous manner, and purifying crude octafluorocyclopentene. In the reacting step, two KF-charged filters are installed in parallel and allowed to communicate with a reactor containing octachlorocyclopentene in an alternating manner to produce crude octafluorocyclopentene. In the purifying step, organics having lower boiling points than octafluorocyclopentene are removed, and metal ingredients and organics having boiling points higher than octafluorocyclopentene are separated to recover octafluorocyclopentene as a gas. The gaseous octafluorocyclopentene composition contains C | 08-28-2008 |
