| 20080201368 | Method and System for Registering and Retrieving Production Information - In particular embodiments, an online trading system receives a product registration request including product description from a user terminal. Then, image information is extracted from the product description and a resource locator of the image information is generated. Then, an image list is generated based on the product description and the resource locator of the image information. The image list is sent to a search service DB server, where the image list is associated with a keyword relevant to the product description. Further, the image list may be sent to a UCC DB server. In this case, the UCC DB server generates a UCC containing the image list and sends a resource locator of the UCC to the search service DB server, which associates the resource locator of the UCC with a keyword relevant to the product description. If the search service server receives a search query including a keyword from a user terminal, the search service server searches a search service database to retrieve an image list or a resource locator of UCC containing an image list relevant to the keyword. | 08-21-2008 |

| 20090160490 | REFERENCE VOLTAGE GENERATOR OF ANALOG-TO-DIGITAL CONVERTER - A reference voltage generator, which is used in an analog-to-digital converter, minimizes influence of kickback noise by dividing a full scale reference voltage into a number of reference voltages using a ladder resistor unit, and applying the number of reference voltages to a number of comparators, and matches a reference common mode voltage to an input common mode voltage by forming a common feedback loop using another ladder resistor unit which is a replica of the ladder resistor unit. Therefore, since kickback noise is locally discharged by a decoupling capacitor connected to each ladder resistor and a peak value of the kickback noise is also reduced, it is possible to optimize the ladder resistor unit according to power consumption. Also, since the common feedback loop is formed as a replica of the ladder resistor unit, it is possible to match a reference common mode signal to an input common mode signal. | 06-25-2009 |
