| 20100177313 | INSPECTING METHOD USING AN ELECTRO OPTICAL DETECTOR - An inspecting method using an electro-optical detecting device is disclosed. The electro-optical detecting device includes: an upper substrate and a lower substrate; a nematic liquid crystal layer interposed between the upper substrate and the lower substrate; a transparent electrode interposed between the nematic liquid crystal layer and the upper substrate, the transparent electrode connected to a device under test (DUT) via a power supply; a polarizing plate located over the nematic liquid crystal layer; and a reflecting plate located under the nematic liquid crystal layer. A method using the electro-optical detecting device includes applying a voltage between the transparent electrode and the DUT to generate an electric field across the liquid crystal layer; illuminating the detector and capturing an image of the detector using the light reflected from the detector; and determining the DUT has some defects from the image of the detector by an abnormal electric field generated between the transparent electrode and the DUT. | 07-15-2010 |

| 20110178594 | BIOABSORBABLE BLEND FOR TEMPORARY SCAFFOLDING OF THE BLOOD VESSEL WALL - A bioabsorbable blend comprising poly(L-lactide) (PLLA) and a phosphorylcholine group-containing copolymer (PPCP) capable of enduring the mechanical strength of blood vessel walls and applicable for fabricating cardiovascular devices was developed. The blend acts as a scaffold to support blood vessel walls during vascular healing and undergoes biodegradation in vivo after vascular healing is complete. Furthermore, the blend can prevent the formation and adsorption of thrombi. | 07-21-2011 |

| 20100115552 | Method and apparatus for receiving electronic service guide by mobile communication terminal in digital video broadcasting-handheld system - A method and apparatus is provided for receiving an Electronic Service Guide (ESG) by a mobile communication terminal in a Digital Video Broadcasting-Handheld (DVB-H) system including a service provider providing a broadcast service and the mobile communication terminal receiving the broadcast service from the service provider. Upon receipt of a broadcast service request, the mobile communication terminal determines whether a first ESG about the broadcast service has been stored. When the first ESG has been stored, the mobile communication terminal requests the service provider to first transmit broadcast data among a second ESG and the broadcast data contained in the broadcast service, based on the first ESG. The mobile communication terminal receives the broadcast data first from the service provider and displays the received broadcast data. | 05-06-2010 |
