Hyun-Il Kim, Busan KR

Patent application number	Description	Published
20120095067	PHARMACEUTICAL COMPOSITION CONTAINING CARBOXYLOSARTAN AND A PRODUCTION METHOD THEREFOR - Disclosed is a pharmaceutical composition containing losartan carboxylic acid and a preparing method thereof. The pharmaceutical composition has the improved dissolution speed and dissolution rate, and the reduced variation in dissolution depending on the pH of a medium.	04-19-2012

Hyun-Il Lee, Gwangjin-Gu KR

Patent application number	Description	Published
20090205156	CLEANER APPARATUS - A vacuum apparatus having a suction nozzle, an air suction unit to which the suction nozzle is pivotally connected and which fluidly communicates with the suction nozzle through a connection channel, a dirt receptacle which has at least two collecting parts fluidly communicating with at least two outlets formed at the air suction unit, respectively.	08-20-2009

Hyun-Il Park, Hwaseong-Si KR

Patent application number	Description	Published
20090096383	Inverter and Liquid Crystal Display Device Including the Same - Disclosed is a liquid crystal display panel which includes a switching circuit for converting an input voltage into an alternating current (AC) voltage, a transformer for boosting the AC voltage generated from the switching circuit, and a bypass capacitor part connected in parallel between an output terminal of the switching circuit and the transformer.	04-16-2009
20090284499	CONTROLLER BOARD, DISPLAY DEVICE HAVING THE SAME AND METHOD OF CONTROLLING THE DISPLAY DEVICE - A controller board includes a memory and a timing controller. The memory stores previous frame image data. The timing controller outputs driving image data based on current frame image data supplied from an external device and the previous frame image data. The timing controller disperses a frequency band of the current frame image data within a reference frequency range to generate dispersed current frame image data and transmits the dispersed current frame image data to the memory.	11-19-2009

Hyun-Il Yoo, Seoul KR

Patent application number	Description	Published
20090156214	Preamble design method for reducing overhead during handover in hierarchical cellular system - Provided is a handover method of a wireless communication system using a hierarchical cellular scheme. In the method, signal quality of a serving node is measured, so that whether to start scanning for a handover is determined. When the scanning for the handover starts, signal qualities of a serving cell including the serving node and one or more neighbor cells are measured through a first preamble including a first identifier for distinguishing a cell. An intra-cell handover or an inter-cell handover is selected using the signal qualities of the serving cell and the neighbor cells. Therefore, a terminal can easily distinguish between the inter-cell handover and the intra-cell handover, and an overhead during a handover can be reduced because an intra-cell handover procedure is simplified.	06-18-2009
20110280176	A DEVICE AND METHOD FOR TRANSMITTING RELAY SYNCHRONIZATION SIGNAL ON LTE-A SYSTEM BASED ON ORTHOGONAL FREQUENCY DIVISION HAVING A MULTI-HOP RELAY - Provided is a relay-synchronization signal (R-SS) transmitting apparatus and method in an orthogonal frequency division multiplexing (OFDM)-based Long Term Evolution Advanced (LTE-A) system having a multi-hop relay. The R-SS transmitting apparatus generates a R-SS having the same peak-to-average power ratio (PAPR) characteristic as a synchronization signal (SS) and having a lower correlation characteristic than the SS, using the SS for synchronization with a terminal, for synchronization between a relay and a base station, for a synchronization between a relay and a subordinate relay, and for monitoring, by a relay, an adjacent base station or an adjacent relay	11-17-2011
