| 20090169175 | APPARATUS AND METHOD FOR DISPLAY RECORDING - A method for displaying a record in an initial driving state of a record displaying apparatus is disclosed. The method includes searching execution/non-execution file descriptors of recorded multimedia files, and extracting record files not played back, and outputting a record file alarming message when a record file not played back is extracted. The record displaying apparatus is also disclosed. Execution/non-execution file descriptors of record files are searched upon system initialization of a broadcast receiver. When there is a new record or a record not played back, a record file alarming message is output in a state of being overlaid on a broadcast signal received. Accordingly, the user can access the record file list simultaneously with viewing a broadcast, without using any additional means. | 07-02-2009 |

| 20090112384 | Startup sequence control method of fuel cell-super capacitor hybrid electric vehicle - The present invention provides a startup sequence control method of fuel cell-super capacitor hybrid electric vehicles, which can protect a fuel cell at the time of the starting of the fuel cell, reduce the start-up time and promote convenience of a driver in a fuel cell-super capacitor serial hybrid system which does not employ a high-voltage power converter. The startup sequence control method comprises the steps of: determining whether or not a low-voltage auxiliary battery is in a state where its voltage is less than a reference voltage or in a cold start condition after a key-on signal has been input; if the auxiliary battery is in the state where its voltage is less than a reference voltage or in the cold start condition, matching the voltage of a main bus terminal to the voltage of an auxiliary power source through the voltage boost of a power converter; turning on a relay for cutting off the voltage of the auxiliary power source and a main relay of a precharge unit for the auxiliary power source; and turning off the power converter and then driving a fuel cell auxiliary component using the auxiliary power source to thereby boost a fuel cell voltage. | 04-30-2009 |
| 20110025241 | SENSORLESS CONTROL METHOD OF HIGH PERFORMANCE PERMANENT MAGNET SYNCHRONOUS MOTOR DURING EMERGENCY OPERATION - The present invention provides a position sensorless control method of a high performance permanent magnet synchronous motor during emergency operation, which can accurately detect a magnetic pole position of the synchronous motor based on a position sensorless vector control using an adaptive observer configured based on a permanent magnet synchronous motor model. | 02-03-2011 |
| 20110029172 | APPARATUS AND METHOD FOR CONTROLLING MOTOR POSITION AND CREEP OF ELECTRIC VEHICLE - The present invention provides an apparatus and method for controlling motor position and creep of an electric vehicle, in which when a running vehicle is stopped, motor position control for maintaining the vehicle in the stopped position even when a brake pedal is released is performed, and then creep torque control is performed such that the vehicle is prevented from rolling backwards and suddenly starting when the vehicle is restarted after a stop on a slope. | 02-03-2011 |

| 20120122275 | METHODS OF FABRICATING ORGANIC THIN FILM TRANSISTORS - Disclosed is a method for forming banks during the fabrication of electronic devices incorporating an organic semiconductor material that includes preparing an aqueous coating composition having at least a water-soluble polymer, a UV curing agent and a water-soluble fluorine compound. This coating composition is applied to a substrate, exposed using UV radiation and then developed using an aqueous developing composition to form the bank pattern. Because the coating composition can be developed using an aqueous composition rather than an organic solvent or solvent system, the method tends to preserve the integrity of other organic structures present on the substrate. Further, the incorporation of the fluorine compound in the aqueous solution provides a degree of control over the contact angles exhibited on the surface of the bank pattern and thereby can avoid or reduce subsequent surface treatments. | 05-17-2012 |
