| 20100046662 | DIGITAL CLIPPING METHOD FOR A TRANSMITTER OF AN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM - The present invention relates to a digital clipping method for reducing a high peak-to-average power ratio (PAPR) of a transmission signal in a transmitter of an orthogonal frequency division multiplexing access (OFDMA) system. In the method, a) the transmission signal to be digitally clipped is divided into real and imaginary parts, b) magnitudes of the real and imaginary part signals are divided into a plurality clipping levels, and c) the transmission signal is respectively clipped by comparing the real and imaginary part signals with the plurality of clipping levels while allowing phase errors. In c), a plurality of comparators is used to respectively compare the real and imaginary parts of the complex number transmission signal with the plurality of clipping levels. | 02-25-2010 |

| 20090315980 | IMAGE PROCESSING METHOD AND APPARATUS - An image processing method including outputting a predetermined region of one or more frames of video data as a two-dimensional (2D) image and other regions of the one or more frames as a three-dimensional (3D) image by using meta data of the video data, where the meta data includes information to classify the frames into predetermined units. | 12-24-2009 |
| 20090269030 | STORAGE MEDIUM INCLUDING AV DATA AND APPLICATION PROGRAM, AND APPARATUS AND METHOD USING THE SAME - A storage medium including audio-video (AV) data and application programs for providing additional functions using the AV data includes: movie mode data for reproducing audio-visual (AV) data; program mode data including a plurality of application programs for providing additional functions using the AV data; system data for controlling the execution of the movie mode data and the program mode data; and management information for managing the execution of the application programs in a unit of title, wherein the system data comprises mode information indicating whether a reproduction mode of a title to be reproduced is a movie mode or a program mode. | 10-29-2009 |
| 20090195937 | Actuator latch apparatus for disk drive - An actuator latch apparatus for a disk drive, having a notch positioned at a first end portion of the swing arm, a latch lever rotatably installed in a base member, a first core provided on a second end portion of the swing arm, and a second core provided at a counterbalance of the latch lever. The first and second cores apply a torque to the swing arm and latch lever, respectively, in a first direction by a magnetic force of the magnet. The latch lever has a latch pivot, a latch arm provided at a first side of the latch pivot and having a hook to be caught by the notch when the actuator is locked, and the counterbalance provided on a second side of the latch pivot. The latch arm of the latch lever is elastically deformed when contacted by the swing arm during parking of the head. | 08-06-2009 |
| 20090129249 | INFORMATION STORAGE MEDIUM AND METHOD OF RECORDING AND/OR REPRODUCING WITH RESPECT TO THE MEDIUM - An information storage medium includes an area in which updated disc-related information and recording-related information updated with a change in at least one of a disc version number and a recording speed is recorded along with existing disc-related information and recording-related information. The existing disc-related information and recording-related information are recorded, and the updated disc-related information and recording-related information is recorded in an area in which the existing disc-related information and recording-related information is recorded. Accordingly, data can be recorded/reproduced on/from a new version of information storage medium even using an existing drive. | 05-21-2009 |
| 20080320311 | APPARATUS AND METHOD FOR AUTHENTICATING FIRMWARE - An apparatus and method to authenticate firmware stored in a firmware storage unit. The apparatus includes a controller to commands an authenticator to start firmware authentication, the authenticator, which performs authentication of the firmware using a signature read from the firmware storage unit, and a bus controller to controls a data transmission bus to a decoder. The authenticator prevents data from being transmitted through the data transmission bus if the firmware authentication fails, and the authenticator controls the bus controller to enable data to be transmitted through the data transmission bus if the firmware authentication succeeds. Using the apparatus, illegal use of content can be prevented. | 12-25-2008 |
| 20080315858 | SWITCH MODE POWER SUPPLY APPARATUS HAVING ACTIVE CLAMPING CIRCUIT - A switch mode power supply apparatus includes a transformer, a main switching device to adjust a power supply supplied to a primary coil of the transformer, an active clamping circuit to suppress a voltage stress of the main switching device, and a control circuit to control a clamping operation of the active clamping circuit when the switch mode power supply apparatus is in a standby mode. Therewith, it is possible to significantly reduce power consumption of the switch mode power supply apparatus in the standby mode and improve efficiency of the switch mode power supply apparatus. | 12-25-2008 |
| 20080258554 | POWER CONDITIONER AND METHOD OF MANAGING THE SAME - A power conditioner includes a main converter to transform a voltage outputted from a power source into a first transformed voltage and output the first transformed voltage to supply power to a power using point; and an auxiliary converter to transform the first transformed voltage outputted from the main converter into a second transformed voltage and output the second transformed voltage to supply power to balance-of-plant (BOP) elements including driving devices of the power source.
