| 20110159414 | METHOD AND SYSTEM OF FABRICATING ALTERNATING PHASE SHIFT MASK - An alternating phase shift mask is fabricated by defining transparent regions by forming light blocking patterns over a transparent substrate and forming an etch stop layer within the transparent substrate of a phase shift region among the transparent regions. The transparent substrate of the phase shift region may be etched and the etching may be deemed to be completed based upon radiation detected in an area under the etch stop layer. | 06-30-2011 |

| 20100014866 | Digital Automatic Gain Control Apparatus and Method in Burst Mode Optical Receiver - A transimpedance amplifier for a burst mode optical communication converts a burst current signal into differential output voltage signals. Using a multi-level digital AGC mechanism, the transimpedance amplifier is rapidly adapted to a burst signal whose amplitude varies in a wide range. By using an adaptive level detection method, a multi-level digital AGC can be implemented without using ADC. In addition, because the transimpedance amplifier uses a selective reset generation scheme that performs a reset operation for itself after a high power burst, a burst mode operation can be performed without external reset signals. Accordingly, the transimpedance amplifier can be integrated with an optical detector within a TO-can. Furthermore, the transimpedance amplifier can have the burst mode capability and the best sensitivity. | 01-21-2010 |
| 20100322289 | CONSTANT AMPLITUDE ENCODING APPARATUS AND METHOD FOR CODE DIVISION MULTIPLEXING COMMUNICATION SYSTEM - Disclosed are an apparatus and method for constant amplitude encoding of a transmission signal in a CDM (Code Division Multiplexing) communication system. The apparatus for constant amplitude encoding of a transmission signal includes: an encoding module sequentially performing horizontal encoding and vertical encoding on an input signal; and a spreading and multiplexing module spreading the signal which has been encoded by the encoding module and multiplexing the spread signal in a vertical direction to output a data stream having a constant amplitude. | 12-23-2010 |
| 20110148349 | APPARATUS AND METHOD FOR CHARGING INTERNAL BATTERY IN WIRELESS SENSOR NETWORK - Provided are an apparatus and method for charging an internal battery in a wireless sensor network. A method for a slave sensor node to charge an internal battery in a sensor network includes estimating an hourly chargeable electric energy rate in a scan phase with a master sensor node, transmitting the estimated hourly chargeable electric energy rate using an association request message requesting association with the master sensor node after recognizing the master sensor node, requesting charging from the master sensor node and performing wireless charging when a power level of an internal battery requires charging, reporting the power level of the internal battery varied by the wireless charging to the master sensor node by predetermined time periods during the wireless charging, and stopping the wireless charging when the power level reported to the master sensor node reaches a predetermined power level. | 06-23-2011 |

| 20090244111 | DISPLAY DEVICE AND DRIVING APPARATUS AND METHOD THEREOF - A data processor receives sets of input image data having respective input grays and outputs sets of output image data having respective output grays. Each set of output image data corresponds to one of the plurality of sets of input image data and have more image data than each set of the input image data. A data driver supplies the pixels with data voltages corresponding to the output image data supplied from the data processor. A set of output grays corresponding to a set of input grays are selected from sets of grays, each set of grays giving an average front transmittance substantially equal to an average front transmittance of the set of input grays. The sets of output grays generate the closest average lateral gamma curve generated by the sets of grays relative to an average front gamma curve generated by the input grays. | 10-01-2009 |
