| 20090267973 | ORGANIC LIGHT EMITTING DISPLAY DEVICE AND DRIVING METHOD FOR THE SAME - An organic light emitting display device is provided. The device includes a photo sensor adapted to: sense a brightness of ambient light; output a pulse width of an emission control signal corresponding to a sensed brightness of the ambient light; and output a gamma compensation coefficient corresponding to the sensed brightness of the ambient light and a user selected brightness. The device also includes a gamma compensation circuit adapted to adjust a magnitude of a voltage between a plurality of gradation voltages according to the output gamma compensation coefficient. The device also includes a scan driver and a data driver. The device also includes a pixel portion including a pixel adapted to: emit light according to the data signal, the scan signal, and the emission control signal; and display an image corresponding to the user selected brightness. | 10-29-2009 |
| 20100146364 | METHOD AND APPARATUS FOR ENCODING/DECODING BUS SIGNAL - Provided is a bus signal encoding/decoding method and apparatus. The bus signal encoding method includes receiving a bus signal, XOR-operating all but the first byte sequence of the bus signal in a bitwise manner, inverting the even-numbered byte sequences of the XOR-operated bus signal in a bitwise manner, and serializing the inverted bus signal. | 06-10-2010 |
| 20100161861 | BUS DATA TRANSMISSION APPARATUS, METHOD FOR TRANSMITTING BUS DATA AND BUS DATA COMMUNICATION APPARATUS - Provided are a method and an apparatus for compression transmission of bus data including a plurality of bytes including upper bits and lower bits. The apparatus includes a comparator and an aligner. The comparator compares upper bits of a previous byte with upper bits of a current byte among the plurality of bytes. If the upper bits of the previous byte are identical to the upper bits of the current byte, the aligner compresses the bus data in a combination of a full-byte and a half-byte, by allowing the previous byte to be constituted with the full-byte having bits corresponding to the number of bits of the previous byte and allowing the current byte to be constituted with the half-byte excluding the upper bits of the current byte. Then, the aligner arrays the compressed bus data in a preset bus bandwidth to transmit to a slave device. | 06-24-2010 |
| 20100270463 | APPARATUS AND METHOD FOR MEASURING DEPTH-OF-INTERACTION USING LIGHT DISPERSION AND POSITRON EMISSION TOMOGRAPHY USING THE SAME - The present invention provides an apparatus for measuring a Depth-Of-Interaction (DOI), comprising a crystal layer | 10-28-2010 |
| 20110075539 | RECORDING MEDIUM RECORDING/REPRODUCING METHOD AND A RECORDING MEDIUM RECORDING/REPRODUCING APPARATUS - The present invention provides a recording medium reproducing method comprising the steps of: irradiating light onto a recording medium, the recording medium including a data image and a reference pattern, the reference pattern being divided by a plurality of fractional regions, the fractional regions being in invert, rotational and symmetrical relationship; determining information associated to data-image distortion based on the reference pattern; and correcting position of the data image based on the information relating to data-image distortion. | 03-31-2011 |
| 20110138481 | RECORDING MEDIUM, AND RECORDING/REPRODUCING METHOD AND RECORDING/REPRODUCING APPARATUS FOR RECORDING MEDIUM - The present invention provides a recording/reproducing method for a recording medium including a data recording layer and a user information recording layer, wherein the recording/reproducing method includes the steps of: receiving inputted user information; determining whether the inputted user information matches the user information recorded on the user information recording layer of the recording medium; and recording data onto the data recording layer of the recording medium, or reproducing data of the data recording layer, in accordance with the result of the determination. | 06-09-2011 |
| 20110192980 | SYSTEM AND METHOD FOR COMPENSATING FOR ANODE GAIN NON-UNIFORMITY IN MULTI-ANODE POSITION SENSITIVE PHOTOMULTIPLIER TUBE - The present invention relates to a system and method for compensating for anode gain non-uniformity in a Multi-anode Position Sensitive Photomultiplier Tube (PS-PMT), in which a compensation unit is disposed between the multi-anode position sensitive photomultiplier tube and a position detection circuit unit and configured to uniform a current signal inputted to the position detection circuit unit, thereby compensating for anode gain non-uniformity. In accordance with the present invention, the compensation unit for changing resistance is used. Accordingly, there is an advantage in that the gain non-uniformity of each of the anodes of the PS-PMT can be compensated for. Furthermore, the gain non-uniformity of each of the anodes of the PS-PMT is compensated for by changing resistance values of the variable resistances of the compensation unit. Accordingly, there is an advantage in that the interaction positions of gamma rays can be calculated more precisely. | 08-11-2011 |
