| 20090167966 | See-through display apparatus and method thereof - A see-through display apparatus and a method thereof are provided. The see-through display apparatus includes: a screen which changes its transparency by varying its light scattering properties; a projector which projects an image onto the screen; and a control unit which controls a change of transparency of the screen. Accordingly, an image can be clearly displayed on the screen by controlling light scattering and non-scattering states of the screen, and also a user can monitor the external environment through the screen. | 07-02-2009 |

| 20080252558 | COLOR DISPLAY APPARATUS - Disclosed herein is a color display apparatus which has a pixel pattern including a plurality of repeating units of a pixel array, wherein each of the plurality of repeating units of the pixel array is composed of at least five sub-pixels while including at least one sub-pixel from a first to fourth sub-pixel, respectively, the first sub-pixel representing a red color (R), the second sub-pixel representing a green color (G), the third sub-pixel representing a blue color (B), and the fourth sub-pixel representing a mixed color of at least two colors from among the R, G, and B, and each of the plurality of repeating units of the pixel array corresponds to at least two image pixels. | 10-16-2008 |
| 20080259192 | Apparatus and method for capturing images - Provided are an apparatus and a method for capturing images by applying different color filters to two pixel regions with IR blocking filters removed so that optical signals in the visible band and IR signals can be received. The apparatus includes a filter unit having a plurality of filters having different wavelength bands; a sensor unit sensing optical signals passing through the filters; and a signal-extraction unit extracting detailed optical signals in respective wavelength bands by using the difference between the sensed optical signals. | 10-23-2008 |

| 20110032864 | METHODS OF PERFORMING COOPERATIVE COMMUNICATION IN WIRELESS LANs - Method of performing cooperative communication in wireless LAN includes determining, by receiver, whether cooperative communication is necessary based on transmission request signal provided from transmitter, when it is determined that the cooperative communication is necessary, transmitting, by the receiver, transmission response signal instructing the cooperative communication, overhearing, by a plurality of devices, the transmission response signal instructing the cooperative communication, transmitting, by at least one of the devices, response signal for supporting relaying to the transmitter, selecting, by the transmitter, a relay based on the response signal, transmitting, by the transmitter, data to the relay, and attaching, by the relay, data of the relay to the data transmitted by the transmitter and transmitting result data to the receiver. Thus, average transmission rate of wireless LAN can be improved with minimized overhead, and additional transmission opportunity can be provided to relaying device, thereby properly rewarding relaying device. | 02-10-2011 |
