20100201251 | FIELD EMISSION DISPLAY AND MANUFACTURING METHOD OF THE SAME HAVING SELECTIVE ARRAY OF ELECTRON EMISSION SOURCE - The present invention relates to a field emission display and a manufacturing method of the same having selective positioning of electron field emitters. More specifically, the present invention provides a field emission display and a manufacturing method of the same having selective positioning of electron field emitters which can prevent a cross-talk that is a mutual interference phenomenon between pixels and improve uniformity of pixels based on uniform electron emission by deciding positions of carbon nano-tubes which are sources of electron emission and growing carbon nano-tubes before the structure of electrodes is formed, and forming spacers directly on electrodes such that the spacers divide carbon nano-tubes formed uniformly and selectively into pixel units. | 08-12-2010 |
20100115363 | COOPERATIVE H-ARQ SUPPORTING METHOD - In the hybrid automatic repeat request (H-ARQ) supporting method for cooperative transmission, a receiver selects one H-ARQ repeat method from among the chase combining method and the incremental redundancy method according to the SNR when the data packet cooperatively transmitted by transmitters generates an error. Also, the method for the receiver to select a repeat transmitter includes a method for selecting a repeat transmitter in advance, a method for removing a transmitting node from a repeat transmitter group when the SNR of the transmitting node is low, and a method for estimating the SNR of each transmitter for each predetermined time frame and selecting the transmitter having the greatest SNR as the repeat transmitter. | 05-06-2010 |
20100028244 | FULLERENE MANIFOLD AND MANUFACTURING METHOD OF THE SAME HAVING CHARACTERISTIC OF WHITE PHOTOEMISSION - A fullerene manifold with a size of several to tens of nanometers, having a characteristic of white photoemission of a closed shell structure, the fullerene manifold being formed by dissolving a substance of fullerene monomers such as C | 02-04-2010 |
20080298335 | Multi-Carrier Cdma Transmitting Device and Method Using Block-Based Multi-Carrier Spreading - A multi-carrier CDMA transfer device using block-based partial-carrier spreading uses block-based partial-carrier spreading in the multi-cell environment to be applied to MC-CDMA models (FH-MC/CDMA TDD) that are strong against multi-path fading. A transmitter of the transfer device spreads carriers per block in the frequency domain by using the block-based partial-carrier spreading, and a receiver despreads received signals by using the block-based partial-carrier and restore original data. Optionally, an array antenna having a plurality of antenna elements is applied to the transmitter and the receiver, and weights are adaptively applied depending on the channel quality when transmitting and receiving signals through the antenna elements. Therefore, frequency diversity is obtainable and inter-cell interference and inter-code interference is optimized in the MC-CDMA method. Also, changes of frequency hopping reduce temporal variations of channels and prevent a high SN ratio. | 12-04-2008 |
20080233975 | Paging method and apparatus for heterogeneous wireless network system - In a heterogeneous wireless network system, a apparatus for notifying a mobile station of existence of traffic from a network to which the mobile station is not connected receives an identifier of the mobile station from the network to which the mobile station is not connected. The apparatus checks the network to which the mobile station having the same identifier as the received is connected, and transmits a signal for indicating existence of traffic to the mobile station by using the network's interface. | 09-25-2008 |
20080233216 | Composition Comprising the Extract of Siegesbeckiae Herba For Preventing and Treating Arthritis and the Use Thereof - The extract of Siegesbeckiae herba of the present invention showed potent inhibitory effect on the dissociation of proteoglycan and type II collagen in chondrocyte and cartilage tissue and protecting effect on cartilage due to the inhibition of MMP-1, MMP-3 and MMP-13 activity and the restoring effect on cartilage tissue, the anti-inflammatory and antiphlogistic effect in edema animal model, anti-inflammatory effect confirmed by the inhibition test on PGE | 09-25-2008 |
20080232280 | Registration method of multiple care-of address - The present invention relates to a binding update identifier sub-option field configuration method and a binding update information configuration method. In the method, a binding update identifier sub-option field including current used interface and data characteristics and corresponding to one interface of the plurality of interfaces is generated, the binding update identifier sub-option field is transmitted to a home agent and a correspondent node, a care-of address corresponding to a binding update identifier is stored, and binding update is performed. | 09-25-2008 |
