Abstract:
An electron emission device, and an electron emission display using the electron emission device, includes a substrate, electron emission regions formed on the substrate, driving electrodes formed on the substrate to control electron emissions of the electron emission regions, and a focusing electrode disposed above the driving electrodes and insulated from the driving electrodes, the focusing electrode having openings through which electron beams pass. The focusing electrode includes at least two focusing parts electrically separated from each other and the focusing parts focus the electron beams in different directions.
Abstract:
An electron emission device includes first and second substrates facing each other while a vacuum space is interposed therebetween. An electron emission array is formed on the first substrate to emit electrons toward the second substrate, and phosphor layers are formed on the second substrate. An anode electrode is formed on a surface of the phosphor layers, and receives the voltage required for accelerating electron beams from the electron emission array. A grid electrode is disposed between the first and second substrates and is closer to the second substrate than to the first substrate. The grid electrode has electron beam passage holes, and receives a voltage lower than a location reference voltage.
Abstract:
A data encryption method for an IEEE 1394 serial bus network, a data encryption method for an IEEE 1394 serial bus network, comprising the steps of requesting a private encryption at a data transmission node using a predetermined encryption algorithm at a data receiving node; recognizing and confirming that the data transmission node set the private encryption requesting at the data receiving node; transmitting an encrypted data at the data transmission node when the receiving node requests a service at the data transmission node; and decoding the encrypted data using a predetermined unencrypting key at the data receiving node, for thereby transmitting an encryption algorithm and encryption data to a corresponding node when a service is requested from a receiving node with respect to a certain system by setting an encryption algorithm in the system and decoding an encrypted data transmitted from the system in accordance with an encryption algorithm and displaying the same, so that a certain user can use a service.

Disclosed herein is a composition comprising a regioregular polyalkylthiophene and/or a regioregular poly[2,5-bis(3-alkylthiophen-2-yl)thieno(3,2-b)thiophene]; where the composition is melted and then cooled to a temperature between a melting point and a glass transition temperature of the composition; the composition having an amount of crystallinity that is at least twice the amount of crystallinity of another identical composition that is crystallized by a method that does not involve melting and cooling to a temperature between the melting point and the glass transition temperature of the identical composition.
Abstract:
A leg stretching apparatus can be safely used without a risk of damage, with a simple coupling and can be conveniently installed at a site at which leg stretching is desired to enable efficient leg stretching. The leg stretching apparatus includes a fixing plate in which a first fixing plate, which includes a plurality of coupling grooves, and a second fixing plate, which includes a plurality of coupling protrusions corresponding to the coupling grooves, are detachably configured. A fixing part has one end coupled to the first fixing plate and another end equipped with an adjusting part. An elastic string has one end fixed to the fixing part and another end extending in a longitudinal direction of the fixing part, and opposingly branched with two free end portions behind the first fixing plate. A moving part is installed at the second fixing plate to guide the branching of the elastic string.

Abstract:
The present invention relates to an apparatus and a method for scheduling multiple bursts containing a collaborative spatial multiplexing (CSM) burst and a non-CSM burst in a broadband radio communication system. The method comprises the steps of packet-scheduling an uplink data packet corresponding to the bandwidth request from a terminal such that the packet is allocated to either the CSM burst or the non-CSM burst, determining a modulation and coding scheme (MCS) level and a transmission power level corresponding to the packet-scheduled uplink data packet using the maximum number of bytes for each MCS level in accordance with the types of the multiple bursts calculated for the terminal, determining a transmission power offset in accordance with the type of the burst to which the packet-scheduled uplink data packet is allocated using the MCS level and the power transmission level determined in the previous step, and generating MAP information for the terminal, containing burst allocation information of the uplink data packet and information of the transmission power offset determined in the previous step.
Abstract:
Provided is a content reproduction device which enables a user watching or listening to a content on a given content reproduction device to discontinue the watching thereof or listening thereto and then easily resume the watching of the same content or listening thereto from a discontinued state on another content reproduction device. When reproduction of a content is discontinued, discontinued state information indicating a reproduction state of the content at a time point of the discontinuation is transmitted to a watching/listening history management server (20) and the discontinued state information stored in the watching/listening history management server (20) is received from the watching/listening history management server (20), and the reproduction of the content is started from a state determined based on the received discontinued state information.
