Abstract: The present invention relates to the formation by a communication relay server of a communication pathway between a terminal and a service provider server. It relates to a communication relay system, server and method for same, wherein, when a terminal accesses a service provider server, the communication relay server uses virtual information such as path ID, etc., to form a communication pathway so that terminal identification information such as telephone number, etc., may not be directly exposed, and the communication pathway that is formed between the terminal and the service provider server may also be changed to a communication pathway that is formed between another terminal and the service provider server.

Abstract: Disclosed is a cover plate for a lighting fixture and a lighting fixture having the same, which achieves superior light diffusivity and light uniformity as well as superior light transmission in comparison with the prior art, thereby improving a luminance characteristic. The cover plate is arranged at an exterior of an light source of the light fixture so as to exit lighting emitted from the light source outward. The cover plate is made of light transmissive resin material having 5-35% of bubbles for light scattering, which has a diameter within a range of 60 ?m˜700 ?m, and exits light emitted from the light source while diffusing the light to the whole area of the cover plate.

Abstract: Disclosed herein is a system and method for virtual martial arts sparring using a network. The system includes a user terminal, a network server, data management means, and a network administrator terminal. The user terminal accesses the Internet to exchange user information with a network server, receives sparring partner information to retrieve and select a discipline, a grade, an area and sex-specific sparring conditions, receive sparring progress information according to the selected sparring condition, and perform a sparring function. The network server includes user information management means, sparring partner information management means, sparring progress information management means, image information management means. The data management means includes a user information database (DB), a sparring partner information DB, a sparring progress information DB, and an image information DB, and inputs and outputs the information.

Abstract: Disclosed herein is a system and method for virtual martial arts training using a network. The system includes a user terminal, a network server, a data management unit, and a network administrator terminal. The user terminal exchanges user information with a network server, selects a training discipline and grade or an examination discipline and grade, and transmits a difference value and a correction value together with a user motion image. The network server includes user information management means, training information management means, examination information management means, examination and determination management means, image information management means, and communication means. The data management means includes a user information database (DB), a training information DB, an examination information DB, an examination and determination DB, and an image information DB, and inputs and outputs the information.

Abstract: A mitral cerclage annuloplasty apparatus comprises a tissue protective device and a knot delivery device. The tissue protective device comprises a first protective tube and a second protective tube. The knot delivery device comprises a tube wherein a loose knot is looped around its distal end through a hole and wherein tight knot is formed when the distal end of the tube is cut open. Alternatively, the knot delivery device comprises an inner tube and outer tube. The inner tube is insertable and rotatable inside the outer tube. When the tubes are in a closed position by rotating either the outer tube or the inner tube, a hole is created near its distal end. When the tubes are in open position by rotating either the outer tube or the inner tube, the hole joins the opening of the outer tube and lengthens.

Abstract: A bowl-shaped cover (1) with a hole at the bottom replaces the cover with a sound hole of the conventional earphone, thus creating a constant space. The earphone sound vibrates the cover (1) by beating the inside of the cover (1) and then the vibration is transmitted to a rubber drumhead (vibrating membrane) (2) which is attached onto the cover (1). The rubber drumhead (vibrating membrane) (2) of the earphone works as a soft earmuff and makes wearing feel soft and comfortable. The present invention relates to the earphone that converts sound into vibration and also isolates sound.

Abstract: A method and a system for exchanging electronic information data, using a color code recognition device are provided. An electronic information data from the first computer is recognized in either in the ASCII code or in the binary digit format. The electronic information data is encoded by substituting each character of the ASCII codes or the binary digit recognized with a color value. The encoded data is transmitted to the second computer, and the transmitted data is decoded into the original electronic information data. The system for exchanging an electronic information data includes a storage device for storing the user identification database and the legend database, an encoding device for encoding the electronic information data, a decoding device for decoding the encoded data to restore the encoded data into its original format, and a network device for transmitting the data between a plurality of computers over the network.
