20080207115 | SYSTEM AND METHOD FOR PLAYING AUDIO FILE ACCORDING TO RECEIVED LOCATION INFORMATION - A system and method for playing an audio file, and for providing a user with information on the other party's location by playing an audio file are disclosed. The system is provided with a first audio player and a second audio player, and each audio player is provided with a transceiver unit to receive a message regarding sharing of an audio file and location information transmitted from the other audio player; a location-sensing unit to sense relative location of the two audio players, i.e., the first audio player and the second audio player, based on received location information; a wireless communication unit to receive the audio file transmitted from the other audio player; and a play-management unit for playing the audio file if the sensed relative location is within a short distance. | 08-28-2008 |
20090002377 | APPARATUS AND METHOD FOR SYNCHRONIZING AND SHARING VIRTUAL CHARACTER - An apparatus and method for synchronizing and sharing a virtual character are provided. The method includes generating a virtual character, synchronizing content in a predetermined form with the generated virtual character; converting the virtual character into an extensible markup language (XML)-based file and storing the XML-based file. | 01-01-2009 |
20090025539 | METHOD AND DEVICE FOR SELECTING MUSIC TO BE RECOMMENDED FOR USER BY USING MUSIC REPRODUCTION DEVICE - A music reproduction device for recommending music suitable for a taste of a user is provided. When the music reproduction device reproduces music, a motion of the user is measured. A range of a tempo in which a tempo of music is matched with a tempo of the motion of the user is determined as a range of a preferred tempo of the user. Pieces of music to be recommended for the user are selected based on the determined range of the tempo. Thus, it is possible to accurately recommend pieces of music suitable for the taste of the user without an additional input for generating a recommendation list by the user. | 01-29-2009 |
20090096357 | ORGANIC LIGHT EMITTING DEVICE - An organic light emitting device that obtains stable image qualities through prevention of any significant decrease in brightness at high temperature. The organic light emitting device includes an anode; a cathode facing the anode; an organic emitting layer interposed between the anode and the cathode; an electron transport layer interposed between the organic emitting layer and the cathode and comprising an alkali metal compound or an alkali earth metal compound; and a buffer layer interposed between the organic emitting layer and the electron transport layer. | 04-16-2009 |
20090153025 | METHOD OF MANUFACTURING ORGANIC LIGHT EMITTING DISPLAY APPARATUS - A method of manufacturing an organic light emitting display apparatus, the method including: forming an organic light emitting device including a first electrode, a second electrode, and an intermediate layer between the first electrode and the second electrode, on a substrate, the intermediate layer including an organic light emitting layer and an electron transport layer (ETL) containing an alkali metallic compound on the organic light emitting layer; sealing the organic light emitting device; and aging the organic light emitting device, wherein the aging includes thermal treatment at a temperature from about 80 to about 150 degrees C. | 06-18-2009 |
