Abstract: Provided is a flow generation method for Internet traffic measurement. In the flow generation method, dependency between packet collecting time and flow generating time is removed using a virtual timer and a flow generation completion processing interval is controlled to skip by a unit time in response to a user's request. Also, a fragmented packet processing method is selectively used at need and a FIN timeout is applied selectively to a timeout mechanism used in flow generation completion. Thereby, this invention can improve accuracy and efficiency of Internet traffic measurement.

The iris identification system comprising a characteristic vector database (DB) for pre-storing characteristic vectors to identify persons; an iris image extractor for extracting an iris image in the eye image inputted from the outside; a characteristic vector extractor for multi-dividing the iris image extracted by the iris image extractor, obtaining a iris characteristic region from the multi-divided each iris image, and extracting a characteristic vector from the iris characteristic region by a statistical method; and a recognizer for comparing the characteristic vector DB thereby identifying a person.

Abstract: A method and apparatus for controlling a SAR (Specific Absorption Rate) in a mobile communication terminal. The SAR is controlled by adjusting a transmission power of a mobile communication terminal. The method for controlling the SAR in a mobile terminal includes the steps of checking a user-selected SAR control mode of the mobile terminal, setting a code value corresponding to a transmission power of the RF signal to a gain of the amplifier, wherein the code value is set to a first code value when the SAR control mode is a safe mode, or is set to a second code value when the SAR control mode is a normal mode, and amplifying the RF signal according to the gain of the amplifier, such that it controls a transmission power of an RF (Radio Frequency) signal by controlling a gain of an amplifier amplifying the RF signal.

Abstract: A method of providing a Karaoke service to mobile terminals through wireless connection between them. The mobile terminals are grouped as a service group and one of them is designated as a master mobile terminal and the other mobile terminals as slave mobile terminals. The master mobile terminal is connected to a Karaoke service provider through a mobile communication network and controls service content to be received from the Karaoke service provider in all the mobile terminals of the service group. If the master mobile terminal transmits a play command to the slave mobile terminals, all the mobile terminals start to play Karaoke music according to the service contents.

Abstract: Portable communication terminal and a method for displaying image files of a background picture using the same.

Abstract: A washing machine has a door mounted for rotation between open and closed positions. An electrical solenoid is connected to the door by means of a wire so that when the wire is pulled by the solenoid, the door is opened from a closed position, or closed from an open position. A torsion spring is connected to the door for storing energy while the door is being opened or closed, and then releasing the stored energy to maintain the door in the open or closed position. The wire is flexible to enable the door to be manually opened without actuating the solenoid.
