Title: The control method of traffic service by fast handoff in Highspeed communication system
Inventor: CHOI SEONG GU
IPC: H04B7/26
Filed: 2002-12-24
Abstract: PURPOSE: A method for controlling a traffic service through a fast handoff in a high speed communication system is provided to improve the QoS(Quality of Service) of a traffic service by simplifying a handoff procedure in order to minimize the transmission delay or loss of data. CONSTITUTION: An AT(Access Terminal) receives a call signal from the presently connected AP(Access Point) and checks the strength of the received signal(S310,S311). If the strength of the received signal is below a preset level, the AT checks the strength of the signals received from other peripheral APs(S313). If an AP having the strongest signal strength is sensed, the AT judges and selects the AP as an AP to hand off(S314). The AT sends the information of the selected AP and its own IP information in order to request the presently connected AP to handle the handoff of the AT(S315). The presently connected AP transmits the handoff request message to a PAR(Packet Access Router)(S316). The PAR, after checking whether the selected AP has a radio resource for the handoff of the AT, requests the selected AP to allocate a channel(S317).

Abstract: PURPOSE: A method and an apparatus for driving a plasma display panel are provided to display inputted images by using a selective write method and a selective erase method. CONSTITUTION: One of an AV(Audio/Video) signal and a PC(Personal Computer) signal is inputted into a plasma display panel(S30). The inputted signal is decided as one of the AV signal and the PC signal(S32). A driving process using one of a selective write method and a selective erase method is performed by deciding one of the AV signal and the PC signal(S34,S36). The plasma display panel is driven by the selective erase method when the inputted signal is the AV signal. The plasma display panel is driven by the selective write method when the inputted signal is the PC signal.

CONSTITUTION: The method comprises steps of (a) mixing a functional material (11) with an aqueous solution of a surfactant with stirring to emulsify; (b) forming an outer wall of a capsule (13) on the outer part of the functional material by adding an outer wall forming material selected from a melamine initial condensate, a gelatin, an urethane and an epoxy to the emulsified material of the step (a) to prepare a micro-capsule (10); (c) adding an Ag nano-particles dispersed solution to a mixture solution of water and 3-6 wt.% of a water soluble polymer of a styrene maleic anhydride having a structure of the formula 1 with stirring; and (d) after adhering the Ag nano-particles of the solution of the step (c) to the outer wall of the capsule, hardening it.

Abstract: PURPOSE: An emergency measures-control method for a washing machine is provided to prevent the pollution and damage of the laundry by using the washing machine again by emergency measures before a broken drain valve is repaired. CONSTITUTION: An emergency measures-control method for a washing machine for transmitting and receiving data with a service server by on-line through a network is composed of steps for continuously detecting if a drain valve is broken down(S21); informing a user that the drain valve is broken down and guiding to download an emergency measures program(S23); connecting the washing machine to the on-line service server if the user demands to download the emergency measures program(S26); receiving an emergency measures program data for the breakdown of the washing machine from the service server(S27); and executing the program according to the received data(S28).
