Patent KR-20010016275-A (KR)
Inventor: KIM HYEONG MO
IPC: H04N7/18
Filed: 2000-11-29
Abstract: PURPOSE: A dynamic fusion detector algorithm is provided so that high security can be achieved by preventing mis-operation of systems due to a fluorescent lamp, headlight of vehicles, etc. CONSTITUTION: In a system for sensing environmental variations, a current list box values consecutively store RGB averages of the respective blocks of a current frame at intervals of a predetermined period, and old list box values store RGB averages of the respective blocks of a 3 frame preceding frame. The current list box values are sequentially compared with the old list box values. When the resultant value exceeds a critical value, movement of an object on a screen can be sensed. As compared with general sensing systems mis-operated due to non-sensing factors, such as a fluorescent lamp, headlight of vehicles, lighter, candle light and sunlight, the dynamic fusion detector algorithm has excellent sensing reliability, accuracy and security, and thus is suitable for coast line sensing systems and bank security systems. In addition, the dynamic fusion detector algorithm senses variations of sunlight, and thus reduces or prevents fire.

Title: Method for Concurrent Servicing in Mobile Communication System
Inventor: JANG UN SEOK
IPC: H04B7/26
Filed: 2000-12-20
Abstract: PURPOSE: A simultaneous service method in a mobile communication system is provided to transmit packet data to a destination mobile station timely and provide the continuity of a service being provided to a subscriber by setting up a simultaneous service by adding a procedure for re-activating the packet data on the interface between a base station controller and an exchange when destination packet data is generated from a network to the mobile station which is available for the simultaneous service set-up. CONSTITUTION: A point-to-point protocol(PPP) is set-up between a mobile station and a packet data serving node(S21). A PDSN which has received packet data to be destined to the mobile station transmits a destination packet data traffic to the PCF(S22). The PCF recognizes that the mobile station is in a dormant state and transmits a 3G-IOS A9-base station controller service request message to the BSC to re-activate a packet data service(S23). The BSC transmits a 3G-IOS additional service request message to an exchange to additionally establish a packet data call(S24). The exchange transmits a 3G-IOS assignment request message requesting a radio resource assignment for the additional packet data service and an A8 interface connection between the BSC and a PCF(Packet Control Function) to a base station controller(BSC)(S25). The BSC transmits a 3G-IOS A9-base station service response message to the PCF to inform that the packet data re-activation proceeds(S26). The BSC transmits a call assignment message of the radio interface standard so that the mobile station can process a call for the re-activated packet data service(S27). The BSC transmits one of SCM(Srvice Connection Message), a GHDM(General Handoff Direction Message) and UHDM(Universal Handoff Direction Message) to the mobile station to initiate a service option connection set-up for the additional packet data service with the mobile station(S28). The mobile station proceeds a service negotiation procedure(S29) and transmits a service connection completion message to the BSC(S30). The BSC transmits a 3G-IOS A9/A8 set-up message to the PCF to request a packet bearer connection set-up of the A8 interface(S31). The PCF transmits a 3G-IOS A9/A8 connection message to inform that the packet bearer of the A8 interface has been completely set up(S32). The BSC transmits a 3G-IOS assignment complete message to inform that the packet data service is ready(S33). The mobile station is provided with the additional packet data service simultaneously with the voice call service which has been provided, and the PCF transmits the packet data to the destination mobile station(S34).

Abstract: PURPOSE: A method for configuring QoS(Quality of Service) FEC(Forwarding Equivalence Class) and searching packets to classify and transmit emulated leased line service packets in an MPLS(Multi Protocol Label Switching) edge router is provided to search multiple fields of a packet header by multistage with configuring forwarding data tables and search tables, thereby providing a high-quality emulated leased service through an MPLS network. CONSTITUTION: If a packet is input(41), a destination address, a destination net mask, a source address, and source net mask data are extracted from a header of the packet(42). A search table 1 for an emulated leased line service is searched by using a longest prefix matching method with source net mask as key value to find out a source address identifier(43). A search table 2 for an emulated leased line service is searched by using the longest prefix matching method with the destination address and destination net mask source net mask as key value to find out a destination address identifier(44). A search table 3 for an emulated leased line service is searched by using an exact matching method with the source address identifier and the destination address identifier as key value to find out output label and output interface from a search table 4(45). An MPSL header stating the output label is attached to the packet(46). The packet is transmitted through the output interface(47).

CONSTITUTION: The member is integrally formed by molding, having an incident plane 105a and an outgoing plane 105b of light respectively at both end faces in the direction of the optical axis N; in the area including the optical axis N of the incident plane 105a and the outgoing plane 105b, a three-beam diffraction grating 105h and a first diffraction grating 105f are formed; and the area other than each diffraction grating of the incident plane 105a and the outgoing plane 105b is used as a reference plane for mirror finish.
