20140013432 | METHOD AND APPARATUS FOR VISUALIZING NETWORK SECURITY STATE - A network security state visualization scheme is suitable for collecting security events existing in a network, analyzing the security events, categorizing and contracting the analyzed security events into attack state information, and visualizing the attack state information as a three-dimensional (3D) screen to display the visualized information on a display panel. Unlike the related art where security events are expressed from the viewpoint of IPs, this scheme normalizes collected security event information, analyzes the normalized information, categorizes and contracts the analyzed information into the attack state information, extracts visualization target data, visualizes the visualization target data as the 3D screen, and displays the visualized 3D screen on the display panel. | 01-09-2014 |
20130193983 | JIG FOR MEASURING EMC OF SEMICONDUCTOR CHIP AND METHOD FOR MEASURING EMC OF SEMICONDUCTOR CHIP USING THE SAME - Disclosed are a jig for measuring EMC of a semiconductor chip and a method for measuring EMC that can accurately measure the EMC at a semiconductor chip level. The jig for measuring EMC of a semiconductor chip according to the exemplary embodiment of the present disclosure includes: a chip mount unit on which the semiconductor chip for which the EMC is to be measured is mounted; a memory unit configured to store EMC information of components in a system in which the semiconductor chip is used; and a measurement control unit configured to extract the EMC information stored in the memory unit and provide the extracted EMC information to the chip mount unit at the time of measuring the EMC of the semiconductor chip. | 08-01-2013 |
20120163209 | APPARATUS AND METHOD FOR ANALYZING NETWORK PACKETS BASED ON HISTORY - Disclosed herein is a network packet analysis technology that analyzes packet protocols without having preliminary information about the sequence of network packets, and is capable of analyzing the meanings of fields of each network packet, as well as the temporal sequence of the network packets, using pre-stored history sets. For this, the apparatus for analyzing network packets includes a history set generation unit for capturing and synchronizing network packets, input events and screen shots when an application is running, and then generating a plurality of history sets. A history set storage unit stores the plurality of history sets. A packet analysis unit analyzes the plurality of history sets stored in the history set storage unit and then analyzes a temporal sequence of the network packets and individual fields of each network packet. | 06-28-2012 |
20110125917 | OVERLAY MULTICAST SYSTEM FOR GROUP MEDIA TRANSMISSION APPLICATION SERVICE COMPOSED OF MULTIPLE STREAM - Disclosed is an overlay multicast system for a group media transmission application service composed of a multiple stream, wherein, when an additional stream is newly transferred to a predetermined node in an overlay network, the overlay multicast system transmitting a plurality of streams in the overlay network generates a multiple stream by muxing a main stream inputted from a parent node and the additional stream based on stream correlation information in the predetermined node, and transmits the generated multiple stream to a child node. | 05-26-2011 |
20090238296 | MULTIPLE ACCESS SYSTEM AND METHOD FOR 60 GHZ WIRELESS COMMUNICATIONS SYSTEM - A control apparatus for use in wireless communications includes an antenna unit having antennas, the number of the antennas being equal to a maximum allowable number of connections in a specific frequency band; and a controller for receiving a connection request signal from each terminal attempting to connect to the control apparatus via the antenna unit, and transmitting and receiving a data signal to and from each terminal connected to the control apparatus by using a multiple-input-multiple-output scheme. The controller transmit and receive the data signal to and from each terminal connected to the control apparatus by obtaining a signal value of each antenna based on a predicted channel matrix and the number and types of terminals connected to the control apparatus via the antenna and separating the data signal for each terminal from the signal value according to the multiple-input-multiple-output scheme. | 09-24-2009 |
20080240547 | Apparatus And Method For Vision Processing On Network Based Intelligent Service Robot System And The System Using The Same - There are provided an apparatus and method for vision processing on a network based intelligent service robot system and a system using the same. A robot can move to a target object, avoiding obstacles without helps of a robot server interfaced with a robot terminal over network, by extracting/processing three-dimensional distance information of external objects, using a stereo camera, a low price image processing dedicated chip and an embedded processor. Therefore, the intelligent robot can travel and move using only a stereo camera image processing without other sensors, and further provides users with various functional services with low expense. | 10-02-2008 |
