Patent number: 11768015Abstract: The present disclosure relates to an absorption cooling machine including an absorber, a first regenerator, a second regenerator, a condenser, an expansion device, and an evaporator, and relates to a cooling machine that connects a bypass collection pipe that guides an absorbent flowing back into the second regenerator to be collected into an absorber to a second collection pipe, in order to prevent the water level of the second regenerator from being raised as the absorbent cannot be collected by the absorber and flows back to the second regenerator, due to the pressure difference between an absorbent separated from the first regenerator and collected into the absorber through the first collection pipe, and an absorbent separated from the second regenerator and collected into the absorber through the second collection pipe.Type: GrantFiled: January 14, 2021Date of Patent: September 26, 2023Assignee: LG ELECTRONICS INC.Inventors: Heungju Lee, Yongsun Cho, Jaeseo Lee

Patent number: 9654490Abstract: A system and method for fuzzing a network application program, which use a captured packet upon fuzzing a network application program, and thus neither a protocol analysis procedure nor the production of a fuzzer program is required. The system for fuzzing a network application program includes a fuzzing performance client program unit for generating a packet to be transmitted from a captured packet, applying a fuzzing rule to the packet to be transmitted, and outputting a resulting packet. A fuzzing supervisor program unit provides the packet from the fuzzing performance client program unit to a target program to be fuzzed, monitors an event and abnormal termination of the target program to be fuzzed, and analyzes a situation of termination to verify security vulnerabilities if abnormal termination has occurred.Type: GrantFiled: December 5, 2014Date of Patent: May 16, 2017Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Dong Geun Kim, Byung Jun Lim, Jong-Myoung Kim, Jaeseo Lee, Su Yong Kim

Patent number: 9444830Abstract: A security management apparatus and method for a web server/web application server is provided. The security management apparatus includes a connection state table storage unit for, as a web client accesses a web server/web application server, storing connection state information, an access time, and a connection policy. A connection state information inspection unit inspects whether current connection state information is present in connection state information of the connection state table storage unit in which the connection policy is set to blocking. If current connection state information is not present, a web session reuse attack determination unit determines whether a current connection is a web session reuse attack. If the current connection is not the web session reuse attack, an attack pattern analysis unit analyzes whether an attack pattern is present. A blocking unit blocks a connection between the web client and the web server/web application server.Type: GrantFiled: September 5, 2014Date of Patent: September 13, 2016Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jong-Myoung Kim, Jaeseo Lee, SuYong Kim
