Patent number: 8429959Abstract: Disclosed are an apparatus and method for testing braking performance. The apparatus of the disclosed invention comprises: a driving unit which generates power; a test unit driven by the driving unit; and a control unit which controls the operation of a braking apparatus to generate a brake force on the test unit and to check braking performance. The present invention uses a rope unit moving at a speed for inducing a braking operation by the rotation of driving sheaves spaced apart from each other, rather than testing braking performance in an expensive elevator test tower, thereby preventing the possible dangers of tests conducted in said test tower. Further, the present invention controls loading capacity simply by controlling the loads of the driving unit to enable easy testing.Type: GrantFiled: January 19, 2010Date of Patent: April 30, 2013Assignee: Gumyoung General Co., Ltd.Inventors: Gum Gee Lee, Yong Soo Jang, Hyun Kyu Cho

Patent number: 7509426Abstract: A system and method for aborting web services automatically. An application program container has a first web service application program embedded, intercepts a message that is transmitted and received between a second web service program located externally and the first web service application program, identifies the kind of an operation requested by the second web service application program, and keeps information required for compensation. A protocol manager generates and manages a first sub-transaction object by a request of the second web service application program. A local compensator compensates the first sub-transaction if a global transaction coordinator sends a command to compensate a second sub-transaction already committed. A protocol service unit transmits and receives messages for managing the first sub-transaction. A registration service unit registers the generated first sub-transaction with the global transaction coordinator.Type: GrantFiled: November 16, 2004Date of Patent: March 24, 2009Assignee: Electronics and Telecommunications Research InstituteInventors: Chan Kyu Park, Daeha Lee, Jin Young Moon, Byoung Youl Song, Rockwon Kim, Seung Woo Jung, Hyun Kyu Cho, Ho Sang Ham, Yoon Joon Lee, Jungsook Kim, Seunglak Choi, Hyukjae Jang, Hangkyu Kim

Publication number: 20050081039Abstract: Disclosed is a method for creating and verifying SOAP messages in web service security using signature encryption. The SOAP message sender encrypts a signature used for SOAP message security with a secret key for encrypting data to be contained in the SOAP body. The encrypted signature is inserted in the security header of the SOAP header and sent to the recipient. The SOAP message recipient decrypts the encrypted key with his/her private key and restores the secret key. The restored secret key is used to decrypt the encrypted signature in the security header of the SOAP header, and the decrypted signature is used to verify the SOAP message.Type: ApplicationFiled: December 31, 2003Publication date: April 14, 2005Inventors: Dae-Ha Lee, Chan-Kyu Park, Rock-Won Kim, Jin-Young Moon, Byoung-Youl Song, Seung-Woo Jung, Hyun-Kyu Cho, Ho-Sang Ham

Patent number: 6266680Abstract: A method for electronically checking documents as to their authenticity is disclosed, in which an official seal is not put on the document, but the document itself shows to be notarized, and the authenticity of a document can be electronically confirmed. The method for electronically checking the authenticities of documents includes the step of forming a document with an electronically authenticity-checking format for showing that a document has been notarized without using an official seal (first step). It further includes the step of judging as to whether the document with the electronically authenticity-checking format has been really notarized (second step). Therefore, a notarization feature can be provided even to facsimile documents and to printed-out documents. Therefore, a document having a notarization feature can be transmitted even to a remote place, thereby preventing forgery of documents.Type: GrantFiled: January 2, 1998Date of Patent: July 24, 2001Assignee: Electronics and Telecommunications Research InstituteInventors: Byoung Youl Song, Hyeon Sung Cho, Kyeong Ho Lee, Hyun Kyu Cho, Ho Sang Ham
