Patent number: 8825855Abstract: A method and apparatus for Single Sign-on, wherein the user accesses a platform server and at least one service provider on the platform server. The method includes intercepting a request sent by the user via a client browser and extracting a domain name included in the request. If the domain name is an original domain name of the platform server, a global session ID is generated for uniquely identifying a session between the user and the platform server. A new domain name of the platform server associated with the global session ID is generated and the URL in the request is redirected to a new URL including the new domain name of the platform server. The request, including the new URL of the platform server, is forwarded to the platform server.Type: GrantFiled: August 14, 2012Date of Patent: September 2, 2014Assignee: International Business Machines CorporationInventors: Chen Hua Feng, Kai Tang, Yun Tao Wang, Jian Ming Zhang

Patent number: 5704859Abstract: A new type of the compact freewheel body for bicycle includes a freewheel casing, a ball seat, a hub, two rows of steel balls, an adjusting ring and a clutch located in the hub. The ball ring at the top of a convention freewheel casing is moved to the bottom to become a ball seat. The distance between two rows of steel balls is increased. The freewheel body can be made more compact. Smaller gear seat may be used and thus increasing the speed ratio and improving mechanical strength of the gear set. The wobbling of the freewheel can be effectively reduced to make the freewheel running and gear shifting smoother and more reliable.Type: GrantFiled: October 16, 1996Date of Patent: January 6, 1998Assignee: National Science Council of Republic of ChinaInventors: Chen-Hua Feng, Ching Huan Tseng, Shyh-Haur Su
