Publication number: 20100223320Abstract: In one embodiment, an online collaborative computing session is initiated between a presenter device and a plurality of attendee devices via a server in a computer network. The server distributes session data from the presenter device to the plurality of attendee devices. To decrease the amount of traffic in the network, at least one of the plurality of attendee devices may be selected as a super node, where each super node is then responsible for one or more corresponding attendee devices of the session. The session data is received at the super nodes and distributed from the super node to its one or more corresponding attendee devices.Type: ApplicationFiled: February 27, 2009Publication date: September 2, 2010Inventors: He Huang, Jian Lin, Zheng Yuan, Defeng Lu

Patent number: 7736445Abstract: A surface treatment method for solder joint employs alkali buffer solution dipping the solder joint and the alkali buffer solution reacts with the solder joint thus yielding a passive layer. As the resultant passive layer forms on the surface of the solder joint, thereby prevents further corrosion and dissolution during aqueous cleaning or water dipping thereafter. In addition, the passive layer ensures a good appearance with maximum protection of the solder joint and also provides a sound reliability and a high testability of a finished electronic product equipped with the solder joint.Type: GrantFiled: August 15, 2007Date of Patent: June 15, 2010Assignee: SAE Magnetics (H.K.) Ltd.Inventors: Ichiro Yagi, DeFeng Lu, XiaoGang Yang, DeYu He
