Patent number: 10001564Abstract: An embodiment disclosed a system for collaborative positioning calibration, comprising at least one reference station and at least one client. The reference station uses a known position and a satellite signal transmitted by at least one satellite to compute a pseudo-range difference of the reference station position and the satellite position, and then broadcasts an area calibration data including at least one pseudo-range difference to at least one client. Based on the area calibration data, the client computes at least one pseudo-range calibration data and outputs a calibrated position of global positioning system.Type: GrantFiled: October 24, 2013Date of Patent: June 19, 2018Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Jing-Shyang Hwu, Kuan-Lin Chiu, Yung-Cheng Chao

Patent number: 8050229Abstract: The present invention is directed to an apparatus and method for IP mobility management for persistent connections. Without affecting the applications on the network domain, it provides for domain hand-off for a mobile node so that the mobile node can maintain the persistent connection. The mobility management apparatus may comprise a Mobility-Aware Socket module (MAS) and one or more mobility management servers. Each mobility management server communicates with a corresponding mobile node. When a mobile node roams from a first network domain to a second network domain, the mobile node and its target mobile nodes execute the MAS module to support the mobility management for persistent connections through their corresponding mobility management servers.Type: GrantFiled: March 31, 2007Date of Patent: November 1, 2011Assignee: Industrial Technology Research InstituteInventors: Yu-Ben Miao, Tai-Xing Yu, Jing-Shyang Hwu, Ce-Kuan Shieh, Tzu-Chi Huang, Bo-Yang Lai
