Patent number: 7305439Abstract: A group-browsing system for a plurality of clients each including a shared web browser when browsing non-secure parts of a web site. A server is linked to the shared web browser of each client and is configured to monitor the transmission of the web site URL request from the shared web browser of one client of the group and to direct the request to the shared web browser of other clients in the group. A gatekeeper module is configured to first mask the identity of each client's computer on the shared browser. This prevents the web site from retrieving any client's actual identifier. Second, the gatekeeper is also configured to create a same temporary identifier for each client when any client logs on to the web site so that the same web page is displayed for all the clients in the group. When browsing secure parts of a web site, a non-shared web browser is executed instead of using the shared web browser to avoid sharing sensitive or personal information.Type: GrantFiled: February 9, 2006Date of Patent: December 4, 2007Assignee: Net2Phone, Inc.Inventors: Dahong Qian, Matthew Eichner, Feiyu Xie, James Ward, Cheng Zhang

Patent number: 5552883Abstract: Optical and computational components are combined to form a high precision, six degree-of-freedom, single-sided, noncontact position measurement system. Reflective optical targets are provided on a target object whose position is to be sensed. Light beams are directed toward the optical targets, producing reflected beams. Electrical signals are produced indicating the points of intersection of the reflected beams and the position-sensitive detectors. The position sensitive detectors may be lateral-effect photodiodes. The signals are transformed to provide measurements of translation along and rotation around three nonparallel axes which define the space in which the target object moves.Type: GrantFiled: November 21, 1994Date of Patent: September 3, 1996Assignee: Board of Regents, The University of Texas SystemInventors: Ilene Busch-Vishniac, Alvin B.
