Patent number: 6583808Abstract: A system and method for stereoscopic video teleconferencing provides an immersive virtual meeting experience. Each participant is surrounded by at least two video cameras. The system senses the position of each of the participants and uses this information to select, for each participant, camera pairs to capture a stereo pair of video images of each of the other participants. The system is adapted to isolate the image of each participant from the background. The system transforms the stereo pair images to adjust the perspective for the interocular spacing of each participant. The processed stereo pairs of video images are transmitted to the respective participants. For each participant, the system assembles a stereo video display image of a virtual meeting room, combining the stereo pair images of each of the other participants appropriately sized and positioned. Three-dimensional (3D) virtual objects can also be displayed and manipulated by participants.Type: GrantFiled: October 4, 2001Date of Patent: June 24, 2003Assignee: National Research Council of CanadaInventors: Pierre Boulanger, Guy Godin

Publication number: 20020150558Abstract: The subject of the present invention is the use of a polypeptide comprising at least 6 continuous amino acids of the sequence as shown in the sequence identifiers 1 to 5 as cellular receptor and/or coreceptor for adenoviruses. It also relates to the use of a cell capable of expressing such a polypeptide as well as that of a ligand capable of influencing the attachment of an adenovirus to a host cell and/or its entry into the said host cell. Finally, it also relates to a method for selecting or identifying a cellular receptor for a virus or the part of a viral protein which determines the attachment of the virus to its cellular receptor as well as to the use of a bifunctional ligand to target an adenovirus to a host cell carrying, at its surface, a surface protein other than the natural cellular receptor for the said adenovirus.Type: ApplicationFiled: May 30, 2002Publication date: October 17, 2002Inventors: Pierre Boulanger, Saw See Hong, Lucie Karayan

Patent number: 6009359Abstract: A mobile mapping system is designed to generate a geometrically precise three-dimensional detailed model of an unknown indoor environment. There is no limit on the distance the mobile system may travel, nor on the type of details that can be mapped. The same design is used for environments ranging from simple office hallways to long winding underground mine tunnels. Surfaces and features can be mapped from images acquired by a unique configuration of different types of optical imaging sensors and positioning devices. This configuration ensures that all the information required to reconstruct the three-dimensional environment is included in the collected images. Provided a sufficient overlap between two-dimensional intensity images and combining such with three-dimensional range images, the method reconstructs an environment by adjusting a plurality of images simultaneously.Type: GrantFiled: September 18, 1996Date of Patent: December 28, 1999Assignee: National Research Council of CanadaInventors: Sabry F. El-Hakim, Pierre Boulanger

Patent number: 4680468Abstract: A detector for charged particles, i.e. secondary electons ir ions emitted from a bombardment area of a specimen in an instrument such as a scanning electron microscope or analytical instrument, consists of a collector, e.g. a scintillation surface highly charged with a voltage of the opposite polarity from that of the particles, for receiving the particles and providing an output proportional to the number thereof. A grid, charged with a voltage of the same sign as the scintillation surface, but to a lower value, is located between the scintillation surface and the bombardment area, and a probe in the form of a wire electrically connected to the grid projects into the vicinity of the bombardment area which is in a confined space between the specimen and the instrument. The result is to set up an electrostatic field around the wire, causing a significant number of the charged particles to orbit the wire and travel to the scintillation surface.Type: GrantFiled: August 5, 1985Date of Patent: July 14, 1987Assignee: Canadian Patents and Development Limited-Societe Canadienne des Brevets et d'Exploitation LimiteeInventors: Claude Bouchard, Pierre Boulanger
