Patent number: 9649238Abstract: A portable chamber for hyperbaric and/or hypoxic treatment comprises an open-ended and typically frustro-conical tubular body sized to accommodate at least one occupant, and two end members configured to be respectively received at opposite extremities of the body for closing the body in a seal tight arrangement. The body of the chamber is made of a flexible yet reinforced elastomeric material such as to be collapsible during transport. One of the end members is provided with a door to provide access to the interior of the chamber. The extremities of the body are substantially spherical such as to receive the correspondingly substantially periphery of the end members. When the chamber is supplied with gases during hyperbaric or hypoxic treatment, the spherical peripheries of the end members are urged against the spherical extremities of the body, thereby providing a seal tight chamber. A treatment system comprising the chamber is also disclosed.Type: GrantFiled: October 27, 2010Date of Patent: May 16, 2017Assignee: GROUPE MEDICAL GAUMOND INC.Inventors: André Dubois, Richard Langlois, Claude Gaumond

Publication number: 20070117110Abstract: Disclosed herein are two methods for rapid multiplex analysis to determine the presence and identity of target DNA sequences within a DNA sample. Both methods use reporting DNA sequences, e.g., modified conventional Taqman® probes, to combine multiplex PCR amplification with microsphere-based hybridization using flow cytometry means of detection. Real-time PCR detection can also be incorporated. The first method uses a cyanine dye, such as, Cy3™, as the reporter linked to the 5? end of a reporting DNA sequence. The second method positions a reporter dye, e.g., FAM, on the 3? end of the reporting DNA sequence and a quencher dye, e.g., TAMRA, on the 5? end.Type: ApplicationFiled: June 16, 2006Publication date: May 24, 2007Inventors: Shanavaz Nasarabadi, Richard Langlois, Kodumudi Venkateswaran

Patent number: 7038462Abstract: Improved methods and apparatus is disclosed for electrical testing of electronic circuits such as those existing in microcircuit devices including chip carriers, printed circuit boards and substrates. The invention provides for the testing of the continuity of electronic circuits in progressively smaller devices having increased density of circuits and having pads closely spaced. A quasi-fluidized bed of conductive particles is provided for effectively contacting pads on a first side of a substrate. Pads on another side of the substrate which are connected to the pads on the first side are then contacted by a test device. The circuit interconnecting respective pads on the two sides of the substrate can then be assessed for electrical continuity.Type: GrantFiled: June 22, 2004Date of Patent: May 2, 2006Assignee: International Business Machines CorporationInventors: David Danovitch, Richard Langlois, Martin Lapointe, Robert-Paul Leclerc
