Patent number: 11872068Abstract: The X-ray imager combines a pulsed X-ray source with a time-sensitive X-ray detector to provide a measure of ballistic photons with a reduction of scattered photons. The imager can provide a comparable contrast-to-noise X-ray image using significantly less radiation exposure than conventional X-ray imagers, notably about half of the radiation.Type: GrantFiled: October 29, 2019Date of Patent: January 16, 2024Inventors: Rejean Fontaine, Julien Rossignol, Yves Bérubé-Lauzière

Patent number: 8297971Abstract: A dental tartar detection system (10), especially for detection of subgingival tartar (S), comprises a probe (12) adapted to be displaced along a tooth (T) an illumination system (14) for illuminating with an incident light a region on the tooth (T), a detection system (16) for collecting the light reflected thereat, and an analysis system (34) for providing a signal to an operator of the probe (12) when measurements on the reflected light in one or more predetermined range of wavelengths fall within any predetermined range of values that are characteristic of tartar (S). Typically, the detection of tartar (S) is achieved on the basis of the possible colors that tartar (S) can have such that the aforementioned one or more predetermined range of values cover wavelengths associated with colors of tartar (S).Type: GrantFiled: December 29, 2010Date of Patent: October 30, 2012Assignee: Dentsply Canada Ltd.Inventors: Yves Berube-Lauziere, Naim Karazivan, Emmanuel Montini, Sophie Bernier, Marc Levesque, Yvan Mimeault, Michel Doucet

Patent number: 7366333Abstract: There is provided a method and system for positioning a mammal for optical imaging in which a digital image of the mammal is obtained using a camera and a region of interest is selected using the digital image. The selected region is registered with an optical imaging system and the mammal is positioned in the imaging system to image the selected region of interest.Type: GrantFiled: July 23, 2003Date of Patent: April 29, 2008Assignee: ART, Advanced Research Technologies, Inc.Inventors: William F. Long, Yves Bérubé-Lauzière, Laura McIntosh

Patent number: 7044165Abstract: An outflow regulator for a gravity-fed liquid outlet of a liquid reservoir comprising a restriction plate mountable within the liquid outlet for limiting a flow rate of an effluent. The restriction plate allows a lower passage for the effluent when a first level of liquid is reached within the liquid reservoir, and an upper passage for the effluent when a second level of liquid is reached. The regulator also comprises a flapgate pivotable between a closed position where the flapgate covers the lower passage of the restriction device and an open position away from the restriction plate. When the flapgate is in the closed position, the effluent is free to flow out though the upper passage. A float counterweight switches the flapgate between the opened position and closed position according to the liquid level in the reservoir.Type: GrantFiled: August 15, 2005Date of Patent: May 16, 2006Assignee: Premier Tech Technologies Ltd.Inventors: Marc-André Malenfant, Yves Bérubé, Nicolas Viel, Jean-Pierre Dautais

Patent number: 6992762Abstract: There is provided a method and system for collecting optical data for use in time resolved optical imaging wherein light is directionally propagated through free-space optics to impinge on a plurality of illumination at the surface of a biological tissue such as that comprised in small animals. Light re-emitted from the tissue is collected and directionally propagated through free space optics towards a detector to produce time resolved optical signals useful for optical image reconstructions.Type: GrantFiled: September 22, 2003Date of Patent: January 31, 2006Assignee: ART Advanced Research Technologies Inc.Inventors: William F. Long, Yves Bérubé-Lauzière, David J. Hall, Laura McIntosh

Patent number: 6886588Abstract: A buoyancy flushing apparatus is disclosed which comprises a reservoir for accumulating liquid, having an inlet for receiving liquid and an outlet chamber recessed in a bottom wall of the reservoir. The outlet chamber includes an outlet for draining liquid out of the reservoir. The apparatus further comprises an outlet valve movable between a down position where liquid accumulates in the reservoir and a raised position where liquid accumulated in the reservoir is flushed out via the outlet. The outlet valve comprises a ballast unit sized and shaped to fit loosely in the outlet chamber when said valve is in the down position; and a float unit topping the ballast unit to move the valve in the raised position by buoyancy when a sufficient amount of liquid is accumulated in the reservoir, thereby providing a passageway for liquid between the bottom wall of the reservoir and the valve leading to the outlet in the outlet chamber to flush liquid out of the reservoir.Type: GrantFiled: September 17, 2003Date of Patent: May 3, 2005Inventors: Marc-André Malenfant, Yves Bérubé, Nicolas Viel, Roger Lacasse, Jean-Pierre Dautais
