Patent number: 11448636Abstract: Magnetic chip detectors for detecting magnetic chips in a lubrication fluid are provided. The chip detector includes a first electric terminal, a second electric terminal and a magnet. The second electric terminal is spaced apart from the first electric terminal to define a gap between the first and second electric terminals. The gap exposes a cavity formed in the magnet for collecting magnetic chips. The cavity accommodates the accumulation of smaller and relatively harmless magnetic chips without triggering an alarm to reduce the occurrence of nuisance alarms.Type: GrantFiled: September 29, 2020Date of Patent: September 20, 2022Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Alan Padilla Martinez, Pierre Castonguay, Hubert Caron-Saint-Georges

Patent number: 8294808Abstract: A dual field-of-view optical imaging system is provided for obtaining two images of a scene, each image having a different field of view. The dual field-of-view optical imaging system includes a frontal dual focus lens, the dual focus lens having a central zone of focal length f1 producing a wide field-of-view image at a first focal plane and a peripheral zone of focal length f2 greater than f1 producing a narrow field-of-view image at a second focal plane; and a detector for detecting and acquiring the wide field-of-view image and the narrow field-of-view image, the detector being movable along an optical path for selective positioning at the first focal plane or the second focal plane.Type: GrantFiled: February 19, 2010Date of Patent: October 23, 2012Assignee: Thales Canada Inc.Inventors: Hubert Caron, Monique Gauthier, legal representative

Patent number: 7115870Abstract: A driver vision enhancing system having a variable field of regard and a method of controlling the field of regard of a driver vision enhancing system. The system includes a housing, a movable sensor assembly located within the housing, a radiation detector connected to one end of the sensor assembly, and an actuator connected to the housing and able to contact the sensor assembly to move the sensor assembly in the housing and thereby move the radiation detector. The method includes moving a radiation detector as part of a driver vision enhancing system in a vertical direction within an image plane of the driver vision enhancing system.Type: GrantFiled: March 22, 2004Date of Patent: October 3, 2006Assignee: Thales Canada Inc.Inventors: Hubert Caron, Leslie Wrobel, Branislav Kovacevic

Patent number: 6521892Abstract: A thermal imager system for use in a vehicle utilizes an uncooled microbolometer detector array (19), optics (13) for conducting scene radiation to the array within a sensor module (12) which is separate from an image processing and display unit (39), to provide a small, direct view sensor module (12) that may be oriented for forward viewing. The sensor module (12) is mounted external to the vehicle and the image processing and display unit (39) is mounted internal to the vehicle, and the two are connected by a noise immune bidirectional digital communication path or harness (37). The optics (13) consist exclusively of refractive optical components (14, 16) providing a straight line radiation path from the scene to the array (19).Type: GrantFiled: February 10, 1999Date of Patent: February 18, 2003Assignees: Thomson-CSF Optronics Canada Inc., Thomson-CSF Optronique Canada Inc.Inventors: Michael Emanuel, Branislav Kovacevic, Marcela Faina-Cherkaoui, Hubert Caron, Leslie Wrobel

Patent number: 4753111Abstract: A fluid flow meter using a pair of temperature-variable resistance elements as detectors. Both elements are exposed to the fluid flow and supplied with a series of current pulses. The pulses supplied to one element, the reference element, are of very short duration so as to have no appreciable heating effect; the pulses supplied to the other element are of longer duration and are controlled so as to maintain this element at a fixed temperature differential above the other element, which remains at fluid temperature. The pulse width of the longer duration pulses is a measure of the flow rate of the fluid. Since the relationship between heat dissipated in the element and fluid flow varies with fluid temperature, the voltage pulses across the reference element are used as a measure of fluid temperature to compensate for this variation in calculating the exact fluid flow rate.Type: GrantFiled: November 19, 1986Date of Patent: June 28, 1988Assignee: Allied-Signal Inc.Inventors: Hubert Caron, Dimitri Petrov
