Patent number: 11959494Abstract: A pump assembly is presented including a motor housing holding an electric motor and a wet-end housing. The pump assembly also includes a heat transfer interface positioned between a front end of the motor housing and the wet-end housing. The heat transfer interface establishes a thermal conduction path between the motor housing and the wet-end housing so that, in use, a portion of heat generated by the motor is absorbed by the heat transfer interface and is dissipated in water circulating through the wet-end housing. In addition, or alternatively, another thermal conduction path may be established between the heat transfer interface and an electronic controller of the pump assembly so that heat generated by the controller is absorbed by the heat transfer interface and dissipated in water circulating through the wet-end housing.Type: GrantFiled: November 4, 2020Date of Patent: April 16, 2024Assignee: GECKO ALLIANCE GROUP INC.Inventors: Martin Pelletier, Benoit Laflamme, Philippe Lessard

Publication number: 20140116793Abstract: The hybrid vehicle can have a heat engine driving a first pair of wheels and an electric motor on another pair of wheels. The electric motor is selected to have a greater power than the heat engine, such as corresponding to the maximum power requirement of the vehicle, whereas the heat engine can have a power corresponding to a cruise power requirement of the vehicle. A generator is coupled to the heat engine and can be designed to have a generator capacity corresponding to the power of the heat engine. The electric motor can be used for propulsion during city driving conditions, and the heat engine can be used for propulsion during long range highway conditions, for instance. The design can be considered a power split through the road approach.Type: ApplicationFiled: June 5, 2012Publication date: May 1, 2014Applicant: PREVOST, UNE DIVISION DE GROUPE VOLVO CANADA INC.Inventors: Martin Pelletier, Alain Dulac, Christophe Lemarechal

Patent number: 6907164Abstract: An athermally packaged optical fiber device, such as a Bragg grating, is provided. The device includes a hollow structure, and a free and a threaded member projecting in the hollow structure from both ends. The optical fiber is mounted in tension inside the hollow structure through longitudinal fiber-receiving bores in both members, and has an anchor point affixed to each member with the grating therebetween. The anchor point of the threaded member is provided outside of the hollow structure, making the device more compact. The free and threaded members are rotatable together to adjust the resonant wavelength of the grating, and a nut may be provided to allow a fine-tuning. The hollow structure, free member and threaded member have a coefficient of thermal expansion selected so that they together compensate for the temperature dependency of the Bragg wavelength.Type: GrantFiled: September 12, 2001Date of Patent: June 14, 2005Assignee: Teraxion, Inc.Inventors: Richard L. Lachance, André Vo Van, Michel Morin, Martin Guy, Martin Pelletier

Patent number: 6130973Abstract: A method and an apparatus to photoinduce a grating or other type of modulated refractive index change in a photosensitive optical medium such as optical fiber. The resulting grating has a variable and controllable intensity profile and average value of the index change. The modulated refractive index change is photoimprinted in the medium in a series of writing steps, each comprising exposing a segment of the medium to a writing beam for a predetermined exposure time. To change the modulation intensity from step to step, the angle of incidence of the writing beam is dithered for an appropriate fraction of the exposure time at each step. This allows to control the amount of incident light on the medium for each step. If the exposure time is the same for each writing step, the average value of the index change may be kept constant avoiding undesired structure in the grating frequency response.Type: GrantFiled: March 26, 1998Date of Patent: October 10, 2000Assignee: Institut National D'OptiqueInventors: Jocelyn Lauzon, Martin Guy, Yves Painchaud, Martin Pelletier
