Patent number: 11125795Abstract: The capacitive sensor can have a sensing body having two flat conductor elements positioned parallel to one another and held spaced apart from one another, and having a thickness normal to the flat conductor elements, the sensing body having at least one aperture formed across its thickness. The capacitive sensor can be used to measure an air gap between a stator and rotor of a rotary electric machine, and the presence of the apertures can facilitate ventilation and/or improve linearization process of capacitive sensor through redistribution of its current vs distance signal along the measuring range, thus potentially increasing signal to noise ratio where it is the challenging to do so.Type: GrantFiled: September 12, 2019Date of Patent: September 21, 2021Assignee: VIBROSYSTM INC.Inventors: Marius Cloutier, Mathieu Cloutier

Patent number: 10948843Abstract: Partial discharges in a high voltage electric machine can be monitored by a partial discharge monitor connected to the high voltage electric machine successively via a capacitive coupler and a connection cable. The connection cable can have a conductive element designed to self-destruct in the presence of electric current amplitude significantly exceeding expected current amplitudes from said partial discharges, and having diameter designed to avoid creation of additional partial discharges within the cable itself. The connection cable can be light enough to avoid adding excessive weight to the stator windings.Type: GrantFiled: June 11, 2018Date of Patent: March 16, 2021Assignee: VIBROSYSTM INC.Inventors: Marius Cloutier, Mathieu Cloutier

Patent number: 8277119Abstract: A temperature sensor, capable of operating in electromagnetic and/or electric environments such as electrical generators, motors and transformers and/or in environments where vibratory conditions are frequent or continuous, contains at least one light emitting optic fiber and one light receiving optic fiber and an electrically non-conductive dilatable object which variably occults the emitted light as the object's temperature varies. The light receiving optic fiber transmits light intensity and light intensity changes to an electronic device that may include a photometer and light-to-temperature computing equipment.Type: GrantFiled: October 29, 2007Date of Patent: October 2, 2012Assignee: VibroSystM, Inc.Inventors: Mathieu Cloutier, Jean Pronovost, Marius Cloutier

Publication number: 20070247613Abstract: An optical acceleration sensor includes a target having a reflective portion and a non-reflective portion. A conveyor causes light to be irradiated on the target. A receiver receives light from the target. An inertial mass is coupled to at least one of the conveyor and the receiver, wherein movement of the inertial mass relative to the target causes a change in intensity of an amount of light impinging on the portions to change an amount of light received at the receiver. The conveyor and the receiver may be optical fibers and may be disposed at least partially in an opaque conduit and held substantially parallel in a sensor head.Type: ApplicationFiled: November 7, 2006Publication date: October 25, 2007Inventors: Mathieu Cloutier, Jean Pronovost, Marius Cloutier

Patent number: 6878026Abstract: A device to be used for sitting at a table in a water filled area, such as a water pool. The device comprises an upper rigid, flat, floating body made of buoyant material and defining a table top, at least one lower seat member and a connecting member for rigidly attaching a bottom face of each lower seat member to an underface of the floating body at a level relative to the floating body such that a person can sit on the seat member while resting ones forearms or elbows on top of the floating body. The floating body and the seat member have surfaces and thicknesses enabling them to be self-stable in the water filled area while preventing a top surface of the floating body to be submerged when the person remains seated on the seat member.Type: GrantFiled: January 15, 2002Date of Patent: April 12, 2005Inventor: Mathieu Cloutier
