Publication number: 20240111109Abstract: Systems and methods are provided for connection of an optical fiber to a substrate. The substrate may comprise waveguide(s), guide pin(s), and a substrate body. The guide pin(s) define a first and second end and comprise a capture feature proximate the second end. The substrate body comprises a receiving feature configured to receive and connect the first end of guide pin(s), and the second end of guide pin(s) extends outwardly from the substrate body. The system also comprises a connector configured to receive the optical fiber and including a receiver portion that has a locking feature and defines a recess configured to receive the guide pin(s). The capture feature is configured to engage with the locking feature. When the capture feature is engaged with the locking feature, the optical fiber is aligned with the optical waveguide(s) and restrained from movement relative to the substrate.Type: ApplicationFiled: October 18, 2023Publication date: April 4, 2024Inventors: Lars Martin Otfried Brusberg, Jason Roy Grenier, Jürgen Matthies

Publication number: 20220107051Abstract: The building of systems on breadboards such as optomechanical systems using reference stop assemblies is presented. Each reference stop assembly has a threaded base engageable with the breadboard to removably mount the reference stop assembly thereto, a support shaft connected to the threaded base and a reference ball. The reference ball is captively mounted to the support shaft and has a translational play in a plane perpendicular to the support shaft. The reference stop assembly also includes a clamping member mounted to the support shaft over the reference ball. The reference stop assembly is configured such that, when the reference stop assembly is mounted to said breadboard, the support shaft projects normally to the mounting surface of the breadboard and the clamping member cooperates with the breadboard so as to apply a clamping force to clamp the reference ball against a circular seat of a mounting hole on the breadboard.Type: ApplicationFiled: October 4, 2021Publication date: April 7, 2022Applicant: Institut National D'OptiqueInventors: Martin Grenier, Nichola Desnoyers, Frederic Lamontagne, Mathieu Legros

Patent number: 9486928Abstract: The present invention relates to a method and apparatus for limiting the contact force between a moving device and another object, using a parallel mechanism and torque limiters where the threshold force to activate the force limiting mechanism is not related to the configuration of the moving device or the location of the contact force relative to the activation point of the force limiting mechanism, and where the mechanism may be configured for one, two or three degrees of freedom. A counterbalance mechanism is also provided to counteract gravity load when the force limiting mechanism is configured for three degrees of freedom and responsive to contact forces including a vertical element. In particular, the invention relates to a method and apparatus for limiting the contact force between a moving robotic device and a contactable object.Type: GrantFiled: October 25, 2013Date of Patent: November 8, 2016Assignee: GM Global Technology Operations LLCInventors: Nicolas Lauzier, Clement Gosselin, Dalong Gao, Martin Grenier, Robin Stevenson

Patent number: 9031104Abstract: The laser mount arrangement can have a laser bar and a driver positioned adjacent to one another and secured against a connection face of a heat sink base. The heat sink base is connected to and forms a first electrical connection between the laser bar and the driver. A second electrical connection is also provided between the laser bar and the driver opposite the heat sink base, which can be in the form of a flexible metal sheet with a narrow upward fold. This arrangement can provide a low inductance path for the current.Type: GrantFiled: May 7, 2012Date of Patent: May 12, 2015Inventors: Jacques Godin, Martin Grenier, Louis Demers

Patent number: 5810043Abstract: A water chlorinator device for use in a water recirculating conduit system having a water pump connected therein. The chlorinator device comprises a housing having a chlorine-containing chamber vented to atmosphere. A perforated support member is provided for supporting one or more solid chlorine tablets. Projections support a lower one of the tablets elevated from a top surface of said support member. The water supply compartment is provided under the support member and is fed pressurized water from the conduit system downstream of the pump. The water entering the supply compartment exits through orifices formed in the support member whereby to form a turbulent, chlorine dissolving, water cushion above a top support surface of the support member. The water cushion is formed of a plurality of pressurized water jets to dissolve the lower one of the solid chlorine tablets to form chlorine-treated water.Type: GrantFiled: April 14, 1997Date of Patent: September 22, 1998Assignee: Magi-Eau Inc.Inventor: Martin Grenier
