Patent number: 11828192Abstract: A lattice formed of entwined links in a cavity encased by the external skin of a blade and provided with parts of low mechanical strength referred to as breakable, which are capable of rupturing when sufficient loads are applied thereto during operation of the blade. This arrangement, which concentrates the ruptures at given locations, will leave the rest of the lattice intact and therefore will not hamper or will scarcely hamper its properties of heat evacuation by conduction or convection or pressure loss, if for example ventilation air passes through it.Type: GrantFiled: January 17, 2020Date of Patent: November 28, 2023Assignee: SAFRAN HELICOPTER ENGINESInventors: Laurence Vial, Sylvain Pierre Votie, Denis Daniel Jean Boisseleau

Patent number: 11384640Abstract: A turbine rotor blade including an airfoil that extends from a platform. The platform may include a first portion of a nominal platform contour substantially in accordance with Cartesian coordinate values of X?, Y?, and Z? as set forth in Table II. The Cartesian coordinate values of X?, Y?, and Z? are non-dimensional values from 0% to 100% convertible to dimensional distances by multiplying the Cartesian coordinate values of X?, Y?, and Z? by a height of the airfoil defined along a Z? axis. The X? and Y? values of the first portion are coordinate values that, when connected by smooth continuing arcs, define contour lines of the first portion of the nominal airfoil profile at each Z? coordinate value. The contour lines may be joined smoothly with one another to form the first portion.Type: GrantFiled: November 26, 2018Date of Patent: July 12, 2022Assignee: General Electric CompanyInventors: Jalindar Appa Walunj, Sylvain Pierre, Prem Venugopal

Patent number: 11277878Abstract: Two devices can be connected for communication by a wireless connection, where those devices will function as master and slave devices with respect to that connection. A slave device to a connection can perform changes to the connection on behalf of an application, subsystem, or other such source on either the slave device or a master device. These changes can include changes to connection parameter values, or can include state changes such as to perform a disconnect action. Enabling the slave device to perform these actions can help to bypass any restrictions that would otherwise prevent these actions being performed from a master device to the connection.Type: GrantFiled: May 5, 2020Date of Patent: March 15, 2022Assignee: FITBIT, INC.Inventors: Gilles Luc Jean Francois Boccon-Gibod, Andrew Scott Branscomb, Irvin Owens, Hsiao-Kai Wang, Sylvain Pierre Christophe Rebaud, Samuel Cordes Vaughn, Zachary Travis Willms

Patent number: 11181009Abstract: An assembly for a turbomachine including an annular channel designed to form a flow duct for a flow of gas between two turbine stages of the turbomachine. The channel is bounded by a radially inner annular wall and a radially outer annular wall. The walls are connected by hollow arms that extend radially, a support having a radially outer annular part that is located radially outside the outer annular wall of the annular channel, and a radially inner annular part that is located radially inside the inner annular wall of the annular channel. The outer and inner parts of the support are connected by connecting parts that extend radially and pass through one of the hollow arms of the annular channel. The connecting parts may be connected by a connecting partition having a frangible part that ruptures when the mechanical stresses in the connecting partition are above a threshold.Type: GrantFiled: February 28, 2019Date of Patent: November 23, 2021Assignee: Safran Helicopter EnginesInventors: Baptiste Hallouin, Alexandre Montpellaz, Sylvain Pierre Votie, Fabrice Iparaguirre, Yann Danis

Patent number: 10782861Abstract: In embodiments of objects alignment and distribution layout, an object layout interface includes objects displayed for selection and manipulation. A layout algorithm receives a reposition input for a selected object in the object layout interface, and determines a distribution layout and/or an alignment layout of the objects. The layout algorithm positions the selected object equidistant between at least two of the objects or at a distance from a closest one of the objects, the distance being an equivalent distance of a space between the at least two objects. The space between the objects is displayed as positive space that visually indicates the equidistance between the objects. Alternatively or in addition, the layout algorithm positions the selected object in alignment with multiple objects, and an alignment indication, such as an edge line and/or a distance measurement, is displayed for each instance of the selected object being aligned with the multiple objects.Type: GrantFiled: May 6, 2019Date of Patent: September 22, 2020Assignee: Adobe Inc.Inventors: Robert Christopher Travis, Tomas Krcha, Narciso Batacan Jaramillo, Talin Chris Wadsworth, Sylvain Pierre Galineau, Lawrence Hsu, Anirudh Sasikumar
