Abstract: A method of Sabbath mode in an air conditioning unit includes receiving, at a controller of the air conditioning unit, a temperature signal from a temperature sensor, while in the Sabbath mode. Then determining that the temperature signal is one of above or below a threshold value, while in the Sabbath mode. Followed by adjusting, with the controller of the air conditioning unit, operation of a compressor in the air conditioning unit, while in the Sabbath mode.

Abstract: This disclosure proposes to speed up computation time of a convolutional neural network (CNN) by leveraging information specific to a pre-defined region, such as a breast in mammography and tomosynthesis data. In an exemplary embodiment, a method for an image processing system is provided, comprising, generating an output of a trained convolutional neural network (CNN) of the image processing system based on an input image, including a pre-defined region of the input image as an additional input into at least one of a convolutional layer and a fully connected layer of the CNN to limit computations to input image data inside the pre-defined region; and storing the output and/or displaying the output on a display device.

Abstract: The invention relates to a method of repairing a blade (1) made of composite material, extending in a so-called axial direction (X), the said blade (1) comprising a root (2) and a blade (3), the axial end of which opposite the root (2) comprises an area to be repaired, the said blade (3) comprising an intrados (4) surface and an extrados (5) surface.

Abstract: An injection mold for the manufacture of an axisymmetric part of composite material including a mandrel supporting a fibrous preform and including an annular wall, and a plurality of counter-mold angular sectors assembled on the mandrel and intended to close the mold and to compact the fibrous preform wound on the mandrel. Each angular sector includes an annular base intended to come into contact with the fibrous preform. The annular base extends between the first and second lateral edges in a circumferential direction, the first lateral edge of the annular base of an angular sector being in contact with a second lateral edge of the annular base of an adjacent angular sector.

Abstract: The invention relates to an impregnation mould for manufacturing a turbine engine part, made of composite material, obtained from a preform made of a weave of fibres, said mould having first and second portions provided with respective recesses that define a cavity capable of receiving the preform, in which at least one injection means of the mould allows a resin to be injected in order to impregnate said preform, wherein said at least one injection means has a plurality of tubular injection needles, which are capable of extending from at least one of the first and second recesses to penetrate at least the weave of the preform in order to allow resin to be injected.

Abstract: An injection molding device for fabricating a part, the device including an injection mold, the mold being formed of a support and a countermold that are distinct and that define between them a mold cavity presenting a first shape; and at least one injection device for injecting a fluid material into the mold cavity; the device including deformation elements configured to modify the shape of the mold cavity into a second shape distinct from the first shape.

Abstract: A method of machining an attachment flange of an aircraft turbomachine case, the method also including a system to machine the two opposite surfaces of the flange, and including a shape follower machining module, this module being designed to follow the shape of the flange and including a first structure equipped with a first machining tool, and a second structure equipped with a second machining tool, the flange fitting between the structures such that its two opposite surfaces are machined by tools, the module also including shape follower elements carried by the structures; and a device to drive movement of the machining module along a circumferential direction of the flange.

Abstract: A self-sharpening knife used inside an agricultural machine to cut and mix balls of hay or other food destined for animals consumption. The knife comprises a generally triangular steel plate whose base is right or rounded. The base is provided with a series of teeth, each of the teeth includes a pastille made of a material harder than steel and self-sharpening. The pastilles end by a cutting edge having a contour which forms the cutting edge of a tooth. The width of a pastille exceeds that of the steel and ends in a point which becomes round over cuts because of wear. The pastilles wearing out less quickly than steel thus causing that over cuts the width of the pastilles will always exceed the width of the steel. The pastilles cut until all their length and width are worn. The material of the pastille can be carbide or diamond.

Abstract: A sun visor includes a screen slidably mounted over a shaft attachable to a vehicle. A guiding profile is mounted in the screen, and a slider is rotatably mounted over the shaft and housed inside the guiding profile such that the guiding profile can slide longitudinally over the slider to establish a slide on rod function for the sun visor. A detent spring clip is attached to the slider and engages elastically over the shaft of the sun visor such that upon rotation of the screen of the sun visor, it is possible to establish a shading position and an inoperative position for the sun visor. The detent spring clip includes an asymmetrical shape to fit to an asymmetrical core shape of the slider in a single position. The slider includes an asymmetrical external shape to fit to an asymmetrical internal shape of the guiding profile in a single position. The guiding profile includes an asymmetrical external shape to fit to an internal shape of the screen in a single position.
