  • Patent number: 12202071
    Abstract: The invention relates to a method and an apparatus for manufacturing a workpiece, specifically a rough diamond, into a product, specifically a brilliant. The method is performed by an apparatus providing a laser beam coupled into a pressurized fluid jet. The method comprises executing multiple cuts of the workpiece with the laser beam according to a predetermined cut-sequence to remove workpiece material with each completed cut. The method further comprises executing multiple rotations of the workpiece around the same axis of revolution according to a predetermined rotation-sequence. Thereby, a rotation is executed after a completed cut, and for executing a cut the laser beam is moved along a two-dimensional path.

  • Publication number: 20240186541
    Abstract: A method for humidifying an air supply of a fuel cell, an air supply circuit including an injection line, an intermediate line and an evacuation line. The method includes steps for recovering recycled air, in the evacuation line, and injecting recycled air into the injection line so as to mix it with ambient air from the environment. The method additionally includes increasing the ratio of recycled air in the injection line when a power setting of the cell reduces and if the power setting is lower than a predefined power threshold, and reducing the ratio of recycled air when the power setting increases and if the power setting remains lower than the predefined threshold.

    Abstract: The invention relates to a rolling handling machine (1) having an arm. The machine comprises an alert system comprising a memory in which are stored a plurality of alert rules for triggering at least one action from among transmitting data relating to the determined values of said parameters to a remote server (31); and emitting a visual, and/or sound, and/or vibration signal to alert the machine's driver. The triggering of an action occurs according to the speed of movement of the machine and the angular position of the arm. The invention also relates to an alert method and to a corresponding program product.

  • Patent number: 11708907
    Abstract: A method is provided for checking engagement and disengagement of a parking brake finger, which selectively blocks or blocks a shaft of the transmission. A motor-driven rotary selection plate is selectively controlled to butt against the transmission casing at the two ends of its travel, and is immobilized therebetween in a first functional engagement position and in a second functional disengagement position that correspond to the Park and non Park positions of the parking brake finger when the drive motor of the plate stops exerting torque thereon. The angular movements of the plate between its abutment positions are measured and incremented using a computer to determine whether the engagement position and disengagement position of the plate that is reached every time the drive motor is stopped corresponds to a command instruction given to the motor.

  • Patent number: 11519362
    Abstract: A turbofan has a nacelle delimiting a duct for a bypass flow and comprises a fixed structure comprising a guide vane support with guide vanes, a mobile cowl able to move in translation between an advanced position and a retracted position, arms, each one being mobile in rotation between a stowed position and a deployed position and comprising a distal end and a proximal end, a flexible screen, of which an exterior edge is attached to the guide vane support rearward of the guide vanes, and wherein the distal end of each arm is fixed along the interior edge, actuators to cause the mobile cowl to move, and an operating system which moves each arm. Replacing the reversal doors and their drive mechanisms with the flexible screen and the set of rotationally-mobile arms allows a reduction in weight.

  • Publication number: 20220207108
    Abstract: A method is disclosed for block processing two matrices stored in a same shared memory, one being stored by rows and the other being stored by columns, using a plurality of processing elements (PE), where each processing element is connected to the shared memory by a respective N-bit access and to a first adjacent processing element by a bidirectional N-bit point-to-point link. The method comprising the following steps carried out in one processor instruction cycle: receiving in the processing elements respective different N-bit segments of a same one of the two matrices by the respective memory accesses; and exchanging with the first adjacent processing element, by means of the point-to-point link, N-bit segments of a first of the two matrices which were received in the adjacent processing elements in a previous instruction cycle.
