Abstract: Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. An implant is delivered via transcatheter delivery into the LAA. The implant includes a conformable structure comprising a foam body and internal support. The support includes anchors that penetrate the foam body and anchor the implant to the walls of the LAA. The implant provides compliance such that it conforms to the native configuration of the LAA.

Abstract: A blade includes a root to be mounted in a slot of plural slots which opens out at an outer periphery of a rotor disk of a movable wheel of a low-pressure turbine of an aeronautical propulsion system, the rotor disk being centered on a longitudinal axis and the slots being circumferentially distributed about the longitudinal axis, the rotor disk further including blades circumferentially distributed at the outer periphery of the rotor disk, each blade being mounted in a corresponding slot, the root including a first platform which has a radially outer surface, a shroud having a second platform which has a radially inner surface, and an airfoil extending from the root to the shroud, the airfoil having a leading edge and a trailing edge. The shroud is formed of a material and has a defined difficulty.

At least one of the internal and external parts can include two independent rings, each having grooves or teeth, and the veil can have two annular branches connected respectively to the two rings.

Abstract: A thrust reverser for an aircraft propulsion assembly, including a fixed structure equipped with at least one cascade as well as a radially inner delimiting wall of a secondary vein, and a movable structure including at least one reverser cowling, the cascade being arranged, in the forward direct thrust position, in a housing of the reverser cowling, and, in the retracted thrust reversal position, the wall reveals a passage opening of the secondary vein towards the cascade, the thrust reverser also including at least one sealing membrane designed to deflect at least one portion of the secondary flow. A hook is provided for securing the membrane to a rear cascade support frame, and to the radially inner delimiting wall of the secondary vein.

Abstract: A thrust reverser for an aircraft propulsion assembly, including at least one sealing membrane designed to deflect at least one portion of the secondary flow towards a set of cascades when the movable structure of the reverser is in the retracted thrust reversal position, the reverser also including a first flexible hook connecting a first end of the membrane to the fixed structure of the reverser, a second hook connecting a second end of the membrane to the fixed structure or to the movable structure, the second hook being fixed to the radially inner delimiting wall of the secondary vein, or guided by an internal guide fixed to the same radially inner delimiting wall.

Abstract: Communication and charging assemblies for medical devices are disclosed herein. A communication and charging assembly in accordance with a particular embodiment includes a support element, with a communication antenna and a charging coil coupled to the support element. The charging coil can include wire loops having a plurality of wires and the support element can include a mounting surface shaped to match the charging coil and the communication antenna. In one embodiment, the communication and charging assembly are mounted in a header of an implantable signal generator.

Abstract: The present invention describes a Solid-Liquid-Solid hydrometallurgical process, optimized and independent of redox potential, to increase the solubilization of metals from ores and/or concentrates with a granulometry of less than 40 mm, by means of an initial stage called “Activation”; a second stage called “Dry autocatalytic transformation”; a third stage called “Washing and re-wetting”; and where the stages of dry autocatalytic transformation and washing and re-wetting, can be repeated in an alternating and repeated way.

Abstract: A scraper device for a disc of an agricultural machine includes: a first outer scraper element having a first scraper portion resting against the outer surface of the first disc and a first coupling portion coupled to a chassis; a first inner scraper element having a second scraper portion resting against the inner surface of the first disc and a second coupling portion coupled to the first coupling portion, the first inner scraper element swivel-mounted with respect to the first outer scraper element around a second rotation axis; and a resetting device connected to the second coupling portion causing a rotational movement of the first inner scraper element along the second rotation axis pressing the second scraper portion against the inner surface of the first disc and causing rotational movement of the first outer scraper element along the first rotation axis pressing the first scraper portion against the first disc.

Abstract: A medical device used for grasping a body tissue has a main body having a first arm rotatably connected to a second arm at a pivot point. The main body has a proximal end and a distal end. A handle portion and a locking portion are disposed at the proximal end of the main body. A gripping portion including at least one flexible member is disposed at a distal end of the main body. The at least one flexible member is one of a flexible silicone band and a first gel-filled silicone pad and a second gel-filled silicone pad.

Abstract: Techniques for determining situational interpretation information are discussed herein. A vehicle computing device associated with an autonomous vehicle can receive sensor data associated with an autonomous vehicle traversing an environment. The vehicle computing device can determine, based at least in part on the sensor data a planned trajectory usable to control the autonomous vehicle in the environment. The vehicle computing device can determine, based at least in part on the planned trajectory, situational information associated with the planned trajectory. The rationalization component can determine one or more indicators representing the situational information associated with the autonomous vehicle. A display device can display the one or more indicators.

Abstract: A wheel disc includes a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further includes an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a front surface and a rear surface such that the front surface has a relatively smooth profile and the rear surface has a plurality of concentric ring-shaped curvatures formed therein, thereby providing the transition portion with a variable thickness between the front and rear surfaces.

Abstract: A fuel supply circuit of an aircraft engine includes a centrifugal pump mechanically coupled with an engine shaft delivering mechanical power. The circuit further includes at least one electromagnetic pump including at least one stator delimiting an annular internal volume in which is present a rotor able to drive a fluid, a plurality of magnets annularly distributed on the rotor and at least a plurality of coils annularly distributed inside the stator face-to-face with the magnets. The rotor is connected to the engine shaft by a one-way clutching element.
