Abstract: The present disclosure relates to a stator for an electric motor, comprising: a stator body forming a ring extending along an axis between a front end face and a rear end face the stator body including an outer peripheral face and an inner peripheral face provided with teeth the teeth defining, in pairs, a plurality of notches open towards the inside of the stator body; a plurality of conductor segments inserted at least partially into the notches of the stator body; wherein the stator body is provided with at least one internal cavity, the at least one internal cavity housing at least one sound-absorbing or structural damping element, the at least one sound-absorbing or structural damping element being able to attenuate the vibrations and/or mechanical and/or magnetic noises generated by the stator during its operation within the electric motor.

Abstract: Systems and methods are provided to generate marketing content insights. In one embodiment, a disclosed method includes receiving input data including one or more advertising assets and one or more metrics corresponding to the one or more advertising assets; using a computer vision model, identifying one or more constituent elements of the one or more advertising assets; appending the one or more constituent elements and/or descriptions of the one or more constituent elements to the input data to generate a structured data set; training a generative AI model using the structured data set; training a prediction model using the structured data set; based on the trained generative AI model and a prompt, generating an additional advertising asset not included in the one or more advertising assets; and based on the trained prediction model, generating at least one predicted metric of the additional advertising asset.

Abstract: An acoustic shield for a motor vehicle engine (2), including a first portion made of a plastic material, the first portion having an element for attaching the shield to a motor vehicle engine, a second portion made at least partially of a sound-absorbent material. The second portion is intended for being placed in contact with the engine, wherein the first portion covers the second portion so as to at least partially conceal it and wherein the first portion has a central opening acting as a housing for a third portion. The third portion is configured to absorb the impacts transmitted by the motor vehicle bonnet during a pedestrian impact.

Abstract: The invention concerns a device (1) for attenuating intake noise and radiated noise that comprises an internal gas delivery conduit (2) linked to a combustion engine, the conduit (2) having a peripheral wall (23) on at least one portion of which there is disposed at least one element porous to air (4), sound attenuation means comprising at least one tube (3) disposed in the delivery conduit, at least one peripheral chamber (5) being delimited inside the conduit (2) between the tube (3) and the peripheral wall (23) of the conduit (2), the tube (3) comprising at least one portion having an opening (30) allowing the inside of the tube (3) to communicate with the peripheral chamber (5).

Abstract: The invention relates to a method of manufacturing an air-intake duct (30) with induction noise and radiated noise attenuation that is intended to be connected to an internal combustion engine. The method comprises the steps of: —(a): providing a mould (1) comprising two moulding cavities (2), each cavity (2) having at least one groove (4) adapted for moulding a rib (32) and having at least two half-bores (5) adapted for moulding end sleeves (34-36), —(b): providing a core (8) adapted to be positioned between the cavities (2), for moulding an air-intake duct (30), —(c): positioning a tubular layer (9) of air-porous material on the core (8), —(d): positioning the core (8) with the tubular layer (9) between the moulding cavities (2), —(e): injecting a thermoplastic material into the, or each, groove (4) and into each half-bore (5) of each cavity (2), in order to overmould ribs (32) and end sleeves (34-36) onto the tubular layer (9) so as to form a duct (30).

Abstract: The invention relates to an acoustic attenuation device (1) for a turbocharger, or for a supercharger, arranged along an air intake line of a vehicle. The attenuation device (1) comprises a gas supply pipe (2) having a peripheral wall (21) and a diameter (d2), the pipe (2) comprising at least one annular chamber (3) defined by a diameter (d3) greater than the diameter (d2) of the pipe (2), the or each annular chamber (3) being sealed by a wall (5) comprising porous material that is positioned in the extension of the peripheral wall (21) of the pipe (2), according to a diameter (d5) substantially equal to the diameter of the pipe (2), in order to allow air to flow between the pipe (2) and the or each peripheral chamber (3).
