An exterior trim for a motor vehicle has a body that forms a surface of the exterior trim. The body has an exterior surface and an interior surface, and defines a recess or cut-out. The body has a single undulating wall formed on the interior surface of the body substantially perpendicular to a plane defined by the body, and the single undulating wall at least partially surrounds the recess or cut-out. The exterior trim also includes a human-machine interface (HMI) device disposed at least partially within the recess or cut-out of the body. The HMI device may be used to externally control certain features of the motor vehicle.

A method is provided for producing a corrugated tube that has, at least in sections, first outer wall regions with a first external diameter and second outer wall regions with a second external diameter that alternate in a wave-shaped manner. The first external diameter is greater than the second external diameter. The corrugated tube is produced by a plastic vacuum/blow molding process in a plastic vacuum/blow mold with a corrugator (1). One or more openings are made in at least some of the first outer wall regions. The openings are made in at least some of the first outer wall regions of the corrugated tube during the plastic vacuum/blow molding process within the corrugator (1).

The invention is directed to a balanced process for extrusion of a plastic corrugated sheet or blanks, and subsequent converting of the blanks into plastic boxes. The process includes conveying the blanks to a plurality of forming stations for incrementally forming features on the blank needed for forming a box. The present process is performed at a slower speed than typical paper corrugated forming.

A method for manufacturing an acoustic panel by welding of at least two acoustic components made of thermoplastic material, a thermal gradient being applied on the acoustic components during the welding operation so as to apply a temperature higher than the glass transition or melting temperature of the material on the area to be welded and so as to apply a temperature lower than or equal to the geometric stabilization temperature of the material on the parts furthest from the area to be welded.

The disclosure proposes a fibreboard made of lignocellulose-containing fibres, in particular wood fibres and a binding agent for providing a fibreboard which enables to combine a high stability, on the one hand, and a comparatively small weight, on the other hand, and which can nevertheless be manufactured with a minor financial effort.

A method of forming a corrugated thermoplastic matrix composite sheet includes preheating a thermoplastic matrix composite sheet including a thermoplastic matrix and a reinforcement material to at least about a melting temperature of the thermoplastic matrix; preheating at least one of a pair of complementary corrugating tools to at least about a glass transition temperature of the thermoplastic matrix; compressing the preheated thermoplastic matrix composite sheet between the pair of complementary corrugating tools to form a corrugation in the thermoplastic matrix composite sheet; and holding the corrugation between the pair of complementary corrugating tools until a portion of the thermoplastic matrix composite sheet having the corrugation is below the melting temperature of the thermoplastic matrix to form the corrugated thermoplastic matrix composite sheet.

An endoprosthesis has an expanded state and a contracted state, the endoprosthesis includes a stent having an inner surface defining a lumen, having an outer surface, and defining a plurality of apertures through the outer surface, wherein the apertures are arranged in a micropattern; and a coating (e.g., polymeric coating) attached to the outer surface of the stent. The coating includes a base and a tissue engagement portion including a second surface facing outwardly from the stent, the tissue engagement portion including a structure that defines a plurality of holes extending inwardly from the second surface toward the base. The holes are arranged in a micropattern. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the structure applies a force that may reduce stent migration by creating an interlock between the vessel wall and the endoprosthesis.

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with a reinforcing stiffener. The corrugated pipe may include an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. In some embodiments, a stiffener may be positioned within the corrugation valleys. In other embodiments, a stiffener may be positioned within the corrugation crests.
