    Abstract: A method for manufacturing a foam in a conduit comprises extruding a metal conduit. A metal foam powder is injected into a cavity of the metal conduit. The metal foam powder is activated to form a metal foam in the cavity of the metal conduit. A device for producing a foamed metal comprises an extruder that comprises one or more screws for extruding a metal through a die to form a conduit. The die comprises a plurality of ports for injecting a metal foam powder into a central hollow cavity or a wall cavity of the conduit. The device comprises a pressurizing section for increasing pressure on the metal foam powder and a thermal section for increasing the temperature of the metal foam powder to facilitate its expansion into a metal foam.

    Abstract: An automotive vehicle includes a closure frame defining an opening, and a closure for selectively covering the opening. The closure has a plurality of positions including a closed position, an open position, and an intermediate position between the closed position and the open position. The vehicle also includes an actuator configured to move the closure among the plurality of positions. The vehicle additionally includes an optical sensor disposed proximate the closure. The vehicle further includes a controller. The controller is configured to automatically control the actuator to move the closure from the closed position to the open position in response to a closure open request and no feature being detected by the optical sensor, and to automatically control the actuator to move the closure from the closed position to the intermediate position in response to a closure open request and a feature being detected by the optical sensor.

    Abstract: A method of forming a hole in a composite panel includes positioning a first fiber sheet on a layup table, where the layup table has a forming tool extending outward from a portion of the table, and the fiber sheet includes a plurality of fibers oriented along a first common direction. The method further includes extending the forming tool through the first fiber sheet such that a subset of the plurality of fibers are displaced about the forming tool: applying a resin to the sheet of fibers; pre-curing the resin to form a pre-preg part defining a hole about the forming tool; and removing the pre-preg part from the layup table.

    Abstract translation: 在复合面板中形成孔的方法包括将第一纤维片定位在铺层台上，其中铺层具有从工作台的一部分向外延伸的成形工具，并且纤维片包括多个沿着 第一个共同的方向。 该方法还包括使成形工具延伸穿过第一纤维片，使得多个纤维的子集围绕成形工具移位：将树脂施加到纤维片上; 预固化树脂以形成围绕成形工具限定孔的预浸料部分; 并从铺设桌子上取下预浸料。
