Abstract: A method of fabricating a curvilinear magnet includes forming at least one slot in a material billet. The slotted material billet is inserted into a mold having a curvilinear pocket. The mold is closed around the slotted material billet such that the slotted material billet conforms to the curvilinear pocket and forms a curvilinear billet. The curvilinear billet is arranged in a structure. The curvilinear billet arranged in the structure is then magnetized.

Abstract: Systems and methods for growth of multi-component single crystals are described. A first solution is flowed over a surface of a seed crystal coupled to a nozzle such that a plurality of first ions solvated in the first solution and a plurality of second ions in a second solution combine on the surface of the seed crystal to grow the single-crystal thereon. The first solution and the second solution are immiscible. A feed tank is fluidly coupled to the at least one nozzle and includes the first solution. In some aspects, the nozzle is configured to flow both the first solution and the second solution over the seed crystal.

Abstract: An ultrasonic tooling system for texturing a workpiece includes a horn having an end portion forming an interface with the surface of the workpiece. The end portion of the horn has a texture formed thereon. As a result of a high frequency ultrasonic vibration, the surface of the workpiece takes on a mirror image of the texture of the end portion of the horn. Alternately, the texture may be formed on an anvil and wherein, as a result of a lower frequency ultrasonic vibration, the surface of the workpiece corresponding to the anvil takes on a mirror image of the texture of the upper surface of the anvil.

Abstract: A lap belt pretensioner for a lap belt configured to secure an occupant of a vehicle seat includes a pyrotechnic device. The pyrotechnic device is configured to generate a force directed to tension the lap belt around the occupant and emit an exhaust gas including particulates at high pressure and high temperature as a byproduct of the generated force. The lap belt pretensioner also includes a housing configured to retain the pyrotechnic device and defining an exhaust passage configured to expel the exhaust gas from the lap belt pretensioner. The lap belt pretensioner additionally includes a shield arranged over the exhaust passage and configured to collect and/or deflect the emitted particulates and dissipate heat energy thereof. A vehicle having the vehicle seat mounted to the vehicle structure and employing the seatbelt system is also provided.

Abstract: A horn for an ultrasonic welding apparatus includes a body having an outer diameter surface and a convex welding tip having a first curved surface and a second curved surface. A peak curvature point is defined by the second curved surface. A base curvature point is defined at an intersection between the outer diameter surface and the first curved surface. An inner diameter is defined at an intersection between the first curved surface and the second curved surface.

Abstract: Methods of compression molding polymeric parts for improved impact resistance are provided. The components are particularly suitable for use in a vehicle or an automobile. The compression molded polymeric component comprises a central region or core comprising integrally formed foam, e.g., a foam core, that can sustain high impact load and does not lead to visible surface cracking or material cracking. The polymeric component may be a reinforced plastic composite (FRP). Such methods can produce lightweight, impact resistant, FRP components that may be used in various structural applications, including in automobiles.

Abstract: An assembly includes a sensor configured to obtain a data scan of a joint. A controller is operatively connected to the sensor. The controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for automated quality assessment of the joint. Execution of the instructions by the processor causes the controller to: obtain the data scan of the joint (via the sensor) and generate a first image based on the data scan. The first image is divided into a plurality of pixels having respective numeric values. The controller is programmed to identify a region of interest as the plurality of pixels from the first image with a respective numeric value greater than a threshold value (I0). The controller is programmed to assess joint quality based on a porosity factor (PF) determined at least partially from the data scan.
