  • Publication number: 20190115004
    Abstract: A panel assembly is formed by a plurality of bonds between two sheet materials in a face to face relationship to form a preform. The plurality of bonds define a closed perimeter region between the two sheet materials and an open perimeter region between the two sheet materials. The preform may be formed into a predefined shape. Pressurized fluid is applied through an inlet into the open perimeter region to expand the preform. The pressurized fluid expands the open perimeter region such that the two sheet materials expand in an opposing direction, thereby defining an expanded open perimeter region. The closed perimeter region between the two sheet materials remains vacant of the pressurized fluid such that the closed perimeter region is not expanded. The expanded open perimeter region is filled with a filler material for improving a performance characteristic of the panel assembly, e.g., strength, sound absorption, or stiffness.

  • Patent number: 10260121
    Abstract: In a method for increasing steel impact toughness, the steel composition contains from about 5 wt % to about 10 wt % manganese and has a martensite finish temperature (Mf) below room temperature. The steel composition is exposed to hot forming to form a steel part. During hot forming, the steel composition is subjected to a heat treatment temperature above its fully austenite formed temperature, is transferred to a die, and while in the die, is simultaneously formed and quenched. In one example, quenching cools the steel composition to room temperature, and the steel part is removed from the die and reheated to a baking temperature ranging from about 120° C. to about 400° C. In another example, quenching is interrupted at an interruption temperature ranging from about 120° C. to about 400° C., and the steel composition is maintained at the interruption temperature for a predetermined time and then is cooled to room temperature.

  • Patent number: 10259170
    Abstract: A method for use in efficiently joining together multiple workpieces to inhibit establishment of weld material in unwanted areas. The method uses a hybrid shaping-and-energizing system having a shaping tool and an ultrasonic horn. The method positions the hybrid shaping-and-energizing system proximate a workpiece, uses the shaping tool to form at least one recess in the proximate workpiece, and applies weld energy to the proximate workpiece using the ultrasonic horn. The recess is formed and the weld energy applied such that molten workpiece material becomes disposed within the recess, thereby inhibiting formation of weld material in the unwanted areas.

  • Patent number: 10259451
    Abstract: Systems and methods are provided for mitigating motion sickness. When motion sickness is predicted, the motion sickness mitigation system alters vehicle performance, cabin conditions, and/or alerts the occupant to upcoming vehicle actions, to avoid or alleviate motion sickness. A controller includes a processor that receives an occupant profile and traffic information for an upcoming trip of the vehicle on a route. Using the occupant profile and the traffic information, the processor calculates whether the occupant will experience motion sickness when the vehicle travels on the route. A vehicle performance signal correlated to the calculation, is delivered by the processor to initiate motion sickness mitigation. The vehicle performance signal varies operation of a steering actuator, an acceleration actuator, and/or a brake actuator to implement the motion sickness mitigation.
