Abstract: A system and method of inflating an airbag and trajectory control tube are disclosed. The system and method include detecting application of a force at at least one of a plurality of sensors, initiating an inflation system to cause inflation of the airbag and the trajectory control tube responsive to the detecting, inflating the trajectory control tube based on the initiating, inflating the airbag, and breaching the airbag and the trajectory control tube compartment. The system and method include guiding the airbag deployment trajectory via the trajectory control tube guides the airbag deployment trajectory. The system and method include the guiding occurs as the airbag begins to inflate, as the airbag inflates, after the airbag has inflated or before the airbag inflates.

Abstract: A system and method of inflating an airbag are disclosed. The system and method include detecting application of a force at at least one of a plurality of sensors, initiating an inflation system to cause inflation of the airbag and an airbag positioner responsive to the detecting, inflating the airbag positioner based on the initiating, inflating the airbag, and breaching a compartment initially housing at least one of the airbag and the airbag positioner. The system and method include inflating the airbag positioner to reposition an out-of-position occupant reducing the constraints on the design of the airbag and improving protection for the in-position occupant.

Abstract: A method includes: determining a design for a longitudinal piece of a particular length, wherein first and second ends of the longitudinal piece have dissimilar shapes; extruding a piece that is at least twice the particular length, wherein a profile throughout the extruded piece has the first end shape; hydroforming the extruded piece to generate an expanded portion between ends of the extruded piece, wherein the ends retain essentially the first end shape; and cutting through the expanded portion to obtain a piece wherein one end has the first end shape and another end has the second end shape.

Abstract: Methods, program products, and computer systems for estimating a stress of a toughened structural adhesive polymer are provided. One method comprises selecting a strain, a strain rate, a temperature, or a combination thereof at which the stress is to be estimated. A value of a strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the strain-hardening stress is dependent on the temperature and the strain. A value of a non-strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the non-strain-hardening stress is dependent on the strain, the strain rate, and the temperature. The value of the strain-hardening stress is added to the value of the non-strain-hardening stress to obtain an estimated total stress.
