The upper and lower halves of a blow mold define a blow mold cavity when the halves are closed together. Thus, different implementations of the same architecture can be easily supported by modifying the parameter values. An inner panel is provided for dividing an interior of the airbag into a central first chamber and a second chamber around the first chamber. The set of two or more composite panels is attached to the bottom of the moment frame to provide a sub-floor of the building structure. In a second embodiment, an IHS includes a processor.
