A method including: forming a housing having at least one expandable portion, the forming including: expanding a covering to define a cavity; and expanding foam in the cavity in an expansion direction to expand the covering into a predetermined shape; and disposing one or more electronic components in the housing such that the one or more electronic components are capable of functioning after expansion of the at least one expandable portion. A method for dropping an object on to a surface from an altitude above the surface. The method including: providing an expandable member associated with the object; dropping the object from the altitude; expanding foam in a cavity associated with the expandable member to expand the expandable member prior to the object impacting the surface; and allowing the expandable member to contact the surface upon impact with the surface for at least partially absorbing an amount of the impact.
