A vector field including its local three-dimensional attribute is substantially visualized on a two-dimensional field of view in an intuitionally visible way. The impact-reduction box includes a roller frame subassembly and spring box subassemblies attached thereto on either side. A method for forming an interconnect structure includes etching to form an opening in the interlevel dielectric, the etching operation being terminated at or above the etch buffer layer. The tubular body is translatable in the radial position andor rotatable relative to a longitudinal centerline extending through the non-rigid coupling.
