Abstract: One embodiment of the present invention provides several electromagnetic radiation reflectors within a volume that contains solid portions subject to movement relative to one another. At least a portion of the reflectors are positioned beneath one or more of the solid portions and move in response to movement of at least some of the solid portions. The volume is irradiated with electromagnetic radiation having one or more frequencies in a range from one kHz through one THz, and a reflection is detected of at least a portion of the electromagnetic radiation from each of the reflectors in response to this irradiation. Movement among the solid objects is evaluated from the reflection of each of the reflectors, which includes determining a spatial orientation of each one of the reflectors as a function of at least one of polarization selectivity and frequency selectivity.

Abstract: This invention describes the means to disassemble and reassemble structural wall components for the rapid assembly, disassembly, and reassembly of buildings and related structures. The system consists of a high-strength bar and coupler system that may or may not be pre- or post-tensioned to a hyper-rigid foundation system that is comprised of fixed or mutable attachment points. The resulting dismountable structural/foundation system can be used with a wide range of traditional and non-traditional pre-assembled and assembled-on-site construction materials for both structural and non-structural wall sections. The system facilitates building reuse and less environmentally intensive processes for both temporary and permanent facilities.
