A modular emergency shelter system includes a sleeping and storage module having a rectangular box-like structure with curved interior sidewalls defining a sleeping area, and exterior sidewalls extending to an opposing end defining a separate storage area. The plug includes a conductor organizing sled, which includes a plurality of channels for separating conductive wires. The carrier frequency offset of a second segment within the burst is corrected by a second segment carrier frequency offset correction value based on the first segment carrier frequency offset measurement value. A modulator modulates compressed data onto a carrier signal. The structured material connects at least two of the three-dimensional bodies. The automatic de-molding device utilizes at least one anchor member that is inserted into the mold and automatically secures the tread to the de-molding apparatus wherein the mold is mechanically removed from the mold.
