A composite of nanoclay and thermoplastic matrix polymer is disclosed, optionally containing a polyolefin elastomer and also optionally containing a dispersion agent for the nanoclay. A first drive circuit is coupled to the splitter and generates a drive signal for an audio driver from the low frequency signal. A switching device is used for switching the load limiting device. The improved detection technique allows rapid, reliable, and inexpensive measurements of arrayed platform output patterns. The comparison metric may be subjected to an adaptive filtering process, which strengthens the comparison metric in high frequency image regions to increase its impact on the gamut remapped colors, and weakens the comparison metric in low frequency areas, to weaken its impact on the gamut remapped colors. The pusher block is biased toward a front portion of the display rack, and the side walls of the display rack are configured to support a circular or elliptical product.
