Techniques for use in gamut mapping processes are presented, including a method for mapping cusp points using hue wheels to obtain a source relative hue angle, and interpolating a lightness value at the source point hue. Used is a photosensitive silane coupling agent having a secondary amino group protected by an o-nitrobenzyloxycarbonyl group. A container is coupled to the shaft of the ski pole. The grounding element provides an electrical pathway to ground electromagnetic emissions incident upon the EMI shield. In some embodiments of the invention data andor pilots are spread within each cluster using code division multiplexing.
