A semiconductor package with a heat-dissipating structure and a method for making the same are proposed. N orthonormal basis functions are employed using coherent reception, resulting in a proportional increase in transmission rate with only a modest increase in bit-error ratio. The profiles can be adjusted by altering profiles of molar fractions of In and Al. The securement mechanism includes one or more isolation mechanisms for reducing or substantially eliminating transmission of potentially accuracy-affecting or otherwise damaging vibrations to the regulator and gauges. The mat also comprises means for lifting, including passages through which chains or cable may be threaded, lifting shackle assemblies or pear link assemblies. The media files corresponding to the selected previews are then transferred to the portable media player during a subsequent synchronization process.
