A white organic light-emitting diode includes a transparent electrode, a blue-complementary light-emitting layer, a translucent electrode, a blue light-emitting layer, and a non-transparent electrode. The press includes: an outer die; an inner die situated inside the outer die; a former rod opposing the inner and outer dies; and, a shear punch situated coaxially with the former rod. The seat can be installed on a corner post of the cart structure, manually rotated to level position around the cart’s corner, providing seating at either side, or back of the cart, and in stow position rests against cart structure. The receiver discards the reordered ATSC data or the normally ordered robust VSB data depending upon receiver type or user selection. Digital signals are amplitude encoded at levels related by powers of two so that no encoding ambiguity is created. The substrates are used in the manufacture of components for the interior of refrigerators and freezers, which include wire and glass shelving, plastic crisper baskets and other articles within the food storage area.
