A cup holder tray having a plurality of cup pockets for receiving beverage cups therein, a finger spacing provided between two cup pockets, and a thumb-receiving surface above the finger spacing. The barrier drive ring is rotatable in opposite directions so as to drive the lens barrier member through the neutralizing spring between the open position and the closed position. The position of the pivot connection on the internal frame relative to the tilt actuator assembly can be selectively changed so that a single internal frame can be incorporated into mirrors of different sizes. The integrated circuit further includes a barrier located on the major surface for inhibiting a flow of the gas across the sensor element. Multiple photonic crystals are used to form a multiplexer and a demultiplexer.
