A semiconductor device has a substrate having a plurality of conductive pads formed thereon. One embodiment of the invention uses a microprocessor to preferably monitor and control the pressure, temperature and gas flow within a sealable enclosure to effectively control the carbonation of fruits and vegetables. The tuning frequency is corrected by the voltage divider circuit. The seat in one form is a double seat, in that it comprises a convertible seat and a fixed seat immediately next to each other. The selective optical filter is a moldable polymer filter that has three dyes therein to produce sharp notch filtering ranges at about 530 nm, 700 nm and 1060 nm and a fourth color balance dye therein to adjust the overall color of the filter making it more pleasing and desirable to the wearer.
