A brew-in-the-cup disposable beverage assembly includes a cup and a beverage pouch containing a premeasured charge of beverage material. The method first loads in the main library of the control panel, then checks and displays the PCMCIA module using the application interface of the control panel library. The calculation can use computer modeling to calculate a risk factor for growth of mold or a risk factor for growth of timber decay fungi. A second group of a plurality of heating elements are disposed separably from an inner wall surface of the heating furnace. This circuit allows for a low cost and low power CMOS implementation of an output signal formatter. The piston also has a distal portion smaller in transverse cross-sectional area than a proximal portion.
