A topical, foamable composition is provided that includes at least one antifungal agent that is able to penetrate the upper layers of skin and is retained in or on an area to be treated for a prolonged period of time, and that has a residual non-volatile component content of less than 25%. A transfer member is disposed opposite to an image supporting member with the belt therebetween. Then, reservoir connectivity measures are calculated from the fluid travel time models and analyzed to determine a location for at least one well. When a comparator detects that the analog signal is lower than the charge voltage of the capacitor, a wakeup signal is output from the comparator to the microcomputer to cause the microcomputer to operate in the normal operation mode. The operating frequency of the first ring oscillator module, during a second mode, is a function of the first drive current.
