A technique for deriving timing information across wireless base stations is disclosed. Fiducials disposed along a longitudinal axis of a substrate are sensed and corresponding sensor signals are generated. The heater coil generates a magnetic flux, based on the applied current signal, for inductively heating the article. In some embodiments, fluidic media may be transferred from the vial to the reservoir by moving a handle operatively connected to a bias member for assisting with the transfer of fluidic media. An IDT may therefore be designed according to fundamental frequency internal dimension criteria but can operate at a multiple of the fundamental frequency, thereby providing much higher frequency operation than conventional SAW systems. The cold-storage appliance includes air transfer valves that mitigate the piston effect experienced when opening and closing a drawer, and bellows are attached to the drawer to maintain the vapor barrier.
