A method of encapsulating a device is disclosed. The first word line or the second word line is activated in response to the periodic signal. A plunger of smaller lateral dimensions is arranged concentrically and co-axially within the receptacle, and depends downwardly from the horizontally disposed support, and is of such a longitudinal dimension as to be spaced from the closed bottom of the receptacle so as to be submerged partially in the viscous fluid and is therefore free to move vertically. A foldable and portable frame with coverings is also disclosed. The electrode films include multilayer films with vertical bus bars and multilane films with horizontal bus bars.
