A method for transitioning a target from a missile warning system to a fine tracking system in a directional countermeasures system includes capturing at least one image within a field of view of the missile warning system. Specifically, a TFT obtained by forming an oxide layer including the metal over a metal film; crystallizing the oxide layer by heat treatment; and performing delamination in a layer of the oxide layer or at both of the interface of the oxide layer is formed. A digital sampling cycle by the AD converter is set to be shorter than the transfer cycle. One of the side sections is configured to slide in a lateral direction of the bed so as to vary a width of the bed. Because the metal conduit accepts electrons from the cathode electrolyte ions on its outer surface and emits electrons from its inner surface to ions in the anode electrolyte circuit it is termed an Ionic Capacitor.
