A remote system for sensing a process fluid parameter comprises a cavity, a tuner and a signal coupler. The method includes patterning a substrate to form an active pattern, forming a gate pattern intersecting the active pattern, forming a gate spacer on a sidewall of the gate pattern, forming a growth-inhibiting layer covering an upper region of the gate pattern, and forming sourcedrain electrodes at opposite first and second sides of the gate pattern. Furthermore, a described implementation provides a mechanism for determining \u201coverlap\u201d and \u201cconflicts\u201d in policies. The cover is a single layer ionomer cover, and may be made from a blend of different grades of the ionomer. Such techniques provide control, including moving, sizing, and orientating, of one or more displayed window frames in which one or more images are displayed.
