Abstract: A thin film transistor array fabricated on a polyimide substrate forms a backplane for an electronic display. The thin film transistor array incorporates gate electrodes, a gate insulating layer, semiconducting channel layers deposited on top of the gate insulating layer, a source electrode, a drain electrode and a contact layer beneath each of the source and drain electrodes and in contact with at least the channel layer. An insulating encapsulation layer is positioned on the channel layer. The layers are deposited onto the polyimide substrate using PECVD and etched using photolithography to form the backplane.

Abstract: A method to exterminate insects, urban environments, utilizing heat to kill the insects. Optimization of application of heat is shown. The intended environment hidden voids in urban structures.

Abstract: A method to exterminate insects, for example termites, in situ, whose situs is embodied within an urban structure. Gases that undergo no phase changes in the temperature range between ambient and lethal temperatures are directed on the structure to heat the structure itself to a temperature that is lethal to the insects, and maintaining that temperature long enough to kill the insects.
