Abstract: A transparent overlay input device includes a transparent non-conductive substrate, a plurality of transparent conductive electrode pairs and a transparent non-conductive cover. The plurality of transparent conductive electrode pairs are formed on the substrate and each form a proximity sensitive region and include a first electrode that receives an input signal and a second electrode that provides an output signal. The first and second electrodes are capacitively coupled and the capacitance of the electrode pair changes when a conductive member, e.g., a user's finger, is located near the electrode pair. The transparent non-conductive cover is formed on the substrate over the electrode pairs.

Abstract: An electromagnetic microactuator having a ferromagnetic substrate, preferably steel. A plurality of layers are deposited upon the substrate including an insulating layer, a seed layer and first and second photoresist layers. The first photoresist layer provides a coil well which defines the deposition location of a coil metal. The second photoresist layer provides central and peripheral core wells which define the deposition locations of a central core and a peripheral core, respectively. The second photoresist layer intersticially fills and protectively covers the coil.

Abstract: An active matrix transistor array substrate for a reconfigurable vacuum fluorescent display comprising a set of individually addressable pixels and an isolation grid surrounding each pixel of the set and isolating each pixel of the set from all other pixels of the set. The isolation grid is especially advantageous in a high density active matrix display for preventing one pixel that is switched off from inhibiting a neighboring pixel that is switched on from fully illuminating.

Abstract: A thin film field effect transistor has an island of polysilicon on the surface of a substrate, preferably of an insulating material. A layer of silicon dioxide is on the surface of the substrate and surrounds the polysilicon island. The silicon dioxide layer is of substantially uniform thickness and contacts the edge of the polysilicon island. A gate insulator layer, preferably of silicon dioxide, of substantially uniform thickness is on the surface of the polysilicon island. A conductive gate, preferably of doped polysilicon, is on the gate insulator layer and extends across a portion of the polysilicon island. The portions of the polysilicon island at opposite sides of the gate are doped to form the source and drain of the transistor. The transistor is formed by applying a layer of polysilicon on the surface of a substrate and applying a mask over the portion of the polysilicon layer which is to form the island.
