The nixel of the present invention can be in the form of a subpixel, a pixel, or a plurality thereof. The nixel can be made in a variety of shapes, and can be individually tested and sorted according to its mechanical and/or electrical attributes prior to being integrated into an ELD. A customized ELD can be made by selecting nixels of particular characteristics in accordance with ELD application and/or user specifications. Nixels can easily be arranged to form a variety of color patterns on an ELD. A nixel can include a lower electrode layer, a ceramic base layer, a first charge injection layer, a phosphor layer, a second charge injection layer and an upper electrode layer. Nixels can be positioned on a flexible display structure to produce a flexible and scalable ELD.

Abstract: An electroactive device incorporating the invention is configured from an electroactive ceramic hollow sphere having an inner surface, an outer surface, a wall thickness aspect and a radius aspect. Conductive electrodes are positioned on opposed surfaces of said sphere and conductors enable application of an electrical potential between the conductive electrodes to enable a field to be applied to said sphere that causes a dimension change in the radius aspect and thickness aspect thereof. In one embodiment the sphere has a d33 direction parallel to the thickness aspect, and d31 & d32 directions parallel to the sphere surfaces and in another embodiment the d33 direction is perpendicular to the thickness aspect, and d31 & d32 directions are respectively parallel and perpendicular to the sphere surfaces. The sphere is preferably supported by a rod that either passes throng one opening in the sphere or through two opposed openings. Further, the rod may include a pathway for other instrumentality's.

Abstract: A method for applying coatings to substrates using combustion chemical vapor deposition by mixing together a reagent and a carrier solution to form a reagent mixture, igniting the reagent mixture to create a flame, or flowing the reagent mixture through a plasma torch, in which the reagent is at least partially vaporized into a vapor phase, and contacting the vapor phase of the reagent to a substrate resulting in the deposition, at least in part from the vapor phase, of a coating of the reagent which can be controlled so as to have a preferred orientation on the substrate, and an apparatus to accomplish this method.

Abstract: A high intensity and high efficiency radiant gas burner (10) has a housing (8), a gas inlet (11) for receiving a combustible gas, a gas injection plate (13) for distributing the gas, a gas distribution chamber (16) for permitting the gas to expand, a porous ceramic layer (17) for receiving the gas from the gas distribution chamber (16), and a plurality of elongated flame support rods (23) situated over and spaced from a burner surface (17b) of the porous ceramic layer (17). When the gas is ignited, the flame transfers energy via convective heat transfer to the rods (23). When the rods (23) heat up, they radiate energy back towards the burner surface (17b) and also outwardly away from the burner surface (17b) so that radiation intensity and efficiency are optimized. A rod adjustment mechanism (84) may be disposed on the burner (10) for moving the rods (23) to thereby optimize radiation intensity and efficiency.

Abstract: A method of making a low voltage field device utilizing a preferentially etched unidirectionally solidified composite as the substrate. In the process, the composite is etched so that the electrically conducting rod-like or fiber phase protrudes above the matrix phase. The tip of the exposed fiber phase may be processed further to provide a rounded or needle-like geometry. Next, a layer of insulating material is deposited in a direction approximately parallel to the axes of the fibers to cause the formation of cone-like deposits of insulating material on the fiber tips which shadow the deposit on the matrix around the fibers and produce conical holes in the layer of insulating material about the fibers. Then, an electrically conductive film is deposited in approximately the same direction to produce on the insulating layer a cellular grid having openings corresponding in number and distribution to the fiber sites. Lastly, the cones of insulating material are removed from the fibers.
