Abstract: A process for creating and an apparatus employing shaped orifices in a semiconductor substrate. A first layer of material is applied on the semiconductor substrate then a second layer of material is then applied upon the first layer of material. An orifice image is then transferred to the first layer of material and a fluid-well image is transferred to the second layer of material. That portion of the second layer of material where the orifice image is located is then developed along with that portion of the first layer of material where the fluid well is located to define an orifice in the substrate.

Abstract: A high-durability printhead for an ink cartridge printing system. The printhead includes a substrate having ink ejectors (e.g. resistors) thereon and an orifice plate positioned above the substrate. The orifice plate has a top surface, bottom surface, and a plurality of openings therethrough. The orifice plate is optimally produced from a non-metallic organic polymeric composition. To improve the durability, heat-stability, and ink resistance of the printhead, an intermediate layer manufactured from a thermoplastic polyimide is employed between the orifice plate and the ink ejector-containing substrate. This particular system generally improves the structural integrity of the printhead and provides longer cartridge life.

Abstract: A DCT based lossy compression method for compressing a digitized image composed of a matrix of image samples to provide a compressed image which satisfies a predefined bit budget. The digitized image is first sub-divided into blocks (e.g. of size 8.times.8 pixels). A discrete cosine transform (DCT) comprising a set of DCT coefficients is then derived for each block. A quantization table is selected from a set of quantization tables and, using the selected table, the coefficients of each DCT are quantized. A zero-value index, corresponding to the average number of zero value quantized DCT coefficients per DCT, is determined. A predicted zero-value index is calculated using said predefined bit budget and a quantization table selected from said set of tables using the determined index and the predicted index. Using that selected table, the unquantized coefficients of the DCTs are re-quantized and the requantized coefficients compressed using run-length encoding and Huffman encoding.

Abstract: An ophthalmic lens suited for extended-wear for periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. The lens has a balance of oxygen permeability and ion or water permeability, with the ion or water permeability being sufficient to provide good on-eye movement, such that a good tear exchange occurs between the lens and the eye. A preferred lens is a copolymerization product of a oxyperm macromer and an ionoperm monomer. The invention encompasses extended wear contact lenses, which include a core having oxygen transmission and ion transmission pathways extending from the inner surface to the outer surface.
