Abstract: A method and apparatus for enhancing a video image sent from a first terminal of a video-telephony system to a second terminal of the video-telephony system during a video telephony call. An image style is selected at the first terminal and a description of the image style is transmitted from the first terminal to the second terminal. A sequence of video images transmitted from the first terminal to the second terminal is modified by a style generator at the second terminal in accordance with description of the image style before being displayed at the second terminal. The first terminal includes a user interface that controls a style selector to produce the style description that defines the properties or the style such as a cropping region, a border style, an image filter, a background and an animation.

Abstract: A method and apparatus for object-of-interest image capture accomplishes the functions of capturing (120) a current image, determining (125) an object region of the object-of-interest in the current image, calculating (130) a contrast measurement of the object region, and identifying (135) the current image as having an optimized object region when an iteration measure meets a criterion. The current image is captured using a local exposure value determined from luminance readings of pixels within an object region of an object-of-interest of a previous image.

Abstract: A wet-etch composition for polyamic acids and partially cured polyamic acids comprising an aqueous solution having a major portion of water, a substituted hydrocarbon solvent and a non-ionic base that is strong enough to deprotonate the polyamic acid or a partially cured polyamic acid in a weight ratio of 0.1-49:49-0.1, with the proviso that the composition contains less than 1.0 percent ionic base. The present invention further provides a process for wet-etching polyamic acids or partially cured polyamic acids.

Abstract: A group of polyimides and copolyimides made from 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) or 2,2-bis(3,4-dicarboxyphenyl)propane dianhydride (IPAN) their acid or ester forms and selected aromatic diamines are disclosed which are useful for substrate coatings and interlevel dielectrics in on-chip and multi-chip package applications. In such applications these polymers exhibit lower dielectric constant, lower moisture uptake and reduced dielectric constant variation with temperature and humidity than existing polymers, yet they are both thermally stable at required processing temperatures and can form suitably adherent, pinhole-free coatings on electronic component substrates.

Thereafter, the electrically conductive particles, the size of which is sufficient so that the surfaces of the particles are coexistent with or extend beyond the surfaces of the membrane, may be added to the solution or, alternatively, the solution may be cast onto a casting surface and the particles added in a manner so as to ensure a uniform distribution of the particles throughout the solution. After evaporation of the solvent, the resulting thin film membrane may then be recovered and used in a gas separation apparatus or in a gas sensor apparatus.

Abstract: Novel high temperature thermoset terpolymers may be synthesized by reacting an alpha-substituted olefin, an alpha,beta-disubstituted olefin and a dual function monomer followed by cross-linking the resultant polymer with a low molecular weight multifunctional amine as the cross-linking agent in the presence of a catalyst. The resulting cross-linking agent is then cured at an elevated temperature to provide the desired terpolymer. This compound will possess desirable properties such as a low dielectric constant which renders it applicable for use as circuit board laminates.
