Abstract: An audio description of a television program, i.e., a sound bite, is reproduced simultaneously with the display of the program at a television receiver. Specifically, the sound bite is embedded in a television signal that contains audio component and a video component. The television signal is transmitted to a plurality of television receivers and intercepted at one of the receivers. The video component is displayed on a monitor and the audio component is reproduced. On command the sound bite is reproduced instead of the audio component. An audio description of a television program, i.e., a sound bite, is also reproduced simultaneously with the display of a program listing of the program at a television receiver. Specifically, when the program listing is marked with an on-screen cursor, the sound bite is reproduced.

Abstract: A rapid process for making transparent tints that match the color and tinting strength of a standard tint. The process involves the use of a faster and more accurate shading technique that utilizes the light transmittance properties of the tints in the wet over the visible spectrum and calculates therefrom the amount of components required to bring the tint within an acceptable match to the standard.

Abstract: A pressurized-fluid-operated actuator has multiple piston surfaces for providing increased output force. The actuator includes a stationary cylinder that contains a movable cylinder having multiple inner chambers separated by stationary inner pistons. The inner chambers are in fluid communication with extension and retraction ports provided in the stationary cylinder wall. Introduction of pressurized fluid into one port causes the fluid pressure to act on “n” piston surface(s) to retract the movable cylinder. Introduction of pressurized fluid into the other port causes the fluid pressure to act on “n+1” piston surfaces to provide an increased output force without increasing the diameters of the cylinders and without increasing the pressure of the fluid.

Abstract: Flexible composite barrier structures are used to improve the resistance, to oxygen and moisture degradation, of an organic electronic device including at least one active layer comprising an organic material.

Abstract: An electrophoretic display comprises a fluid and a plurality of nanoparticles having diameters substantially less the wavelengths of visible light such that, when the nanoparticles are in a dispersed state and uniformly dispersed throughout the fluid, the fluid presents a first optical characteristic, but when the nanoparticles are in an aggregated state in which they are gathered into aggregates substantially larger than the individual nanoparticles, the fluid presents a second optical characteristic different from the first optical characteristic. The electrophoretic display further comprises at least one electrode arranged to apply an electric field to the nanoparticle-containing fluid and thereby move the nanoparticles between their dispersed and aggregated states. Various compound particles comprising multiple nanoparticles, alone or in combination with larger objects, and processes for the preparation of such compound particles, are also described.
