Abstract: A keyboard may be provided that has keys overlapped by a touch sensor. The keyboard may have key sensor circuitry for monitoring switching in the keys for key press input. The keyboard may also have touch sensor circuitry such as capacitive touch sensor circuitry that monitors capacitive electrodes in the touch sensor for touch sensor input such as multitouch gesture input. The keyboard may include an outer layer of fabric that overlaps the keys. The fabric may have openings that are arranged to form alphanumeric characters. Light sources may emit light that passes through the openings and illuminates the alphanumeric characters. The touch sensor may have signal lines that are not visible through the openings. The signal lines may be transparent, may be covered by a diffuser, or may circumvent the openings so that they do not overlap.

Abstract: An inkjet printing system comprises an inkjet printer and an inkjet ink comprising water, a self-dispersing carbon black pigment, and a water soluble polymer containing carboxylate groups, wherein: the carbon black pigment comprises greater than 11 weight % volatile surface functional groups; and the ink also contains an organic base having a pKa>7.5 and an optional inorganic base in combined amounts sufficient to provide alkaline equivalents of at least 150% of the acid equivalents of the water soluble polymer; provided the equivalents of the organic base are greater than or equal to the equivalents of the inorganic base.

Abstract: This invention is related to an inkjet ink comprising water, a first self-dispersing pigment, and a second self-dispersing pigment, wherein said first self-dispersing pigment comprises a charged group bonded directly to the surface thereof, and said second self-dispersing pigment comprises a charged group bonded through a linking group to the surface thereof.

Abstract: This invention relates to packaged photographic film that is capable of being alternately processed, according to individual consumer choice, by either (1) a traditional wet-chemistry process with a developer solution followed by desilvering in one or more subsequent solutions to obtain a color negative film, or (2) a dry thermal process without the use of aqueous solutions in which a blocked developing agent located within the photographic element is thermally activated or unblocked, optionally followed by electronic scanning of the developed film without desilvering. This invention enables a single film stock to be developed in both a conventional deep tank process and in a dry thermal process.

Abstract: A radiation-sensitive high bromide {111} tabular grain emulsion is disclosed in which at least 90 percent of silver halide epitaxy of an isomorphic face centered cubic crystal lattice structure containing at least 1 mole percent iodide is deposited on the {111} major faces in the form of monocrystalline terraces. Each epitaxial terrace is grown from a nucleation site along an edge of a {111} major face inwardly, with terraces overlying less than 25 percent of the {111} major faces. Surprisingly, these emulsions exhibit higher photographic speeds than those produced by growing silver halide epitaxy outwardly as protrusions from the corners or edges of the tabular grains.
