  • Patent number: 7863694
    Abstract: A thin film transistor having an improved gate dielectric layer is disclosed. The gate dielectric layer comprises a poly(hydroxyalkyl acrylate-co-acrylonitrile) based polymer. The resulting gate dielectric layer has a high dielectric constant and can be crosslinked. Higher gate dielectric layer thicknesses can be used to prevent current leakage while still having a large capacitance for low operating voltages. Methods for producing such gate dielectric layers and/or thin film transistors comprising the same are also disclosed.

  • Patent number: 7864346
    Abstract: A production and finishing system, particularly a printing and finishing system, for electronic management and control of a wide range of finishing processes characterized by input from multiple production operations and equipment that, depending upon the job, may be variably applied to work pieces that themselves are highly variable between different jobs. Particular emphasis is demonstrated in relation to printing and finishing operations for printed documents. The principles of the present invention, however, apply to such production and finishing systems as, without limitation, textile production (which may include printing, cutting, sewing, and finishing), packaging operations for various consumer and industrial products, and printed wiring board production, etc. The present invention is particularly applicable to many operations where processes for production of work pieces are managed separately from processes for finishing and packaging of such work pieces.

  • Patent number: 7863704
    Abstract: A high fill-factor photosensor array is formed comprising a P-layer, an I-layer, one or more semiconductor structures adjacent to the I-layer and each coupled to a N-layer, an electrically conductive electrode formed on top of the P-layer, and an additional semiconductor structure, adjacent to the N-layer and which is electrically connected to a voltage bias source. The bias voltage applied to the additional semiconductor structure charges the additional semiconductor structure, thereby creating a tunneling effect between the N-layer and the P-layer, wherein electrons leave the N-layer and reach the P-layer and the electrically conductive layer. The electrons then migrate and distribute uniformly throughout the electrically conductive layer, which ensures a uniform bias voltage across to the entire photosensor array. The biasing scheme in this invention allows to achieve mass production of photosensors without the use of wire bonding.

  • Patent number: 7864366
    Abstract: Document processing systems and methods are presented for transforming color image data from an input color space to output color space using space filling interpolation to mitigate loss of color information at the corners of color gamuts. An initial interpolation of the input color space pixel values for each pixel is performed to compute initial output color space pixel values, and these are converted into luminance-chrominance color space pixel values. An adjustment value ? is then computed according to the luminance-chrominance color space pixel values, and final output color space pixel values are computed according to the initial output color space pixel values and the adjustment value ?.

  • Patent number: 7865089
    Abstract: In a method for monitoring hardware devices of the hardware devices network to detect failures, past logged jobs are analyzed to determine a pattern of past usage of hardware devices by users of the hardware devices network. A failure of a hardware device is inferred based on a deviation in usage of the hardware devices from the pattern of past usage. In some embodiments, a state model is constructed that assigns one of two or more available operational states to each hardware device of the hardware devices network based on a recent load of jobs logged to the hardware device and a stored history of logged jobs indicative of typical loading of the hardware devices. One or more failing hardware devices are identified based on the assigned operational states.

  • Patent number: 7861997
    Abstract: A releasable deck mount used to tie printers to the deck of vessels includes a metal plate for welding to the vessel's deck that incorporates a profile of a clip that is connected to a strap and inserted into the deck mount for capture purposes. The plate is very low and minimizes any tripping hazard. A spring plate is attached to the top of the metal plate and a pin is secured to the spring plate and extends through a hole in the metal plate. The pin is designed to be movable and has a chamfer to allow insertion of the strapping clip. The clip is released from the deck mount by lifting the pin to allow the clip to be removed.

  • Patent number: 7864364
    Abstract: A color transformation method which accounts for colorant interactions includes establishing a plurality of tone reproduction curves (TRCs), for one or more of the color separations forming a digital image. Each TRC accounts for colorant interactions between a primary colorant with which the first color separation is to be rendered and at least one secondary colorant with which at least a second of the plurality of color separations is to be rendered. The TRCs include input values and their corresponding modified input values. In a given TRC, the input values of the second and optionally other color separations are fixed. For a pixel of the digital image having a given input values for the first and second color separation one or more of the TRCs are selected which bound the fixed input value for the second color separation and a modified input value is determined therefrom.
