Abstract: System and method for providing control data for dynamically adjusting lighting and adjusting video pixel data for a display to substantially maintain image display quality while reducing power consumption. In accordance with one or more embodiments, image statistics, e.g., histogram data representing luma values corresponding to pixels for a video frame, are analyzed to determine whether the pixels represent one or more of a plurality of images which includes an image containing primarily natural imagery, an image containing primarily graphics imagery, and an image containing a combination of at least respective portions of natural and graphics imagery. Based on such analysis, control data are provided to enable light source brightness reduction by one of a plurality of percentages and pixel brightness increases, e.g.

Abstract: A method and systems are provided for creating an authentication of secure communications between a software video driver and a video display. A video driver transmitting digital video data deemed high-bandwidth digital content, to a display, performs authentication to determine if a secure connection has been established with a display. The video driver and the display both generate encryption keys that are compared to ensure that the display used is authorized for secure communications. A single stream of video data is encrypted using the secret keys. A first encryption key encrypts even-numbered pixels in the single stream of video data. A second encryption key encrypts odd-numbered pixels in the single stream of video data. The stream is split into two streams of data, which are transmitted to a display. The display decrypts each of the streams of encrypted video data and merges them to re-create the original stream of video data.

Abstract: A method and systems are provided for creating an authentication of secure communications between a software video driver and a video display. A video driver transmitting digital video data deemed high-bandwidth digital content, to a display, can perform authentication to determine if a secure connection has been established with a display. The video driver and the display both generate secret keys which are compared to ensure that the display used is authorized for secure communications. The video driver, communicating with a hardware video controller over a peripheral component interconnect (PCI) bus, can establish an encrypted link with the video driver. The video driver occasionally monitors the display to determine if a secure communications link is upheld. If the connection is determined at any time to be insecure, the video controller can alert the video driver, so that transmission of the video data can be terminated.

Abstract: A method for the preparation of new semi-crystalline, porous inorganic oxide compositions possessing uniform framework-confined mesopores in the range 2.0-10.0 nm. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N.degree.) and neutral inorganic oxide precursors (I.sup..quadrature.) at ambient reaction temperatures. The materials formed exhibit a disordered assembly of worm-like channels of regular diameter owing to the specific mechanism of self-assembly, producing highly stable materials and particles incorporating large numbers of the channels. This (N.degree. I.degree.) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.

Abstract: A method for the preparation of new quasi-crystalline, porous inorganic oxide materials possessing uniform framework-confined mesopores in the range 2.0-10.0 nm and large elementary particle size of more than 500.0 nm. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N.degree.) and neutral inorganic oxide precursors (I.sunburst.) at ambient reaction temperatures. The materials formed exhibit semi-ordered arrays of well defined pores owing to the specific mechanism of self-assembly, large pore wall thicknesses of at least 2.0 nm producing highly stable materials and large particle sizes incorporating large numbers of pores. This (N.degree. I.degree.) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures.
