Abstract: An encoder implements a residual-free palette encoding mode in which a block of pixels is used to derive a palette table having a number of palette colors less than a number of pixel colors in the block of pixels, and to derive a color map representing each pixel of the block with a corresponding index number associated with a palette color that most closely matches the pixel's color. The calculations of residuals representing errors between the predicted palette colors and the actual pixel colors are omitted during the encoding process, thereby facilitating implementation of less complex palette mode encoder hardware at the expense of slight loss of color accuracy. Moreover, when multiple encoding modes are available, the encoder can employ the residual-free palette encoding mode when the rate-distortion cost or other cost of using this mode is determined to be the lowest cost of the plurality of encoding modes.

Abstract: The invention encompasses hydrogels, monomer precursors of the hydrogels, methods for the preparation thereof, and methods of use therefor. The linking of monomers can take place using non-radical, bioorthogonal reactions such as copper-free click-chemistry.

Abstract: A technique is provided for determining a loss risk assessment score for a vehicle trip. The technique includes, at a vehicle, a computing device receiving first information indicative of operation of the vehicle. The technique also includes, at the vehicle, the computing device receiving second information indicative of an environment at a particular location and time. The computing device correlates the first information and the second information to generate a data set. The technique also includes determining a score for the vehicle trip based at least in part upon the generated data set.

Abstract: Apparatus and methods for imaging and tracking of nano- and micro-scale objects with acceptable latency for relevant medical procedures, such as delivery of therapeutic payload or minimally invasive surgery are disclosed, including the capability to superimpose accurate anatomical data over a tracking image. Software applications are provided for data logging via a remote-control station; and software interface with remote motion control mechanism, controlling the motion of internal device.
