  • Patent number: 6934420
    Abstract: A method of image compression comprises the steps of recursively transforming a image using a Discrete Wavelet Transform. This creates a plurality of levels including at least a first level, multiple intermediate levels, and a low-low pass subband of the last level. The transformed image at each level is quantized, and datapacking the quantized image is performed. The step of datapacking further includes, encoding of the first level using adaptive run length of zero cofficients; encoding of the intermediate levels using run-length coding of zero coefficients and a predetermined two-knob huffman table for non-zero coefficients and encoding of the low-low pass subband using a low frequency packing algorithm.

  • Patent number: 6488968
    Abstract: A method of enhancing phytoestrogen bioavailability and a method for supplementing the dietary needs of warm blooded animals comprising orally administering an effective amount of a dietary supplement composition comprising a phytoestrogen, a fiber and L-glutamine, and optionally N-acetyl-D-glucosamine, in admixture with a biologically acceptable inert carrier.

  • Patent number: 6389176
    Abstract: The present invention relates to an image/video enhancement system and method for transmission of the image/video. The system processes an image before transmission using a pre-processor and then de-processes it after transmission using a post-processor. The pre-processor increases the compression ratio of the compression scheme used by the transmission system without losing image quality. The post-processor restores the transmitted image to a high-quality image.

  • Patent number: 5623153
    Abstract: A reverse self-aligned field effect transistor having sub-quarter micrometer (<0.25 um) channel lengths, lightly doped source/drain, and shallow junction depths was achieved. The method for fabricating the FET includes a doped pad oxide layer that functions as both an etch stop layer and a diffusion source for the lightly doped drain. The doped pad oxide prevents the substrate from being etched when a channel opening for the gate electrode is etched in a source/drain polysilicon layer. The sub-quarter micrometer channel length was achieved by reducing the channel opening by sidewall spacer techniques. The shallow source/drain junctions out diffused from the polysilicon are about 0.10 to 0.15 um depth, and the lightly doped source/drain. Junctions are about 0.05 to 0.08 um depth.
