  • Patent number: 10205951
    Abstract: Embodiments of a method for incrementally coding and signaling motion information for a video compression system involving a motion adaptive transform and embedded coding of transformed video samples using a computer are disclosed herein. In one such embodiment, the method includes (a) storing computer-readable instructions in the computer which, when executed, produce an embedded motion field bit-stream, representing each, motion field in coarse to fine fashion and (b) storing computer-readable instructions in the computer which, when executed, interleave contributions from said embedded motion field bit-stream with successive contributions from said embedded coding of the transformed video samples.

  • Patent number: 8705621
    Abstract: A method and apparatus for producing a fully scalable compressed representation of video sequences, so that they may be transmitted over networks, such as the Internet, for example. Because the signal is scalable, users receiving the signal can obtain the signal at the appropriate resolution and quality that their system will handle or that they desire. A “motion compensated temporal wavelet transform” is implemented in order to enable compression of the video in a scalable fashion while still taking advantage of inter-frame redundancy in a manner which is sensitive to scene and camera motion. The motion compensated temporal wavelet transform is implemented by decomposing the video sequence into a set of temporal frequency bands and then applying a sequence of motion compensated lifting operations to alternately update an odd frame sub-sequence based upon an even sub-sequence and vice versa in a manner which is sensitive to motion.

  • Patent number: 7723024
    Abstract: This invention relates to a method of monitoring a fermentation process. In particular, the invention relates to a method of monitoring a fermentation process comprising the step of measuring the expression level of one or more zinc regulated nucleic acid molecules from a microorganism, preferably selected from the group consisting of Escherichia Bacillus, Cyanobacter, Streptomyces, Corynebacteria, Zymomonas, Saccharomyces, Zygosaccharomyces, and Schizosaccharomyces cells, present in the fermentation and comparing the expression level to a reference level of expression for the nucleic acid molecules, wherein the expression level is indicative of sub-optimal fermentation. Preferably the fermentation process is a beer brewing process.

  • Patent number: 7264673
    Abstract: The present invention provides a method of forming a shaped article having a matrix that contains sintered fly ash. The method comprises the step of blending fly ash together with water to produce a fly ash dough. The water is added in excess of that which is absorbed by the fly ash so that the dough contains free water so as to be in at least a partially fluid state. The method also comprises the steps of forming a green article in a desired shape from the fly ash dough, and removing at least a portion of the free water from the fly ash dough during and/or after forming of the green article. The green article is subsequently fired so that the shaped article is hardened by sintering its fly ash matrix. The present invention also provides a building element having a matrix of sintered fly ash.

  • Patent number: 7176066
    Abstract: A silicon substrate is coated with one or more layers of resist. First and second circuit patterns are exposed in sequence, where the second pattern crosses the first pattern. The patterned resist layers are developed to open holes which extend down to the substrate only where the patterns cross over each other. These holes provide a mask suitable for implanting single phosphorous ions in the substrate, for a solid state quantum computer. Further development of the resist layers provides a mask for the deposition of nanoelectronic circuits, such as single electron transistors, aligned to the phosphorous ions.
