Patent number: 8705621Abstract: 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.Type: GrantFiled: February 14, 2011Date of Patent: April 22, 2014Assignee: Unisearch LimitedInventor: David Taubman

Patent number: 7176066Abstract: 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.Type: GrantFiled: May 19, 2005Date of Patent: February 13, 2007Assignee: Unisearch LimitedInventors: Rolf Brenner, Tilo Marcus Buehler, Robert Graham Clark, Andrew Steven Dzurak, Alexander Rudolf Hamilton, Nancy Ellen Lumpkin, Rita Paytricia McKinnon
