Patent number: 7587660Abstract: Multiple-access codes are generated using an asymptotically optimal decoding algorithm, such as the Viterbi algorithm. A trellis may be constructed using a number of desired users, at least one code length, and a number of code-chip parameters. A fitness function is derived from a mathematical relationship between the multiple-access codes, and may include some measure of correlation of the codes. The multiple-access codes correspond to paths having optimal path metrics derived from the fitness function. Multiple iterations through the trellis may be performed to refine a selection of multiple-access codes.Type: GrantFiled: April 22, 2005Date of Patent: September 8, 2009Assignee: Kansas State University Research FoundationInventors: Justin S.

Patent number: 7585955Abstract: A process for separating a protein from a sample containing a mixture of proteins is disclosed. The process comprises forming an aqueous combination comprising the sample and an ion exchange material at a pH which is less than the pI of a first fraction of the proteins in the aqueous dispersion but greater than the pI of a second fraction of the proteins in the aqueous dispersion. The aqueous dispersion may then be intensely mixed, causing a fraction of the proteins in the combination to bind to the ion exchange material, and, optionally, centrifuged, causing the combination to stratify into a concentrated solids fraction and a supernatant, the supernatant containing the fraction of the proteins that did not bind to the ion exchange material. This process, including the steps of intense mixing and centrifugation, requires no expensive, specialized instrumentation, can be quickly performed, and is carried out in non-denaturing conditions, allowing for the separated proteins to be further studied.Type: GrantFiled: March 2, 2006Date of Patent: September 8, 2009Assignee: Florida State University Research Foundation, IncInventors: Qing-Xiang (Amy) Sang, Ziad Joseph Sahab

Patent number: 7583082Abstract: In a first step of image formation by MRI or the like, a gridding convolution is performed for each coil using a Kaiser-Bessel kernel, so that each coil channel now contains data on grid points. In the second step, another 2D convolution is performed on each of the gridded coil data sets in either k-space or image space, and all the convolutions are summed up to produce the composite k-space data set for the target coil. In the third step, the composite data set is then transformed to form an un-aliased image for that coil. In the fourth step, the un-aliased images for all the coils are combined using square-root-of-sum-of-squares to form the final reconstructed image.Type: GrantFiled: April 19, 2007Date of Patent: September 1, 2009Assignee: University of Virginia Patent FoundationInventors: Peng Hu, Craig H.
