Patent number: 7046800Abstract: Scalable Montgomery multiplication methods and apparatus are provided that are reconfigurable to perform Montgomery multiplication on operands having arbitrary data precision. The methods perform Montgomery multiplication by combining bit-wise and word-wise operations and exhibit pipelined and parallel operation. Apparatus include a control unit that directs bits of an operand to processing elements that receive words of a second operand and a modulus, and produce intermediate values of a Montgomery product. After an intermediate value of a word of a Montgomery product is obtained in a first processing element based on a selected bit of the first operand, the intermediate value is directed to a second processing element and is updated based on another selected bit of the first operand.Type: GrantFiled: July 21, 2000Date of Patent: May 16, 2006Assignee: State of Oregon Acting by and through the State Board of Higher Education on Behalf of Oregon State UniversityInventors: Alexandre F.

Patent number: 6958401Abstract: A method for making epothilones and epothilone analogs is described, as are novel compounds made by the method. One embodiment of the method was used to synthesize epothilone B by a convergent approach that entailed Wittig coupling of an ylide derived from phosphonium bromide with an aldehyde. The former was prepared from propargyl alcohol by a nine-step pathway which installed both trisubstituted double bonds with clean Z configuration. Macrolactonization of a resulting seco acid provided the following intermediate diene epothilone analog. Selective saturation of the 9,10-olefin and subsequent epoxidation provided epothilone B.Type: GrantFiled: January 27, 2003Date of Patent: October 25, 2005Assignee: The State of Oregon acting by and through the State Board of Higher Education on behalf of Oregon State UniversityInventors: James David White, Rich Garrett Carter, Kurt Frederick Sundermann

Patent number: 6948154Abstract: The invention includes a method for testing a spreadsheet cell. Du-associations are collected for the spreadsheet cell. The cell's execution trace is tracked. After the user validates the cell, the du-associations that participated in the execution trace are marked as executed. Du-associations for other cells that are affected by the testing a spreadsheet cell are similarly marking as exercised. If the user changes a cell's contents, the collected du-associations for the cell are discarded and the steps of collecting test elements, tracking execution traces, and marking are repeated. Cells that depend on the changed cell also repeat these steps. After the user marks a cell as validated, a validation symbol is shown on the cell. If the cell's validation status is later brought into question, the validation symbol can change or be removed entirely. The invention also includes a method for providing a user with feedback of the testedness of the spreadsheet cells.Type: GrantFiled: November 10, 1999Date of Patent: September 20, 2005Assignee: Oregon State UniversityInventors: Gregg Evan Rothermel, Margaret Myers Burnett, Lixin Li

Patent number: 6913877Abstract: Methods of detecting bioactive compounds include exposing compounds to one or more classes of chromatophores and measuring or sensing associated changes in one or more of the chromatophores. Representative methods permit identification and quantification of neurotransmitters, toxins, hormones, and chemical warfare agents with or without prior knowledge of the content of a sample. In some examples, chromatophores based on Betta fish are used. Cytosensor apparatus using such chromatophores include means for exposing chromatophores to a sample and optical detection systems for assessing changes in chromatophore optical properties. Compounds can be identified or quantified based on a red-green-blue or hue saturation-value representations of transmitted or reflected light or based on other characterizations of transmitted or reflected light.Type: GrantFiled: December 17, 2001Date of Patent: July 5, 2005Assignee: State of Oregon acting by and through the State Board of Higher Education on behalf of Oregon State UniversityInventors: Frank W.

Patent number: 6793831Abstract: A method for fabricating devices in a pre-assembled state comprising forming plural laminae, registering the laminae, and bonding the laminae one to another is described. The plural laminae contain the substructures and structures of the device. The substructures are coupled to structures and other substructures by fixture bridges in the pre-assembled state. The substructures of the device are dissociated by eliminating the fixture bridges. The plural laminae are registered and bonded to form the device either before or after the fixture bridges are eliminated. The fixture bridges can be eliminated in a variety of ways, including vaporization by electrical current, chemical dissolution, or thermochemical dissociation. One method to selectively bond the laminae together is by microprojection welding. Microprojection welding comprises forming laminae with projections that extend from at least one planar surface of the lamina.Type: GrantFiled: August 5, 1999Date of Patent: September 21, 2004Assignee: State of Oregon acting by and through the State Board of Higher Education on behalf of Oregon State UniversityInventors: Brian Kevin Paul, Richard Budd Peterson, Tyson Jedd Terhaar

Patent number: 6766509Abstract: The invention includes two methods for testing a spreadsheet region. Du-associations are collected for the spreadsheet region. In the Straightforward approach, du-associations are collected for each cell in the region. Each cell's execution trace is tracked. After the user validates a cell, the du-associations for the cell that participated in the execution trace are marked as executed. In the Region Representative approach, a region representative represents the region. Each cell's execution trace is tracked. After the user validates a cell, the du-associations for the region representative that participated in the execution trace for the validated cell are marked as executed. Du-associations for other cells that are affected by the testing of a spreadsheet region are similarly marked as covered. If the user changes a shared non-constant formula, the collected du-associations for the region are discarded and the steps of collecting test elements and tracking execution traces are repeated.Type: GrantFiled: December 27, 1999Date of Patent: July 20, 2004Assignee: Oregon State UniversityInventors: Andrei Ernstovich Sheretov, Margaret Myers Burnett, Gregg Evan Rothermel

Publication number: 20040109561Abstract: Multi-precision multiplication methods over GF(2m) include representing a first polynomial and a second polynomial as an array of n words. A recursive algorithm may be used to iteratively decompose the multiplication into a weighted sum of smaller subproducts. When the size of the smaller subproducts is less than or equal to a predetermined size, a nonrecursive algorithm may be used to complete the multiplication. The nonrecursive algorithm may be optimized to efficiently perform the bottom-end multiplication. For example, pairs of redundant subproducts can be identified and excluded from the nonrecursive algorithm. Moreover, subproducts having weights in a special form may be efficiently calculated by a process that involves storing and reusing intermediate calculations.Type: ApplicationFiled: August 6, 2003Publication date: June 10, 2004Applicants: The State of Oregon Acting by and through the State Board of Higher Education on Behalf of, Oregon State UniversityInventors: Cetin K.

Patent number: 6733784Abstract: An expanding tablet is described comprising a drug release controlling membrane material. After swallowing, the tablet hydrates and expands such that the membrane ruptures to directly expose some surfaces of the core tablet to hydrating and eroding liquids, thus generating in situ a tablet which is platform supported on non-exposed surfaces, and which releases active ingredient in approximately zero order fashion. More particularly, the dosage form is adapted for controlled release of various pharmaceuticals. A working embodiment of the tablet was a spray-coated tablet comprising a core having greater than 25% of an expandable material which expands upon exposure to an aqueous environment and at least one active ingredient, e.g., glipizide, and an outer rupturable coating surrounding the core comprising a rate release modifying membrane and a water-soluble modifier. A method for administering an active ingredient also is described.Type: GrantFiled: December 31, 2002Date of Patent: May 11, 2004Assignee: The State of Oregon acting by and through the State Board of Higher Education on behalf of Oregon State UniversityInventor: James W.
