Title: Method and system for currency conversion
Inventor: NEMZOW MARTIN A
IPC: G06Q40/00
Filed: 1999-03-30
Abstract: The present invention is a currency translation system (10) that provides fo r the dynamic translation of a first currency value into a target currency val ue for the purpose of aiding localization and globalization of financial transactions. The system (10) may be used as a standalone translation system  or it may be embedded in a larger application such as a financial analysis program, a spreadsheet, a compound or object-loaded document, dynamic Web pages and other dynamically-generated content, databases or stored procedure s, or a Web commerce program. The system (10) takes as input the starting currency (100), a target currency (100), and transaction rules (110). The system (10) maintains a database (20) of currency rates, currency histories,  conversion rules and currency representation data. Optimization (230) and backtracking (240) techniques are used to deal with partial rate information  and in order to find optimal valuations involving a chain of currency translations. The system (10) can produce a single result or a matrix of results from which the user can choose an optimal valuation. The system (10)  also provides for the formatting (330) of a numerical currency value into a presentation specific to the locale of the translation request.
Patent CA-2334316-A1 (CA)
Inventor: ZUKERMAN RACHEL B
IPC: A23L7/196
Filed: 2001-02-06
Abstract: The present invention relates to a process for preparing ready-to-eat, shaped rice products that are comprised of visible, fully-cooked rice grains joined to each other. If the products of the present invention are frozen and stored frozen, they can be reheated with any common kitchen heating appliance. Rice grains are first infused with a fluid until their centers become soft, fluid-infused and fully-cooked. Food particles can also be added to and dispersed with the rice grains. The hot rice grains (without being cooled) are then immediately formed into shaped units such as rice finger foods or rice grain shells with formers that do not shear or mash the soft cooked rice grains. The fully-cooked and fluid-infused shaped rice units are then heated in either a fat-fryer or hot-air oven until their texture firms enough for them to be hand-held.

Title: C-myc is activated by beta-catenin and tcf-4
Inventor: HE TONG-CHUAN
IPC: C12Q1/68
Filed: 1999-08-20
Abstract: The APC tumor suppressor protein binds to .beta.-catenin, a protein recently  shown to interact with Tcf/Lef transcription factors. Here, the gene encodin g a Tcf family member that is expressed in colonic epithelium (hTcf-4) was cloned and characterized. hTcf-4 transactivates transcription only when associated with .beta.-catenin. Nuclei of APC-/- colon carcinoma cells were found to contain a stable .beta.-catenin-hTCF-4 complex that was constitutively active, as measured by transcription of a Tcf reporter gene. Reintroduction of APC removed .beta.-catenin from hTcf4 and abrogated the transcriptional transactivation. Constitutive transcription of TCF target genes, caused by loss of APC function, may be a crucial event in the early transformation of colonic epithelium. It is also shown here that the product s of mutant APC genes found in colorectal tumors are defective in regulating .beta.-catenin/Tcf-4 transcriptional activation. Furthermore, colorectal tumors with intact APC genes were shown to contain subtle activating mutatio ns of .beta.-catenin that altered functionally significant phosphorylation site s. These results indicate that regulation of .beta.-catenin is critical to APC' s tumor suppressive effect and that this regulation can be circumvented by mutations in either APC or .beta.-catenin.

Abstract: Selon un procédé de modulation spatiale multi-niveau, qui met en oeuvre une technique faisant appel à une table de bits pondérés où un nombre binaire à n chiffres représente le niveau de gris recherché de chaque localisation de pixel dans un ensemble de pixels binaires, on change des nombres binaires représentatifs en valeurs étroitement adjacentes de manière à réduire l'inégalité entre les 1 et les 0. Ce procédé peut être appliqué à une trame unique, ce qui modifie quelque peu l'échelle des gris, ou bien il est possible de mettre en oeuvre un procédé multi-trame selon lequel on change au moins certains nombres binaires en valeurs différentes dans des trames différentes de manière à réduire l'inégalité entre les 1 et les 0 sur l'ensemble des trames, tout en conservant ou en se rapprochant de la valeur de l'échelle des gris sous forme de moyenne temporelle. Ces procédés s'avèrent particulièrement utiles pour conserver ou se rapprocher d'un équilibre en courant continu de l'ensemble des pixels dans des modulateurs à réseau spatial à cristaux liquides.

Title: Force resisting corrugated assembly
Inventor: OGILVIE MORGAN O JR
IPC: B65D19/34
Filed: 2000-03-17
Abstract: The present invention is a force resisting corrugated assembly (10), and can be constructed into a pallet or dunnage support made from corrugated paperboard that minimizes adverse environmental impact, occupies little space before it is configured, and effectively saves production, storage and transportation costs. The present corrugated paperboard assembly can be shipped and stored as either one or more die-cut and scored corrugated paperboard pieces, thereby eliminating excess volume, with the pieces being readily interconnectable to form a complete pallet or dunnage support assembly. Preferably, the paperboard of the present invention further has a low moisture vapor transmission rate (MVTR), excellent glueability and recyclability. The present invention incorporates a lower and upper frame member foldably constructed from corrugated paperboard blanks. Each frame member has ribs (350) having locking slots. The lower and upper frame member can differ in dimensions, but in a preferred form incorporate nearly identical elements, thus simplifying production of the blanks and the folding steps necessary to form the present corrugated structure. After foldably constructing each frame member, the upper frame member is rotated 90 degrees relative to the lower frame member, and placed upside down over the lower frame member. The ribs (350t) of the lower frame member lock into the locking slots of the ribs (350b) of the upper frame member, and the ribs of the upper frame member lock into the locking slots of the ribs of the lower frame member.
