Patent CA-2358473-A1 (CA)
Inventor: RUCHTI TIMOTHY L
IPC: C12M1/34
Filed: 2000-01-19
Abstract: Ce système intelligent, destiné à mesurer de manière non vulnérante des analytes sanguins, fonctionne selon un spectre d'absorbance des infrarouges proches d'un tissu de peau in vivo. Une architecture hiérarchique met en oeuvre un moteur de classification de motifs, afin d'adapter l'étalonnage aux propriétés structurelles et à l'état physiologique du sujet, en fonction du spectre d'absorbance. On utilise des information (a priori) relatives aux sources premières d'une variabilité d'échantillon pour établir des catégories générales de sujets. En appliquant des schémas d'étalonnage spécifiques des diverses catégories, on diminue l'interférence spectrale, ce qui permet d'obtenir une meilleure justesse de prédiction et des étalonnages moins fréquents. L'invention concerne deux règles de classification. La première règle suppose que les classes s'excluent mutuellement et applique des modèles spécifiques d'étalonnage aux diverses catégories de sujets. La seconde règle met en oeuvre une théorie d'ensembles fous pour mettre au point des modèles d'étalonnage et des prédictions d'analyte sanguin. Ainsi, chaque échantillon d'étalonnage peut éventuellement influencer plus d'un modèle d'étalonnage, en fonction de son appartenance à une classe. De même, les prédictions à partir de plus d'un étalonnage sont combinées par le biais d'une clarification, aux fins d'obtention de la prédiction finale de l'analyte sanguin.

Title: Corona wire tensioning mechanism
Inventor: BERTRAM GARY B
IPC: G03G15/02
Filed: 2001-10-11
Abstract: A wire tensioning mechanism for tensioning a wire having an end one and an end two in a machine in which the wire has a means for attachment on end two and is fixed to the machine at end one, comprises a slide block, and a spring.     The slide block is slidably mounted to the machine at end two of the wire, such that the slide block slides parallel to the wire. The slide block has a slot which is wider than the wire but narrower than the means for attachment, such that when the slide block is mounted on the machine, the wire end two can be slid into the slot such that pulling the slide block in the direction away from the wire forces the means for attachment against the slot, but does not allow the means for attachment to pass through. The slot is lined up with the wire such that when the wire is in tension, there are no side loads on the means for attachment.

Inventor: MIZRAH LEN L
IPC: G06Q40/00
Filed: 2001-10-23
Abstract: A system and method for private and secure financial transactions. The system and method comprise embedded into financial institutions (financial institution ) privacy and security layer architecture and the "clocked" authentication, authorization and accounting (AAA) method. The system and method enable legal financial account holders (financial account holder) to perform buy/sell or withdraw/deposit financial transactions (financial transaction ) without disclosing private personal information to the transaction counterparts, while preserving highly elevated and enhanced security and fraud protection as compared with conventional methods. Before financial transaction, financial account holder initiates an authentication session with financial institution back office (financial institution back office) by accessing its central processing unit (CPU) and data base (dB), configured in the embedded privacy and security layer (EPSL) architecture with automated "clocked" AAA sessions by using dedicated communication lines. The authentication session is interactive, transaction specific and followed by either financial transaction deny or an alphanumeric signature generated for this specific financial transaction. Then financial account holder submits his/her request to a transaction counterpart along with the EPSL account number and the alphanumeric signature, generated by financial institution EPSL during previous authentication session. The transaction counterpart adds up additional or more refined financial transaction specific information and requests an authorization session with financial institution back office where the EPSL  account, CPU and dB are residing. The accounting session starts at the end of the authentication session and finishes along with the authorization session while being an essential part of them both. The system and method are particularly suited for use by banks, credit card companies and brokerage companies. Finally, the system and method are well adapted to the current and upcoming software, hardware, and electronic commerce technologies and can be easily implemented given an acceptable business trade off.
