Title: Dispositif implantable d'assistance ventriculaire
Inventor: MILLER PHILLIP J
IPC: A61M60/896
Filed: 1999-12-15
Granted: 2008-11-25
Abstract: Cette invention concerne un dispositif d'assistance ventriculaire (DAV) implantable dont la petite taille permet d'optimiser les possibilités d'implantation. Le DAV comporte deux chambres de volume variable et un actionneur assurant le refoulement séquentiel du sang hors des chambres, et une sortie commune, l'ensemble fonctionnant comme une pompe volumétrique. Les chambres à volume variable peuvent être constituées par des poches souples. La pompe fonctionne sous un débit sensiblement constant, comme pendant la phase systolique du ventricule à assistance. La pompe fonctionne à une première fréquence pendant la systole et à une seconde fréquence plus faible pendant la diastole. La pompe DAV comprend une paire de bobinages logés dans un cadre et espacés l'un de l'autre de manière à produire un flux de bobine au travers d'une paire de pôles. Une plaque avec induit et aimant est disposée dans le cadre de telle sorte que l'induit se trouve entre les pôles et l'aimant entre les bobinages. Des entrefers sont définis entre l'induit et chacun des pôles. Le flux de bobine fait se déplacer l'induit dans l'entrefer. Le volume des chambres représente une fraction du volume ventriculaire, de l'ordre de 20 ml par exemple.

Title: High power rotary transformer with bus duct assembly
Inventor: WHITE MICHAEL WALTER
IPC: H02J3/34
Filed: 2002-03-21
Granted: 2012-01-03
Abstract: A rotary transformer has a bus duct assembly that extends through the hollow shaft of a rotary transformer from collector or slip rings positioned above a drive motor for-the rotary transformer to end windings of the rotor positioned most remote from the drive motor. By positioning the leads of the bus duct connection with the rotor end windings on the rotor end windings most remote form the drive motor, the shaft strength and integrity is not reduced due to the torque applied by the drive motor. Further, the shaft is formed from two coupled shaft sections and the bus duct assembly comprises two L shaped sections each positioned substantially within a corresponding shaft section. The bus duct sections are interconnected to complete the bus duct assembly making it simpler to remove the first or upper shaft section from the second or lower shaft section during field servicing. Further, the use of the two bus duct sections within the shaft coupled together simplifies assembly of each bus duct section within its corresponding shaft section.

Title: Compositions and methods for the treatment of tumors
Inventor: BODARY SARAH C
IPC: C12Q1/02
Filed: 2000-07-27
Granted: 2014-09-23
Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based upon the identification of an ADAM8 gene that is amplified in the genome of tumor cells. Such gene amplification is associated with the overexpression of the gene product as compared to normal cells of the same tissue type and contributes to tumorigenesis. Accordingly, the ADAM8 protein encoded by the amplified gene is a useful target for the diagnosis and/or treatment (including prevention) of certain cancers, and acts as a predictor of the prognosis of tumor treatment.

Abstract: A method for utilizing redundant color inks to improve image quality while minimizing any undesirable effects such as texture or graininess. The method comprises tessellating the available redundant color space as defined by the available redundant ink colorants into regions where the regions are arranged so as to minimize the range of luminance variation found within the regions. The result is perceived by the eye as less grainy in texture as well as much more pleasing to the eye.

Patent CA-2424067-C (CA)
Inventor: GUPTA ROHIT
IPC: H04L29/08
Filed: 2003-04-01
Granted: 2012-09-11
Abstract: A security infrastructure and methods are presented that inhibit the ability of a malicious node from disrupting the normal operations of a peer-to-peer network. The methods of the invention allow both secure and insecure identities to be used by nodes by making them self verifying. When necessary or opportunistic, ID ownership is validated by piggybacking the validation on existing messages. The probability of connecting initially to a malicious node is reduced by randomly selecting to which node to connect. Further, information from malicious nodes is identified and can be disregarded by maintaining information about prior communications that will require a future response. Denial of service attacks are inhibited by allowing the node to disregard requests when its resource utilization exceeds a predetermined limit. The ability for a malicious node to remove a valid node is reduced by requiring that revocation certificates be signed by the node to be removed.

Title: Self-tuning statistical resource allocation for multipoint network events
Inventor: BAXLEY WARREN EDWARD
IPC: H04M3/36
Filed: 2002-03-18
Granted: 2010-07-13
Abstract: A method for dynamically allocating MCU resources (900) during a multipoint network event such as a conference call. The method determines the number of MCU resources (900) to allocate for the start (910) of the multipoint network event and then at each of a plurality of modeling intervals during the multipoint event adjusts (930) the number of allocated MCU resources based upon actual inbound users (940). Self-tuning (100) of the allocation of MCU  resources for multipoint events occurs in advance of use by providing a look ahead allocation of resources based on what is likely to be needed in the future for a conferencing event. The number of multipoint events (1020) occurring within a tuning interval are are counted (1010). The number of MCU  resources actually utilized during each multipoint event are accumulated (1040) and then a probability value is determined (1080) for future use of MCU  resources for an upcoming multipoint event.

Abstract: Human myelin basic protein (h-MBP) has a molecular weight of 18.5 KD and contains 170 amino acid residues. Synthetic peptides ranging in length from about 8 to 25 residues and covering the entire length of the protein have been produced. Antibodies to h-MBP (anti-MBP) were found to be neutralized by the synthetic peptides, in vitro, which span the h-MBP from about amino acid residue 61 to about amino acid residue 106. The peptides, which cover both the amino (about residues 1 to 63) and carboxy (about residues 117 to 162) terminals of h-MBP did not neutralize purified anti-MBP. Intrathecal administration of peptide MBP75-95, either as a single dose, or as repeated injections for periods up to 10 weeks, produced complete binding- neutralization of free (F) anti-MBP with no change in bound (B) levels. A control peptide MBP35-58 had no effect on F or B anti-MBP levels. Intravenous administrati on of MBP75-95 resulted in significant decline of F and B CSF anti-MBP levels over a period of one month. Administration of MBP synthetic peptides to MS patien ts either intrathecally or intravenously did not have any adverse neurological effects and systemic complications did not occur. The MBP epitope for MS anti-MBP ha s been localized to an area between Pro85 and Pro96. The longer peptide Asp82 to Thr98 is more soluble and thus can be administered in a smaller dose.</ SDOAB>
