Patent CA-2203131-A1 (CA)
Inventor: TSUDIK GENE
IPC: G06F21/34
Filed: 1994-10-27
Abstract: La communication entre les utilisateurs itinérants d'un réseau informatique fait l'objet d'une multitude de questions de sécurité: l'identification et le suivi d'un utilisateur en sont deux particulièrement importantes. L'invention porte sur un procédé et dispositif destinés à l'identification sécurisée d'un utilisateur itinérant et permettant d'assurer que ses déplacements ne peuvent pas être suivis. En d'autres termes, elle permet de procéder à l'identification sécurisée d'un utilisateur en toute discrétion. Elle consiste essentiellement à chiffrer l'identifiant utilisateur et/ou son mot de passe, et une indication de synchronisation, de préférence un intervalle de temps fixe, selon une fonction unidirectionnelle secrète, puis de transmettre le message chiffré, que l'on nomme "identifiant utilisateur dynamique", à "l'autorité locale" de l'utilisateur où celui-ci est enregistré. L'autorité locale est dotée de listes de tables de correspondances, calculées avant chaque intervalle de temps (ou autre mode de synchronisation sélectionné), des identifiants utilisateur dynamiques et de l'identité exacte correspondante de l'utilisateur. Elle peut donc savoir rapidement si le message chiffré qui a été transmis provient d'un utilisateur enregistré. D'autre part, un intrus ne peut ni détecter l'identité de l'utilisateur à partir des messages chiffrés ni suivre ses déplacements.

IPC: G01M17/02
Filed: 1997-10-15
Abstract: An apparatus and related methods for capturing a digital foot print image of a tire and for extrapolating load-deflection curves of the tire is presented. A frame carries a test pod that is coupled to a tire to perform various tests. In one application, a loading plate couples the tire to a transparent plate on the test pod where a camera captures a digital gray-scale image of the tire foot print. A processor converts the gray-scale image into a pressure map wherein each pixel of the digital image is correlated to a pressure value. In another application, the loading plate couples the tire to a sliding cover plate on the test pod, wherein the loading plate is incremented through a plurality of load values at predetermined inflation pressures. By using two inflation pressures, the processor extrapolates further load-deflection curves for the tire at other inflation pressures. The apparatus also provides a unique way for imparting camber on the tire during the above tests. The data collected from the foot print image and load-deflection curves may be used to analyze the construction, operation, noise generation characteristics and performance of the tire.

Title: Method for detecting nucleic acid sequences using competitive amplification
Inventor: MUSHAHWAR ISA K
IPC: C12Q1/68
Filed: 1996-06-03
Abstract: The present invention provides a method for quantitatively detecting the amount of a target nucleic acid sequence which may be present in a test sample. A test sample which may contain a target nucleic acid sequence comprising target sequences X and Y is contacted with two primer sets, the first set being specific for target X and the second set being specific for target Y. The test sample also is contacted at the same time with an internal standard sequence IS, which is substantially derived from a combination of the first and second target sequences, and its corresponding oligonucleotide primers. Haptens are associated with the oligonucleotide primer sets in such a way that amplified target sequence products X and Y are detected by capture on a solid phase to which anti-hapten capture reagents are attached. A signal ratio of (X + Y)/S is determined to quantitate the amount of the target nucleic acid sequence contained in the sample.

Filed: 1997-12-19
Abstract: An animal litter, particulary for cats, in which a gelatin solution is sprayed onto the granules and a dry adhesive is sprayed through the gelatin spray onto the granules. The gelatin solution provides enough dampening to adhere the adhesive particles to the clay particles, but because the gelatin sets quickly, it does not provide so much wetting as to activate the adhesive. Therefore the adhesive retains its adhesive properties and, together with the gelatin, causes the litter to clump when wetted by an animal.

Title: Imide oligomers and co-oligomers containing pendent phenylethynyl groups and polymers therefrom
Inventor: CONNELL JOHN W
IPC: B32B27/34
Filed: 1996-08-02
Abstract: Controlled molecular weight imide oligomers and co-oligomers containing pendent phenylethynyl groups (PEPIs) and endcapped with nonreactive or phenylethynyl groups have been prepared by the cyclodehydration of the precursor amide acid oligomers or co-oligomers containing pendent phenylethynyl groups and endcapped with nonreactive or phenylethynyl groups. The amine terminated amide acid oligomers or co-oligomers are prepared from the reaction of dianhydride(s) with an excess of diamine(s) and diamine containing pendent phenylethynyl groups and subsequently endcapped with a phenylethynyl phthalic anhydride or monofunctional anhydride. The anhydride terminated amide acid oligomers and co-oligomers are prepared from the reaction of diamine(s) and diamine containing pendent phenylethynyl group(s) with an excess of dianhydride(s) and subsequently endcapped with a phenylethynyl amine or monofunctional amine.  The polymerizations are carried out in polar aprotic solvents such as N-methyl-2-pyrrolidinone and N,N-dimethylacetamide under nitrogen at room temperature. The amide acid oligomers or co-oligomers are subsequently cyclodehydrated either thermally or chemically to the corresponding imide oligomers. The polymers and copolymers prepared from these materials exhibit a unique and unexpected combination of properties that includes higher glass transition temperatures after curing and higher retention of neat resin, adhesive and carbon fiber reinforced mechanical properties at temperatures up to 204 °C under wet conditions without sacrificing melt flow behavior and processability as compared to similar materials. These materials are useful as adhesives, coatings, films, moldings and composite matrices.
