Patent CA-2340630-A1 (CA)
Inventor: SAWYER FRANCOIS
IPC: H04W76/02
Filed: 1999-07-30
Abstract: L'invention concerne un système et un procédé pour déterminer la tarification d'un appel provenant d'une station mobile dans un réseau cellulaire de radiocommunications dans lequel un système publique fait fonctionner une macrocellule qui recouvre une microcellule faisant fonctionner un système privé (21). Le système privé indique s'il fonctionne normalement à un centre de commutation pour les services mobiles (MSC) faisant partie du système publique. Le MSC (23) envoie (40) une information de tarification à un centre de facturation (28). Elle comprend une indication de l'état du système privé (PSSI) qui permet de savoir si le système privé fonctionne normalement. L'information de tarification comprend également une identité de station mobile (MSID) et une identité de la cellule depuis laquelle l'appel a été établi (CELLID). Le centre de facturation (41) détermine (43), sur la base de CELLID, la cellule depuis laquelle l'appel a été établi et détermine (45), sur base de PSSI, si le système privé fonctionne normalement. On facture (47) l'appel selon un tarif préférentiel si l'on détermine que la station mobile appartient au système privé, que l'appel a été établi à partir d'une cellule publique et que le système privé ne fonctionne pas normalement.

Abstract: Méthode d'échange avec un utilisateur lorsqu'on établit les préférences d'un diffuseur de médias qui permet à l'utilisateur de configurer rapidement ses préférences à l'aide d'un affichage graphique. Le système de cotes de médias est converti en échelle numérique ou ordonné pour que les cotes soient disposées en ordre progressif de la moins inadmissible à la plus inadmissible. Une version consiste à attribuer une valeur numérique à chaque cote, puis de classer les cotes en fonction de la séquence numérique. Une fois les cotes ordonnées, elles sont affichées en mode graphique afin que l'utilisateur puisse sélectionner une position graphique correspondant à ses préférences, sans devoir nécessairement comprendre les associations sous-jacentes du système de cotes de médias.

Abstract: A locale identification triplet is provided and a related computer implemented method, computer system and computer program for making practical use of the locale identification triplet. The identifier includes a table identifier, locale version identifier a.nd a locale token. The locale token is the only mandatory identifier in the triplet and addresses the need to uniquely identify desired localization specifications through a concise unambiguous hexadecimal format.  The locale version identifier addresses the need to allow multiple variations of the locale specification defined for a given "root" locale, and the table identifier addresses the need to provide a mechanism to identify and distinguish a particular instance of a locale with regards to an environment (such as a system) or reference to an installation/application/user provided reference table.

Title: Inhibition of smooth muscle cell migration by heme oxygenase 1
Inventor: NABEL ELIZABETH G
IPC: A61K48/00
Filed: 1999-08-21
Abstract: The present method provides a method for inhibiting restenosis associated with mechanical injury of a blood vessel. Human heme oxygenase (I) (HO1) is directly administered at the site of injury. The present inventors have discovered that carbon monoxide generated by HO1 is involved in the molecular pathogenesis of vascular proliferative disorders. By using adenoviral-mediated expression of inducible heme oxygenase 1 in primary vascular smooth muscle cells (vsmc) in vivo, the present inventors demonstrate that in vivo expression of HO1 can be used to treat restenosis.

Title: Electroporation apparatus for control of temperature during the process
Inventor: HOFMANN GUNTER A
IPC: C12M3/00
Filed: 1999-09-27
Abstract: An electroporation method and apparatus generating and applying an electric field according to a user-specified pulsing and temperature profile scheme. The apparatus includes a cuvette holder with a Peltier device forming part o f the electrode structures that form part of the holder. Advantageously, one such pulse includes a low voltage pulse of a first duration, immediately followed by a high voltage of a second duration, immediately followed by a l ow voltage of a third duration. The low voltage electroporation field accumulat es molecules at the surface of a cell, the appropriately high voltage field creates an opening in the cell, and the final low voltage field moves the molecule into the cell. The molecules may be DNA, portions of DNA, chemical agents, the receiving cells may be eggs, platelets, human cells, red blood cells, mammalian cells, plant protoplasts, plant pollen, liposomes, bacteria , fungi, yeast, sperm, or other suitable cells. The molecules are placed in close proximity to the cells, either in the interstitial space in tissue surrounding the cells or in a fluid medium containing the cells.

Title: Expandible microparticle intracellular delivery system
Inventor: ROTHMAN JAMES E
IPC: A61K31/7088
Filed: 1999-09-14
Abstract: The present invention relates to methods and compositions for delivery of a compound, most preferably a polynucleotide, into the cytoplasm of a cell by means of a microparticle, fabricated from a pH-sensitive hydrogel in collaps ed phase, and having a size and physical characteristics compatible with uptake  via a clathrin-coated pit on the cell surface. The trigger pH at which the hydrogel expands is lower than the physiological pH of the extracellular environment, allowing the microparticle, which comprises the compound to be delivered, to maintain its compact size prior to cellular uptake, thereby providing the additional benefit of protecting the comprised compound from degradation. This protective feature is particularly beneficial in embodimen ts in which a polynucleotide or a peptide is being delivered. Following uptake via a clathrin-coated pit, the microparticle then enters the intracellular endocytic pathway, where it is subjected to a progressive decrease in pH. On ce the trigger pH for the hydrogel is reached, the microparticle increases its water content and expands, bursting its containing vesicle, and allowing its  comprised compound to enter the cytoplasm. According to the invention, microparticle expansion and drug release may be achieved by natural mechanis ms without requiringthe addition of exogenous compounds, or the application of electric fields, etc... Moreover, with regard to embodiments involving polynucleotides, the present invention provides a means for traversing the plasma membrane and delivering the polynucleotide into the cytoplasm; in conventional transfection methods the plasma membrane, as well as intracellular membranes as occur in endosomes or lysosomes, constitute a formidable barrier to entry.

Title: Reduced malto-oligosaccharides
Inventor: ANTRIM RICHARD L
IPC: C07H15/04
Filed: 2001-06-14
Abstract: Disclosed are a method for the reduction of an oligosaccharide mixture and an oligosaccharide mixture prepared thereby. In accordance with the disclosed invention, a mixture of oligosaccharides having a given DP profile is reduced to a DE of essentially zero by catalytically hydrogenating the mixture under reaction conditions sufficient to preserve the DP profile of the mixture, which reaction conditions typically include a reaction temperature ranging from about 50° C to about 150° C and a reaction pressure of at least about 1500 psi. Surprisingly, when the mixture is a malto-oligosaccharide mixture, the reduced mixture will have a superior color-fastness and thermal stability as compared to a similar unreduced mixture of malto-oligosaccharides, and also low reactivity towards nitrogen-containing species.

Title: Device, method and program for encoding/decoding of speech with function of encoding silent period
Inventor: ITO HIRONORI
IPC: G10L25/78
Filed: 2000-05-31
Abstract: A speech decoding device of the invention smoothes, in decoding speech signal in a voice-less period, RMS and filter coefficients which is discontinuously transmitted, and provides them to a synthesis filter. Thereby, it is capable of preventing discontinuous changing of the filter coefficient caused by the intermittent transmission of the filter coefficient. As a result, a quality of decoding can be improved. Also, to remove an effect, caused by the smoothing process, from the filter coefficients or the RMS which are transmitted in the past frames, a smoothing factor is adjusted not to perform smoothing while a certain time period (or a certain number of frames) from when a transition is made from a voice period from a voice-less period, or when a decoded feature parameter satisfies a predetermined condition.
