Abstract: Selon cette invention, une première image (ou autre motif) est représentée par un premier ensemble ordonné d'éléments A ayant chacun une valeur et un second motif est représenté par un second ensemble de ce type. Pour comparer ces deux motifs, il convient d'effectuer pour chacun d'une pluralité d'éléments x du premier ensemble ordonné, les étapes suivantes consistant : à sélectionner (103) à partir du premier ensemble ordonné une pluralité d'éléments x' à proximité de l'élément x considéré ; à sélectionner (102) un élément y du second ensemble ordonné et à comparer les éléments x' du premier ensemble ordonné avec des éléments y' du second ensemble ordonné (chacun de ces éléments ayant la même position par rapport à l'élément y' sélectionné du second ensemble ordonné de même que l'élément x' respectif de la pluralité d'éléments sélectionnés du premier ensemble ordonné a la même position par rapport à l'élément x considéré). La comparaison (106) consiste à comparer la valeur de chacun des éléments x' sélectionnés du premier ensemble à la valeur de l'élément y' correspondant de la pluralité d'éléments du second ensemble conformément à un critère de correspondance prédéterminé pour savoir si la pluralité d'éléments du premier ensemble ordonné correspond à la pluralité d'éléments du second ensemble ordonné. La comparaison est ensuite répétée avec une nouvelle sélection de la pluralité d'éléments x' du premier ensemble et/ou une nouvelle sélection d'un élément y du second ensemble ordonné générant une mesure V de similarité comme fonction du nombre de correspondances. A la suite d'une comparaison pour laquelle le résultat est une correspondance, la comparaison suivante est de préférence effectuée avec une nouvelle sélection de la pluralité d'éléments x' du premier ensemble et la même sélection d'un élément y du second ensemble.

Title: Appareil et procede d'introduction de bacteries contraintes benefiques dans le conduit vaginal
Inventor: LYNG ROBERT JOHN
IPC: A61K35/74
Filed: 2003-03-04
Abstract: L'invention concerne un traitement des infections vaginales qui n'entraîne pas la colonisation des bactéries introduites artificiellement, telles que les Lactobacilles. Les bactéries à effet bénéfique sont contenues dans l'enveloppe extérieure d'un insert vaginal qui empêche les bactéries d'être en contact avec les tissus vaginaux. Cette enveloppe extérieure permet aux sous-produits métaboliques générés par les bactéries à effet bénéfique de passer dans le conduit vaginal, ce qui permet de créer un environnement hostile pour les micro-organismes pathogènes. L'insert vaginal est placé par l'utilisatrice dans le conduit vaginal soit avec les doigts soit avec un instrument tel qu'un applicateur de tampon. Une fois la durée du traitement écoulée, l'utilisatrice enlève l'insert vaginal.

Abstract: A portable plastic film wrapping system comprises a push-cart having a vertical mast member mounted thereon, and a film roll carriage is vertically movable along the mast member. The film roll carriage is operatively connected to negator spring members by a film roll carriage lift cable, and, a holding pawl mechanism is adapted to be movable between ENGAGED and DISENGAGED positions with respect to the film roll carriage lift cable. When the holding pawl mechanism is moved to its DISENGAGED position, the negator spring members cause the film roll carriage to be vertically elevated, whereas when the holding pawl mechanism is disposed at its ENGAGED position, movement of the film roll carriage lift cable, and the film roll carriage, is effectively prevented. The film roll carriage can also be controllably moved in both upward and downward directions so as to achieve bottom-to-top, as well as top-to-bottom, wrapping modes of operation upon palletized loads.

Title: Method and apparatus for optimizing transmitter power efficiency
Inventor: JIAO QINGZHONG
IPC: H04B1/707
Filed: 2005-01-28
Abstract: The power efficiency of a transmitter is optimized through control of a selected aspect of the transmitter, for instance, a parameter of a power amplifier within the transmitter. The control of the aspect is based on a generated indication of desired average transmitted power. Based on this indication, a hardware path produces a first adjustment signal and a software path produces a second adjustment value, where the second adjustment value has been previously determined to correspond to the particular indication of desired average transmitted power through calibration. A difference between a first adjustment value, which is based on the first adjustment signal, and the second adjustment value is used to produce a correction signal, which is used to alter the first adjustment signal and produce a signal to control the selected aspect of the transmitter.

Title: Method of strengthening foreign epitope presentation by mhc class i by inhibiting tap activity
Inventor: IWAMOTO AIKICHI
IPC: A61P43/00
Filed: 2003-10-01
Abstract: A method of strengthening the presentation of a foreign epitope by MHC class I  by inhibiting TAP activity. A mammalian cell-infecting viral vector encoding both of a TAP inhibitor and epitope-binding .beta.2m is constructed and transferred into mammalian cells. Thus, endogenous MHC class I/peptide complexes are decreased by the TAP inhibitor and MHC class I/peptide complexes containing epitope-binding .beta.2m expressed from the vector are successfully presented on the cell surface at a high frequency. This method is useful in the vaccine therapy for infection and cancer.
