Filed: 1996-07-12
Abstract: La présente invention concerne un procédé et un dispositif destinés à être utilisés dans un système numérique de fourniture de signaux vidéo. Une représentation numérique d'une oeuvre audiovisuelle telle qu'un fichier MPEG (104) est analysée pour produire un fichier d'étiquettes (106) qui comprend des renseignements sur chacune des trames dans l'oeuvre audiovisuelle. Pendant sa présentation, des données provenant de la représentation numérique sont envoyées d'une pompe vidéo (130) à un décodeur. Les opérations de recherche sont effectuées comme conséquence du fait que la pompe vidéo (130) est amenée à cesser de transmettre des données depuis la position à l'instant considéré dans la représentation numérique et à commencer à en transmettre depuis une nouvelle position dans cette représentation. Les renseignements se trouvant dans le fichier d'étiquettes (106) sont examinés pour déterminer la nouvelle position à partir de laquelle il faut commencer à transmettre des données. Pour garantir que le flux de données transmis par la pompe vidéo (130) maintienne la conformité avec le format vidéo applicable, des données de préfixe comprenant des informations d'en-tête appropriées sont transmises par cette pompe vidéo (130) avant la transmission de données à partir de la nouvelle position. L'avance rapide et lente et le rebobinage s'exécutent grâce à la sélection de trames vidéo sur la base des informations que renferme le fichier d'étiquettes (106) et de la vitesse de présentation désirée, et en produisant un flux de données contenant des données qui représentent les trames vidéo sélectionnées. Un éditeur vidéo produit un nouveau fichier vidéo à partir de fichiers vidéo existants. L'éditeur vidéo choisit des trames dans les fichiers vidéo existants, sur la base d'ordres de mise en forme et des informations contenues dans les fichiers d'étiquettes (106) des fichiers vidéo existants. Un fichier de vitesse de présentation, de position de départ, de position finale et de source peut être spécifié séparément pour chaque séquence que doit créer l'éditeur vidéo.
Patent CA-2199789-A1 (CA)
Title: Lithium cell recharging
Inventor: STEPHENSON ANDREW DAVID HAMILT
IPC: H02J7/10
Filed: 1997-03-12
Abstract: Excessive charging of the weaker cells in a battery of lithium cells, during potentiostatic charging, is prevented by providing each cell (S) with a bypass circuit (12) including a MOSFET (T). An integrated circuit (Y) monitors the cell voltage, and if the design voltage of the cell (S) is exceeded the circuit (Y) provides a signal to the gate of the MOSFET (T) so that part of the charging current (I) bypasses that cell (S), while most of the charging current flows through the cell (S).  The bypass current flows only while each of the other cells in the battery are coming up to the design voltage, so that little power is dissipated in the bypass circuit (12).  If the cells are balanced, so they accept charge equally, then the bypass circuit never carries current; if the cells are not balanced, they will be brought near to balance over a few charge/discharge cycles.

Abstract: La protéine basale de myéline humaine (h-MBP) possède un poids moléculaire de 18,5 KD et contient 170 restes d'acides aminés. Des peptides synthétiques ayant une longueur située entre 8 et 25 restes et couvrant la longueur entière de la protéine ont été produits. On a trouvé que des anticorps contre h-MBP (anti-MBP) sont neutralisés, in vitro, par les peptides synthétiques qui couvrent h-MBP du reste d'acide aminé 61 au reste d'acide aminé 106 environ. Les peptides qui couvrent à la fois les terminaisons amino (restes 1 à 63 environ) et carboxy (restes 117 à 162 environ) de h-MBP ne neutralisent pas anti-MBP purifié. L'administration intrathécale de peptide MBP75-95, soit en une dose unique, soit en injections répétées pendant des périodes allant jusqu'à dix semaines, a produit une neutralisation de liaison complète d'anti-MBP libre (F), sans changement des taux liés (B). Un peptide de contrôle MBP35-58 n'a pas eu d'effet sur les taux anti-MBP F et B. L'administration intraveineuse de MBP75-95 a entraîné une baisse importante des taux d'anti-MBP F et B dans le liquide céphalo-rachidien sur une période d'un mois. L'administration intrathécale ou intraveineuse de peptides synthétiques MBP à des patients atteints de sclérose en plaque n'a pas eu d'effets neurologiques néfastes et n'a pas entraîné de complications systémiques. L'épitope MBP de anti-MBP de la sclérose en plaque a été localisé dans une zone entre Pro85 et Pro96.

Title: Multimedia collaboration system with separate data network and a/v network controlled by information transmitting on the data network
Inventor: BURNS EMMETT R
IPC: H04N7/15
Filed: 1994-03-16
Abstract: A multimedia collaboration system that integrates separate real-time and asynchronous networks -- the former for real-time audio and video, and the latter for control signals and textual, graphical and other data -- in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environment. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mixing technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.
