Granted: 2005-11-15
Abstract: Système de détermination du débit de données codées dans le récepteur (12) d'un système de communications à débit variable. Les données sont reçues sous forme de symboles regroupés dans des trames. Lorsque le débit de transmission des données est maximal, la trame est remplie de symboles. Lorsque le débit de transmission des données est inférieur au débit maximal, les symboles sont répétés dans la trame jusqu'à ce qu'elle soit remplie, ou bien les symboles sont espacés les uns des autres à l'intérieur d'une trame. Lorsque le débit de codage est égal au quart du débit maximal, par exemple, chacun des symboles compris dans la trame est répété quatre fois, ou bien la transmission des données est quatre fois plus rapide. Les trames en entrée sont décodées, par exemple par un décodeur (48), puis codées de nouveau, par exemple par un codeur (76), pour chaque débit de données possible. Un comparateur (par exemple 84) compare les symboles de nouveau codés avec les symboles reçus initialement, et un compteur (par exemple 100) compte le nombre d'erreurs de symbole. Chaque processus de décodage produit une indication de la qualité du processus de décodage, qui peut renfermer les résultats d'un contrôle de redondance cyclique (CRC) tel que le CRC (120), ou des mesures de qualité de Yamamoto. Le total des erreurs et l'indication de qualité comportent une mesure d'erreurs qui est transmise à un processeur, par exemple le microprocesseur (56). Le processeur analyse la mesure d'erreurs pour chaque débit de données et détermine le débit auquel les symboles en entrée ont le plus probablement été codés.

Abstract: An expansible balloon catheter (10, 15) has at least a first exterior surface (27) with a given coefficient of friction and a second exterior surface (32) with a greater coefficient of friction. In a compact form only the first exterior surface is exposed to produce a low coefficient of friction during transfer of the collapsed or unflated balloon to and across a lesion. When inflated, the second surface dominates the first surface and produces an increased coefficient of friction overall thereby to stabilize the balloon in the lesion.

Title: Improved routing method in a communications network
Inventor: BUSCHE MATTHEW T
IPC: H04L12/56
Filed: 1996-08-29
Granted: 1999-12-14
Abstract: A setup procedure employing distributed hop-by-hop routing reduces the number of signaling messages needed to establish a service (i.e., connection), thus enhancing network performance. A service is setup between an origination node and a destination node which are a part of a network of communication nodes interconnected by links. Each node maintains a topological database representing the network topology. Initially, a setup message for initiating the service is transmitted from the origination node to a neighboring node that serves as a local node. The topological database is then updated after the local node receives the setup message by eliminating links connected to a particular set of nodes. This set of nodes includes those nodes other than the local node that have previously transmitted a setup or failure message for the service. A shortest path is next determined from the local node to the destination node over the updated topology and another setup message is transmitted from the local node to a firstneighboring node in the shortest path. The previously-mentioned steps are repeated, beginning with the step of updating the topological database, where the neighboring node now serves as a subsequent local node. The steps are repeated until either a setup message reaches the destination node so that the service enters a connected state or no shortest path is found at the origination node, which indicates that the service has failed to enter a connected state.

Granted: 2002-12-17
Abstract: A wireless receiver having a first and second housings one of which contains a wireless signal transmission and receiving means.  The other housing preferably contains a power supply and possibly a battery back-up for use in the event of a cut in the power supply. The two housings are hinged together.  They are relatively movable between one position in which the two housings depend one from another so as to be mounted upon a vertical wall and another position in which the two housings are disposed one behind the other for supporting upon a horizontal surface.  Preferably, in the position for mounting upon a wall, the two housings provide rear planar surfaces which are coplanar and in the other position for mounting upon a horizontal surface the two housings provide planar support surfaces for supporting them upon the horizontal surface.  It is also preferable that these two support surfaces, when the housings are in a position for hanging vertically, lie closely adjacent, are parallel and confront each other so as to give the impression that the receiver is a single housing construction.  Similarly with the housings in the other relative positions other surfaces confront and lie parallel to each other also to give the single housing impression.

IPC: C09G1/02
Filed: 1997-02-28
Granted: 2001-07-24
Abstract: The invention relates to a waxless composition for cleaning and polishing acrylic and glass surfaces, which  consists  of  a  water-in-oil  emulsion  comprising water,  naphtha mineral  spirits,  an  abrasive,  an anti-static   agent,   a   thickening   agent,   dimethoxysilyl-dimethylamino-ethylaminopropyl  siloxane,  an  aminofunctional siloxane   capable   of   reacting   with   the dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane to form a cross-linked siloxane film and at least one emulsifying agent having hydrophilic functional groups.  The dimethoxysilyl-dimethylamino-ethylaminopropyl     siloxane and aminofunctional siloxane are sufficiently diluted to prevent reaction with one another in the emulsion so that when the composition is applied to an acrylic or glass surface  and  the  water  evaporates,  the  aminofunctional siloxane  reacts  with  the  dimethoxysilyl-dimethylamino-ethylaminopropyl  siloxane  to  form  the  cross-linked siloxane  film.  Such  a  film  imparts  to  the  surface  a uniform high gloss and water repellency, and efficiently protects  the  surface  against wear  and tear  caused by dust, cigarette smoke and fingerprints.

Title: A liquid discharging method accompanied by the displacement of a movable member, a liquid jet head for implementing such method, and a liquid jet apparatus for the implementation thereof
Inventor: ISHINAGA HIROYUKI
IPC: B41J2/175
Filed: 1997-07-04
Granted: 2003-03-18
Abstract: A liquid discharging method comprises the step of displacing the free end of the movable member following the creation of air bubble in the air bubble generating area.  For this method, the fulcrum of the movable member is positioned on the side different from liquid discharging side with respect to the displacement area for the free end of the movable member to be displaceable, and at the same time, the free end thereof is arranged to face the effective bubbling area positioned on the downstream side of the central portion of the length of the effective bubbling area that forms the bubble generating area in the direction of the movable member from the fulcrum to the free end thereof, and a part of the effective bubbling area positioned to face the free end of the movable member on the downstream side of the effective bubbling area is arranged to face the displacement area directly.          Thus, the initiation of the displacement of the free end of the movable member is effectuated quickly and reliably, and the pressure exerted by the air bubble creation is led to the discharge port side and the fulcrum side of the movable member sufficiently at the time of bubbling, and the development of air bubble that follows is directed to the discharge port side more reliably and efficiently.

Abstract: Décodeur (37) intégré à un récepteur de télévision (IRD) et comportant un récepteur (42) GPS qui vérifie si l'IRD est ou non dans un lieu autorisé et ne permet le débrouillage des signaux vidéo que si c'est le cas. Un système central de contrôle des accès (fig 1) distant du client/téléspectateur, muni d'un récepteur GPS (16) de haute qualité, émet certaines données GPS sur un moyen de transmission servant à l'émission des signaux vidéo à destination des clients. Les données GPS, qu'on dira ici indirectes, sont traitées par l'IRD plus simplement qu'auparavant. Lors de la production de certains signaux l'IRD introduit un délai pseudo-aléatoire (56) rendant beaucoup plus difficile la fraude par transmission de signaux trompeurs à l'IRD. Plusieurs des composants de l'IRD sont logés dans un boîtier commun fermé, circuit intégré ou une carte à puce, pour rendre plus difficile le bricolage des composants et les fraudes.

Granted: 2001-11-13
Abstract: Système intelligent de gestion mémoire de programme électronique de télévision et procédé qui supprime automatiquement les informations de moindre importance, stockées, relatives à une émission au moment même où le système a besoin d'espace libre en mémoire. Avant une mise à jour d'un programme d'émissions, le système exécute une opération de gestion interne de la mémoire à deux niveaux, opération au cours de laquelle le système balaye la mémoire à la recherche de données de programme obsolètes. Si, après ce balayage, il n'y a pas suffisamment d'espace disponible en mémoire pour la prochaine mise à jour, le système exécute une opération de "tri" de la mémoire à un second niveau, les données de programme, au cours de cette opération, étant classées automatiquement par ordre de priorité en fonction de règles prédéfinies permettant d'évaluer l'importance des informations communiquées au téléspectateur en fonction de l'horaire d'émission, du canal et d'autres variables concernant l'intérêt de l'émission. Le système supprime ensuite les données de programme par ordre d'importance, en commençant par les informations les moins importantes, et continue jusqu'à ce que l'espace disponible dans la mémoire suffise pour stocker la mise à jour des programmes.
