Title: Wheelchair lift for automobile
Inventor: DYCK ISAAC
IPC: B60P1/00
Filed: 2003-07-30
Abstract: A wheelchair lift is attached to the frame underneath an automobile and includes a horizontal platform carried on a pair of parallel arms defining a platform support which is slidably received in a low profile hollow housing or container. The housing defines two end rails at right angles to the vehicle length on which the arms slide so that the arms can be moved to a cantilever position projecting from one side of the vehicle. The platform is mounted on each arm of the platform support by a pair of parallel levers for movement upwardly and downwardly from a lowered mounting position of the platform in which the wheelchair can enter onto the platform to a raised entry position in which the wheelchair can move from the platform onto the floor of the automobile. The levers are actuated by cylinders lying along the arms so that the whole of the platform and its support can be received into the housing for transport with the vehicle.
Patent CA-2437156-A1 (CA)
Inventor: LAYNG TERRENCE V
IPC: G09B5/06
Filed: 2002-01-16
Abstract: A method and system provides procedures/routines to teach certain repertoires, such as reading, to learners (44) without a teacher present. The various routines can be provided or implemented via a computer network (12), such as the Internet, so that multiple learners (44) can access and use the routines.  Feedback features take into account that the Internet is a medium where it is difficult to directly monitor the learner's activities during the course of various lessons provided by the routines. The routines may be implemented in a sequence of episodes, with each episode systematically building on the particular skills learned in a prior episode. Some of these routines include establishing routines, adduction routines, potentiating routines, composite routines, sequential composite routines, fluency routines, motivation routines, application routines, and the overall sequencing of these routines.

Patent CA-2439002-A1 (CA)
Inventor: DEMPSEY MICHAEL K
IPC: H04W4/029
Filed: 2002-03-11
Abstract: Le mode de réalisation illustré de la présente invention décrit un procédé permettant d'enregistrer des associations d'objets au moyen d'un système de localisation. Des emplacements d'objets sont déterminés en fonction de signaux créés à partir d'identificateurs d'objets liés aux objets, puis ils sont transmis à un dispositif électronique en interface avec un réseau. L'origine du signal est calculée par un module déterminant les emplacements, en fonction de divers facteurs, notamment la position connue des récepteurs recevant le signal, la position enregistrée historique de l'objet, les caractéristiques des récepteurs recevant le signal (c'est-à-dire la portée), la force du signal reçu, le type de signal et le fait que le signal ait été répété ou non. Une fois l'emplacement de l'objet déterminé, le module déterminant les emplacements consulte une base de données pour déterminer des associations entre l'objet localisé et d'autres objets ou emplacements spécifiés, en fonction de la proximité des autres objets de l'objet localisé. Une fois l'association déterminée, celle-ci est stockée et sa durée est ultérieurement enregistrée. Les données issues des associations identifiées peuvent alors être utilisées de plusieurs manières en tant que données d'entrée pour diverses applications, telles qu'un logiciel de facturation, un logiciel d'utilisation d'équipement, un logiciel de gestion d'actifs et un logiciel de création d'événements automatique.

Abstract: L'invention concerne des scènes dans un film nécessitant une colorisation. On découpe ces scènes en différents éléments distincts, composés de fonds/décors ou de mouvements/actions à l'écran. Ces éléments de fond et ces éléments de mouvement sont combinés séparément comme des représentations à image unique d'images multiples, comme des ensembles d'images juxtaposées ou comme un seul composite d'image de tous les éléments (par exemple, mouvements et fonds/arrière-plans) qui deviennent ensuite une base de données de références visuelles contenant des données pour tous les décalages d'image qui seront utilisés ultérieurement pour l'application contrôlée par ordinateur de masques dans une séquence composée de plusieurs images. Chaque adresse de pixel à l'intérieur de la base de données de références visuelles correspond à une adresse de tableau de masque/détection à l'intérieur de l'image numérique et la localisation X, Y, Z d'images subséquentes qui ont été utilisées afin de créer une base de données de références visuelles. On applique des masques aux images subséquentes d'objets en mouvement à partir de différents procédés de traitement d'image par différenciation, incluant un ajustement de masque automatisé de tous les masques dans une image complète, l'ajustement de masque automatisé de masques uniques dans chaque image, le tracé de Bézier et de polygone de régions sélectionnées à l'aide d'une mise en forme de bord détecté et la détection dirigée par un opérateur de régions subséquentes correspondant à la région d'origine présentant un intérêt. Ainsi, l'échelle de gris détermine activement le masque et la détection de couleur correspondante image par image qui est appliquée par manipulation à l'intérieur des différentes régions présentant un intérêt.

Title: Fuel cell ambient environment monitoring and control apparatus and method
Inventor: DEO HARVINDRA
IPC: H01M8/04
Filed: 2002-07-25
Abstract: An electrochemical power generation system includes a fuel cell stack having an oxidant delivery system for delivering air from the ambient environment to the oxidant inlet of the stack, an oxygen sensor for measuring the oxygen concentration of ambient air in the vicinity of the power generation system. A  controller coupled to the oxygen sensor is configured to cease operation of the power generation system when the oxygen concentration of the ambient air in the vicinity of the power generation system falls below an oxygen concentration threshold. The power generation system may also include a purge valve associated with a fuel outlet from the stack. The controller is coupled to the purge valve and configured to intermittently open the purge valve such that the hydrogen discharged from the fuel cell stack during operation of the power generation system does not cause the hydrogen concentration in the vicinity of the power generation system to exceed a high hydrogen concentration condition before the oxygen concentration in the vicinity of the power generation system falls below the oxygen concentration threshold.

Title: Inflation valve assembly for a dunnage or cargo air bag
Inventor: SMITH RODNEY S
IPC: F16K15/20
Filed: 2004-07-02
Abstract: An inflation valve assembly, for a dunnage or cargo air bag, comprises an annular flange member which is adapted to be heat-sealed to an interior surface portion of one of the plies of the inflatable bladder of the air bag, and an externally threaded nipple portion for fluidic connection to a source of pressurized fluid for inflating the bladder of the dunnage or cargo air bag. The inflation valve assembly also has a substantially C-shaped upstanding ring member integrally disposed upon the upper surface portion of the annular flange member, and a substantially planar, disc-type flapper valve member, having a substantially circular configuration, has an end portion which is adapted to be fixedly secured upon an arcuate portion of the upper surface portion of the annular flange member by means of a fixation bar which extends along a chordal extent of the annular flange member.      Opposite end portions of the fixation bar project radially inwardly toward each other so as to effectively define a pair of oppositely disposed detents for maintaining the flapper valve member in its OPENED state. Accordingly, the height dimension or depth profile of the new and improved inflation valve assembly of the present invention is able to be substantially reduced so as to enable the inflation valve assembly to readily facilitate the sealing of the inflatable bladder during the fabrication thereof.
