Patent CA-2281116-A1 (CA)
Inventor: PRIMEAU GILLES
IPC: H04N13/00
Filed: 1999-08-25
Abstract: For implementing an anthropomorphic visual telepresence system with high resolution and low loop latency a sequential colour video loop is provided. A  sequential colour camera sequentially captures colour images, each captured image consisting of a portion of a single colour component, and provides information as separate colour information relating to portions of the sequentially sensed colour images. The information is transmitted as separate colour information. A sequential colour display receives the transmitted information and displays sequentially each colour image within the received information. Synchronization means synchronize the sequence and colour of corresponding portions of images comprising a single colour in said display with the portions of the images sensed by said camera.

Title: Single-ended subscriber loop qualification for xdsl service
Inventor: LIU GIN
IPC: H04B17/309
Filed: 1999-08-31
Abstract: A method and apparatus for single-ended qualification of subscriber loops for xDSL services is described. The method involves first screening a subscriber loop database record for disqualifying devices or services on the subscriber loop. If note are found, a set of predetermined electrical characteristics of the subscriber loop are derived from information in the database, or directly measured using test equipment at a central office end of the subscriber loop. The electrical characteristics are used to compute an available bandwidth on the subscriber loop for xDSL services. The advantage is the rapid and inexpensive qualification of subscriber loops which reduces response time to potential customer queries and facilitates deployment of xDSL services.

Inventor: HOERBER ERNST
IPC: G01S17/04
Filed: 1998-02-26
Abstract: When detecting an object in a given area, especially vehicles for the purposes of traffic control, there appear to be inaccuracies in the system based on measuring pulse propagation times. In order to avoid such inaccuracies, a sample of observed (measured) real values is compared with a gauging table having a sample of values stored therein, so that pulse propagation time measurements are no longer necessary.

Title: Picutres replacement system and method of the same
Inventor: KOGUMA TORU
IPC: H04N5/272
Filed: 1999-03-18
Abstract: A reference image used as a reference of a replacement area, a reference position of the replacement area, the size of the replacement area, and logo images for replacement are stored. A rotary encoder provided to a tripod head of a camera measures the amount of two-dimensional movement of the camera and outputs the measured amount as movement information. An image synthesizer calculates the address of a reference position of a replacement area in the current image, and detects the replacement area with respect to the address. A key signal indicating whether the current image in the replacement area is the same as the reference image or is different from the reference image is generated, and the portion where the current image accords with the reference image is replaced with a logo image, selected from among the logo images, corresponding to the portion according to the key signal.

Abstract: A method and an apparatus for obtaining the shape of a piece circulating on a conveyor is provided. Profiles of the piece are taken are intervals of time and distance with respect to the speed of the traveling piece. The profiles can be taken using laser diodes. A camera captures an image of the profiles and stores the image. The shape of the piece is then built, on a screen, using the data collected during the acquisition of the profiles. The last profiles of the first acquisition set and juxtaposed to the first profiles of the next acquisition set in order to position the subsequent profiles. The shape of the whole piece is therefore built and can be transmitted. The image can be used to discard pieces with defects or to calculate a relative quality of the piece.

Abstract: Méthode pour obtenir par un processus d'inversion, un modèle optimal d'une caractéristique physique dans un milieu hétérogène (l'impédance d'une zone souterraine relativement à des ondes transmises dans le sol, par exemple), en partant d'un modèle a priori de cette grandeur que l'on optimise en minimisant une fonction-coût dépendant des écarts entre le modèle recherché et les données connues, compte-tenu du modèle a priori. - La construction du modèle a priori comporte une corrélation par krigeage entre les valeurs de la grandeur physique connues en différents points du milieu suivant des discontinuités (directions de strates). Les incertitudes sur les valeurs de la grandeur physique dans le modèle a priori par rapport aux valeurs correspondantes dans le milieu obéissent à un modèle de covariance qui contrôle de façon plus quantitative les paramètres d'inversion, les caractéristiques de ce modèle de covariance étant définies en liaison avec la structure des données observées ou mesurées dans le milieu. L'interprétateur est ainsi mieux guidé dans la sélection des paramètres d'inversion. - Applications à la localisation de gisements d'hydrocarbures par exemple.

Title: Shift mechanism for a vehicle gearbox
Inventor: FRITZ MARTIN
IPC: F16H61/36
Filed: 2000-05-08
Abstract: A shift mechanism for a vehicle gearbox, in particular for a shift gearbox of an agricultural or commercial vehicle that is spaced away from the vehicle gearbox and is connected with the vehicle gearbox by shifter rods or shifter cables. The shift mechanism contains at least one shift lever supported in bearings in a housing so as to pivot and is used to shift gear ratios. The shift lever engagement region located in the interior of the housing engages transfer elements supported in bearings so as to slide parallel to each other and is forced by a reset mechanism into a neutral position. At least one shifter rod or at least one shifter cable connected to the vehicle gearbox is fastened to each transfer element. In order to exclude any risks to safety that could occur by the unintentional engagement of a gear ratio during maintenance or repair operations it is proposed that the shift lever, while in its neutral position interacts by its engagement region simultaneously with at least two transfer elements whereby a relative movement of the transfer elements with respect to each other and thereby the engagement of a gear ratio is prevented.
