Inventor: KURZ ARTHUR
IPC: H03F1/30
Filed: 1988-08-05
Abstract: Apparatus for the reproduction of data, which can be read contactlessly from a recording medium by means of an optical pick-up device. 
<??>Such apparatuses are equipped with a focus control circuit, in order to focus the light beam picking up the data onto the recording medium, and with a tracking control circuit, in order to be able to guide the light beam on the data tracks. The light beam is reflected from the recording medium onto a photodetector (PD) comprising a plurality of photodiodes (E, F). Because actual photodiodes (E, F) are not completely identical, they give off different photoelectric voltages under the same illumination. Therefore, the control amplifier (TR) of the tracking control circuit operates unsymmetrically. 
<??>In order to bring the operating point of the control amplifier (TR) of the tracking control circuit into the optimum centre position, an offset-compensation voltage is applied to an input of the control amplifier (TR) and varied until the photoelectric voltages of the photodiodes (E, F) from which the track error signal (TE) is obtained are of equal magnitude.

Abstract: Dans un procédé de forage thermique pour le percement de tunnels, les forages de grande profondeur et de prospection, on réalise par fusion uniquement une brèche définissant le profile extérieur du tunnel ou du trou de forage. On maintient d'abord immobile la carotte entourée par cette brèche, puis on la fait avancer sur une certaine distance à travers la zone de fusion. De manière appropriée, on découpe la carotte après son passage dans une zone froide et on la fait avancer en continu. La hauteur de la carotte initialement immobile est déterminée de manière à pouvoir injecter sous pression dans la carotte la roche fondue, la pression nécessaire à cette injection sous pression étant maintenue sensiblement constante indépendamment de la profondeur du forage.

Abstract: Dispositif de commande adaptative basé sur la vision, permettant par exemple de commander un bras de robot. Le dispositif de commande comprend: une caméra; un dispositif de segmentation permettant l'analyse d'images provenant de la caméra, concernant leur contenu; un suiveur, un dessinateur et un dispositif de repérage réagissant entre autres aux informations provenant du dispositif de segmentation, afin de créer une liste d'informations segmentées en trois dimensions, un dispositif de reconnaissance destiné à recevoir la liste d'informations et à comparer les informations dans la liste par rapport à une base de données d'objets plausibles; ainsi qu'un planificateur interactif avec le dispositif de reconnaissance, et répondant aux définitions de la tâche afin de développer des parties de commande. Le dispositif de segmentation décompose l'image en régions de teinte approximativement uniforme, puis le dessinateur produit une esquisse de l'image, ladite esquisse se composant d'arcs dont chacun représente une caractéristique significative dans l'image. Le suiveur suit les caractéristiques et les régions d'intérêt à travers une série d'images, et le dispositif de repérage produit des informations de profondeur et d'échelle à partir des vues multiples. Ainsi, le travail du dispositif de repérage consiste à construire une représentation tridimensionnelle de la scène, qui ne change pas par rapport au mouvement de la caméra. Le dispositif de reconnaissance utilise des informations scéniques telles que des plans de caractéristiques produits par le dispositif de segmentation, etc., conjointement avec une base de connaissance, afin de construire un modèle de monde qui est une représentation logique du monde tel qu'il est vu par la caméra. Le planificateur utilise le modèle d'environnement et les définitions de la tâche, afin de construire un plan ayant la forme d'un ensemble d'action, et d'accomplir la tâche définie. Le planificateur produit également des demandes afin d'obtenir davantage d'informations à partir d'autres
