Date May 24, 1984.A single mode optical fiber switch having a base (70) and a laterally slidable top (91). The base is composed of a quartz block (70) with a slight radius of curvature along its length supporting a silicon substrate (66) having a plurality of parallel v-grooves (68). The grooves are fitted with single mode optical fiber segments (64) and lapped to create a flat coupling surface (82) extending laterally across the base. The top (91) is composed of a quartz block with a single v-groove (93) holding a segment of single-mode fiber (95). This fiber (95) is lapped to create a flat coupling surface matable with the coupling surface on the base. The base (70) and top (91) are placed together such that the top fiber (95) may be selectively slid into and out of coupling alignment with any of the fibers (64) in the base (70) to form a discretely variable delay line. A single length of fiber (121) is wrapped around the base ( 70) in helical fashion with each loop being secured in one of the v-grooves (68). By coupling the top fiber (95) with different loops of the base fibers (121), different amounts of delay can be obtained. The delay line can be used to provide variable frequency response for notch and transversal filters.

Abstract: Des données indiquant les fissures détectées dans un revêtement routier sont reconnues automatiquement grâce à un ordinateur (4). La mémoire d'image stockant les données relatives au revêtement routier est divisée en une pluralité de régions. Quelques-unes de ces données de régions indiquent une fissure (LP), et l'une quelconque d'entre elles peut être un point de départ de traçage. Un segment de ligne (SG) correspondant à la fissure (LP) est extrait d'une région de départ. La direction de traçage suivante est déterminée en fonction de la direction de la ligne () du segment de ligne extrait (SG), et on détermine s'il existe une fissure (LP) dans la région avoisinante dans la direction du traçage. Les segments (SG) ne sont extraits que des régions dans lesquelles on a trouvé des fissures (LP). Cette procédure commence à chaque point de départ et se répète jusqu'à l'achèvement du traçage. Par conséquent, les données relatives aux fissures dans la mémoire d'image sont extraites sous forme de combinaisons de segments de ligne (SG). Dans ce procédé, les segments ne sont pas nécessairement extraits de toutes les régions, ce qui permet d'augmenter la vitesse de traitement.

Abstract: Procédé de commande de mode de glissement réduisant l'écart de position constant de la cible de commande et améliorant la stabilité de commande par l'adaptation du système de commande à toute modification du paramètre du système. Le processeur dans un servocircuit numérique du système de servocommande calcule l'écart de position (ε), l'écart de vitesse (ε), une valeur du plan de commutation (s) et une valeur d'un élément d'intégration (∫(ε + C.ε) dans le plan de commutation (100 à 102, 107, 113) en fonction d'une position de consigne (Υr) et d'une position réelle (Υ). Le processeur calcule en outre un premier terme et un deuxième terme d'une quantité de commutation (T1) selon une formule de calcul déterminée en fonction du plan de commutation, de l'écart de position et du signe positif ou négatif correspondant à la valeur de l'élément d'intégration (103 à 115). Ensuite, en fonction de la valeur calculée de la quantité de commutation (T1) qui est égale à la somme des premier et deuxième termes et qui satisfait la condition de stabilisation de Liapunov, on calcule une instruction de couple (T) qui est suffisante pour faire converger les caractéristiques du système de commande vers le plan de commutation (s = 0). Il en résulte que le système de commande ne perd pas sa stabilité, même en cas de modification des paramètres du système.
