Abstract: Un système de chirurgie robotique comprend plusieurs manipulateurs d'outils chirurgicaux comprenant des manettes exploitées par un utilisateur pour manipuler de multiples outils chirurgicaux, dont des effecteurs pour lesquels la position et l'orientation sont déterminées en fonction des positions et des orientations des manettes. Un processeur est configuré pour déterminer de nouvelles positions et orientations d'effecteurs en fonction des positions et des orientations actuelles des manettes et déterminer un ensemble de distances de chaque point d'un premier ensemble de points le long d'un premier outil chirurgical à chaque point d'un deuxième ensemble de points le long d'un deuxième outil chirurgical. Le mouvement des effecteurs est désactivé si l'une des distances satisfait à un seuil de proximité entraînant les effecteurs à rester à leurs positions et orientations précédentes respectives. Si aucune distance ne satisfait au seuil de proximité, les effecteurs sont positionnés et orientés à leurs nouvelles positions et orientations respectives.

Abstract: FIELD: fittings production. SUBSTANCE: bore 2 of valve body 1 has stepped end face. Lower step 20 is engageable with end face of insertion sleeve 11 and upper step 16 serves as bottom of annular groove 17 accommodating gasket 12 tightly enveloping sleeve 11. In the course of valve assembly cover 13 acts upon peripheral part 6 of metal diaphragm 4, moves sleeve 11 down and makes not compressed gasket 12 come in contact with step 16 of bore end face. Further movement of cover forces peripheral part 6 of diaphragm 4 to interact with gasket 12. Further joint displacement of sleeve 11 and diaphragm 4 results in compression of gasket 12 until lower end face of sleeve 11 thrusts against lower step 20 of bore 2. Distance between upper end face 19 of sleeve 11 and its lower end face exceeds height of gasket, deformation of gasket does not accompanied by its overload. EFFECT: improved reliability of valve due to better conditions of gasket deformation. 1 dwg
