Patent number: 11192251Abstract: A method for controlling the operation of a robot within a system. The system includes the robot and sensors to analyze the concentric environment of the system. The sensors include a contact sensor, a proximity sensor and a vision and location sensor. For each of the axes of the robot, a maximum allowable force value is obtained. If the force on one of the axes of the robot is greater than the maximum value, the robot is stopped in its position. A concentric monitoring space or a security space is obtained as a function of the speed of the robot. The environment of the robot is monitored by the sensors. If the intrusion of an object is detected in the safe space of the robot, the maneuvering speed of the robot is gradually decreased to a safe speed. The process is repeated for the next axis of the robot.Type: GrantFiled: November 28, 2016Date of Patent: December 7, 2021Assignees: INSTITUT DE RECHERCHE TECHNOLOGIQUE JULES VERNE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, UNIVERSITE DE NANTESInventors: Christine Chevallereau, Alexis Girin, Philip Long

Publication number: 20210147801Abstract: A population of highly suppressive human CD8+CD45RClow/? Tregs is characterized by expressing Foxp3 and producing IFN?, IL-10, IL-34 and TGF? to mediate their suppressive activity. Accordingly, methods capable of increasing expansion and immunosuppressive capacity of such a population of CD8+CD45RClow/? Tregs are highly desirable for therapeutic purposes. Rapamycin has been shown to increase the expansion and immunosuppressive capacities of the population of CD8+CD45RClow/? Tregs. Accordingly, the method of increasing expansion and immunosuppressive capacity of a population of CD8+CD45RClow/? Tregs includes culturing the population of CD8+CD45RClow/? Tregs in presence of a rapamycin compound.Type: ApplicationFiled: July 12, 2018Publication date: May 20, 2021Applicants: INSERM (INSTITUT NATIONAL DE LA SANTÉ ET DE LA RECHERCHE MÉDICALE), UNIVERSITÉ DE NANTES, CENTRE HOSPITALER UNIVERSITAIRE DE NANTESInventors: Carole GUILLONNEAU, Ignacio ANEGON, Séverine BEZIE
