  • Patent number: 11192251
    Abstract: 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.

  • Patent number: 11131544
    Abstract: An optical fiber curvature sensor. Two networks (R1, R2) with periodic longitudinal modulation of the refractive index of the optical fiber core are inscribed in the fiber (F) one behind the other or one on top of the other. The networks are configured to respectively reflect wavelengths ?1 and ?2 such that ?1=?B+??B1 and ?2=?B+??B2, where ?B is the Bragg wavelength of the networks and where ?B1 and ?B2 are shifts sensitive to the temperature, to deformations and to the curvature of the optical fiber. The two networks are defined so that the quantities ??B1 and ??B2 have substantially identical sensitivity to temperature and to deformations and substantially opposite sensitivity to curvature.

  • Publication number: 20210283271
    Abstract: The invention is directed to the field of gene therapy, i.e. gene delivery into target cells, tissue, organ and organism, and more particularly to gene delivery via viral vectors. The inventors showed that it is possible by chemical coupling to modulate the coupling of a ligand in the surface of the capsid of AAV, for example AAV2 and AAV3b. In particular, the present invention relates to a recombinant Adeno-Associated Virus (rAAV) vector particle having at least one primary amino group contained in the capsid proteins, chemically coupled with at least one ligand L, wherein coupling of said ligand L is implemented through a bond comprising a —CSNH— bond and an optionally substituted aromatic moiety. Particularly, the inventors tested the chemical coupling of mannose ligand on AAV2 for subretinally injection to rats.

  • Publication number: 20210147801
    Abstract: 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.
