Abstract: Fiber positioning unit of SCARA type comprising an alpha (1,2,3) and a beta mechanism (4,5); the alpha mechanism successively comprising a motor (1), a driving shaft (2) and a rotatable shaft (3), the rotation of the rotatable shaft (3) being carried out by the alpha motor (1) via the driving shaft (2); the beta mechanism comprising a motor (4) and a fiber holding element (5) that may be rotated by the beta motor (4); both mechanisms being mechanically connected in a way to allow a rotation of the beta mechanism (4,5) by the rotatable shaft (3); the alpha mechanism (1,2,3) being furthermore adapted to be partially located within a focal plate (6), characterized by the fact that the alpha motor (1) is adapted to be located on one side of the focal plate (6) while the rotatable shaft (3) and the beta mechanism (4,5) are adapted to be located on the other side of the focal plate (6).

Abstract: A guidance system for guiding the displacement of a movable element with respect to a fixed element. The guidance system includes a linear actuator, the fixed element having a main guide axis, a secondary guide axis, the movable element being arranged to be displaced by the linear actuator with respect to the fixed element along a first axis (z). The movable element includes: a first rolling bodies guide device cooperating with the main guide axis, arranged to block four degrees of freedom of the movable element, a second rolling bodies guide device cooperating with the secondary guide axis, arranged to block a rotation of the movable element about a third axis (z).

Abstract: The invention relates to a method of manufacturing a bearing (100) for a medical rolling bodies guide device, comprising components, at least one component (20; 6, 2, 4, 5, 5?) being made of titanium or a titanium alloy, the method comprising the steps of processing the titanium or titanium alloy component; performing a diffusion hardening treatment of the machined component, so that the component comprises a surface layer (21) having a hardness in the range 900 Hv-1100 Hv. The invention makes it possible to manufacture a medical rolling bodies guide device in a material which does not a priori have the properties required for these applications.

Abstract: The present invention concerns an angular transmission device comprising: An input shaft and an output shaft, An assembly arranged for coupling the input shaft with the output shaft so that the output shaft can be rotationally driven by the input shaft, the assembly comprising a rotary actuator and a linear mobile, the rotary actuator being coupled with the input shaft and moves the mobile in a translation motion relative to the actuator, the mobile being coupled with the output shaft so that the rotation of the input shaft drives the rotation of the output shaft; the assembly further comprises a flexible blade fixed to said mobile and looped around the output shaft, so that when the actuator moves the mobile, the flexible blade drives the rotation of the output shaft. The invention also comprises a method using said device.

Abstract: An implantable device comprising a driving unit and a kinematic assembly joined together: the driving includes, in an hermetic capsule, electromechanical component, like an electric motor and, the battery pack, and electronic elements, while the kinematic assembly includes a reducer and an actuator, for example a lead-screw distractor, and is lubricated by body fluids. Mechanical energy is transmitted without contact from the former to the latter by a magnetic transmission.
