    Abstract: An aerodynamic measurement probe intended to measure a local angle of attack of an airstream flowing along the fuselage of an aircraft, comprises a support and a shaft that is able to rotate about a longitudinal axis with respect to the support. The support and the shaft are configured to form between one another a plurality of successive chicanes about the longitudinal axis. Each chicane makes it possible to transport liquid that has penetrated into the chicane: along a first path, under the effect of gravity, towards an evacuation circuit associated with the chicane and formed in the support, and along a second path, and counter to the effect of gravity, towards a successive chicane or towards the shaft. The evacuation circuit of each of the chicanes makes it possible to evacuate liquid out of the support under the effect of gravity moving away from the shaft.

    Abstract: A trackball that is used notably for pointing at objects on a screen of a computer system comprises a body that is intended to be fixed to a workstation, a sphere that is rotatable with respect to the body, a set of sensors that provide information relating to the relative position of the sphere with respect to the body, and braking means for braking the rotational movements of the sphere with respect to the body. The braking means comprise a friction ring that encircles the sphere. The ring extends mainly in a plane perpendicular to an axis of symmetry of the sphere. The ring is free to move translationally in the plane in which the ring extends.

    Abstract: A data input device comprises a body intended to be fixed onto a workstation, a part that is rotationally mobile in relation to the body, a set of sensors delivering information on the relative position of the mobile part in relation to the body and means for braking the rotational movements of the mobile part in relation to the body. The braking means comprise a friction ring encircling the mobile part, the ring being split and extending mainly in a plane at right angles to an axis of symmetry of the mobile part, an annular spring extending in the plane and radially compressing the friction ring against the mobile part and means for adjusting the length of the annular spring.
