Abstract:
A data-input device comprises a designator able to point to a position on a screen of a computer system to which the device is intended to be connected and a body intended to be fixed to a workstation, the body comprising a support zone intended to support the hand of an operator as he manipulates the designator. The device further comprises a knob arranged in such a way that it can be manipulated by the fingers of the operator, his hand remaining supported on the support zone. The knob is configured to allow at least two distinct data selections of which one is a choice of values in a series and one is a binary acquisition in relation to the chosen value.
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 device for endorsing screwed assemblies, includes a screw gun intended to be handled by an operator, and computer equipment connected to the screw gun, the screw gun being equipped with measurement sensors sending information representative of the torque applied by the screw gun and an angle of rotation applied by the screw gun, the computer equipment storing, in a memory, reference data relating to a screwed assembly to be produced, the computer equipment being configured to compare information representative of the angle and the torque measured during the assembly with the reference data, and to provide a notification as to the conformity of the measurements of the angle and the torque in relation to the reference data.
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.
Abstract:
The securing of a data input device of a computer system including a screen, the device including a touch-sensitive surface allowing an object displayed on the screen to be designated, and a switch operable by pressing the touch-sensitive surface, the operation of the switch allowing a designated object to be selected. The device furthermore includes means for measuring a force applied to the touch-sensitive surface and intended to operate the switch. The measurement means are independent from the switch.
