  • Damping device capable of providing increased stiffness
    Patent number: 8547191
    Abstract: Damping device to impose a reaction to the displacement of a manual operating device (28), said device comprising at least one chamber containing the magneto-rheological fluid, one or two means of generating a variable magnetic field (6.1, 6.2) in the magneto-rheological fluid so as to modify its apparent viscosity, one element (4) free to move in translation capable of shearing the magneto-rheological fluid and designed to be mechanically connected to the manual operating device (28), said mobile element (4) comprising a blade with a longitudinal axis (Y) comprising holes and/or recesses and/or projections.
    Type: Grant

  • TACTILE OR HAPTIC DEVICE, AND A MUSICAL KEYBOARD WITH AT LEAST ONE SUCH SIMULATION DEVICE
    Publication number: 20100031803
    Abstract: A tactile or haptic sensation simulation device designed to oppose the movement of a manual control component with a reaction reflecting the movement of the control, where the said device has a chamber containing a magneto-rheological fluid, a mobile element interacting mechanically with the fluid and intended to be linked mechanically to the control component, where the said element is mobile between two predetermined positions, at least one sensor with a cinematic and/or dynamic range that is representative of the movement of the control component, a control component and means for the generation of a suitable magnetic field around the chamber so as to apply a magnetic field that is dependent on the dynamic characteristics to be simulated for the movement of the manual control component, and the real-time measurements, the whole being such that the apparent viscosity of the magneto-rheological fluid varies over the travel of the manual control component.
