  • Publication number: 20240045462
    Abstract: The present disclosure relates to a human-machine interface, in particular for a vehicle or for a device, comprising at least one gripping element comprising at least one transducer transmitting a command depending on at least one item of input information. The human-machine interface comprises at least one sensor and calculation means configured to determine a position of at least one interaction surface for interaction between an operator and the gripping element, the calculation means also being configured to determine whether the command is intentional by determining whether at least one first predefined surface lies at least partially within the interaction surface, so as to authorise the transmission of the command by the human-machine interface when it is determined that the command is intentional.

  • Patent number: 11628925
    Abstract: The present invention relates to a force application device for a control stick of an aircraft comprising a shaft and a control lever configured to rotate the shaft about a first axis, the device comprising: a magnetic brake comprising a braking part configured to be connected to the shaft, and a volume containing a rheological fluid in contact with the braking part, of variable shear resistance as a function of a magnetic field applied to the rheological fluid, a force feedback motor configured to exert a resistive force opposing the rotation of the shaft about the first axis, a motor power source, a movable magnetic element biased towards a position close to the magnetic brake, and distancing means configured to maintain the movable magnetic element in a position away from the magnetic brake, when such distancing means are powered by the power source.

  • Patent number: 11433989
    Abstract: The present invention relates to a force application device for a control stick of an aircraft, wherein the control stick comprises a control lever (1) rotating a shaft (A1) about a first axis (A), the device comprising a magnetic brake (5a) which comprises a magnetisable element (50a) mounted on the shaft and a magnetic transmitter (51a) which is opposite the magnetisable element and free to rotate about the first axis relative to the magnetisable element, the magnetic transmitter having an activated state in which the magnetic transmitter is supplied with current and generates a magnetic field in a volume occupied by the magnetisable element, and a deactivated state in which the magnetic transmitter is not supplied with current and does not generate a magnetic field, so as to prevent the magnetisable element from rotating about the shaft relative to the magnetic transmitter.
