  • Patent number: 11840885
    Abstract: A method for detecting an obstacle opposing the movement of a screen in a home automation closure or sun protection system includes an electromechanical actuator driving movement of the screen. The electromechanical actuator includes a torque support, a housing, an output shaft, and an electric motor including a stator and a rotor. The system includes a winding shaft rotating the screen and a connecting accessory between the electromechanical actuator's output shaft and the winding shaft. The method includes: determining an angular displacement value of the rotor with respect to the stator; determining angular displacement of the winding shaft relative to the housing or torque support of the electromechanical actuator; determining angular deformation of the kinematic chain between the electric motor and the winding shaft by comparing these two angular displacements; and determining the presence of an obstacle to screen movement from an angular deformation exceeding a predefined value.

  • Patent number: 11781378
    Abstract: A shading device comprises a power supply device comprising a battery, a first and a second electrical connection elements and a resilient element. The battery is disposed at a holding device for holding the screen. The first element is disposed at a load bar or the screen and configured so as to be electrically connected to an external electrical supply source. The second element is disposed at the holding device and configured to cooperate with the first element. The resilient element is configured to be fixed on the load bar or on the screen. The first element is integral with the resilient element. Furthermore, the resilient element is configured to compensate a misalignment of the first electrical connection element with respect to the second electrical connection element, when the screen reaches a position for recharging the battery.
