Abstract: A method for controlling a shading device includes: moving a screen by electrical activation of an electromechanical actuator; determining a value of data representing operation of a motorised drive device during screen movement; and comparing the determined data to a first predetermined threshold. Depending on the result, the method includes: reducing a rotational speed setpoint of an output shaft of the electromechanical actuator if the value of the determined data?the value of the first predetermined threshold, to reduce power consumed by the electromechanical actuator; or maintaining the rotational speed setpoint of the output shaft of the electromechanical actuator as long as the determined data<the value of the first predetermined threshold. The determined data is the power consumed or the torque delivered by the electromechanical actuator. The determining, comparing, and reducing are iterated until a value of a second predetermined speed threshold is reached.

Abstract: A method is provided for examining the cathodic protection of a metallic and in particular ferromagnetic pipeline. An inspection device is also provided for examining the cathodic protection of a pipeline, in particular of a ferromagnetic pipeline. The inspection device is formed to be able to pass through the pipeline and in particular be driven by the medium, and includes a magnetizing device serving to create an alternating magnetic field. A magnet unit and a measuring device are provided, and includes at least one magnetic field sensor serving to measure a magnetic field formed on the inner side of the wall of the pipeline.
