| 1. An initialization process, for determining the position of a screen and for the control of the movement of said screen
(2) designed to move between two extreme positions, the screen being associated with a control unit (4) which comprises a clock (6), a memory (5) and a logic processing unit (9) and which controls an actuator (3) driving the screen (2), in which process
the travel of the screen between the two extreme positions is divided into different segments and
each segment end is allocated a duration of screen movement in a first direction between the segment end and a first reference
position and a duration of screen movement in a second direction between the segment end and a second reference position,
wherein each position of the screen is determined by the duration separating the screen from at least a reference position.
