Roller blind initiation method, involves moving screen in two directions at rapid and slow speeds, and calculating the time required to cover entire course at rapid speed between two ends

摘要

Method for initiation of a device (1) comprising a screen (2) intended to be moved between two extreme positions, an actuator (3) for driving the screen at two different speeds, and a control unit (4) comprising a clock (6) for measuring the times of movement of the screen, a memory (5) and a logic unit (9), comprises: movement of the screen in a first direction at rapid speed, movement in the first direction at slow speed, movement in a second direction at rapid speed, movement in a second direction at slow speed, movement in the first direction at rapid speed, and movement in the first direction at slow speed, and calculation of the time required to cover the entire course at rapid speed between the two end positions in the first and second directions. An independent claim is also included for the device described above.
