Title: COVER FOR A WINDOW OR DOOR, SUCH AS A (ROLLER) BLIND, A (ROLLER) SHADE, A (ROLLER) SHUTTER, OR THE LIKE, AND SYSTEM COMPRISING A PLURALITY OF SUCH COVERS
Abstract:
The invention relates to a cover system for a window or door, such as a (roller) blind, a (roller) shade, a (roller) shutter, or the like, comprising: - a cover element, such as a roller, a shade, a shutter, or the like; - a rotatable element to which said cover element or a means for retracting and extending said cover element is wounded, said rotatable element being rotatable in a first direction for winding up said cover element or said means for retracting and extending and in a second, opposite direction for unwinding said cover element or said means for retracting and extending; - a motor for rotatingly driving said rotatable element in the first or second direction; and - a (micro) processor configured for controlling said motor in such a way that said rotatable element is rotated with a first chosen speed such that a free end of the cover element is transported at a second chosen speed. The invention also relates to a system, comprising a plurality of cover systems for a window or door, such as a (roller) blind, a (roller) shade, a (roller) shutter, or the like. The invention further relates to a method for measuring the speed of the free end of a cover element of a cover system according to the invention, said method comprising the step of measuring said speed using said sensor. The invention also relates to a method for measuring the presence of the free end of a cover element of a cover system according to the invention at a chosen reference position, wherein said (micro)processor is configured for calculating the speed of the free end of the cover element based on said measured presence and rotational angle of said rotatable element.
