Abstract: A motorized window treatment system may include a roller tube, a covering material windingly attached to the roller tube, and a drive assembly that may be at least partially disposed within the roller tube. The drive assembly may include a motor having a drive shaft that is elongate along a longitudinal direction and a drive gear attached to the drive shaft such that a toothed portion of the drive gear is cantilevered with respect to the drive shaft. The drive assembly may include a gear assembly having a pair of intermediate gears on opposed sides of the drive gear. Rotation of the drive gear may be transferred through the pair of intermediate gears, a connecting gear, a planetary gear set, a cage, and an idler to the roller tube. Rotation of the roller tube may cause the covering material to move between an open position and a closed position.

Abstract: A magnetic levitation system for sliding door and window, includes at least a movable module for the lower part of the sliding door and window which includes one or more permanent magnets; several fixed modules for the lower part of the frame of the sliding door and window, which includes one or more electromagnets to produce a variable repulsive magnetic field of the magnetic field of said magnets of the movable module. It has the advantage of eliminating the friction, mechanical wear and noise associated to the sliding, allowing, when deactivated, a greater air and water tightness and terminal and acoustic insulation, allowing the electromagnetic closure or locking of the door and window, increasing the security, and as is a modular system its operation and construction are simpler and more economical.
