Abstract: A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.

Abstract: A position-fixing system includes a pole, a guiding member adjacent to the pole, and a movable member fitting around the pole. The pole is immovable relative to a window covering. The guiding member includes a principal axis parallel to an extension axis of the pole, and includes a retaining face substantially extending in the direction of the principal axis, but non-coplanar with it. The movable member corresponds to the retaining face. The movements of the movable member and the guiding member are related to that of a shaft of the window covering. When the window covering is being operated, the movable member is driven to rotate around the pole, and moves along the pole and the guiding member. Due to the retaining face, the movable member keeps contacting the pole to create a friction therebetween. Therefore, the position of a covering material of the window covering can be precisely fixed.
