    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 variable resistance brake may be operably coupled to a window treatment, such as to the roller tube of a motorized roller shade. The variable resistance brake may generate a first braking force that resists rotation of the roller tube in a first rotational direction, and a second braking force that resists rotation of the roller tube in a second rotational direction. The first and second braking forces may have different magnitudes. The variable resistance brake may include an idler, a mandrel that is operably coupled to the idler, a spring that rides on the mandrel, and a bearing that is configured to operably engage with the roller tube and that is rotatable about the idler. The idler may be configured to be supported in a fixed position relative to the roller tube. The spring may define a first end that is fixed in position relative to the bearing.

    Abstract: A motorized window treatment provides a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment includes a covering material, a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery is used to power the motorized window treatment. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors to save energy, or may also be controlled in response to an infrared or radio-frequency remote control.
