    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.

    Abstract: A battery-powered load control device (e.g., a motorized window treatment) is able to supply a pulse-width modulated current to an electrical load (e.g., a motor) while conducting a substantially DC battery current from a battery powering the motorized window treatment. The motorized window treatment includes a motor drive circuit for driving the motor with a pulse-width modulated signal to adjust the rotational speed of the motor, such that the motor conducts the pulse-with modulated current. The motorized window treatment also has an input circuit coupled between the battery and the H-bridge drive circuit. The input circuit has an output for conducting the pulse-width modulated load current, and conducts the substantially DC battery current from the battery. The input circuit may comprise, for example, a passive filter circuit (such as an inductor-capacitor filter) or an active circuit (such as a power converter).
