Abstract:
A cable guided shade system can include a head rail at least one guide cable anchor spaced from the head rail, and at least on guide cable that is fixed to the head rail and extends to the guide cable anchor. The guide cable anchor is configured such that the guide cable can be tensioned at the guide cabled anchor. The system further includes a covering material that is fixed to the head rail and is configured to move along the guide cable between an open position and a closed position.
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 motor drive unit assembly for a motorized drapery system having a drapery fabric can include a motor having a drive shaft, an output member rotatable about a drive axis, such that rotation of the output member about the drive axis causes the drapery fabric to move, and a clutch member operatively coupled between the drive shaft of the motor and the output member. The clutch member is configured to automatically couple the output member to the drive shaft such that rotation of the motor drive shaft causes the output member to rotate about the drive axis when the motor drives the drive shaft. The clutch member is further configured to automatically decouple the output member from the motor drive shaft so that the output member rotates about the drive axis relative to the motor drive shaft when the output member is manually driven.

Abstract:
A battery-powered motorized window treatment for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery that is powering the motorized window treatment. A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries without unmounting the headrail and without requiring tools. The motorized window treatment may comprise brackets having buttons that may be actuated to release the headrail from a locked position, such that the head rail may be rotated into the service position. The headrail easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment into the service position and change the batteries.
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 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).
