Abstract

An electronically-controlled roll-up window shade that can easily be installed by a homeowner or general handyman is disclosed. The motorized shade includes an internal power source, a motor, and a communication system to allow for remote control of the motorized shade. One or more motorized shades can be controlled singly or as a group. In one embodiment, the motorized shades are used in connection with a zoned or non-zoned HVAC system to reduce energy usage. In one embodiment, the motorized shade is configured to have a size and form-factor that conforms to a standard manually-controlled motorized shade. In one embodiment, a group controller is configured to provide thermostat information to the motorized shade. In one embodiment, the group controller communicates with a central monitoring system that coordinates operation of one or more motorized shades. In one embodiment, the internal power source of the motorized shade is recharged by a solar cell.

Claims

1. An electronically-controlled motorized roll-up window shade, comprising:

a controller;

a tubular motor provided to said controller, said tubular motor configured to raise and lower a shade material;

a first power source provided to said controller;

a two-way wireless communication system provided to said controller, said controller configured to control said motor in response to a wireless communication received from a group controller, said group controller configured to open and close said motorized shade to produce a desired room temperature during the day and to provide privacy at night.

2. The electronically-controlled motorized shade of claim 1 further comprising a light sensor.

3. The electronically-controlled motorized shade of claim 1, further comprising a temperature sensor.

4. The electronically-controlled motorized shade of claim 1 further comprising a second power source.
