  • Motorized roller shade system with a sun angle sensor
    Patent number: 9447635
    Abstract: Presented is a motorized roller shade system. The system includes a flexible shade material, a roller tube configured for windingly receiving the flexible shade material, a shade motor coupled to the roller tube, a motor controller in communication with the shade motor, and a sun angle sensor. The sun angle sensor is configured for determining the angle of the sun and transmitting the angle of the sun to the motor controller. The motor controller is configured for driving the shade motor to rotate the roller tube to wind or unwind the flexible shade material in response to the transmitted angle of the sun to limit sunlight penetration to a predetermined maximum distance into a room.
