Abstract

Methods and apparatus to control architectural opening covering assemblies are disclosed herein. An example architectural opening covering assembly includes a manual controller operatively coupled to a tube to rotate the tube. The tube includes an architectural opening covering. The example architectural opening covering assembly also includes a motor operatively coupled to the tube to rotate the tube. A local controller is communicatively coupled to the motor to control the motor. The example architectural opening covering assembly further includes a gravitational sensor to determine an angular position of the tube.

First claim

What is claimed is:

1. An architectural opening covering assembly, comprising:
a manual controller operatively coupled to a tube to rotate the tube, the tube including an architectural opening covering;
a motor including a motor housing and a motor shaft;
a clutch assembly including a clutch and a clutch housing in which the clutch is disposed, wherein the clutch housing, the tube, and the motor housing are coupled to rotate together;
a gravitational sensor constructed to determine an angular position of the tube; and
a local controller communicatively coupled to the motor, the local controller constructed to:
determine which one of rotation of the tube in a first direction or rotation of the tube in a second direction is to cause the architectural opening covering to wind or unwind around the tube;
detect movement of the tube using the gravitational sensor;
determine whether the movement of the tube is caused by one or both of the motor and the manual controller; and
operate the motor based on the movement and the cause of the movement, wherein, when the motor operates, the clutch enables relative movement between the motor shaft and the clutch housing so that operation of the motor causes the motor housing to rotate, rotating the clutch housing and the tube.

2. The architectural opening covering assembly of claim 1 , further including a central controller communicatively coupled to the local controller, wherein a position of the covering is controlled via one or more of the manual controller, the local controller, and the central controller.

3. The architectural opening covering assembly of claim 1 , wherein the gravitational sensor is an accelerometer.

4. The architectural opening covering assembly of claim 1 , wherein the gravitational sensor is disposed along an axis of rotation of the tube.

5. The architectural opening covering assembly of claim 1 , wherein the local controller is constructed to cause the motor to at least one of assist movement or counter movement of the covering by the manual controller.

6. The architectural opening covering of claim 1 , wherein operation of the manual controller is constructed to counteract rotation of the tube by the motor.

7. The architectural opening covering of claim 1 , wherein the local controller is constructed to determine a position of the architectural opening covering based on the angular position of the tube.

8. The architectural opening covering of claim 7 , wherein the local controller is constructed to store one or more positions of the architectural opening covering, the positions selectively adjustable via the manual controller.

9. A tangible computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
determine which one of rotation of a tube in a first direction or rotation of the tube in a second direction is to cause an architectural opening covering to wind or unwind around the tube;
detect movement of the tube of the architectural opening covering assembly;
determine whether the movement of the tube is caused by one or both of a motor and a manual controller, the manual controller operatively coupled to the tube, the motor including a motor housing and a motor shaft, the motor housing coupled to a clutch housing of a clutch assembly, the clutch assembly including a clutch and the clutch housing in which the clutch is disposed, wherein the clutch housing, the tube, and the motor housing are coupled to rotate together; and
operate the motor based on the movement and the cause of the movement, wherein when the motor operates, the clutch enables relative movement between the motor shaft and the clutch housing so that operation of the motor causes the motor housing to rotate, rotating the clutch housing and the tube.

10. The tangible computer readable storage medium of claim 9 , wherein the instructions, when executed, cause the machine to operate the motor to assist movement of the tube by the manual controller.

11. The tangible computer readable storage medium of claim 9 , wherein the instructions, when executed, cause the machine to operate the motor to counter movement of the tube by the manual controller.

12. The tangible computer readable storage medium of claim 11 , wherein the instructions, when executed, cause the machine to counter movement of the tube by the manual controller to substantially prevent the tube from unwinding the architectural opening covering at least partially wound around the tube past a threshold position.

13. The tangible computer readable storage medium of claim 9 , wherein the instructions, when executed, cause the machine to terminate operation of the motor in response to operation of the manual controller.

14. The tangible computer readable storage medium of claim 9 , wherein the instructions, when executed, further cause the machine to:
enter a programming mode in response to a command from the manual controller;
determine a position of the tube; and
store the position of the tube.

15. The tangible computer readable storage medium of claim 14 , wherein the instructions, when executed, cause the machine to determine the position of the tube using a gravitational sensor.

16. The tangible computer readable storage medium of claim 9 , wherein the instructions, when executed, cause the machine to:
rotate the tube in the first direction; and rotate the tube in the second direction.

17. The tangible computer readable storage medium of claim 16 , wherein the instructions, when executed, further cause the machine to at least determine an amperage of a first signal transmitted to the motor to rotate the tube in the first direction and an amperage of a second signal transmitted to the motor to rotate the tube in the second direction.

18. The tangible computer readable storage medium of claim 9 , wherein the instructions, when executed, cause the machine to:
operate the motor to lower the architectural opening covering by causing rotation of the tube; and
determine a position of the tube at which the architectural opening covering is substantially fully unwound.

19. The tangible computer readable storage medium of claim 18 , wherein the instructions, when executed, cause the machine to operate the motor to lower the architectural opening covering by causing the motor to apply an amount of torque to the tube less than an amount of torque applied to the tube by a weight of the architectural opening covering.

20. The tangible computer readable storage medium of claim 18 , wherein the instructions, when executed, cause the machine to determine the position of the tube by detecting operation of the motor and detecting a lack of rotation of the tube.

21. The tangible computer readable storage medium of claim 20 , wherein the instructions, when executed, cause the machine to detect the lack of rotation of the tube using a gravitational sensor.
