Methods and apparatus for controlling architectural opening coverings in more than one mode

1. An apparatus for operating a covering of an architectural covering, the apparatus comprising:

a clutch to mechanically disengage a motor from operating a covering of an architectural covering when the motor is not in use;

a manual control to move the covering of the architectural covering while the motor is disengaged; and

a braking element to resist movement of a drive element of the covering when the motor is mechanically disengaged.

2. The apparatus of claim 1 , further including a motor controller to:

cause a cam follower of the clutch to move, in a first direction, to engage the motor with the drive element to move the covering; and

cause the cam follower to move, in a second direction opposite the first direction, to disengage the motor.

3. The apparatus of claim 2 , wherein the motor controller is structured to cause the cam follower of the clutch to further move in the second direction to engage the motor to move the drive element in the second direction.

4. The apparatus of claim 2 , wherein the clutch includes a drive gear coupled to the drive element.

5. The apparatus of claim 1 , wherein the manual control is configured to enable a user to move the covering while the motor is disengaged, wherein a force applied by at least one of the manual control or the motor overcomes the resistance provided by the braking element.

6. The apparatus of claim 1 , further including a covering position determiner to track a position of the covering while the motor is disengaged.

7. The apparatus of claim 6 , wherein the covering position determiner includes an encoder.

8. The apparatus of claim 1 , further including a motor position determiner to track a position of the motor while the clutch disengages the motor.

9. The apparatus of claim 8 , wherein the braking element is structured to resist movement of the drive element while the clutch disengages the motor.

10. The apparatus of claim 1 , further including:

a motor position determiner to monitor movement of the motor; and

a motor controller to:

cause an elongated member of the clutch to move, in a first direction, to engage the motor with the drive element by coupling a keyed surface of a cam follower to a mating keyed surface of a drive gear attached to the drive element;

cause the elongated member to move, in a second direction opposite the first direction, to disengage the motor by decoupling the keyed surface of the cam follower from the mating keyed surface of the drive gear; and

cause the elongated member to stop movement after a threshold has been met for disengaging the motor.

11. The apparatus of claim 10 , wherein the elongated member is coupled to the motor.

12. The apparatus of claim 10 , wherein the cam follower moves across a cammed surface of the elongated member.

13. The apparatus of claim 10 , further including a covering position determiner to:

monitor a position of the covering during movement of the covering by the motor and during manual movement of the covering; and

determine when the covering is at a limit, wherein the motor controller is to cause the motor to reverse movement to disengage the drive element when the covering of the architectural covering reaches the limit.

14. The apparatus of claim 10 , wherein the motor controller is structured to cause movement of the elongated member in the first direction to cause the cam follower to reach a stop causing the cam follower to move with movement of the elongated member.

15. The apparatus of claim 14 , wherein the motor controller is structured to cause movement of the elongated member in the first direction to cause the cam follower to be moved toward the drive gear to couple the mating keyed surface of the drive gear with the keyed surface of the cam follower.

16. The apparatus of claim 15 , wherein the motor controller is structured to cause movement of the elongated member in the second direction to allow the cam follower to move away from the drive gear to decouple the keyed surface of the cam follower from the mating keyed surface of the drive gear.

17. The apparatus of claim 10 , wherein the braking element is structured to resist movement of the drive element while the motor is disengaging from the drive element.

18. The apparatus of claim 1 , wherein the clutch is structured to disengage a shaft of the motor from the drive element.

19. The apparatus of claim 18 , wherein the clutch is structured to disengage the motor from the drive element when a direction of rotation of the motor is reversed at an end of a motorized operation.

20. The apparatus of claim 1 , wherein the manual control is structured to rotate the drive element to move the covering while the motor is disengaged.

21. A method for operating a covering of an architectural covering, the method comprising:

tracking a first position of a covering by monitoring a covering position encoder;

disengaging a motor from operating the covering to allow manual operation of the covering of the architectural covering when the motor is not in use; and

tracking a second position of the motor via a motor encoder while the motor disengages.

22. The method of claim 21 , further including:

moving, in a first direction, a cam follower of a clutch to engage the motor with a drive element to move the covering; and

moving, in a second direction opposite the first direction, the cam follower to disengage the motor from the drive element.

23. A tangible computer readable medium comprising instructions that, when executed, cause a machine to at least:

track a first position of a covering by monitoring a covering position encoder;

disengage a motor to allow manual operation of the covering when the motor is not in use; and

track a second position of the motor via a motor encoder while the motor disengages.
