A method implemented in an architectural covering. The method includes transmitting a first drive instruction to drive a motor in a first direction while the motor is in an engaged state, wherein driving the motor in the first direction causes the covering to move. The method further includes determining the motor is to terminate an operation. The method further includes transmitting a termination instruction to the motor to terminate the operation. The method further includes determining a first position of the motor. The method further includes transmitting a second drive instruction to drive the motor in a second direction opposite the first direction from the first position to a second position, causing the motor to enter a disengaged state, wherein driving the motor in the second direction does not cause the covering to move.

Example architectural opening coverings powered by rotary motors are described. An example an architectural covering comprises a rotatable member, a covering mounted to said rotatable member, a motor to rotate a drive shaft, and a drive shaft coupling structured to: couple the drive shaft to said rotatable member to rotate said rotatable member to raise said covering when said motor is energized to rotate the drive shaft in a first direction, and substantially prevent the drive shaft from applying torque to said rotatable member when said motor is energized to rotate the drive shaft in a second direction to lower said covering.

The present invention advantageously provides a motorized roller shade that includes a shade tube, a motor/controller unit and a power supply unit. The motor/controller unit is disposed within the shade tube, and includes a bearing, rotatably coupled to a support shaft, and a DC gear motor. The output shaft of the DC gear motor is coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket.

A dual control architectural covering is disclosed. A dual control architectural covering includes a clutch to disengage a motor when the motor is not in use. The dual control architectural covering further includes a manual control to move the covering of the architectural opening while the motor is disengaged. The dual control architectural covering further includes a braking element to resist movement of a drive element of the covering when the motor is disengaged.
