Intelligent automated motorized window treatment with increased energy efficiency and method of using same

A window treatment system comprising:

• a headrail housing a motor, a first power source configured to power the motor, and a receiver operable to receive wirelessly transmitted power to charge the first power source;
• a window shade fabric extending between a first terminus and a spaced apart second terminus, wherein the first terminus is affixed inside the headrail and is raised and lowered by the motor;
• a bottom rail attached to the second terminus of the shade fabric, the bottom rail comprising an inertial sensor, a second power source, and a transmitter,
• wherein the transmitter is operable to:
• upon determining that the bottom rail is within a predetermined distance of the headrail, wirelessly transmit power from the second power source to the receiver in the headrail, using a first wireless power transmission technique, and upon determining that the bottom rail is not within the predetermined distance of the headrail, wirelessly transmit power from the second power source to the receiver in the headrail using a second wireless power transmission technique, wherein the first wireless power transmission technique is different than the second wireless power transmission technique;
• a control button being coupled to the inertial sensor and the motor, the control button being operable for:
• controlling the motor to lower the bottom rail along a downward path to an end position;
• monitoring, via the inertial sensor, for obstructions in the downward path;
• in response to detecting an obstruction, controlling the motor to raise the bottom rail a predefined distance;
• and
• controlling the motor to re-attempt to lower the bottom rail to the predefined end position while monitoring, via the inertial sensor, for obstructions in the downward path.
