A wireless battery-operated window covering assembly is disclosed. The window covering has a head rail in which all the components are housed. These include a battery pack, an interface module including an IR receiver and a manual switch, a processor board including control circuitry, motor, drive gear, and a rotatably mounted reel on which lift cords wind and unwind a collapsible shade. The circuitry allows for dual-mode IR receiver operation and a multi-sensor polling scheme, both of which are configured to prolong battery life. Included among these sensors is a lift cord detector which gauges shade status to control the raising and lowering of the shade, and a rotation sensor which, in conjunction with internal registers and counters keeps track of travel limits and shade position.

[ What is claimed is:] [22.] A battery-powered infrared remote-control motorized lift window treatment assembly comprising:a head rail;a reversible dc motor disposed in the head rail;at least one battery disposed in the head rail and configured to power the reversible dc motor;a window covering operatively coupled to said motor and configured to be selectively raised or lowered by the motor;a manual switch configured to output a manual control signal when said manual switch is activated;a light sensor configured to receive a user-generated infrared light signal from a remote control transmitter;an integrated circuit controller electrically connected to said light sensor, the controller configured to respond to at least two different light signals, the controller configured to cause the reversible dc motor to turn in a first direction in response to first information present in a first light signal, and further configured to cause the reversible dc motor to turn in a second direction in response to second information present in a second light signal, said controller having a plurality of connections including:a ground connection;a voltage supply input;a first position input configured to receive information reflective of either a movement or a position of said window covering;a manual signal input configured to receive said manual control signal from said manual switch;a remote signal input configured to receive an output from said light sensor, said output resulting from a user-generated infrared remote-control signal; andfirst and second motor drive signal outputs, each motor drive signal output configured to output a motor drive signal to energize the motor to turn in one of two directions, in response to either a valid user-generated light signal or a manual control signal. [41.] A method of operating a battery-powered infrared remote-control motorized window treatment assembly having a processor therein, the method comprising:waking up the processor from a sleep state;determining whether either a manual switch has been activated or a user-generated infrared light signal has been sensed;if the manual switch has been activated, checking a last direction of travel of the window covering and moving the window covering in a direction opposite said last direction of travel;if a user-generated infrared light signal has been sensed, moving the window covering in a direction determined solely on information present in said user-generated infrared light signal; andmonitoring a position of said window covering, as the window covering moves.
