    Abstract: A motor calibration system and method for a motor having a rotor and a stator and comprising at least one phase. The system further comprises at least one position detector adapted to detect a position of the rotor with respect to the stator and generate a feedback signal and a controller adapted to perform a calibration sequence to calibrate to motor. Wherein the controller calibrates the motor by driving at least one motor phase with a motor control signal at a predetermined maximum amplitude value in a first direction with substantially no load applied on the motor, receiving a feedback signal from the at least one position detector, and determining a first calibration angle shift by measuring a difference between at least the motor control signal and the feedback signal of the at least one motor phase. The controller accounts for the first calibration angle shift when driving the motor in the first direction during normal operation. According to one embodiment, the controller may determine a second calibration angle shift for a second direction in a similar manner. According to another embodiment, the may determine the second calibration angle shift using a transformation function and a predetermined angle shift sum constant.

    Abstract: Systems, devices, and methods for automatically forming a wireless personal area network (PAN) comprising a network auto-formation (NAF) process. At least one network coordinating device initializes a PAN and transmits at least one beacon comprising PAN information. A network joining device performs a number of scan/listen cycles by actively scanning a plurality of wireless channels for PANs by masking out channels in a scan channel mask, and listening for beacons on channels in a listen channel list. The scan channel mask and the listen channel list are updated during each scan/listen cycle. The scan channel mask may comprise channels containing desired PANs, non-desired PANs, and channels on which beacons were heard. The listen channel list may comprise channels containing desired PANs and channels on which beacons were heard. The NAF process further comprises receiving PAN information included in heard beacons and attempting to join the best network based on the PAN information.

    Abstract: A motorized window treatment configure for automatically determining and reporting the tilt level of a motorized window treatment. The motorized window treatment comprises a window covering material, a motor configured for moving the window covering material from an opened position to a closed position, an accelerometer configured for measuring gravitational forces, and a controller configured for reporting the tilt level of the motorized window treatment. Particularly, the controller receives gravitational force measurements from the accelerometer, determines a tilt level of the motorized window treatment using the gravitational force measurements, compares the tilt level to a first threshold value, and issues an error signal when the tilt level exceeds the first threshold value.
