Method for operating a motorized roller shade
First Claim
1. A method for controlling a motorized shade, the method comprising:
- providing a shade tube extending a length between opposing ends, the shade tube having an exterior surface and at least a partially hollow interior;
providing a shade extending a length from a top end to a bottom end;
operatively connecting the shade to the shade tube;
providing a DC gear motor having a first rotatable shaft;
providing a multi-pole magnet;
operably connecting the multi-pole magnet to the first rotatable shaft;
operatively connecting the DC gear motor to the shade tube;
providing at least one sensor;
positioning the at least one sensor within sensing distance of the multi-pole magnet;
providing a microcontroller operatively connected to the at least one sensor;
detecting a manual movement of the shade using the at least one sensor;
determining a displacement associated with the manual movement by measuring rotation of the first rotatable shaft using magnetic pulses detected by the at least one sensor.

Abstract
An architectural covering is provided. The architectural covering includes: shade material; the shade material operatively connected to a motor unit such that movement of the motor unit causes movement of the shade material; the motor unit comprising a DC motor and a shaft connected to the DC motor; a power supply unit electrically connected to the motor unit; a controller unit electrically connected to the motor unit, the controller unit having a microprocessor; and a rotation detector configured to detect rotation of the motor unit and upon detection of rotation of the motor unit transmit a signal to the microprocessor, wherein the microprocessor of the controller unit is configured to power an encoder unit in response to determination of manual movement of the shade material. A motor and control unit for an architectural covering may be provided.
