Powered panel moving system
First Claim
1. A powered panel moving system for moving a panel, the system comprising:
- a motor having a rotor;
electronic drive means for driving the motor in order to rotate the rotor, wherein the rotor has a rotational output in response to being driven;
mechanical means for moving a panel upon being driven;
coupling means for coupling the rotational output of the rotor to the mechanical means in order drive the mechanical means for the mechanical means to move the panel; and
electronic function means integrated with the electronic drive means for providing additional functionality beyond driving the motor for movement of the panel.

Abstract
A powered panel moving system includes a motor, electronic drive circuitry, a mechanism, a coupler, and electronic function circuitry. The drive circuitry drives a rotor of the motor. The coupler couples rotational output of the rotor to the mechanism to drive the mechanism in order to move the panel. The function circuitry is integrated with the drive circuitry for providing additional functionality beyond driving the motor for panel movement. The drive circuitry includes a current sensor for determining rotor position based on motor current, a back emf sensor for determining rotor position based on back emf of the motor, and an impedance sensor for determining rotor position based on motor impedance. The function circuitry may include an analyzer to determine presence of an obstruction to the motion of the panel based on at least one of the rotor position, the motor current, and the back emf of the motor.
