1. A non-contact, automatic door hinge operator system that both opens and closes a door attached to an adjacent wall with hinges, the door hinge operator system comprising:
A spool motor mechanism mounted onto the wall adjacent a hinge edge side of the door, the spool motor mechanism having a rotating spool portion, the spool motor mechanism adjacent the wall;
A controller which controls the rotation of the spool portion, the controller comprising at least one switch providing electrical current to the spool motor mechanism to rotate the spool portion;
An access point located on the door distally from spool mechanism and adjacent a swinging edge side of the door;
A pull wire having a proximal end wound onto the rotating spool portion and having a distal end extending to the access point on the door;
At least one spring-loaded hinge coupling the door to the adjacent wall;
A coupling means which couples the distal end of the pull wire to the access point of the door, whereby upon receipt of an electrical current by the spool motor from the switch and rotation of the spool portion by the controller, the pull wire causes the door to open and wherein the spring-loaded hinge will close the door as the pull wire unwinds from the spool portion; and
A first smart connect sensor attached to the wall adjacent the door and a second smart connect sensor attached to the door, wherein the first and second smart sensors let the controller know whether the door is open or closed based upon whether the first sensor and the second sensor are in contact.
