Door lock and operation mechanism
First Claim
1. A door locking apparatus comprising:
- a door opening device supported on a door, the door opening device having a user verification system for receiving input data comprising;
a memory for storing comparison data;
a processor for comparing received input data with the stored comparison data and producing an output instruction;
a locking mechanism controlled according to the output instruction from the processor;
a door latch controlled by the locking mechanism, the door latch having a locked position and an unlocked position;
a remote power source separate from the door opening device for providing electrical power to the operate the locking mechanism and user verification system; and
an image capture device communicating with at least one of a controller and the processorfor acquiring an image of a person using or attempting to use the door locking apparatus.

Abstract
A locking doorknob which recognizes a fingerprint, in which the detecting sensor of a fingerprint is installed on the spot of the doorknob that a thumb or other fingers are placed naturally as the door is being opened. The locking doorknob is an electromechanical device which can be powered by a remote electrical power system, specifically by electromagnetic induction through the door latch and strike plate. During operation, as soon as a user grasps the doorknob, a fingerprint is measured and searched and, if the fingerprint corresponds to a fingerprint previously input, the door is unlocked and the doorknob can be turned to open the door. An image capture device may also be combined with the doorknob to facilitate recognition of persons using or attempting to use the doorknob. In this way, fingerprint recognition, continuous real time security and opening of the door are performed at the same time.

18. A method of operating a door locking apparatus comprising the steps of:
-
providing an electrically operated door opening device supported in a door;
storing user comparison data in an electronic memory of a user verification system in the door opening device;
inputting user data to the user verification system in the door opening device;
