Abstract: The flexible door seal device provides for sealing against air leaks around a door and doorway without interfering with door opening and closing. The flexible device is easily installed and removed without need of any tools. Also, the device can be rolled or folded into a compact size for transport and storage as needed. The device is self-retained until removed from a door. Retention is accomplished by way of the pockets disposed at each corner. Ideally, the device may be seamless. The device provides a positive seal by way of the insert and the inner flap and outer flap that overlap any space between a door and a jamb. The outer flap is sufficient to overlap drywall, trim, and other door surrounds.

Abstract: A system (10) and method for matching a set of detected points (26) to a reference constellation (20). A programmable processor (14) receives detected coordinate locations from a sensor (16) and reference coordinate locations from a reference storage device (12). The processor (14) performs a coordinate transformation from the reference coordinate frame to the detected coordinate frame and contructs a table of possible matches. Potential matches are found from the possible matches which have their difference vectors below a predefined threshold. These possible matches are then placed in a match matrix histogram (30) which is further refined to eliminate all but the best matches. The final matching then may be used to find a particular aimpoint (24) in the detected constellation (26).
