Abstract: A security system includes a central server module designed to interface with one or more portable client modules. The server module manages access information to be sent to the client modules. The client module is a portable device designed to be carried by an authorized user and has a wireless interface that allows communication with the server module. When a user wishes to obtain an access code at a given time, the user logs into the server module via the client module. The central server verifies that the user is authorized to receive the access code for that particular time and securely transmits the access code to the client module. By transmitting access codes over a secure wireless system, the invention eliminates the need for a separate human operator to provide the access codes to the user for opening a lock.

Abstract: A method for recognizing geometric shapes in an image using fuzzy logic. The method includes determining an edge in the image and a gradient of the edge. The gradient is corrected by virtue of a first fuzzy logic process, and the number of points that belong to the curve are determined by virtue of a second fuzzy logic process. A fuzzy device for the recognition of geometric shapes in images that implementing the method includes an edge detector, a fuzzy gradient corrector to correct the gradient, and a fuzzy vote attributor to determine the number of points that belong to the curve.
