Title: Method and apparatus for implementing an extensible authentication mechanism in a web application server
Inventor: PANG ROBERT
IPC: G06F21/41
Filed: 1998-10-29
Abstract: A highly scalable, flexible, and extensible mechanism is provided for authenticating a request from a client. In a preferred embodiment, the invention comprises an authentication engine, an authentication host, a plurality of providers coupled to the host which implement selected authentification schemes, and a machine independent communication mechanism which enables the various components to communicate with each other irregardless of the machine each component resides on. The communication mechanism enables the invention to be distributed, which in turn, makes the invention highly scalable. In operation, the authentication engine receives a request having associated therewith a protect string. The protect string specifies the authentication scheme or schemes that need to be implemented for that request.  The authentication engine parses the protect string into one or more provider requests, and sends the requests to the authentication host.  In response, the host forwards the requests to the appropriate providers for processing. The results of the providers' processing are sent back to the authentication engine, which then processes the results according to the protect string to determine whether the request has been authenticated. With the present invention, it is possible to add providers to the system, or to substitute a new provider for an existing provider, without changing or recompiling any other component in the system.  It is also possible to change the authentication schemes associated with a request by simply changing the protect string. These aspects of the invention make it possible to change implementation at deployment time, as opposed to compile time. This makes the invention highly flexible and extensible.

Title: Method and apparatus for making absolute range measurements
Inventor: KEY WILLIAM S
IPC: G01S17/32
Filed: 1999-01-14
Abstract: The invention relates to a method and apparatus for making absolute distance or ranging measurements using Fresnel diffraction. The invention employs a source of electromagnetic radiation having a known wavelength or wavelength distribution, which sends a beam of electromagnetic radiation through an object which causes it to be split (hereinafter referred to as a "beamsplitter") (22), and then to a target (18). The beam is reflected from the target onto a screen containing an aperture spaced a known distance from the beamsplitter (22). The aperture is sized so as to produce a Fresnel diffraction pattern. A portion of the beam travels through the aperture to a detector, spaced a known distance from the screen. The detector defects the central intensity of the beam. The distance from the object which causes the beam to be split to the target can then be calculated based upon the known wavelength, aperture radius, beam intensity, and distance from the detector to the screen (26). Several apparatus embodiments are disclosed for practicing the method embodiments of the present invention.
