Abstract: A method and system for process expression and resolution including a general method of direct association is described. A first language structure including a named result reference which is a destination for a result string for a directly associated correspondingly named resultant is provided. In addition, a second language structure including a result link is provided. A first end of the result link is located within a formal list of a definition. A second end of the result link is directly associated by list position and is located within an actual list of an invocation. A third language structure including the resultant is provided. The resultant is associated with one or more language elements, including: the correspondingly named result reference and/or the correspondingly named result link. A resolution mechanism replaces the named result reference associated with the correspondingly named resultant with the resultant result string such that a language expression is resolved.

Abstract: A method and system for process expression and resolution is described. A first language structure comprising a possibility expression having at least one definition which is inherently and generally concurrent is provided. Further, a second language structure comprising an actuality expression including a fully formed input data name to be resolved is provided. Furthermore, a third language structure comprising an active expression initially having at least one invocation, the invocation comprising an association with a particular definition and the fully formed input data name of the actuality expression is provided. Subsequently, the process of resolving invocations begins in the active expression with fully formed input data names in relation to their associated definition to produce at least one or both of the following: (1) an invocation with a fully formed input data name and (2) a result data name.

Abstract: A logic system, which is capable of logical expression comprising processing members interconnected by transmission elements, wherein the processing member resolves at least two or more input allowed values to one result allowed value, allowed values including one or more data values and one or more non-data values, at least one non-data value being a null value, the processing member changing its result value to a data value only when all of its presented input values are valid and changing its result value to a NULL value only when all of its presented input values are NULL values.

Abstract: A data projection system in which a data projector having a data display memory associated therewith projects images to a viewing screen. The system includes a curved or nonplanar viewing screen and computer software effective to provide viewing fidelity by compensating for inaccuracies of the viewing screen.

Abstract: Methods and apparatus are provided for driving a vehicle from a remote control station achieving tele-operation of the vehicle. A television sensor mounted on the vehicle provides video image information which is reduced in bandwidth by a factor of approximately 1000:1 for transmission by narrow band RF data link to a remote control station. The large bandwidth reduction is accomplished by first sampling the video output of the sensor at a reduced frame rate and then compressing the data further by standard data compression techniques. Vehicle position and attitude data which may be derived from the vehicle's on board inertial reference unit are also transmitted via narrow band data link to the control station.

Abstract: The disclosure relates to a computer controlled imaging system involving a digital image processing and display system which has the ability to compose and construct a display scene from a library of images with sufficient processing speed to permit real-time or near real time analysis of the images by a human operator or a hardware/software equivalent thereof. An unique method of mapping a digital input image to a viewing plane in both linear and perspective modes is disclosed.

Abstract: The disclosure relates generally to a computer generated synthesized imaging system. More particularly, the invention relates to a method and apparatus for providing fast access to a two axis memory wherein consecutive data elements in both row and column orientation of a data set represented as a matrix may be obtained at a rate faster than the access time of memory elements utilized. A speed-up of access speed by a factor N may be achieved, where N is a power of 2 (2, 4, 8, 16 . . . ). The memory elements are organized in N independently addressable banks of data memories. The matrix oriented data is mapped into these N banks such that any N contiguous data elements of any row or any column reside in different memory banks. Any N contiguous data elements of any row or column may then be accessed within the access time of any one memory bank. The N contiguous data elements may then be read from memory in a single memory cycle.

Abstract: A method and apparatus relating to the real time automatic detection and classification of characteristic type surface imperfections occurring on the surfaces of material of interest such as moving hot metal slabs produced by a continuous steel caster. A data camera transversely scans continuous lines of such a surface to sense light intensities of scanned pixels and generates corresponding voltage values. The voltage values are converted to corresponding digital values to form a digital image of the surface which is subsequently processed to form an edge-enhanced image having scan lines characterized by intervals corresponding to the edges of the image. The edge-enhanced image is thresholded to segment out the edges and objects formed by the edges are segmented out by interval matching and bin tracking. Features of the objects are derived and such features are utilized to classify the objects into characteristic type surface imperfections.
