Title: Method and apparatus for pattern classification using distributed adaptive fuzzy windows
Inventor: HUANG YEE-WEI
IPC: G06F15/18
Filed: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates generally to methods and apparatus for pattern classification, and, in particular, to pattern classification methods and apparatus which distribute the classification criteria across an artificial neural network.  The classification criteria for a pattern class are stored distributively in the neural network in two aspects. First, they manifest themselves as one or more (quantum) levels of templates, each of which represents a fuzzily unique perspective of the pattern class.  Second, the templates at each level are represented by a set of fuzzy windows, each of which defines a classification criterion of a corresponding feature of the pattern class.  The resultant artificial neural network adapts to produce a "match metric" which indicates the degree of similarity between a new input pattern and a pattern stored distributively in the neural network in the form of the plurality of fuzzy windows.

Title: Corrosion Condition Evaluation and Corrosion Protection of Unbonded Post-Tension Cables in Concrete Structures
Inventor: VANDER VELDE HENRY
IPC: G01N1/22
Filed: 1993-04-14
Abstract: There is disclosed a method and apparatus for the corrosion condition evaluation of unbonded prestressing elements in post-tension concrete structures.  The method involves locating a prestressing element in the structure and providing at least two openings in the structure at positions along the length of the element.  One of the openings is an inlet port and the other is an outlet port, each of the ports permitting communication with the gaseous environment within a conduit surrounding the prestressing element.  The gaseous environment is accessed through the outlet port by extracting a sample of gas therethrough.  The sample is then measured to determine its humidity and thereby evaluate the corrosion condition of the prestressing element between the inlet port and the outlet port.  A method and apparatus is also provided for the on-site corrosion protection of unbonded prestressing elements whereby the gaseous environments within the conduits are cyclically pressurized with a dry gas.  The protection method may also include programmable control of the dry gas pressurization and feedback of the humidity levels in the conduits for adjusting the parameters of cyclical pressurization so as to maintain a predetermined maximum humidity value in the gaseous environments associated with the prestressing elements of the structure.

Abstract: An adjustable frame for carrying vehicles between elongate upright sides includes, on each side, a forward end and a rearward end, each end including an upper and lower rail section joined by elongate brace members, where the respective ends are separated from one another and a length-adjusting insert is carried between such ends to selectively permit adjustment of the posi-tion of the forward end relative to the rearward end while maintaining the ends in end-to-end alignment.  On each side of the frame, preferably at least one of the upper rail sections has an end portion defining an open-ended hollow tube extending lengthwise of that side within which an elongate arm of the length-adjusting insert is slidably moveable so that structures on the outside surfaces of the rail sections will not interfere with length adjustment.  Preferably, on each side, the upper and lower rail sections of the respective ends together define longitudinally aligned upper and lower pairs of open-ended tubes in which are slidably received an upper and lower pair of arms of the length-adjusting insert, thereby permitting the insert to remain perma-nently in position on each side regardless of the length selected.  Preferably, also, the forward and rearward ends of the frame are lockable to the arms of the insert while keeping the insert centered longitudinally with respect to each side.

Title: Low nox burner
Inventor: LANG JERRY M
IPC: F23D14/46
Filed: 1992-10-29
Abstract: A low NOx burner combustion system (10) which may be adjusted for optimum burn rates, temperature and oxygen levels. The burner (10) incorpo-rates a plurality of gas nozzles (38) which individually inspirate a portion of the combustion air and a spin vane dif-fuser (28) to rotate and mix the gases within the primary combustion zone (24). The diffuser (28) is axially adjus-table in order to vary the distance be-tween the vane and the first combustion zone (24) while the blades (30) of the diffuser (28) can be angularly adjusted to optimize the rotation and mix of the gases. Air for combustion is supplied through primary (20), secondary (42) and tertiary (54) passages to create dis-tinct combustion zones for complete combustion. The flow rate of the com-bustion air is controlled through a dam-per (26) in accordance with the burn characteristics. The angular and axial position of the diffuser and the damper control of combustion air can be auto-matically adjusted throughout the firing range of the burner (10) in response to demand levels. In order to convert existing burners to the efficient low NOx burner of the present invention the primary air chamber may be retrofit into the main burn-er chamber. In a further embodiment, flue gas is recirculated and mixed directly with combustion fuel prior to combustion for reduced emission levels.
