PROBLEM TO BE SOLVED: To provide a method and a device for determining if generation of inconsistencies in fiber placement are related to automatic cutter operations used for cutting tows in a device for automatically placing tows of a composite material on a form. SOLUTION: The operations of the tow cutters 34 in an automatic fiber placement machine 20 are monitored to determine if consistencies in the fiber placement are related to the cutter operations. A machine vision system 39 detects inconsistencies in tow placement, and timing signals for representing the actuation of the cutters are generated. The timing signals are correlated with recorded images of the placed tows 22 to determine if the inconsistencies in the tow placement are related to the cutter operations.

PROBLEM TO BE SOLVED: To provide a system and a method enabling repair of a defect manually or without operator intervention by automatic return of a material stationing machine to a defective part. SOLUTION: The method includes a step to electronically access position data specifying a place of defect on a composite structure, and a step to make the material stationing machine automatically returning to the place of defect specified by the position data. The method can also include a step to make the material stationing machine automatically arranging sufficient material to repair the defect in the place of defect. Alternatively, the operator may manually repair the defect in the place of defect after the material stationing machine has automatically returned to the place of defect. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide an improved system for identifying defects in a complex structure, by providing a light source so that defects, such as dark defects at a dark background and/or bright defects at a bright background, can be identified by capturing an image at an illuminated part in the complex structure. SOLUTION: The improved system for identifying defects in the complex structure can include a reflection surface, a dispersive element, and a plurality of and/or movable light sources and/or a camera for capturing the most accurate image for processing even at a curved region or a region having an external form, or at any region of the complex structure. As a result, by the system, an operator can rapidly identify or correct structural marks for affecting the integrity of the complex structure, or defects for causing unconformity.

PROBLEM TO BE SOLVED: To provide a system and method for determining a cumulative tow gap width. SOLUTION: The system includes an in-process vision system having at least one camera adapted to record images of a composite material and a data analysis computer adapted to communicating with the in-process vision system and receiving image data from the in-process vision system. The data analysis computer may be adapted to calculate the cumulative gap width of tow gaps in the composite material. A user interface may communicate with the data analysis computer and may be adapted to receive data analysis results from the data analysis computer. The method for determining cumulative tow width gap of tow gaps in a composite structure is also disclosed. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method and system for an armor system. SOLUTION: The system includes a first face sheet and a shaped preform 100 extending from the first face sheet. The preform 100 includes a first edge 106 proximate the first face sheet and a sidewall 110 extending from the first edge 106 to a flange 112 extending substantially perpendicularly from the sidewall 110. The system includes a tile of armor material complementarily-shaped to fit within the area circumscribed by the preform 100. The tile is positioned within the preform 100 such that at least a portion of the tile is between the first face sheet and the flange. The system includes a second face sheet covering the preform 100 and the tile on a side opposite from the first face sheet. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method and a system for determining cumulative foreign object characteristics during manufacturing of a composite structure. SOLUTION: Images of sequential segments of the composite structure can be recorded during placement of the composite structure. The recorded images are analyzed for detecting foreign objects on the composite structure. The cumulative foreign object characteristics of the foreign objects detected on the composite structure can be determined, and the cumulative foreign object index can be provided to a user. Thereby, the method and the system for determining the cumulative foreign object characteristics during manufacturing of the composite structure can be provided. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a system and method for identifying a defect, a foreign matter and debris (FOD), when manufacturing composite structure. SOLUTION: This system includes at least one light source positioned to emit light beams for illuminating one portion of the composite structure by bright field illumination, and for illuminating another portion of the composite structure by dark field illumination. The bright field illumination is reflected by the defect in the composite structure differently from a nondefective portion out of the composite structure. The dark field illumination is reflected by the FOD in the composite structure differently from a surface having no FOD out of the composite structure. The system includes also at least one camera for receiving images of the illuminated portions of the composite structure. The images received by the camera are processed by a processor, and then the processor outputs a response for identifying the defect, the foreign matter and the debris, based on the images.
