Appl. No.:

08/944885

International Classification:

G01M 700

US Classification:

73 1213, 73 1201, 73 1206

Abstract:

A damage detection device is used to detect damage in bonded and laminated composite structures. A tap hammer or tap coin containing an acceleration sensor is connected to a circuit that can measure the width of an impact signal and then display the result. The result correlates to local stiffness of a structure. A method of determining the desired signal width and the method of using the damage detection device, includes tapping a known good region and then tapping a suspect region. Readings from the two areas are used to determine whether the suspect region is within an acceptable range. The circuit determines the desired signal width by measuring from the time the impact signal exceeds a threshold to the time it falls below the threshold.

Abstract:

A first method determines a position of a point of interest on a target object surface in a target object coordinate system using orientation and distance measurements of a pointing instrument in an instrument coordinate system. A second method determines an orientation of a pointing instrument in an instrument coordinate system for the instrument to be aligned with a point of interest on a target object surface having a target object coordinate system, wherein a position of the point of interest in the target object coordinate system is known. A third method controls orientation of a laser beam of a laser in an instrument coordinate system for the laser beam to trace an image on a target object surface having a target object coordinate system, wherein positions of points for the image on the surface of the target object in the target object coordinate system are known.

US Classification:

156285, 156361, 156577, 156185

Abstract:

A ply placement device uses a ply guide to place plies on a curved substrate surface. The ply guide includes a guide surface and a guide edge that are each curved to match the contour of the substrate so that the ply transitions smoothly from its planar form to a curved form as the ply is placed onto the substrate. The ply guide may be flexible or segmented to allow reconfiguration of the guide surfaces to match various substrate contours.

US Classification:

348 25, 3482071, 34820711, 3482083

Abstract:

A local positioning system which includes a video camera, a computer communicating with the video camera and a target object sighted by the video camera and having a target object coordinate system. The computer is adapted to define a relative position and orientation of the video camera with respect to the target object, determine a position and orientation of the video camera in the target object coordinate system, and determine the position of a point of interest in the target object coordinate system. The system can also be used to aim the camera at a previously recorded point of interest on the target object. Contact with, or close proximity to, the target object is not required. A local positioning method is also disclosed.

International Classification:

G06K 9/00

US Classification:

382108

Abstract:

A method and apparatus are used to fit a metallic or composite doubler on an uneven surface. A three dimensional digital map of the gap between the doubler and the uneven surface is generated by digitally scanning the uneven surface. The digital map is then used to fabricate a stack of adhesive plies tailored to substantially fill the gap between the doubler and the uneven surface.
