Abstract: A signal is sent into a first surface of a structure at an angle relative to the first surface of the structure using a transducer array, wherein the structure has a second surface with a portion non-parallel to the first surface. An ultrasound response signal is formed at the portion of the second surface of the structure. The ultrasound response signal is received at the transducer array.

Abstract: A method for inspecting a composite structure includes acquiring an image of the composite structure. The composite structure includes at least a first ply and a second ply adjacent the first ply. The method also includes transforming the image into a binary image, and determining a first boundary line between the first ply and the second ply. The method further includes characterizing an irregularity in the composite structure based at least partially on the first boundary line.

Abstract: A method for monitoring and verifying a manufacturing process performed by an operator on a workpiece in a work area. The method includes positioning one or more cameras in the work area, such that the operator and the workpiece are in a field of view of each of the cameras. The method includes using a computer system configured for controlling the cameras to record and process images of the workpiece and images of operator actions relating to the manufacturing process, all recorded by the cameras during or at completion of each of a plurality of tasks in the manufacturing process to obtain recorded images. The method includes storing the recorded images, comparing the recorded images against a reference image library comprising references images corresponding to each recorded image to detect any differences between the recorded image and the respective corresponding reference image, and generating a data record.
