    Abstract: Systems and methods for performing relative object localization using a local positioning system. The process in accordance with one embodiment solves the problem of determining the location (i.e., the position and orientation) of an object relative to a previous location of the object, or relative to another object, without the need for known 3-D data point positions in the environment. The process in accordance with another embodiment solves the problem of determining the location of the measurement instrument relative to a previous location of the measurement instrument using visible feature points on a target object as a reference, again without the need for known 3-D data point positions. The process in accordance with a further embodiment is capable of determining the locations of multiple objects relative to each other.

    Abstract: Described herein is an apparatus, for shielding light generated by a laser during non-destructive inspection of an object. The apparatus includes a light shield at least partially enveloping the laser and defining a first opening through which light generated by the laser passes from the laser to the object. The light shield is opaque and includes at least one first biasing mechanism. The apparatus also includes at least one first light seal coupled to the light shield about the first opening of the light shield. The at least one first biasing mechanism is configured to urge resilient deformation of the at least one first light seal against the object. When the at least one first light seal is resiliently deformed against the object, light generated by the laser is constrained within a light containment space defined between the light shield, the at least one first light seal, and the object.

    Abstract: Wing-to-fuselage joints and aircraft including the same. An aircraft includes a fuselage with an outer fuselage skin that at least partially defines an outer surface of the fuselage and a wing assembly operably coupled to the fuselage via a wing-to-fuselage joint. The wing assembly includes a left wing region with a lower left-wing-region skin and an upper left-wing-region skin, a right wing region with a lower right-wing-region skin and an upper right-wing-region skin, and a center wing region with a lower center-wing-region skin. The outer fuselage skin is coextensive with the lower center-wing-region skin.

    Abstract: Systems and methods for automating robotic end effector alignment using real-time data from multiple distance sensors to control relative translational and rotational motion. In accordance with one embodiment, the alignment process involves computation of offset distance and rotational angles to guide a robotic end effector to a desired location relative to a target object. The relative alignment process enables the development of robotic motion path planning applications that minimize on-line and off-line motion path script creation, resulting in an easier-to-use robotic application. A relative alignment process with an independent (off-board) method for target object coordinate system registration can be used. One example implementation uses a finite-state machine configuration to control a holonomic motion robotic platform with rotational end effector used for grid-based scan acquisition for non-destructive inspection.

    Abstract: Systems and methods that provide a framework for location tracking of a movable target component or device (e.g., an automated device or a hand-operated device) to accurately cover an area of interest along a specified path or in a specified region. Grid patterns are projected onto a surface of a workpiece or a part. The projected grid lines may be straight or curved. Straight grid lines can be parallel or intersecting. The grid pattern may include a path to be followed. The lines of the projected grid pattern are detected by a grid detection sensor which is mounted onboard the movable target component or device. Information from the grid detection sensor is fed to a location mapping program. The systems and methods also enable navigation for use in automated and autonomous manufacturing and maintenance operations, as well as other tracking-based applications.

    Abstract: An extended-reach tool system may include a gimbal positioned adjacent a surface opening; an extended-reach arm having a tool and engaging the gimbal; a sensor system for measuring a position of the arm relative to the gimbal and a position and spatial orientation of the tool relative to the opening; a computer control that converts one or both of the rotational and linear measurements from the sensor system into spatial location representations for virtual representations of 3-D models of the workpiece and tool, determines a position and orientation of the tool relative to the opening and workpiece, and adjusts the virtual representations of the 3-D models of the workpiece and tool as the arm and tool move relative to the workpiece, representing a real-time orientation of the tool relative to the workpiece; and a display for displaying the virtual representations of the 3-D models of the workpiece and tool.

    Abstract: Method and apparatus for detecting defects in a laminate of uncured, compacted composite sheets. After a number of plies of composite sheets are arranged and compacted, a burst of heat energy is applied to a top surface of the laminate and a digital thermographic camera captures images of the top surface. A computer processor measures heat characteristics of the top surface to identify regions of the top surface with different heat characteristics. Such different areas are identified as regions that include a defect. The defect regions can be repaired by applying additional compaction and/or by removing at least a portion of some layers, removing any foreign object debris, replacing the layers, and compacting the replaced layers. After any defects are addressed, the laminate is cured.
