Abstract:
Situational-awareness controllers and methods to increase situational-awareness for an actor associated with a triggering event are described. An example method includes in response to receiving a notification of a triggering event generated by at least one sensor, a computing device accessing information that includes related to an actor associated with the triggering event. The computing device correlates the information to a compilation of historical information by (i) determining whether the actor's location is associated with one or more safety events stored as part of the compilation of historical information and (ii) determining a risk level of the actor based on whether the one or more associated safety events occurred within a predetermined range of time from the time associated with the triggering event. The computing device generates a command based on a result of the correlating and sends the command to at least one controllable device.
Abstract:
A method and apparatus for performing an operation on a workpiece using a multi-axis compliant end-effector for attachment to a robotic device. The end-effector is positioned at a nominal location of a workpiece feature on which the operation is to be performed. The end-effector is passively aligned with the workpiece feature by contacting the end-effector with the workpiece feature. The operation is performed on the workpiece feature in response to aligning the end effector with the workpiece feature.
Abstract:
Systems and methods for constructing and saving files containing computer-generated image data with associated virtual camera location data during 3-D visualization of an object (e.g., an aircraft). The process tags computer-generated images with virtual camera location and settings information selected by the user while navigating a 3-D visualization of an object. The virtual camera location data in the saved image file can be used later as a way to return the viewpoint to the virtual camera location in the 3-D environment from where the image was taken. For example, these tagged images can later be drag-and-dropped onto the display screen while the 3-D visualization application is running to activate the process of retrieving and displaying a previously selected image. Multiple images can be loaded and then used to determine the relative viewpoint offset between images.
Abstract:
A system is provided that includes a scanner movable relative to seat units and controllable devices each having RFID tags, the scanner configured to obtain a continuum of received signals, a distance sensor configured to determine a relative position of the scanner, a filter configured to disregard outliers and smooth the continuum into respective sets of received signal data, wherein each set of received signal data includes data points having a unique ID and a received signal strength, and wherein a relative time and a relative position are determined for each data point, and a processor configured to determine a relative location of each RFID tag, based on the relative position associated with maximum received signal strength within the set of received signal data, and generate a data file including pairings of seat units and associated controllable devices based on similar relative positions of RFID tags.
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:
An apparatus and method for attaching a crawler vehicle to the surface of an object. The crawler vehicle may comprise a frame, a number of moveable surface-engaging components attached to the frame, a number of actuators, and an electro-permanent magnet. The number of actuators is operable to move the frame with respect to the object when the number of moveable surface-engaging components is in contact with the surface of the object. The electro-permanent magnet is operable to hold the number of moveable surface-engaging components in contact with the surface of the object by a magnetic force between the electro-permanent magnet and the object when the electro-permanent magnet is activated and to remove the magnetic force when the electro-permanent magnet is deactivated to release the number of moveable surface-engaging components from the surface of the object.
Abstract:
A method, system, and apparatus for visually presenting a virtual environment relative to a physical workspace. An output device visually presents a view of the virtual environment to guide a human operator in performing a number of operations within the physical workspace. A mounting structure holds the output device and is movable with at least one degree of freedom relative to the physical workspace. A sensor system measures movement of the output device relative to the physical workspace to generate sensor data. A controller computes a transformation matrix and the set of scale factors to align the virtual environment and the physical workspace. The controller changes the view of virtual environment based on the sensor data to thereby change the view of the virtual environment in correspondence with the movement of the output device relative to the physical workspace.
Abstract:
Systems and methods for high-speed non-destructive inspection of a half- or full-barrel-shaped workpiece, such as a barrel-shaped section of an aircraft fuselage. Such workpieces can be scanned externally using a mobile (e.g., translating) arch gantry system comprising a translatable arch frame disposed outside the fuselage section, a carriage that can travel along a curved track carried by the arch frame, a radially inward-extending telescopic arm having a proximal end fixedly coupled to the carriage, and an NDI sensor unit coupled to a distal end of the telescoping arm. The stiffeners of the fuselage sections can be scanned using a mobile scanner platform disposed inside the fuselage section, which platform comprises a radially outward-extending telescopic arm rotatably coupled to a mobile (e.g., holonomic or linear motion) platform and an NDI sensor unit coupled to a distal end of the telescoping arm. The scan data is matched with position data acquired using any one of a plurality of tracking systems to enable the display of NDI features/flaws on a three-dimensional representation of the workpiece.
Abstract:
An apparatus comprises an inspection vehicle, a sensor system, a positioning system, a controller, and a support system. The inspection vehicle is configured to move on a surface of an object. The sensor system is associated with the inspection vehicle and is configured to generate information about the object when the inspection vehicle is on the surface of the object. The positioning system is configured to determine a location of the inspection vehicle on the object. The controller is configured to control movement of the inspection vehicle using the positioning system and control operation of the sensor system. The support system is connected to the inspection vehicle and is configured to support the inspection vehicle in response to an undesired release of the inspection vehicle from the surface of the object.
Abstract:
An apparatus may include: a support base; and two or more roller wheels, each adjustable in orientation, position, or orientation and position, mounted on the support base and configured to engage with an object in a passive locking configuration. The apparatus may be further configured to disengage from the object in the passive locking configuration. The apparatus may be further configured to lock the object to the apparatus in an active locking configuration. Orientations, positions, or the orientations and positions of the at least two of the two or more roller wheels may be adjustable.
