    Abstract: Methods are described for controlling orientation of an aim point axis of a video camera having an instrument coordinate system to track a point of interest on a movable target object and calculating positions of the point of interest in a local coordinate system in which the target object is moving. The methods include measuring pan and tilt angles of the aim point axis and distance substantially along the aim point axis and calculating a calibration matrix which transforms a position defined in the instrument coordinate system to a position defined in the local coordinate system. A system is described including an instrument and at least one computer, wherein the instrument includes a video camera and a range finder, and wherein the video camera includes an aim point axis having an adjustable orientation. In one example, the target object is adapted to move on and inspect an airplane surface.

    Abstract: A system and method for determining the position and orientation of a handheld device relative to a known object is presented. The system comprises a handheld device having an inertial measurement unit and a sighting device, such as a laser pointer, that are used to determine the position of the handheld device relative to a target object, such as a structure, aircraft, or vehicle. The method comprises calibrating a handheld device to find the current location of the handheld device relative to a target object, tracking the movement of the handheld device using an inertial measurement unit, and presenting an updated position of the handheld device relative to a target object.

    Abstract: A system comprising a multi-functional boom subsystem integrated with a holonomic-motion boom base platform. The boom base platform may comprise: Mecanum wheels with independently controlled motors; a pair of sub-platforms coupled by a roll-axis pivot to maintain four-wheel contact with the ground surface; and twist reduction mechanisms to minimize any yaw-axis twisting torque exerted on the roll-axis pivot. A computer with motion control software may be embedded on the boom base platform. The motion control function can be integrated with a real-time tracking system. The motion control computer may have multiple platform motion control modes: (1) a path following mode in which the boom base platform matches the motion path of the surface crawler (i.e., integration with crawler control); (2) a reactive mode in which the boom base platform moves based on the pan and tilt angles of the boom arm; and (3) a collision avoidance mode using sensors distributed around the perimeter of the boom base platform to detect obstacles

    Abstract: A system and methods for location authentication are presented. A subset of demodulated server received navigation signals are selected synchronized to client bit frames to provide synchronized server bit frames. A function of the synchronized server bit frames is computed to provide a server signature set. A client signature set and the server signature set are compared to provide a comparison result, and a location of a client device is authenticated based on the comparison result.

    Abstract: A self-contained, holonomic motion tracking solution for supplementing the acquisition of inspection information on the surface of a structure, thereby enabling the real-time production of two-dimensional images from hand-held and automated scanning by holonomic-motion of non-destructive inspection (NDI) sensor units (e.g., NDI probes). The systems and methods disclosed enable precise tracking of the position and orientation of a holonomic-motion NDI sensor unit (hand-held or automated) and conversion of the acquired tracking data into encoder pulse signals for processing by a NDI scanning system.
