| 20090086199 | METHOD INVOLVING A POINTING INSTRUMENT AND A TARGET OBJECT - 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. | 04-02-2009 |
| 20090099709 | ROBOTIC VEHICLE APPARATUS AND METHOD - A method for forming a robotic vehicle. The method may involve forming a body and arranging a plurality of movable legs to project from the body for propelling the body over a surface. An actuator may be carried by the body to selectively engage and disengage different ones of the movable legs to cause a motion of the body, and thus the robotic vehicle, to travel over the surface. | 04-16-2009 |
| 20090222149 | SYSTEM AND METHOD FOR CONTROLLING SWARM OF REMOTE UNMANNED VEHICLES THROUGH HUMAN GESTURES - A method is disclosed for controlling at least one remotely operated unmanned object. The method may involve defining a plurality of body movements of an operator that correspond to a plurality of operating commands for the unmanned object. Body movements of the operator may be sensed to generate the operating commands. Wireless signals may be transmitted to the unmanned object that correspond to the operating commands that control operation of the unmanned object. | 09-03-2009 |
| 20100085437 | METHOD AND SYSTEM INVOLVING CONTROLLING A VIDEO CAMERA TO TRACK A MOVABLE TARGET OBJECT - 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. | 04-08-2010 |
| 20100102980 | Hand-Held Positioning Interface for Spatial Query - 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. | 04-29-2010 |
| 20100153051 | Locating A Component Underneath A Surface Of A Target Object And Locating An Access Panel For Accessing The Component - A first method locates a component positioned underneath a surface of a target object using a pointing instrument, wherein a position of the component in the target object coordinate system is known. The first method includes calculating an orientation of the aim point axis of the instrument in the instrument coordinate system for the aim point axis of the instrument to be aligned with the component using at least an inverse calibration matrix, the position of the component in the target object coordinate system, and inverse kinematics of the instrument. The first method also includes rotating the aim point axis of the instrument to the calculated orientation. Second and third methods also are described for locating an access panel for accessing the component and/or maintenance zones in which the component resides. | 06-17-2010 |
| 20100202868 | APPARATUS AND METHODS FOR LIFTING AND LOWERING VERTICALLY MOUNTED DEVICES - A lifting and lowering apparatus may include: at least one cable, at least one pulley connected to the at least one cable, at least one drive member connected to the at least one cable for driving the at least one cable in at least one direction, a moveable payload attachment member for attaching to a payload to be at least one of lifted and lowered, an attachment member guide attached to the moveable payload attachment member, and an alignment guide for positioning at a position. The moveable payload attachment member may be at least one of lifted and lowered by the at least one cable. Both the attachment member guide and the alignment guide may be shaped to force the attachment member guide into a pre-determined mating position and orientation against the alignment guide at the position. | 08-12-2010 |
| 20110149266 | Position and Orientation Determination Using Movement Data - Position determining systems and methods are provided. A particular portable device includes a calibration component to communicate with a local positioning system to determine an initial position and orientation of the portable device within a local coordinate system associated with a target structure. The portable device also includes at least one movement sensor to detect movement of the portable device. The portable device further includes a processor to determine a measured position and orientation of the portable device based on the initial position and orientation of the portable device within the local coordinate system and based on the detected movement of the portable device. | 06-23-2011 |
