Abstract:
An autonomous navigation, guidance, and control process for docking and formation flying by utilizing the laser dynamic range imager (LDRI) and key technologies, including fuzzy logic based guidance and control, optical flow calculation (including cross-correlation, phase-correlation, and image differential), software design and implementation, and verification methods. The autonomous navigation, guidance, and control process includes the steps of providing an expected reference position relative to a target; generating a carrier position and attitude relative to said target by a Range and Intensity Images Provider; producing a relative position and attitude error; and producing control commands from said relative position and attitude error for relative motion dynamics.
Abstract:
A miniature in-vivo robotic module to be used for conducting dexterous manipulations on organs and other target entities in a patient's abdominal or peritoneal cavity as part of Natural Orifice Transluminal Endoscopic Surgery (NOTES) is disclosed in this invention. The robotic module is a serial manipulator consisting of seven cylindrical links and six actively controllable rotational degrees of freedom, thereby enabling an end effector equipped with a laparoscopic type instrument to assume a commanded position and orientation within the robot's workspace. After overtube navigation starting from a natural orifice or preexisting wound, the module must be anchored and guided to a designated location along the inner abdominal cavity wall. This is accomplished via magnetic coupling forces between internal embedded magnets and magnets fixed to the end of a different robotic manipulator located external to the patient.
Abstract:
An innovative configuration of Miniaturized Smart Self-calibration EPD for mortar applications, as the azimuth/heading and elevation measurement device. This innovative EPD configuration uses only two FOGs or DTG and accelerometers and it is self-contained. This leads to a new EPD implementation that produces a small and light device with lower cost and adequate accuracy for the small dismounted mortar applications.
Abstract:
A method and system for multi-tracking among independent individuals without a monitoring center, where an individual is a person, a vehicle, or any other property, enables the individuals to be networked in a group and each individual to search and track other individuals of interest. The portable multi-tracking system is also capable of tracking personnel inside a building, where a self-contained positioning device provides continuous carrier's position information. In the open area a GPS (Global Positioning System) unit is activated to provide precision absolute position data which can be blended with the self-contained data to improve the accuracy and robustness of the positioning services. Thus the present invention provides excellent position tracking outside a building.
Abstract:
A Modeling, Design, Analysis, Simulation, and Evaluation (MDASE) aspects of gyrocompassing in relation to Far-Target Location (FTL) systems include a Gyrocompass Modeling and Simulation System (GMSS). The GMSS is a modularized software system which has four major components: the 6DOF Motion Simulator, the IMU Sensor Simulator, the Gyrocompass System and Calibration Process Simulator, the Gyrocompass System Evaluation and Analysis Module. Each module has one or two graphic user interfaces (GUIs) as user interfaces for simulation components selection and parameter setting. The modular architecture of GMSS makes it very flexible for programming and testing. And, the component-based software development technology greatly eases system extension and maintenance. The simulators can be used as either an off-line tool or as a real-time simulation tool. The realization of the GMSS can be based on any computer platforms, for it is written in high level language and tools and is portable. The stochastic signal analysis and sensor testing and modeling tools comprise a suite of generic statistical analysis software, including Allan Variance and PSD analysis tools, which are available to every GMSS module and greatly enhanced the system functionality.

Abstract:
A method of converting a geospatial database into a compressive database for multiple dimensional data storage by constructing computer storage data language or format includes the steps of partitioning the geospatial database into a plurality of data segments; selecting a specific point position in each of the data segments as a reference point position (RPP), and then forming a set of reference point positions for the original geospatial database; providing a coordinate origin point for each of the data segments; converting the geodetic coordinates of the original geospatial database within each of the data segments into corresponding local coordinates, and converting the set of reference point positions and the local geodetic coordinates of each of the data segments into pixel coordinates in form of a pixel coordinate system to form a specific digital map database.
