  • Patent number: 8682416
    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.

  • Patent number: 8509965
    Abstract: Collision with ground/water/terrain and midair obstacles is one of the common causes of severe aircraft accidents. The various data from the coremicro AHRS/INS/GPS Integration Unit, terrain data base, and object detection sensors are processed to produce collision warning audio/visual messages and collision detection and avoidance of terrain and obstacles through generation of guidance commands in a closed-loop system. The vision sensors provide more information for the Integrated System, such as, terrain recognition and ranging of terrain and obstacles, which plays an important role to the improvement of the Integrated Collision Avoidance System.

  • Patent number: 8510234
    Abstract: A real time kernel for deploying health monitoring functions in Condition Base Maintenance (CBM) and Real Time Monitoring (RTM) systems is disclosed in this invention. The Optimized Neuro Genetic Fast Estimator (ONGFE) allows embedding failure detection, identification, and prognostics (FDI&P) capability by using Intelligent Software Element (ISE) based upon Artificial Neural Network (ANN). ONGFE enables embedded fast and on-line training for designing ANNs, which perform very high performance FDI&P functions. An advantage is the optimization block based on pseudogenetic algorithms, which compensate for effects due to initial weight values and local minimums without the computational burden of genetic algorithms. It provides a synchronization block for communication with secondary diagnostic modules. Also a scheme for conducting sensor data validation is embedded in Smart Sensors (SS). The algorithms are designed for a distributed, scalar, and modular deployment.

  • Patent number: 8229163
    Abstract: The technology of the 4D-GIS system deploys a GIS-based algorithm used to determine the location of a moving target through registering the terrain image obtained from a Moving Target Indication (MTI) sensor or small Unmanned Aerial Vehicle (UAV) camera with the digital map from GIS. For motion prediction the target state is estimated using an Extended Kalman Filter (EKF). In order to enhance the prediction of the moving target's trajectory a fuzzy logic reasoning algorithm is used to estimate the destination of a moving target through synthesizing data from GIS, target statistics, tactics and other past experience derived information, such as, likely moving direction of targets in correlation with the nature of the terrain and surmised mission.

  • Patent number: 7239976
    Abstract: A platform residing viewing sensor and a pointing system/weapon. An operator system is remotely monitoring the scene on a display as viewed by the viewing sensor such that an operator system can gaze, acquire and track targets by scanning the scene with eyes and locking the eyesight onto a selected target and track the target with the eyes. The system further includes a dual camera sensor that follows and monitors the operator system's eyes motion so that the operator system can simultaneously monitor the external viewing sensor's scene, locking and tracking some selected target. The display coordinates of the selected target are utilized to point the pointing system/weapon on the external platform so that the operator system can fire at the target as desired. The problem is thus summarized as one of controlling the weapon pointing, movement and firing on a target that has been selected and is tracked by the eyes of an operator system viewing a display.

  • Patent number: 6757569
    Abstract: A filtering process is adapted for eliminating the need of prediscretizing a continuous-time differential model into a discrete-time difference model. It provides a universal robust solution to the most general formulation, in the sense that the system dynamics are described by nonlinear continuous-time differential equations, and the nonlinear measurements are taken at intermittent discrete times randomly spaced. The filtering process includes the procedures of validating the measurement using fuzzy logic, and incorporating factorized forward filtering and backward smoothing to guarantee numerical stability. It provides users a reliable and convenient solution to extracting internal dynamic system state estimates from noisy measurements, with wider applications, better accuracy, better stability, easier design, and easier implementation.
