  • Patent number: 12123387
    Abstract: A cover apparatus for directing a water current to rotate a waterwheel includes a shield comprising a first side panel, a second side panel, and a perimeter panel which define a cavity to receive the waterwheel. The cover apparatus is rotatably mountable to a shaft so that the cover apparatus rotates freely around the shaft to cover selected portions of the waterwheel. Typically, the shield covers one half of the waterwheel so that the water current only flows passed an uncovered half of the waterwheel to rotate the waterwheel. Fins are mounted to the perimeter panel to facilitate rotation of the shield around the waterwheel by the water current. An electricity generation system is described and claimed which uses the waterwheel and the cover apparatus.

  • Patent number: 11221194
    Abstract: An integrated architecture and its associated sensors and processing software subsystems are defined and developed allowing a conventional unguided bullet to be transformed into a guided bullet without the use of an on-board inertial measurement unit (IMU). Some important SW components of the present disclosure include a target state estimator (TSE); a bullet state estimator (BSE); Multi-Object Tracking and Data Association; NTS GL; and a Data Link. Pre-conversion of two angles and range information of an OI sensor from spherical coordinates into Cartesian coordinates eliminates the Jacobian dependency in the H matrix for the BSE, thus increasing the miss distance performance accuracy of the bullet target engagement system.

  • Patent number: 11199379
    Abstract: The system and method for EO/IR and RF sensor fusion and tracking using a dual extended Kalman filter (EKF) system provides a dynamic mixing scheme leveraging the strength of each individual sensor to adaptively combine both sensors' measurements and dynamically mix them based on the actual relative geometries between the sensors and objects of interest. In some cases the objects are adversarial targets and other times they are assets.

  • Patent number: 11009316
    Abstract: A method and system for nonlinear trajectory shaping guidance law capable of providing a robust guidance solution suitable for multi-mission, multi-mode operations. The nonlinear trajectory shaping guidance law offers (1) a dual layered GL gains calculation: (i) NTS time varying adjustment accounting for engine on/off and L/D variation and (ii) general explicit guidance algorithm based sub-optimal fixed-gain selection while still maintaining its trajectory shaping capability for short range to go missions; (2) flight path angle (FPA) command tracking and following to ensure a high probability of target destruction while minimizing collateral damages; (3) high precision impact point calculation factoring in target location errors or motion and maneuvering uncertainties; and (4) heading error angle minimization.

  • Patent number: 9418430
    Abstract: A scene correlation-based target system and related methods are provided. A reference image depicts a remotely-positioned object having identifiable characteristics, wherein a reference directional vector is established relative to the reference image. A target image of a general vicinity of the remotely-positioned object has an unknown directional vector, the target image having at least a portion of the identifiable characteristics. An inertial measuring unit has a scene correlation system, wherein the scene correlation system matches the portion of the identifiable characteristics of the target image with the identifiable characteristics of the reference image, wherein a slew angle between the reference image and the target image is calculated. A target image directional vector is derived from the calculated slew angle and the reference directional vector.
