20090291292 | OPTICALLY ACTIVE ELEMENTS INCLUDING MULTIPLE BEAD LAYERS - The present application relates to optically active elements and the methods of making these elements. The optically active elements include multiple layers of optically active beads positioned adjacent to a core particle. The methods of making these optically active elements involve applying multiple layers of optically active beads around a core particle. At least some of the optically active elements exhibit increased durability and/or performance due to the inclusion of multiple layers of optically active beads. | 11-26-2009 |

20120130569 | SYSTEMS AND METHODS FOR SEA STATE PREDICTION AND AUTOMATED VESSEL NAVIGATION - Systems and methods for sea state prediction and autonomous navigation in accordance with embodiments of the invention are disclosed. One embodiment of the invention includes a method of predicting a future sea state including generating a sequence of at least two 3D images of a sea surface using at least two image sensors, detecting peaks and troughs in the 3D images using a processor, identifying at least one wavefront in each 3D image based upon the detected peaks and troughs using the processor, characterizing at least one propagating wave based upon the propagation of wavefronts detected in the sequence of 3D images using the processor, and predicting a future sea state using at least one propagating wave characterizing the propagation of wavefronts in the sequence of 3D images using the processor. Another embodiment includes a method of autonomous vessel navigation based upon a predicted sea state and target location. | 05-24-2012 |
20120265380 | Target Trailing with Safe Navigation with colregs for Maritime Autonomous Surface Vehicles - Systems and methods for operating autonomous waterborne vessels in a safe manner. The systems include hardware for identifying the locations and motions of other vessels, as well as the locations of stationary objects that represent navigation hazards. By applying a computational method that uses a maritime navigation algorithm for avoiding hazards and obeying COLREGS using Velocity Obstacles to the data obtained, the autonomous vessel computes a safe and effective path to be followed in order to accomplish a desired navigational end result, while operating in a manner so as to avoid hazards and to maintain compliance with standard navigational procedures defined by international agreement. The systems and methods have been successfully demonstrated on water with radar and stereo cameras as the perception sensors, and integrated with a higher level planner for trailing a maneuvering target. | 10-18-2012 |
