| 20120099395 | DETECTING STRUCTURAL CHANGES TO UNDERWATER STRUCTURES - A method and system that can be used for scanning underwater structures. The method and system allow a user to gain a better understanding of an underwater structure. For example, the method and system detect change(s) to an underwater structure. An acoustic sonar wave is directed toward an underwater structure, and a reflected acoustic sonar wave is received and processed to produce a three dimensional image. Data points of this three-dimensional image of the underwater structure are aligned to a pre-existing three dimensional model of the underwater structure. A change detection model is generated based on the aligned 3D images, and the change detection model is compared to the pre-existing three dimensional model of the underwater structure. Based on the comparison, occurrences of structural changes in the underwater structure are detected. | 04-26-2012 |
| 20120099400 | ESTIMATING POSITION AND ORIENTATION OF AN UNDERWATER VEHICLE RELATIVE TO UNDERWATER STRUCTURES - A method and system that can be used for scanning underwater structures. For example, the method and system estimate a position and orientation of an underwater vehicle relative to an underwater structure, such as by directing an acoustic sonar wave toward an underwater structure, and processing the acoustic sonar wave reflected by the underwater structure to produce a three dimensional image of the structure. The data points of this three dimensional image are compared to a pre-existing three dimensional model of the underwater structure. Based on the comparison, a position and orientation of an underwater vehicle relative to the underwater structure can be determined. | 04-26-2012 |
| 20120099402 | BUILDING A THREE-DIMENSIONAL MODEL OF AN UNDERWATER STRUCTURE - A method and system are described that can be used for scanning underwater structures. The method and system allow a user to gain a better understanding of an existing underwater structure. For example, the method and system allow for building a three dimensional model of an underwater structure. A sonar wave is directed toward an underwater structure, and a reflected sonar wave is received. Initial 3D data points are obtained from the reflected sonar wave, and are configured to provide a three-dimensional image of the underwater structure. A working alignment model of the underwater structure is generated by the initial data points. As new 3D sonar data is collected, the new 3D sonar data is aligned with and added to the alignment model. | 04-26-2012 |
| 20120101715 | ESTIMATING POSITION AND ORIENTATION OF AN UNDERWATER VEHICLE BASED ON CORRELATED SENSOR DATA - A method and system are described that can be used for combining two sources of position and orientation (pose) information where the information from one source is correlated with the information from the other and the sources produce information at differing rates. For example, the method and system allow for estimating position and orientation (pose) of an underwater vehicle relative to underwater structures by combining pose information computed from a 3D imaging sonar with pose information from a vehicle navigation system. To combine the information from the two sources, a determination is made as to whether to generate a forward prediction of the pose estimate of one of the sources relative to the other, and generating the forward prediction if needed. An updated pose of the underwater vehicle is determined based on the fused pose estimate, and which is used for vehicle guidance and control. | 04-26-2012 |

| 20090018779 | Flexible glucose analysis using varying time report deltas and configurable glucose target ranges - A diabetes data management system selects variable threshold parameters to that are utilized in a report. A first low threshold glucose reading and a first high threshold glucose reading for a before meal event timeframe are selected. A second low threshold glucose reading and a second high threshold glucose reading are selected for an after meal event timeframe. The threshold readings are stored in a database. The diabetes data management system analyzes glucose behavior around meal events. The system receives a plurality of glucose readings for a time period, receives a first time range as a pre-meal analysis period for the first meal event and receives a second time range as a post-meal analysis period for the first meal event. The system creates a graph which highlights the pre-meal analysis period, the post-meal analysis period, and displays the plurality of glucose readings for the time period. | 01-15-2009 |
