20100004891 | METHOD OF ANALYSIS OF EFFECTS OF CARGO FIRE ON PRIMARY AIRCRAFT STRUCTURE TEMPERATURES - Embodiments provide systems and methods for analyzing effects of cargo fire on primary aircraft structure. A thermal profile of a suppressed fire in a cargo compartment of an aircraft is developed. The thermal profile is applied to a heat transfer model of structure of an aircraft, and structural integrity of the modeled structure is analyzed. The thermal profile may be developed by introducing a fire in a physical model of a cargo compartment instrumented with temperature sensors and determining profiles of temperature versus time. A heat transfer model of aircraft structure is built, boundary conditions are input into the heat transfer model, and the model is run. When analysis of the modeled structure determined structural integrity to be insufficient to satisfy flight certification requirements, structural parameters are modified, the thermal profile is applied to a heat transfer model of the modified structure, and the analysis is repeated. | 01-07-2010 |
20100098131 | ANALYSIS OF EFFECTS OF CARGO FIRE ON PRIMARY AIRCRAFT STRUCTURE TEMPERATURES - Systems for analyzing effects of cargo fire on primary aircraft structure are provided.

20110173430 | IT Automation Appliance Imaging System and Method - A system, method, and computer program product for harvesting an image from a local disk of a managed endpoint to an image library is provided. In an embodiment of the method for harvesting an image, a managed endpoint is provided with a boot image that causes the endpoint to instantiate a RAM disk and execute the boot image from the RAM disk. The boot image is used to harvest an image by determining data on a local disk of the managed endpoint to be included in the image that are not already stored in the image library. In one embodiment, this is done by comparing hashes calculated on the data on the local disk to hashes of data in the image library. The data not already stored in the image library are then copied to the image library. | 07-14-2011 |

20130071815 | Architecture for Full Motion Diagnostic Training with Trigger-Based Devices - Apparatus and associated methods relate to a training system adapted to display to a user three dimensional motion trajectory data of a trigger-based device temporally proximate to a trigger action. In an illustrative example, the training system may provide a near real-time graphical display and/or post-firing analysis with graphical display indications of firearm orientation in three axes before, during, or after a trigger action. Some embodiments may output post-firing analysis of the orientation or trajectory to a user of the firearm. The stored graphical display indications may be stored or displayed in substantially real time to a user or observer, who may provide corrective feedback to the user. The three axes of motion may be mutually orthogonal to define three dimensional space. Various embodiments may provide time-shifting of the graphical display indications, for example, to facilitate analysis of the three axis motion relative in time to trigger actions. | 03-21-2013 |
