20090212097 | Nested Storage Box And Retrofit For Hanging File Folders - A storage box for hanging file folders, which has an outer carton and an inner carton. The inner carton has a pair of removable reinforcing strips, which attach to opposing upper edges of the inner carton. Each hanging file folder is suspended by a pair of hangers that engage the reinforcing strips. The outer carton extends above the level of the file folders and their hangers, in order to engage a removable lid without interference from the hangers, the hanging file folders, or any index tabs that may be attached to the file holders. Optionally, the outer carton may have one or more handles. | 08-27-2009 |

20110089864 | Method and Apparatus for Controlling Power in a LED Lighting System - The LED light fixture includes white LEDs having multiple, different color temperatures. Preferably, white LEDs having color temperatures of about 3500 and about 5000 degrees Kelvin (K) are selected. The intensity of each LED may be varied and the light radiated from the LEDs is mixed together. The resulting light emitted from the housing is a white light having a variable color temperature ranging from about 3500 to about 5000 K. The housing is preferably extruded aluminum. A portion of the housing is configured to mix the light together and to focus the light such that the output light is about thirty degrees off center. Electrical loading is off set to minimize load on power supplies. | 04-21-2011 |

20140270393 | SYSTEMS AND METHODS FOR IMPROVING DIRECT NUMERICAL SIMULATION OF MATERIAL PROPERTIES FROM ROCK SAMPLES AND DETERMINING UNCERTAINTY IN THE MATERIAL PROPERTIES - A testing system can analyze a 3D digital volume of a material sample. The testing system can define several test volumes with each test volume including a different numbers of voxels. The test volumes can define the size of portions of the 3D digital volume to analyze. For each test volume, the testing system can acquire two adjacent portions of 3D digital volume that are the size of the test volume currently being analyzed. The testing system can calculate a petrophysical property value for the two adjacent portions of the 3D digital volume and can calculate the difference value between the two adjacent portions of the 3D digital volume. The testing system can repeat the process for the different test volumes. The testing system can plot the mean difference values for the different test volumes. The testing system can analyze the plot to determine a representative elementary volume that meets a predefined difference value. | 09-18-2014 |
20140270394 | Systems and Methods for Improving Direct Numerical Simulation of Material Properties from Rock Samples and Determining Uncertainty in the Material Properties - A testing system for analyzing a 3D digital volume of a material sample. The testing system defines several test volume sizes with each test volume size including a different numbers of voxels, defining the size of portions of the 3D digital volume to analyze. For each test volume size, the testing system acquires two adjacent portions of 3D digital volume at the test volume size currently being analyzed. The testing system calculates a material property value for the two adjacent portions of the 3D digital volume, and a difference value between the two adjacent portions of the 3D digital volume. The process is repeated over the different test volume sizes. The testing system calculates mean difference values for the different test volume sizes, from which it determines a representative elementary volume. | 09-18-2014 |
20150043787 | Image-Based Direct Numerical Simulation of Petrophysical Properties Under Simulated Stress and Strain Conditions - A testing system for performing image based direct numerical simulation to characterize petrophysical properties of a rock sample under the simulated deformation condition, for example as representative of subsurface conditions. A digital image volume corresponding to x-ray tomographic images of a rock sample is segmented into its significant elastic phases, such as pore space, clay fraction, grain contacts and mineral type, and overlaid with an unstructured finite element mesh. A simulated deformation is applied to the segmented image volume, and the resulting deformed unstructured mesh is numerically analyzed, for example by way of direct numerical simulation, to determine the desired petrophysical properties. | 02-12-2015 |
