| 20110204892 | SPIN ECHO SPI METHODS FOR QUANTITATIVE ANALYSIS OF FLUIDS IN POROUS MEDIA - A method of measuring a parameter in a sample by imaging at least a portion of the sample using a spin-echo single-point imaging (SE-SPI) pulse sequence. This method involves applying a pure phase encoding to the SE-SPI pulse sequence, acquiring a multiplicity of echoes, and determining the spatially resolved T2 distribution. In another embodiment, individual echoes are separately phase encoded in a multi-echo acquisition and the SE-SPI pulse sequence is a hybrid SE-SPI sequence. In another embodiment, an external force can be used to build up a distribution of saturations in the sample, and a T2 distribution can be measured for the sample, which is then used to determine a parameter of the sample. A spatially resolved T2 distribution can also be measured and a resulting spatially resolved T2 distribution used to determine the T2 distribution as a function of capillary pressure. | 08-25-2011 |

| 20110049016 | BITUMEN UPGRADING USING SUPERCRITICAL FLUIDS - The invention provides systems and methods for extracting and upgrading heavy hydrocarbons from substrates such as oil sands, oil shales, and tar sands in a unitary operation. The substrate bearing the hydrocarbon is brought into contact with a supercritical or near-supercritical fluid, a source of hydrogen such as hydrogen gas, and a catalyst. The materials are mixed and heated under elevated pressure. As a consequence of the elevated temperature and pressure, upgraded hydrocarbon-containing material is provided in a single or unitary operation. In some embodiments, sonication can be used to improve the upgrading process. Fluids suitable for use in the process include carbon dioxide, hexane, and water. It has been observed that upgrading can occur within periods of time of a few hours. | 03-03-2011 |

| 20090265021 | METHOD OF MULTI-DIMENSIONAL NONLINEAR CONTROL - A computer implemented method of conducting closed-loop control of a physical system comprising the steps of carrying out an initialization of the physical system to commencing closed-loop control, evaluating the optimal constrained control move using the system error and the initial normalized matrix using a control move solver; calculating a first control action by the sum of delta u(0) and the initial control action; and implementing the result to the physical system by converting the control action to an output control signal to effect a change in at least one operating variable. | 10-22-2009 |
| 20090186658 | JOINT COMMUNICATION AND ELECTROMAGNETIC OPTIMIZATION OF A MULTIPLE-INPUT MULTIPLE-OUTPUT ULTRA WIDEBAND BASE STATION ANTENNA - Recent work has shown that in nearly line-of-sight (LOS) Multiple-Input Multi-Output (MIMO) wireless communication systems, spacing antennas according to the symbol wavelength rather than the carrier wavelength improves multiuser performance. MIMO systems have a heavy reliance on a multipath rich environment, which may not always be present in close range ultra wideband conditions. By adding reflector elements to the antenna structure, this multipath rich environment can be induced. The performance of the users with respect to the arrangement of antennas and reflector elements is a non-linear function that a genetic algorithm (GA) seems applicable for exploiting both symbol-wavelength spacing and multipath inducing reflector elements. A GA optimization is used to determine the optimum characteristics for antennas and reflector elements. MIMO system models with four users, and three, four, and five antennas are considered using a two-dimensional LOS channel with additive white noise. Subsequently, a GA optimization design and approach for solving this problem in three-dimensional space is presented. The addition of reflector elements to purposely increase multipath requires additional design considerations incorporating distributed processing, ray-tracing, and the determination of the channel impulse response. | 07-23-2009 |
