| 20100090772 | OSCILLATOR WITH DELAY COMPENSATION - In the many microelectronics applications, delays present in circuitry can affect both the design and the function of the circuitry. One example of delays impacting the function of a circuit is a relaxation oscillator, where delays present in comparator circuits and latches can cause its frequency to vary beyond desired ranges. Here, a relaxation circuit with delay compensation is described. | 04-15-2010 |
| 20120013390 | DISPLAYPORT SWITCH - In versions 1.1a and 1.2 of the DISPLAYPORT™ standard, capacitors are used between a sourcing circuit and a switch for the auxiliary channel. As a result, these capacitors are generally uncharged when the switch activates the auxiliary channel, which can result in errors. Here, a switch is employed that uses precharge circuits to precharge these capacitors. Thus, errors due to charging of these capacitors can be reduced. | 01-19-2012 |

| 20110273959 | Data Acquisition and Prestack Migration Based on Seismic Visibility Analysis - Seismic visibility analysis of selected subsurface structures is employed to determine surface locations offering high visibility of target events. These locations can then be used as a basis for acquiring additional seismic survey data and/or selecting existing traces for re-migration with more sophisticated migration methods. With either usage, the newly migrated data is expected to offer enhanced images of the target event. In some embodiments, the visibility determination includes using a wave equation based propagator to find, for each of multiple simulated shots, a reflection wavefield from the target event in a seismic model; and to calculate, for each of multiple receiver positions, a contribution signal from each reflection wavefield. The visibility determination further includes converting each contribution signal into a source-receiver visibility value. Because data acquisition and/or re-migration is limited to the selected region, the imaging effort for the target event is significantly reduced. | 11-10-2011 |
| 20120020186 | Seismic Imaging Systems and Methods Employing a Fast Target-Oriented Illumination Calculation - In various disclosed seismic imaging systems and methods, a fast target-oriented illumination calculation technique is employed to obtain a data volume or “matrix” of approximate illumination values. These illumination values enable an image matrix of “true reflectivity” values to be found. The illumination values are derived from Green's functions which, rather than being calculated and re-calculated on a shot-by-shot basis, are calculated in multi-shot groups and combined with a rolling-sum to greatly reduce the computational overhead. As a consequence, the disclosed systems and methods can provide target region illuminations more quickly and/or with higher quality than those systems relying on conventional 3D wave-equation illumination. | 01-26-2012 |

| 20110075516 | Seismic Imaging Systems and Methods Employing Tomographic Migration-Velocity Analysis Using Common Angle Image Gathers - In at least some embodiments, the system obtains shot gathers for a survey region and migrates the shot gather data with an initial velocity model to obtain angle-domain common image gathers. The system processes the common image gathers to determine depth residuals and corresponding angle-dependent time deviations throughout a seismic survey region. The system solves a set of tomographic equations which employ ray theory to establish a relationship between a travel time deviation and the depth residual of a reflector in the depth-offset ray parameter (z,p) domain. The resulting updates are applied to the velocity model and can be used to re-migrate the shot gather data. The system generates a representation of the survey region that can be displayed to a user. | 03-31-2011 |
