Inventor: CRICHLOW HENRY B
IPC: E21B43/24
Filed: 2006-05-09
Abstract: Recovery of viscous hydrocarbon by hot fluid injection into subterranean formations is assisted by using a specially designed and under-reamed vertical wellbore with multiple injection perforations separated from the production perforations by a moveable packer. In this oil recovery method the operator drills a typical vertical well, in which a cavity is developed below the pay zone by under-reaming the vertical wellbore to form a collection cavity. This under-reaming can be made up to several feet in diameter using standard reaming technology and tools. Steam is injected into the upper perforations and is prevented from bypassing the cold formation by a vertical hydraulic seal developed in an annular communication zone. Hot oil is produced into the lower perforations and is collected in the reamed out production cavity. A producing mechanism including pumping equipment lifts the produced oil from the central cavity to the surface.

Title: Super-resolution image processing
Inventor: VOLOVELSKY KARNI
IPC: G06T5/50
Filed: 2005-02-01
Abstract: A method for iterative derivation of a master image from sampled images of non-identical, at least partially overlapping, regions of a scene. The method includes defining a transformation operator mapping positions within the master image to corresponding positions in the sampled image; a distortion operator simulating a modulation transfer function associated with an imaging sensor from which the sampled image was generated; and a sampling operator for reducing an image from the output resolution to the resolution of the sampled image. For each sampled image the transformation operator, distortion operator and sampling operator are applied to a current master image hypothesis to generate a predicted image A difference image is calculated which has pixel values corresponding to the difference in corresponding pixel values between the sampled image and the predicted image. A back-projection of each of the difference images is performed to generate a correction image for the current master image hypothesis. Finally, the correction images are employed to perform a correction to the current master image hypothesis to generate a new master image hypothesis. The correction to the current master image hypothesis includes combining the correction images by deriving a weighted average of values of corresponding pixels in the correction images. The weight of each pixel in each correction image is calculated as a function of a distance as measured in the sampled image between: a point in the sampled image to which the pixel in the correction image is mapped by the transformation operator;  and at least one pixel centroid proximal to that point.

Inventor: BRYMAN DOUGLAS
IPC: G01T1/164
Filed: 2005-03-18
Abstract: An improved gamma ray detector and method for discriminating between "true"  pairs of gamma rays produced by a single positron annihilation event and those randomly occurring "pairs" of gamma rays that may fall within the conventional acceptance criteria for "true" pairs. The gamma ray detector incorporates an additional array of "veto" detectors arranged adjacent or around a primary detector array. The array of "veto" detectors is configured to detect gamma rays that escape detection in the primary detector array. The detection data from both the primary detector array and the veto detector array are used as inputs into a discrimination circuit for "vetoing" those pairs of gamma rays detected by the primary detector array that are likely to be the result of two or more unrelated positron annihilation events. By increasing the proportion of "true" events used in image reconstruction, the apparatus and method may improve the quality of the resulting image, reduce the image processing time and/or reduce the need for subsequent data collection and/or manipulation.

Title: System for live audio presentations
Inventor: WEITZ JOHN C
IPC: H04R3/00
Filed: 2005-09-09
Abstract: In a live audio presentation system, a stage rack and a front of house rack are interconnected by a transmission medium that transmits digital audio data and control information between them. Packets of digital audio data and control information are sent at the audio sampling rate. The packets of data are encoded using an encoding technique that provides unique codes that may be detected, thus enabling clock recovery of a clock signal embedded in the data packets. Data packets may include data for error checking. A serial digital transmission medium may be used as the transmission medium. Such a transmission medium uses low voltage signals and supports high bit rates. The system is synchronized by the FOH rack which transmits data to the stage rack according to a local audio sample clock or an external audio sample clock to which it synchronizes. This clock is embedded in data packets sent to the stage rack. The stack rack recovers the audio sample clock from data received from the FOH rack and synchronizes its receive and transmit operations to this recovered clock. The FOH rack recovers the audio sample clock from data received from the stage rack and synchronizes its receive operations to this recovered clock. The FOH rack may include an embedded computer that processes the digital audio data, and may include DSP processing that handles so-called plug-in software. A digital audio workstation or sequencer also may be connected to the FOH rack to either record the live presentation or to inject edited, recorded audio into the live presentation.
