IPC: E21B43/30
Filed: 2007-10-10
Abstract: A method for enhanced production of hydrocarbon fluids from an organic-rich rock formation such as an oil shale formation is provided. The method generally includes completing at least one heater well in the organic-rich rock formation, and also completing a production well in the organic-rich rock formation. The method also includes the steps of hydraulically fracturing the organic-rich rock formation from the production well such that one or more artificial fractures are formed, and heating the organic-rich rock formation from the at least one heater well, thereby pyrolyzing at least a portion of the organic-rich rock into hydrocarbon fluids. Pyrolyzing the organic-rich rock formation creates thermal fractures in the formation due to thermal stresses created by heating. The thermal fractures intersect the artificial fractures. As an additional step, hydrocarbon fluids may be produced from the production well. Preferably, the organic-rich rock formation is an oil shale formation.

Inventor: LEONG CHIOK KENG
IPC: H04B7/08
Filed: 2008-05-06
Abstract: The invention relates to the implementation of a digital signal processor that is required to process a large number of narrowband analogue input or output signals. Analogue processing is performed to combine multiple analogue signals together (with non-overlapping frequency bands) into a composite signal which is fed to a single analogue to digital converter. These signals come from different sources and would in a conventional implementation use individual converters. Analogue signal processing is used outside of the digital signal processor and digital processing is used inside to enable the original analogue signals to be reconstructed in the digital domain in the same format as if individual converters have been used. A similar technique can be applied to digital to analogue conversion interfaceswhere a digital combining operation is performed to combine digital sub-band signals into a single composite signal, prior to input to a single digital-to-analogue(DAC) converter for conversion to the analogue domain and subsequently to an analogue splitter device for separation into a plurality of analogue signals.Hence, the technique can be implemented in both transmitter and receiver systems.

Inventor: KITAZOE MASATO
IPC: H04W36/30
Filed: 2008-06-19
Abstract: A framework for the cell reselection and associated measurement behavior is proposed based on a state in which a UE is camped on the cell. If the UE is 'camped in any cell state', inter-frequency and/or inter-RAT measurements are prioritized over intra-frequency measurements. The proposed scheme helps the UE to find a suitable cell while in the camped on any cell state. If the UE subscribes to specific frequencies, separate measurement rules are implemented to aid the UE to find and camp on the preferred frequencies. The proposed scheme also considers access related information in addition to radio quality to help the UE in making cell selections thereby mitigating the UE from camping on restricted cells. Such aspects minimize situations wherein users are limited due to the service provided by an operator.

Abstract: Systems and methods for determining melting temperatures, Tm, for DNA from melt curve data. The systems and methods also allow for quantitative determination of gene amount based on peak height. A PCR analogy is used to perform quantization of an acquired melting curve dataset. The melting curve is transformed using a horizontal flip and a horizontal translation, and a double sigmoid equation is then fit to the data. Inverse translation and inverse horizontal flip transforms are applied to the equation to produce an equation based solution of the melt curve dataset. The equation based solution of the melt curve is then used to determine the first derivative (e.g., Tm value) and peak height.
