20110136700 | Method and System for Preventing Clathrate Hydrate Blockage Formation in Flow Lines by Enhancing Water Cut - The present invention includes a method for inhibiting hydrate formation blockage in a flow line used to transport hydrocarbon containing fluids. Water is added to a hydrocarbon containing fluid to produce a water cut enhanced hydrocarbon containing fluid. Salt may be added to the hydrocarbon containing fluids as well. Hydrate formation blockage is inhibited from forming within the flow line by the addition of the water and/or the salt. Sufficient water may be added such that the hydrocarbon containing fluid is converted from a water in oil emulsion to a water continuous emulsion. A system for preventing the formation of hydrate blockage in conduits is also provided. The system includes a flow line for transporting a hydrocarbon containing fluid and a water injection conduit fluidly connected to the flow line to add water to the flow line to increase the water cut of a hydrocarbon containing fluid flowing through the flow line. A salt dispenser may also be included which is used to increase the salinity of the hydrocarbon containing fluid. The system may further include a water separator to separate hydrocarbons from water which receives fluids from the flow line. The flow line, water separator and water injection conduit may cooperate to form a loop wherein water from the flow line may be separated by the water separator and a portion of the separated water is delivered back to the water injection conduit to be reinjected into the flow line. | 06-09-2011 |

20110063146 | MULTISTAGE CHOPPER STABILIZED DELTA-SIGMA ADC WITH REDUCED OFFSET - A relatively low frequency chopping operation is applied to a delta-sigma ADC to reduce DC offsets resulting from non-ideal component operation. Sequential chopping takes place outside a closed loop and may include an inverted polarity feedback for a part of the chopping period. Nested chopping involves chopping within the closed loop, and may include an inverted polarity feedback and a time shift. The feedback compensation for sequential and nested chopping permits the correct polarity feedback to be provided at the desired time in conjunction with sampling and quantization events. Integrating capacitor(s) may be swapped in relative polarity during nested chopping to preserve residual conversion information for the desired polarity. The ADC operation is non-temperature dependent and avoids modification to the useful signal, resulting in higher accuracy. | 03-17-2011 |
20110089977 | Systems and Methods of Low Offset Switched Capacitor Comparators - The disclosed systems and methods of low offset switched capacitor comparator reduce settling errors. The system operates in two major phases. During a first phase, the input voltage is sampled on the input capacitors and a differential amplifier is configured in a unity gain configuration to sample the amplifier offset. During the second phase, the input voltage difference is amplified at the output of the comparator. The amplifier transient sampling error is reduced by shorting the outputs of the differential amplifier for a shorting period at the start of the second phase. A clocked comparator at the output of the differential amplifier provides a fast comparison using internal positive feedback. The differential amplifier should have developed sufficient differential output voltage to overcome the offset of the clocked comparator. | 04-21-2011 |
20110089992 | Systems for Accurate Multiplexing - The disclosure presented herein provides example embodiments of systems for accurate multiplexing. The systems and methods presented may be suitable for non-limiting examples of analog to digital conversion with a switched input voltage (for a switched capacitor application) or any circuit with high voltage/high accuracy voltage multiplexing. In an example embodiment, pulsed current sources may be implemented to rapidly turn on and turn off the selected and unselected multiplexer ports while maintaining relatively low power consumption. A Kelvin input port may allow a high voltage input to be accurately sensed by avoiding a voltage drop associated with a selected pass gate p-channel FET channel resistance and parasitic wire resistance. The Kelvin input port biases the gate of a pass FET structure whose body terminals are allowed to remain floating. | 04-21-2011 |
