摘要:
Systems and methods for reducing NOx emissions using a branched exhaust system with a first and second turbine including an emission-control device containing a zeolite, are described. In one example approach, a method comprises: during a first duration when exhaust temperature is below a first temperature threshold, directing exhaust gas through the second turbine and the emission-control device, and adjusting the second turbine to control intake boost; and during a second duration following the first, directing exhaust gas through the first turbine, and adjusting the first turbine to control intake boost. The emission-control device may be purged when exhaust temperature is above a second temperature threshold higher than the first temperature threshold, where during the second duration exhaust gas does not flow through the emission-control device.

A strainer is developed for mounting in a fluid system or a pipeline to filter the foreign objects remained in the fluid, thereby preventing malfunctioned operation, default and occlusion of the fluid machinery and the pipeline due to floating and drifting solids, and which includes an inlet and an outlet formed in a straight line and an omega-type screen joined to a cylindrical main body having a closed lower portion, thereby minimizing a transformation of a flow channel while maximally providing a screening face, and allowing a user to easily disassemble and clean the screen. The strainer can raise operational efficiencies of the fluid machine and the pipeline and remarkably reduce operational expenses by minimizing energy loss in the fluid, and reduce maintenance cost and ensure durability of the fluid machine and the pipeline by ensuring convenience in cleaning and maintaining the screen of the strainer.

摘要:
A fuel vapor management system for an automotive vehicle includes a vapor tower in fluid communication with a vapor purge outlet of a fuel pump. A fluid treatment section, such as a screen, is disposed between the fuel pump vapor purge outlet and the vapor tower. The fluid treatment section reduces the size and momentum of purged vapor bubbles such that the purged vapor bubbles in the vapor tower may rise in the vapor tower and separate from liquid fuel thereby, allowing liquid fuel to flow out of the vapor tower and allowing fuel vapor to escape from the vapor tower away from the inlet of the fuel pump inlet.

The present invention relates to an emission control system for reducing gases from the exhaust of a combustion engine. In at least one embodiment, the emission control system includes an exhaust passage for transporting the exhaust from the combustion engine, and a particulate filter and selective catalytic reduction (SCR/PF) unit disposed within the passage, with the unit having a plurality of spaced filter walls extending axially along the passage and selective catalytic reduction catalyst variably loaded on the unit to provide a more uniform pressure drop relative to a unit having uniformly loaded catalyst.

In the liquid crystal display panel of a horizontal electric field type, a gate pattern includes a gate electrode provided at a substrate, a gate line connected to the gate electrode and a lower gate pad electrode connected to the gate line. A data line is disposed to cross the gate line and the common line, having a gate insulating film therebetween to thereby define a pixel area. A thin film transistor is positioned at each intersection between the gate line and the data line. A transparent electrode pattern includes a pixel electrode electrically connected to the thin film transistor and disposed such that at least a portion thereof is parallel to the common electrode. An opaque conductive pattern is disposed to overlap with the transparent electrode pattern.

An audio/video connection apparatus for an audio/video system having a television receiver, an audio amplifier and a plurality of components. The audio/video connection apparatus includes at least one common video connection line for connecting a television receiver to a plurality of components so that video signals from the television receiver can be inputted to the plurality of components; and at least one common audio connection line for connecting an audio amplifier to the plurality of components so that audio signals from the audio amplifier can be inputted to the plurality of components, and so that video and audio signals can be inputted and outputted through the common lines to/from the components, thereby reducing the number of the output/input terminals and lines. The use of the common lines avoids increasing the number of input/output terminals and lines when the connected audio and video components are increased in number and permits, for example, recording from a first VCR to a second VCR while watching the program of the first VCR on a display unit.

A point-type radio controller using infrared rays facilitates an installation of a receiving sensor by arranging an infrared transmitter and an infrared receiver at right angle to each other, and accurately computes a coordinates-position of a designated point through double calculating coordinates value of a point in a constant time. The point-type radio controller using infrared rays includes a transmitting means for transmitting an infrared signal having a constant period, and having infrared diodes as a plurality of signal generators in the direction of Y-axis in order to achieve a constant angle; a receiving means for receiving the infrared signal by mounting infrared receiving sensors on a display device at a right angle to the infrared diodes in the direction of X-axis; and a controlling means for calculating coordinates-position of an indicated point by using an intensity difference between the infrared signals received by the receiving means, and displaying a calculated point on a display screen.

Functional and temporal aggressor classification methods that provide increased efficiency and accuracy for classifying aggressor signal lines of an integrated circuit for purposes of analyzing crosstalk of the circuit. In one aspect, an aggressor classification method for analyzing crosstalk of a circuit comprises (a) obtaining CNF (conjunction normal form) clauses of signal lines from a victim to a predetermined signal line and from an aggressor to a predetermined signal line for circuit analysis using a backward search, and obtaining CNF clauses of the victim and the aggressor, and summing up the CNF clauses of the victim and the aggressor to obtain a final CNF clause, (b) obtaining CNF clauses with respect to various cases in which logic values of the victims and aggressors are varied in the final CNF clause, and (c) analyzing the CNF clauses obtained in step (b) to classify aggressors as true or false aggressors, wherein an aggressor is classified as a true aggressor if a result of a given CNF clause has a vector, and classifying an aggressor as a false aggressor if a result of a given CNF clause has no vector.
