  • Publication number: 20250027176
    Abstract: An injection regulation and control device includes blast furnace tuyeres for introducing rich oxygen or pure oxygen to form tuyere raceways. Temperature-adjusting injection openings are evenly formed in the circumferential direction of a blast furnace and inject a hydrocarbon component-containing injection object to the blast furnace. The temperature-adjusting injection openings are located, in an axial direction, within a height range where a soft melting dripping zone is located and are not lower than the positions of the blast furnace tuyeres. The hydrocarbon component-containing injection objects are enabled to undergo a thermal cracking reaction by utilizing the temperature in the vicinity of the tuyere raceways to form a hydrocarbon thermal cracking heat absorption area. Gas products generated by the thermal cracking reaction of the hydrocarbon component-containing injection objects increase the blast furnace gas volume.

  • Patent number: 10775462
    Abstract: A system and method is provided that includes acquiring chemical exchange saturation transfer (CEST) data with the MRI system and generating an acquired Z-spectrum (Z) from the CEST data. The system and method also includes computing an estimated direct water saturation (Z?) based using at least one of relaxation measurements derived from the CEST data or imaging parameters used to acquire the CEST data with the MRI system, computing a direct saturation corrected Z-spectrum (?Z) using the acquired Z-spectrum (Z) and the estimated direct water saturation (Z?), and generating a CEST image of the subject using the direct saturation corrected Z-spectrum (?Z).

  • Patent number: 10726552
    Abstract: The present disclosure relates to systems and methods for determining quantitative chemical exchange or exchangeable proton information from a region-of-interest in a subject. The methods and systems use adaptive fitting to quantify magnetic resonance (MR) data, such as chemical exchange saturation transfer magnetic resonance imaging (CEST MRI) images, using initial values based on, for example, Lorentzian fitting. Images are iteratively less downsampled until quantitative maps of desired resolution are obtained. Such an approach allows for reliable fitting at a faster fitting speed, and is less susceptible to suboptimal signal to noise (SNR) than conventional methods.

  • Publication number: 20150169924
    Abstract: The present laser barcode scanner employs (i) a simplified scan mechanism made from a semi-flexible substrate that eliminates complicated optical assemblies, (ii) a layout with location features eliminating the need for special alignment, and (iii) a layout with all surface mounted devices on a single layer eliminating the need for extra soldering. Together these strategies, when used with a method of mitigating stray-light by separating light paths with a circuit board, combine to achieve a laser barcode scanner of unique simplicity and performance.
