  • Patent number: 11972987
    Abstract: A machine learning model for each die for imputing process control parameters at the die. The model is based on wafer sort parametric measurements at multiple test sites across the entire wafer, as well as yield results for the wafer. This allows for a better analysis of outlier spatial patterns leading to improved yield results.

  • Publication number: 20240112333
    Abstract: In certain embodiments, a system, a computer-implemented method, and computer-readable medium are disclosed for enhanced ophthalmic visualization. A plurality of images corresponding to different portions of the electromagnetic spectrum are obtained and combined, such as by pixel-wise subtraction to obtain a combined image. The images may be weighted with weights selected to enhance visualization of features, such as layers of the retina or features corresponding to pathologies. The combined image may be processed, such as by a machine learning model, to extract features.

  • Patent number: 11941899
    Abstract: Apparatuses, systems, and techniques generate poses of an object based on image data of the object obtained from a first viewpoint of the object and a second viewpoint of the object. The poses can be evaluated to determine a portion of the image data usable by an estimator to generate a pose of the object.

  • Patent number: 11931909
    Abstract: Apparatuses, systems, and techniques generate poses of an object based on data of the object observed from a first viewpoint and a second viewpoint. The poses can be evaluated to determine a portion of the data usable by an estimator to generate a pose of the object.

  • Publication number: 20240076270
    Abstract: Synthetic ?v?6 integrin ligands of Formula I having serum stability and affinity for integrin ?v?6, which is a receptor expressed in a variety of cell types, are described. The described ligands are useful for delivering cargo molecules, such as RNAi agents or other oligonucleotide-based compounds, to cells that express integrin ?v?6, and thereby facilitating the uptake of the cargo molecules into these cells. Compositions that include ?v?6 integrin ligands and methods of use are also described.

  • Patent number: 9617487
    Abstract: A process for converting organic MSW into liquid fuels or chemical products in almost quantitative yield via catalytic one-pot hydrolytic depolymerization of organic MSW. The organic MSW comprises all organic materials that exists in municipal solid waste, such as paper and paperboard, food scraps, yard trimmings, rubber, leather, textiles, wood, plastics, etc. The process is the first one over the world for resourcing municipal solid waste.

  • Publication number: 20160083326
    Abstract: A process for converting lignocelluloses selectively into liquid fuels and fine chemicals uses one step of reaction and one step of isolation and separation. The process has the fewest steps of operation for converting biomass into products compared with all known biorefining processes.

  • Patent number: 9181166
    Abstract: Lignocelluloses are selectively hydrolyzed into only two kinds of products in an one-pot, quantitative reaction. Lignin is reduced into small molecular aromatics without using reductants. Simultaneously, cellulose and hemicellulose are oxidized into small organic acids without using oxidants. A catalytic method is invented for oxygen-transfer from lignin to cellulose or hemicellulose. There is neither gasification nor black tar formation observed during the hydrolytic depolymerization.

  • Publication number: 20070201989
    Abstract: A gear pump system comprises a gear pump having an inlet, an outlet, and at least one rotating gear for pumping fluid from the inlet to the outlet and producing an output flow characterized by pressure pulses arising from the geometry of the teeth of the gear; and at least one valve operative to vary the output flow in timed relation to the rotation of the gear for counteracting the pressure pulses, thereby to reduce the amplitude of the pressure pulses.

  • Publication number: 20070178003
    Abstract: A gear pump comprising a gear chamber having opposite side walls; a pair of gears disposed within the gear chamber with teeth thereof meshed with one another, the meshed teeth forming a trap region in which fluid becomes entrapped during rotation of the gears; inlet and outlet chambers on opposite sides of the meshed teeth of the gears and separated from one another by the meshed teeth of the gears; a ripple chamber; and a first passage connecting the ripple chamber to the trap region, whereby the trapped high pressure fluid will flow from the trap region to the ripple chamber to dampen the otherwise generated high pressure pulse.
