  • Patent number: 11897803
    Abstract: This Invention Patent application provides a comprehensive program for control of organic and inorganic contaminants from paper production processes and other potentially pollutant industries through the integrated action of three continuous treatment systems, referenced herein as “3WAY”, with a first system aimed at the treatment of process waters for reuse, more specifically “white or clarified water” present in the “wet end” of paper and cellulose machines, allied to a second system based on the use of an adsorbent clay mix equipment that enables treatment of the cellulose pulp in previous phases of the process up to the machine circuit, in addition to a third system that carries out the cleaning of contaminant deposits present in clothing (felts and wires) or other machine parts through application of a heated and pressurized cleaning solution with a high detergency power.

  • Publication number: 20220067307
    Abstract: A system for training multilingual machine translation evaluation models and methods for making and using the same. The system can utilize a multilingual embedding space to leverage information from system inputs, including original source language, at least one machine translation of the original source language and at least one reference translation. The system can improve the accuracy of translation quality predictions by assigning a translation quality score based on the system inputs to be assigned to the machine translation. The translation quality score advantageously can demonstrate value added by using the original source language as an input to machine translation evaluation models.

  • Publication number: 20210148051
    Abstract: This system is intended for paper and cellulose manufacturing process, in order to enable partial or full talc replacement in controlling pitch and stickies, in addition to helping in retention and drainage in paper and cellulose manufacturing processes. The chemical methodology and processes employed herein primarily involve the mix of adsorbent clays such as bentonite and hydrotalcite in the form of a slurry mix, obtained through a thermodynamic equipment called continuous flow shearing chamber (502), which provides delamination in pressure and temperature conditions, able to enhance the exposure of adsorption sites.

  • Patent number: 9665680
    Abstract: A circuit design system includes a simulator that determines an average charging current provided by each current insertion point in a cell and an average charging current along a path in the cell between a reference pin position and a candidate pin position. A candidate pin placement tester updates the average charging current along the path by adding the average charging current of each insertion point to the average charging current along the path to produce an updated average charging current along the path and uses the updated average charging current along the path to determine a time to failure for the cell.

  • Patent number: 8731505
    Abstract: A tuner system for receiving a plurality of frequency bands includes a low noise amplifier coupled with a band selection filter to select a desired band. The tuner system further includes a complex RF filter to produce a complex RF signal from the selected band. The tuner system includes two double-quadrature converters, the first double-quadrature converter frequency down-converts the complex RF signal to a complex baseband signal. The complex baseband signal passes through a baseband filter that contains two identical lowpass filters for obtaining a baseband in-phase (I) signal and a quadrature (Q) signal. The second double-quadrature converter up-converts the baseband I and Q signals to respective IF I and Q signals that are significantly free of the positive third IF harmonic. The third IF-harmonic free I and Q signals are further processed by a complex bandpass filter. The bandpass filter has a programmable frequency center and a programmable bandwidth.

  • Publication number: 20070159984
    Abstract: A method of producing a flexible timing-driven routing tree is provided. Two or more target nodes are sorted in accordance with data criticality. A source-sink grid is built from one or more source nodes and the two or more target nodes. An initial routing tree is built comprising the one or more source nodes. A routing tree generation algorithm is executed on the initial routing tree, utilizing the sorted two or more target nodes and the source-sink grid in accordance with a user-defined timing factor to construct a flexible timing-driven routing tree. The user-defined timing factor specifies an extent of isolation for a routing path from a given one of the one or more source nodes to a given one of the two or more target nodes.
