  • Patent number: 12154358
    Abstract: The present system and method relate generally to the field of Robotic Process Automation, particularly to a form data extractor for document processing. The system and method relate to a form extractor for document processing using RPA workflows that can be easily configured for different document types. The form extractor includes a set of templates for identifying the document type (classification) and extracting data from the documents. The templates can be configured, i.e., by the user, by defining the fields to be extracted and the position of the field on the document. The form extractor is resilient to changes in the position of the template on a page, as well as to scan rotation, size, quality, skew angle variations and file formats, thus allowing RPA processes to extract data from documents that need ingestion, independent of how they are created.

  • Publication number: 20240363188
    Abstract: Memory cells may store multiple bits per cell. For example, three-level cell (TLC) memory stores three bits per cell using eight voltage levels. The number of memory cells at each voltage is approximately the total number of cells divided by the number of voltage levels. The number of memory cells above a certain read voltage is the CFByte value for the read voltage. Based on a difference between the CFByte value and a target CFByte value for the read voltage, an adjustment value is determined. Characteristics of an individual memory device may be determined by finding several CFByte values for a small range of read voltages. Using the gathered CFByte values, a DAC adjustment value is determined for the individual memory device.

  • Publication number: 20240249789
    Abstract: Aspects of the present disclosure configure a memory sub-system controller to adaptively allocate word lines (WLs). The controller accesses reliability data of a set of main WLs of a block of the set of memory components. The controller determines that one or more WLs of the set of main WLs of the block are associated with respective reliability data that transgress a threshold and, in response to determining that the one or more WLs are associated with the respective reliability data that transgress the threshold, replaces the one or more WLs of the set of main WLs of the block with one or more dummy WLs. The controller programs data into the block using the one or more dummy WLs instead of the one or more WLs of the set of main WLs of the block.

  • Publication number: 20070270598
    Abstract: The present invention relates to an improved process for one pot conversion of artemisinin into artelinic acid, which reduces the three step (three pot) conversion of artemisinin to artelinic acid in one step (one pot). The process of preparation of artelinic acid involves stirring of artemisinin with sodium borohydride, catalyst, polyhydroxy compound or chlorotrimethylsilane or amberlyst-15 resin and methyl p-(hydroxymethyl) benzoate, filtration of undissolved, unwanted reaction products and finally stirring of the filtrate with alcoholic or aqueous alkali hydroxide.
