Abstract: Systems and methods for cognitive information mining are provided. A cognitive information extraction system provides intelligent information extraction from documents in different formats, types and forms. Since a huge portion of the data and information is still stored in unstructured documents in physical format, the system provides for a framework to extract information from such documents. Further, even in the digital form, the documents are available in multiple different formats, which can act as a great hindrance to useful extract information. The invention focuses upon mitigating this scenario by combining multiple AI models and modules to create a framework for document processing and human-machine interaction for training and QC verification, wherein the framework provides user the flexibility to work upon multiple types of documents, and also ensures that accuracy is maintained while the information is being extracted.

Abstract: A device for facilitating positioning of a needle during a medical procedure may include a needle receiver configured for removable/reversible attachment of a proximal end of a needle; a stop set back from a distal end of the needle receiver and against which a needle received by the needle receiver abuts; and a trigger configured to move the needle receiver relative to the stop when activated by a user such that the stop forces detachment between the needle receiver and the needle. The device may monitor the pressure at the distal end of the needle as the needle is advanced and provide indication to a user when a predetermined pressure or pressure differential is reached.
