  • Patent number: 11915524
    Abstract: This disclosure relates generally to a method and system for online handwritten signature verification providing a simpler low cost system. The method comprises extracting signature data for the subject from a sensor array for the predefined time window at regular predefined time instants. Further, differentiating the matrix row wise and column wise to generate a row difference matrix and a column difference matrix. Further, determining an idle signature time fraction for the extracted signature data of the subject being monitored from the column difference matrix. Further, determining a plurality of signature parameters based on the row difference matrix and the column difference matrix.

  • Publication number: 20220024988
    Abstract: Embodiments include therapeutic peptides for preventing or reducing the transmission of a coronavirus such as SARS-CoV2. Also included are methods of using therapeutic peptides for reducing or preventing transmission of a coronavirus such as SARS-CoV2. The therapeutic peptides can prevent a region of the surface glycoprotein “spike” on SARS-CoV2 from interacting with angiotensin converting enzyme-2 (ACE-2) of host cells.
