  • Fingerprint classification system and method using regular expression machines
    Patent number: 9971929
    Abstract: A fingerprint classification system and method for extracting the dominant singularity from a fingerprint image are described. The fingerprint classification system and method receive as an input a digital fingerprint image and the image is preprocessed to generate an enhanced and more accurate image. Feature pattern calculations are performed on the updated image to generate an Orientation Feature Vector. The Orientation Feature Vector is processed using a Regular Expression Machine classifier prediction model to generate a class label for the digital fingerprint image that was input.
    Type: Grant

  • Removable pressure-sensitive adhesive compositions comprising acrylic based emulsion polymers
    Patent number: 5240989
    Abstract: A removable pressure sensitive adhesive composition comprises an acrylic-based emulsion polymer having a gel content of from about 70 to about 90%. The polymer comprises about 90 to 99.5 parts alkyl acrylate monomers, up to about 2 parts polar monomers and up to about one part of a multifunctional acrylate monomer. The polymer is sythesized in the presence of a combination of anionic and non-ionic emulsifiers wherein the amount of anionic emulsifer exceeds the amount of non-ionic emulsifier. The composition preferably comprises one or more adhesion stabilizers, preferably a plasticiser in an amount of up to about 3% by weight and a protective colloid in an amount of up to about 1% by weight.
