    Abstract: Techniques for creating and manipulating software notes representative of physical notes are described. A note management system comprises a note recognition module configured to receive image data capturing a note having a plurality of color segments, wherein the note recognition module is further configured to generate a plurality of indicators, each indicator indicative of a color class of a pixel or group of pixels within the image data and based on color values of the pixel or group of pixels; and a note extraction module configured to determine general boundaries of the color segments of the note based on the plurality of indicators and extract content using the general boundaries, the content comprising a plurality of content pieces, each of the content pieces corresponding to one of the color segments of the note.

    Abstract: Aspects of the present disclosure relate to a method of making an abrasive article. The method can include providing a combination of a mesh backing and a fastener. The mesh backing has a first side and a second side and the mesh backing has a fastener disposed on the second side and intertwined through the mesh backing therein. The combination comprises a raised portion on the first side having a first dimension. The method can include calendering the first side of the mesh backing to form a calendered mesh backing such that the raised portion results in a second dimension. The second dimension is less than the first dimension. The method can include depositing a curable make layer precursor on a major surface of the calendered mesh backing, deposing a plurality of abrasive particles onto the curable make layer precursor, and at least partially curing the curable make layer precursor.

    Abstract: A porous coated abrasive article comprises a porous backing having opposed first and second major surfaces, and a porous abrasive layer disposed on the first major surface. The porous backing comprises a porous oriented thermoplastic film. The porous backing has a land portion and openings extending between the first and second major surfaces. Each opening has a respective area at the first surface, wherein the openings have a number density of 5 to 4600 openings per square inch, and wherein the total area of the openings is from 1 to 90 area percent, based on the combined total areas of the land portion and the openings. The porous abrasive layer is disposed on the first major surface of the porous backing. The porous abrasive layer comprises abrasive particles retained in a binder and has an abrading surface opposite the porous backing, and the second major surface of the porous backing and the abrading surface are in fluid communication through at least some of the openings. A method of making the porous coated abrasive article using flame perforation is also disclosed.
