  • Patent number: 10599722
    Abstract: A computerized method of comparing documents includes a computing device: receiving a source document via a first automated document feed channel; receiving a target document via a second automated document feed channel; pre-processing the source document using a first comparison data structure operating on the computing device, thereby producing a pre-processed source document having a text array including text from the source document; pre-processing the target document using a second comparison data structure, thereby producing a pre-processed target document having a text array including text from the target document; determining, using a document comparison engine operating on the computing device, a set of differences between the pre-processed source document and the pre-processed target document with respect to a set of pre-specified criteria; and generating, a summary of the set of differences between the pre-processed source document and the pre-processed target document.

  • Patent number: 6407034
    Abstract: A thermally printable thermoplastic media includes a thermoplastic material having a thermally activated composition incorporated therein. The thermally activated composition includes a leuco-dye, a color developer, and a reaction promoter. The printable media preferably has a thickness of from about 0.5 to about 1.5 mils to provide a roll with a longer length than a conventional paper roll, thereby increasing the amount of printable media which can be contained on a roll. The thermally printable thermoplastic media is manufactured by combining a thermoplastic material and a thermally activated composition, melting the combined thermoplastic material and thermally activated composition and forming a film from the combined thermoplastic material and thermally activated composition, typically by extrusion. To prevent pre-imaging or initiation of a thermo-chromogenic reaction from the heat involved in extrusion, the extrusion is preferably carried out in an oxygen-free environment.

  • Patent number: 6284177
    Abstract: A printable tape of a thermoplastic material for use in cash registers to improve the efficiency of the check out process and enhance the post consumer recyclability of the plastic bags used by the stores. The tape comprises a thermoplastic material, typically polyethylene or polypropylene, a pigment to provide sufficient opacity such that printing on the printable media is readable and a sufficient amount of a matting agent to improve the printability of the printable media.

  • Patent number: 5236749
    Abstract: A blister packaging system is disclosed that is a sheet/film or sheet/sheet package designed to be easily recycled and may be of materials that have a high recycled content without degradation in performance. The blister package is composed of a thermoformed or vacuumformed front blister made from polyethylene terephthalate (PET), PET-G or R-PET which may have a significant pre or post-consumer recycled content sealed to a back film or sheet made from polyethylene which may also have a significant pre or post consumer recycled content. The film or sheet back may be printed on either or both sides and is coated on one side with an adhesive which bonds to the blister in the filling/sealing process.

  • Patent number: 4587158
    Abstract: A label system is disclosed that is deformable and is useful for the decoration or marking of squeezable bottles or other flexible substrates. The label system is composed of a film of low or medium density polyethylene which is corona treated to accept print or decorative resin and certain curable pressure sensitive adhesives, and is affixed by the adhesive to bottles or other substrates in a manner that the label conforms to the shape of the surface of the bottle. The label deforms and recovers in essentially a permanent manner without wrinkling, cracking, tearing or being otherwise defaced due to separation or destructive fracturing of the label-substrate system.
