  • Publication number: 20220113457
    Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

  • Publication number: 20220048286
    Abstract: Methods, apparatuses and systems for printing an ink pattern on a moving web via die cutting are provided. A die roll including an inked pattern of die blades contacts a substrate to cut or cleave the substrate surface. While the die blades withdraw from the substrate, at least some of the ink transfers from the die blades to the cut substrate to form an ink pattern.

  • Publication number: 20210325585
    Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses selectively located barriers to the adhesive regions. A structurally weak wavelength-selective material includes portions that contact the adhesive regions and break to remain in contact with the adhesive. The wavelength-selective material does not contact the adhesive regions covered by the barrier and is removed leaving a wavelength-selective film in a pattern at the adhesive regions.

    Abstract: Novel polymerizable ionic liquid compounds, and polymerizable compositions are described. The compositions comprise an acid functional monomer or acid-functional copolymer (or conjugate base thereof), and an imidazole compound (or conjugate acid thereof). The polymerizable compositions may be cast and cured to form a coating on a substrate, the coating capable of swelling on exposure to water so as to release from that substrate.

  • Patent number: 10537028
    Abstract: Electrically conductive patterns formed on a substrate are provided with a reduced visibility. A region of a major surface of the substrate is selectively roughened to form a roughened pattern on the major surface of the substrate. Electrically conductive traces are directly formed on the roughened region and are conformal with the roughened pattern on the major surface of the substrate.

  • Patent number: 9977154
    Abstract: A manufacturing system includes a sensing system that provides high-resolution feedback for web guiding and tension control. The system may be especially useful for web material that is manufactured to include micro-replicated structures with micron size scale. A micro-replication station forms a pattern of micro-replicated lenses on a web material. The sensing system illuminates a measurement area on the web material and detects an angular distribution of light exiting a set of the micro-replicated lenses within the first measurement area. A control system that adjusts at least one process control parameter of the transport system based on the detected angular distribution.

  • Patent number: 9440812
    Abstract: Methods and systems for determining longitudinal position of an elongated web are described. Sensors are used to detect one or more substantially continuous fiducial marks disposed longitudinally on the web. The sensors generate signals associated with the fiducial marks. A position detector receives the signals and determines a longitudinal position of the web using the sensor signals. The fiducial marks may be periodic fiducial marks, such as sine and/or cosine marks on the web and/or may be piecewise continuous marks. The coarse longitudinal position of the web can be determined based on periodically recurring features of the fiducial marks. The fine longitudinal position can be determined based on continuous portions of the fiducial marks between the periodically recurring features.

  • Patent number: 9057392
    Abstract: A web-handling machine frame, at least partially built from reconfigurable interconnected blocks having precision alignment points. From such blocks, modular equipment web-handling lines for web-handling operations can be constructed ad hoc with their shaft mounted web-contacting devices in tram without the need for separate alignment procedures.

  • Patent number: 8968629
    Abstract: An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers.

  • Patent number: 7830368
    Abstract: A keypad having a virtual floating image that appears to a user to be in a plane other than the apparent plane of the keypad surface. More particularly, the indicia on the keypad appear to float above or below the surface of the device. The keypad can be, for example, the keypad on a cell phone. For such an application there would be more than one array of indicia present on the keypad. For example, there might be ten arrays of indicia, which provide the numerals from 0 to 9 and two more arrays to provide virtual images of the * and # keys. In some embodiments, the keypad is integrated with an illumination source that light up the indicia. The present disclosure also provides a method of manufacturing a key pad with a virtual floating image.
