Abstract: A method for making a dental appliance configured to position at least one tooth of a patient includes printing a hardenable liquid resin composition on a major surface of a polymeric material to form a pattern of discrete unhardened liquid regions thereon; at least partially hardening the unhardened liquid regions to form a corresponding array of structures on the major surface of the polymeric material, wherein the structures have a characteristic cross-sectional dimension of about 25 microns to about 1 mm, and a feature spacing of about 100 microns to about 2000 microns; and forming a plurality of cavities in the polymeric material to form the dental appliance including an arrangement of cavities configured to receive one or more teeth.

Abstract: An optical system is disclosed and includes an optical sensor configured to receive light and form an image. The optical system further includes a microlens film including a structured first major surface opposite a second major surface, the structured first major surface includes a regular array of spaced apart microlenses arranged across a width and a length of the microlens film and each microlens has an effective imaging area and configured to form an image onto the optical sensor. A light absorbing layer is disposed on the array of spaced apart microlenses and reduces the effective imaging area of each microlens by at least 10%. A display panel, the optical sensor, the microlens film and the display plane are substantially co-extensive with each other along the width and length of the microlens film.

Abstract: Diagnostic devices for quantitative or qualitative analysis of a sample fluid including an analyte include at least two portions made from a hydrophilic material. The planar portions are stacked on each other and each occupy a different and substantially parallel plane to form a three-dimensional structure. At least one of the planar portions includes a hydrophobic region formed by applying a low surface energy material that extends through a thickness of the substrate portion from a first major surface to a second major surface thereof. The hydrophilic regions in the overlying substantially parallel substrate portions can be aligned with each other such that a fluid is passively transported between adjacent hydrophilic regions to provide a sample flow path between adjacent substrate portions.

Abstract: A method includes placing an electronic device on a pliable mating surface on a major surface of a mold such that at least one contact pad on the electronic device presses against the pliable mating surface. The pliable mating surface is on a microstructure in an arrangement of microstructures on the major surface of the mold. A liquid encapsulant material is applied over the electronic device and the major surface of the mold, and then hardened to form a carrier for the electronic device. The mold and the carrier are separated such that the microstructures on the mold form a corresponding arrangement of microchannels in the carrier, and at least one contact pad on the electronic device is exposed in a microchannel in the arrangement of microchannels. A conductive particle-containing liquid is deposited in the microchannel, which directly contacts the contact pad exposed in the microchannel.

Abstract: Methods of passivating an adhesive via printing an ink onto a release liner, and adhesive articles or products made by the same are provided. An ink pattern is printed onto a release liner to form a pattern of features. The features are at least partially embedded in an adhesive layer such that when the release liner is peeled from the adhesive layer, the passivation features remain with the layer of adhesive to form selected areas having adjusted adhesive functionality. Articles including the passivated adhesive on a release liner are also disclosed.

Abstract: Methods and apparatuses for applying liquid coatings are provided. A first roll (14), a second roll (16), and a nip (146) formed between the first and second rolls are provided. A coating liquid (22) is supplied to the nip. The coating liquid is smoothed, via the nip, into a substantially uniform layer (22a) of liquid coating which is transferred to a substrate (12). The second roll (16) includes a thin metal shell (40) and a resilient layer (30), the thin metal shell encases the resilient layer therebeneath, and the thin metal shell is capable of deflecting in unison with the resilient layer such that the thin metal shell is elastically deformable at the nip when in contact with the first roll (14).

Abstract: A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm≤L2−L1≤50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.

Abstract: Methods and apparatuses for screen or stencil printing a pattern on a substrate are provided. The substrate (2) has its major surface in contact with a first major surface (112) of a stencil shell (111) having apertures (116). A coating material is disposed onto the second major surface (114) of the stencil shell (111) to flow through the apertures (116) to contact the substrate (2), where the coating material is at least partially cured. The substrate (2) is separated (C) from the first major surface (112) of the stencil shell (111) after the curing (142) and a pattern (42) of the at-least-partially-cured coating material is formed on the substrate (2).
