A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

An antireflection film substrate that is provided on a surface of a substrate includes a surface layer having an alumina hydrate as a main component. The surface layer has an uneven structure in which a volume proportion of the alumina hydrate per unit volume decreases in a direction from the substrate side to a surface side, and a period of apexes distributed on the uneven structure on the surface side is configured to be equal to or less than a wavelength of light of which reflection is to be suppressed.

Multilayer riblet applique and methods of producing the same are described herein. One disclosed example method includes applying a first high elongation polymer material to a web tool, where the web tool is to be provided from a first roll, and heating, via a first heating process, the first high elongation polymer material. The disclosed example method also includes applying a second high elongation polymer material to the first high elongation polymer material, and heating, via a second heating process, the second high elongation polymer material. The disclosed example method also includes applying, via a laminating roller, a support layer to the second high elongation polymer material.

A flexible flat cable (FFC) includes a first insulation layer, at least one pair of conductors, a plurality of low-k dielectric layers, two second insulation layers, and at least one shielding layer. The pair of conductors is located within the first insulation layer. Each pair of conductors includes a plurality of first conductors, and the first conductors are axially extending and arranged in parallel. The low-k dielectric layers are embedded in the first insulation layer. Each of the pair of conductors or each of the first conductors is covered and surrounded with one low-k dielectric layer. The two second insulation layers are located on two surfaces of the first insulation layer. The shielding layer is located on the two second insulation layers opposite to the first insulation layer.

A method produces labels having multiple sheets adhesively interconnected in a first surface area region of the basic label and lying loosely on top of each other in a second surface area region. After imprinting a carrier web, including imprinting an anti-adhesion layer in first surface area regions and a frame region, material webs are applied and imprinted to produce lowermost label sheets. An anti-adhesion layer is imprinted onto the last material web in third surface area regions lying between the first and/or second surface area regions and the frame region. After punching the material web between the third surface area regions and the first and/or second surface area regions, an outermost material web is applied and imprinted. By: punching a frame through all material webs, a waste matrix is severed, simultaneously forming an outermost sheet section in each third surface area region projecting laterally beyond the lowermost label sheets.

A reinforced water-resistant board includes a cover board with a reinforced water-resistant membrane applied to a surface of the cover board. The reinforced water-resistant membrane includes a primer layer, a reinforced membrane, a traffic coat, and a sealing layer. The primer layer is applied over the surface of the cover board. The reinforced membrane includes fleece soaked in a liquid resin and is applied over the primer layer. The traffic coat is bonded to the reinforced member. The sealing layer is applied over the traffic coat.

A cleaning card for cleaning a media transport device includes a substantially planar surface. At least one of the raised surface elements includes at least one scraping element. Optionally, at least one of the raised surface elements also include surface slits that cause asymmetrical deformation of the raised surface.

A cleaning pad for electronic devices includes a first layer and a second layer. The first layer has a top surface and a bottom surface. The second layer has a top surface and a bottom surface removably attached to the top surface of the first layer. The bottom surface of the second layer includes an interior portion fabricated from a cleaning material for cleaning a display of an electronic device, and an exterior portion surrounding the interior portion and fabricated from an adhesive material. The interior portion of the bottom surface of the second layer is sealed between the exterior portion of the bottom surface of the second layer and the top surface of the first layer.

The inventive disclosures are directed to a factory-controlled process for making improved, risk-optimized commercial-building waterproofing systems. The improved waterproofing-panel systems also include improved intrinsic leak-detection capabilities.
