Abstract: A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film 200. The first element of the multilayer polymer optical film is a core layer 202 that is made up of a multilayer optical stack. The multilayer optical stack of core layer 202 includes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer 204 (for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layer 204 may include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical film 200 may optionally also include an adhesive layer 208 that is positioned between the core layer 202 and a surface onto which the multilayer polymer optical film is to be adhered.

Abstract: A composite article having a conductive layer on at least a portion of a flexible substrate. Electrical connectivity between various portions of the substrate can be obtained through this conductive layer. The conductive layer comprises a conductive surface, and there is a patterned layer on at least a portion of a first region of the conductive surface. The patterned layer comprises a conductive material having a surface roughness, and is in electrical contact with the conductive surface. An overcoat layer is present on at least a portion of the first region, such that the overcoat layer has a thickness less than the surface roughness, such that the conductive layer within the first region is covered by the overcoat layer, and such that at least a portion of the patterned layer substantially protrudes above the overcoat layer. The protruding portion permits electrical contact with the patterned layer, and via the conductive layer to other parts of the patterned layer and/or electrically conductive connectors to external electronic devices. Methods for forming the composite article are also disclosed. Methods of making such composite articles are also disclosed.

Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

Abstract: A touch panel includes a touch sensor having a dielectric core layer disposed between first and second piezoelectric layers. Each piezoelectric layer comprises a poled piezoelectric polymer. The touch sensor further includes at least a first set of individually addressable electrodes disposed over the first piezoelectric layer and at least one second electrode disposed over the second piezoelectric layer. Circuitry is coupled to the first set of electrodes and the second electrode. The circuitry is configured to detect a change in an electrical signal of at least one electrode of the first set of electrodes referenced to the second electrode in response to a touch applied to the touch surface of the touch sensor.
