Abstract: This disclosure features embedded electrooptical displays such as liquid crystal displays and methods of making the same. The displays are embedded in light curable material on one or both sides thereof. Processes for embedding the displays include injection molding and continuous roll-to-roll processing. The light curable material forms a protective covering over the display. Electrical interconnects connected to electrodes of the display can protrude from the protective layer. Once the display is embedded it can resist contact with moisture and mechanical damage. The protective layer can be clear or it can contain additives such as pigments or additives for UV protection. The embedded display with the protective layer may be molded into different shapes during the embedding process or thermoformed after the embedding process into different shapes.

Abstract: A mute for a horn-type musical instrument is disclosed. The mute having a freely resonating body including an opening therein to permit air flow into the body, the body having n number of first facets wherein n is an integer from 3 to 99 and having o number of second facets wherein o is an integer from 1 to 99. The mute changes the timbre of the sound generated by the instrument, yet maintains the majority of the volume of sound prior to placement of the mute into the bell.

Abstract: The production of liquid crystal displays (LCDS) on plastic substrates is desirable over glass substrates so that the finished product is thinner, lighter, and more robust. Plastic substrates can enable the use of new and different processing techniques which are not possible on glass such as roll-to-roll processing. This invention discusses an advancement which is laser cutting a plastic substrate and display layer. One aspect of the invention is laser cutting and welding together two or more plastic substrates and LCD layer therebetween from a larger sheet or roll of plastic LCDs.

After the reflective layer is constructed, a step of constructing an optical element layer follows, including a step of forming an array of microstructures in the optical element layer. Next, the array of microstructures is abutted against the reflective layer. Heat and pressure are then applied to the optical element layer to puncture the reflective layer and penetrate a predetermined distance through the reflective layer. Sub-assemblies are also defined, wherein optical elements are coupled to prevent light loss.

Abstract: The present invention relates to a type of optical fiber grating having an azimuthal refractive-index perturbation. The optical fiber includes a fiber grating that has a plurality of grating elements formed therein. At least one of the grating elements has a spatially varying index of refraction that varies azimuthally about the centerline of the optical fiber. The fiber grating acts as a band-stop optical spectral filter. In addition, since fiber-cladding modes are weakly-guided modes, their power can be easily dissipated by scattering, bending, stretching, and/or rotating the optical fiber. Multiple configurations of these gratings within an optical fiber are given. Methodologies are given for the fabrication of these gratings. Devices are presented which can dynamically attenuate, tune, switch, or modulate the wavelength spectral characteristics of an optical signal.

Abstract: A method of making an article (10) having a desired microembossed architecture (18). In this method, a substrate (40) having an exterior surface (42) is sealed within a pouch (36) having an interior surface (32) with a microstructure (34) corresponding to the desired microembossed architecture (18). The pouch (36) is evacuated, whereby the microstructure (34) contacts the exterior surface (42) of the substrate (40) sealed therein. The evacuated pouch (36) is then thermally processed so that the microstructure (34) embosses at least a region of the exterior surface (42) of the substrate (40) so as to form the desired microembossed architecture (18).
