Abstract: Optical articles that include adhesive lightguides having resonant circuits and one or more light sources are described. More particularly, optical articles having resonant circuits that, upon a triggering event, cause the one or more light source to emit light into the adhesive lightguide such that light is transported within the lightguide by total internal reflection are described. Additionally, applications and embodiments that include such optical articles are described.

Abstract: A display apparatus includes an autosteroscopic liquid crystal display panel having a frame response time of less than 10 milliseconds, and a backlight positioned to provide light to the autosteroscopic liquid crystal display. The backlight includes a right eye solid state light source and a left eye solid state light source capable of being modulated between the right eye solid state light source and a left eye solid state light source at a rate of at least 90 Hertz.

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.

Abstract: A method for electroplating of a substrate traveling in a substrate direction. The method comprises directing a first fluid stream and a second fluid stream respectively across the first and second width portions of the substrate. The first and second fluid streams do not flow substantially cocurrently with nor countercurrently to the substrate direction.

Abstract: A sleeve for protecting and reinforcing a fusion splice of two or more optical fibers. The fusion splice protector includes a heat-shrinkable sleeve adapted to surround the fusion splice and adjacent portions of the fused optical fibers, a stress-relieving support element adjacent the fusion splice, and a hot-melt adhesive contained within the sleeve for retaining the support element adjacent a longitudinal section of the sleeve. The support element is designed to impart varying elasticity along a length of the sleeve such that the fusion splice protector is more rigid at the central portion of the sleeve member than at its ends. This may advantageously be achieved by providing a support element having a cross-sectional profile which varies along the length of the sleeve. The support element is preferably constructed of a polymer or polymer blend, most preferably one having a coefficient of thermal expansion which is approximately equal to the coefficient of thermal expansion of the optical fibers.

Abstract: An optical fibre has a light emitting region. In the light emitting region are reflecting surfaces, at least one of which has a cross sectional area less than that of the fibre. Light striking the reflecting surfaces will be reflected out of the fibre.

Abstract: An optical recording element in which information can be recorded and read directly afterwards by means of laser light, the element comprising, as a recording medium, a dye, which is not capable of being isomerized due to light, dissolved or dispersed in a binder, the binder comprising a thermally cured organic material composed of non-metallic elements only, and having a cross-linked three-dimensional network structure. The thermally cured binder provides improved stability to repeated read.

Abstract: An optical fibre comprising a core coated with a cladding composition having a lower refractive index than the core, said cladding composition comprising a fluorinated mono-acrylate, a polyfunctional cross-linking acrylate being difunctional or higher, and a photoinitiator, said cladding composition comprising less than 0.3% by weight of a mono- or polyfunctional thiol and being cured or cross-linked.

Abstract: A polymeric tetra-aryl polymethine dye of the general formula ##STR1## in which: A comprises a conjugated chain of carbon atoms having an equal number of double and single bonds,each R independently represents an alkyl group of 1 to 4 carbon atomsR.sup.1 represents --NR.sub.2 or ##STR2## and X.sup.- represents an anion.The dyes are suitable for use as recording media in optical recording elements in which information may be recorded and read directly afterwards by means of laser light.

Abstract: An optical data storage element in which information can be recorded and read directly afterwards by means of laser light comprising, as a recording medium a dye dissolved or dispersed in a binder in which at least 25% by weight of the binder comprises a polymer in which at least 50% of the units have the general formula: ##STR1## in which: R.sup.1 to R.sup.8 are independently selected from hydrogen, an alkyl group of up to 12 carbon atoms, an aromatic group of up to 12 carbon atoms, halogen, ether, carboxylic acid, ketone, nitro, amino and hydroxy groups of any two adjacent groups of R.sup.1 to R.sup.8 may comprise the necessary atoms to complete a carbocyclic or heterocyclic ring, and there are at least 10 units of formula (I) within the polymer chain.The dye-polymer system possesss high sensitivity acceptable CNR and particularly good stability to repeated read.
