20080204854 | Electrostatically-Controlled Diffraction Gratings Using Ionic Electrophoresis - A diffraction grating for which the intensity and/or direction of the diffracted light is electronically modulated using the electrophoresis of an index-modifying species. Index-modifying dye ions are dissolved in an electrophoretic medium maintained adjacent the diffraction grating. Application of a voltage across the medium moves many of the ions into the region adjacent the grating such that the ions absorb the incident light or otherwise modify the local index of refraction so as to change the optical characteristics of the diffracted light. Application of an opposite voltage across the medium moves many of the ions away from the grating, allowing light rays to diffract in a different manner when encountering the grating. | 08-28-2008 |
20090115004 | SURFACE ACOUSTIC WAVE SENSOR ASSEMBLIES - The invention is directed to a surface acoustic wave sensor assembly that makes use of a Z-axis conductive layer, such as a Z-axis conductive elastomer, or the like. In particular, a Z-axis conductive elastomer couples a circuit layer to a surface acoustic wave (SAW) sensor in order to form a SAW sensor assembly. For example, a plurality of electrical contacts of the circuit layer can be coupled to a plurality of electrodes of the SAW sensor via the Z-axis conductive elastomer. The Z-axis conductive elastomer provides electrical coupling between the electrical contacts and the electrodes, and also forms a hermetic barrier between the circuit layer and the SAW sensor. In addition, elastic properties of the Z-axis conductive elastomer may reduce pressure exerted on the SAW sensor during use. | 05-07-2009 |
20090249969 | PRINTER HAVING INCREASED SOLUTION VOLUME OF PRINTING AND INCREASED PRINT QUALITY AND SPEED - A printer for digital printing in which ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the ink from the wire and carries it toward the substrate. The wire has features to increase a solution volume of the ink on the wire. The ink is applied to the substrate in vector mode to form well defined fine lines an image and a raster mode to form wider lines less well defined than the fine lines. | 10-08-2009 |
20090316058 | FILMS ENABLING AUTOSTEREOSCOPY - A stereoscopic 3D liquid crystal display module includes a liquid crystal display panel and a directional backlight positioned to provide light to the liquid crystal display panel. A double sided prism film is disposed between the liquid crystal display panel and the directional backlight. The prism film includes a first surface having a series of cylindrical lenses adjacent the liquid crystal display panel and a second surface, opposite the first surface, having a series of non-contiguous prisms adjacent the directional backlight. Each of the non-contiguous prisms is separated from adjacent prisms by a transmissive flat portion or an opaque portion. | 12-24-2009 |
20100141869 | PASSIVE AND HYBRID DAYLIGHT-COUPLED BACKLIGHTS FOR SUNLIGHT VIEWABLE DISPLAYS - A passive daylight-coupled display having an LCD panel, a diffuser, and a curved reflector behind the LCD panel. For passive backlighting, the diffuser transmits daylight to the reflector, which reflects the daylight to the LCD panel and provides for substantially uniform distribution of the daylight on the LCD panel for backlighting it. A hybrid display includes both a passive backlight and an active backlight for providing backlighting from an active light source. | 06-10-2010 |
20100265584 | RETROREFLECTING OPTICAL CONSTRUCTION - Retroreflecting optical constructions are disclosed.

20140239555 | APPARATUS AND METHOD FOR PRODUCING TWO-SIDED PATTERNED WEB IN REGISTRATION - An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers. | 08-28-2014 |
