20080316567 | Illumination Source and Method Therefor - An illumination source and a method therefor. A light source includes a light circuit configured to process light and direct light, and a lighting element optically coupled to the light circuit to provide multiple colors of light. The light circuit propagates light using light guides. The use of light guides eliminates the use of free space optical elements, enabling the creation of more compact light sources. Furthermore, the use of light guides may enable the creation of light sources with fewer mechanical restrictions, thereby making the light sources potentially more reliable and less expensive. | 12-25-2008 |
20090059336 | System and Method for Display Illumination - System and method for increasing display brightness in laser illuminated display systems. An illumination source includes a light source to produce light, a disk having a set of lens elements arranged in a circular ring around a center of the disk, a motor coupled to the disk, and an external lens positioned in a light path of the coherent light source. As the disk rotates, the lens elements are moved sequentially through the light, angularly deflecting the light, which may be corrected by the external lens into a spatial deflection. The spatially deflected light may be used to simultaneously illuminate a surface with more than one color of light, thereby increasing the brightness of the light source. | 03-05-2009 |
20090147222 | Angle Diversity Antispeckling in Spot Displays - Improvement of speckling noise is discussed in which a central light beam received at a double-sided mirror is divided into a plurality of sub-beams. An intensity of these sub-beams decays from a second sub-beam to a last sub-beam of the plurality. Each sub-beam is also separated at the double-sided mirror by at least a first length, such as the coherence length or intrinsic divergence, and reflected toward a display screen. The configuration of the double-sided mirror focuses the sub-beams to converge with a first sub-beam on the display screen at different angles. The decreasing intensity and different angles of impact with the screen decreases the spatial coherence of the display light. The angle diversity and combination of multiple sub-beams having different intensities offers a non-time-averaging means to decrease speckle noise without downgrading the beam quality or display resolution. | 06-11-2009 |

20090009995 | OPTICAL ARCHITECTURE - An optical beam-shaping unit comprises a fly-eye lens for modifying light beams into modified light beams with desired profiles. The optical beam-shaping unit is especially useful in modifying collimated light from solid-state illuminators, such as laser sources. | 01-08-2009 |
20090190825 | Performance Analyses of Micromirror Devices - The invention provides a method and apparatus for evaluating the product quality and performances of micromirror array devices through measurements of the electromechanical responses of the individual micromirrors to the driving forces of electric fields. The electromechanical responses of the micromirrors according to the present invention are described in terms of the rotational angles associated with the operational states, such as the ON and OFF state angles of the ON and OFF state when the micromirror array device is operated in the binary-state mode, and the response speed (i.e. the time interval required for a micromirror device to transit form one state to another) of the individual micromirrors to the driving fields. | 07-30-2009 |
20140070875 | ROUTING TRACE COMPENSATION - A capacitive input device includes first and second pluralities of sensor electrodes disposed in a first region of a substrate. The first and second pluralities of sensor electrodes are substantially orthogonal to one another. The first region is configured to overlap a display screen. At least one routing trace is disposed in a second region of the substrate and is ohmically coupled to a sensor electrode of one of the first and second pluralities of sensor electrodes and also to a processing system. The second region comprises a non-display screen overlapping portion of the substrate. A compensation trace is disposed in the second region and ohmically coupled to the processing system. The compensation trace has substantially the same length as and is substantially parallel and proximate to the at least one routing trace. The compensation trace is not ohmically coupled to any sensor electrode located in the first region. | 03-13-2014 |
