| 20090067151 | LIGHT GUIDE WITH FLEXIBILITY AND DURABILITY - A flexible light guide including a material having a tensile modulus of about 1 MPa to about 70 MPa, a T | 03-12-2009 |
| 20090175050 | PROCESS FOR MAKING LIGHT GUIDES WITH EXTRACTION STRUCTURES AND LIGHT GUIDES PRODUCED THEREBY - A process comprises imagewise exposing at least a portion of a photoreactive composition to light sufficient to cause simultaneous absorption of at least two photons/thereby inducing at least one acid- or radical-initiated chemical reaction where the composition is exposed to the light, the imagewise exposing being carried out in a pattern that is effective to define at least the surface of a plurality of light extraction structures. Each one of the array of light extraction structures has at least one shape factor; the shape factor may vary across the array. At least one light extraction structure may have the geometric configuration of a truncated asphere. | 07-09-2009 |
| 20090279321 | PROCESS FOR MAKING LIGHT GUIDES WITH EXTRACTION STRUCTURES AND LIGHT GUIDES PRODUCED THEREBY - A process comprises imagewise exposing at least a portion of a photoreactive composition to light sufficient to cause simultaneous absorption of at least two photons, thereby inducing at least one acid- or radical-initiated chemical reaction where the composition is exposed to the light, the imagewise exposing being carried out in a pattern that is effective to define at least the surface of a plurality of light extraction structures. | 11-12-2009 |
| 20090285543 | PROCESS FOR MAKING LIGHT GUIDES WITH EXTRACTION STRUCTURES AND LIGHT GUIDES PRODUCED THEREBY - A process comprises imagewise exposing at least a portion of a photoreactive composition to light sufficient to cause simultaneous absorption of at least two photons, thereby inducing at least one acid- or radical-initiated chemical reaction where the composition is exposed to the light, the imagewise exposing being carried out in a pattern that is effective to define at least the surface of a plurality of light extraction structures. | 11-19-2009 |
| 20100288614 | LIGHTGUIDES HAVING LIGHT EXTRACTION STRUCTURES PROVIDING REGIONAL CONTROL OF LIGHT OUTPUT - Lightguides, devices incorporating lightguides, and processes for making lightguides are described. A lightguide includes light extractors arranged in a pattern on a surface of the lightguide. The pattern of light extractors is arranged to enhance uniformity of light output across a surface of the lightguide and to provide enhanced defect hiding. The efficiency of the light extractors is controlled by a shape factor. The areal density of the light extractors across the surface of the lightguide may be substantially constant or may decrease along the direction of propagation of light from the light source. | 11-18-2010 |
| 20110243500 | LIGHT GUIDES HAVING ENHANCED LIGHT EXTRACTION - Lightguides, devices incorporating lightguides, processes for making lightguides, and tools used to make lightguides are described. A lightguide includes light extractors arranged in a plurality of regions on a surface of the lightguide. The orientation of light extractors in each region is arranged to enhance uniformity and brightness across a surface of the lightguide and to provide enhanced defect hiding. The efficiency of the light extractors is controlled by the angle of a given light extractor face with respect to a light source illuminating the light guide. | 10-06-2011 |

| 20080218566 | Metallized print head container and method - Various embodiments of a metallized print head container and method are disclosed. | 09-11-2008 |
| 20080266370 | Compact Ink Delivery In An Ink Pen - In one embodiment an ink pen for an inkjet printer includes: an ink filter chamber; a pressure regulator chamber downstream from the ink filter chamber along a path of ink flow through the pen; a pressure regulator in the pressure regulator chamber; a filter in the ink filter chamber; an inlet to the ink filter chamber upstream from the filter along the ink flow path; and an outlet from the ink filter chamber to the pressure regulator chamber downstream from the filter along the ink flow path such that ink flowing from the inlet to the outlet passes through the filter. In another embodiment a method implemented in an ink delivery system for an inkjet ink pen includes: chambering ink in the pen; filtering the chambered ink; and then regulating the pressure of filtered ink. | 10-30-2008 |
| 20090091606 | Flow Control In An Ink Pen - In one embodiment a pressure regulator for an ink pen includes: a diaphragm between a lower pressure region and a higher pressure region, the diaphragm movable toward the lower pressure region in response to an increase in a pressure difference across the diaphragm; a valve operative between an open position in which ink may flow into the lower pressure region and a closed position in which ink may not flow into the lower pressure region; a first lever rotatable on a first fulcrum in response to movement of the diaphragm toward the lower pressure region; and a second lever connected to the valve, the second lever rotatable on a second fulcrum in response to rotation of the first lever to move the valve from the closed position to an open position. | 04-09-2009 |
| 20110120572 | FLUID SUPPLY - A fluid supply includes a container ( | 05-26-2011 |
| 20110197991 | FLUID SUPPLY CAP - A fluid supply includes a container, a bag within the container and a cap. The cap provides a fluid interface in communication with an interior of the bag and a pressurization interface in communication with an interior of the container adjacent an exterior of the bag. The pressurization interface has a channel that concentrically extends about the fluid interface. | 08-18-2011 |
| 20120008882 | FLUID HANDLING SYSTEM - A fluid handling system includes a valve assembly within a needle that is movable from a closed state to an open state against a bias while engaging and moving a valve stem of a fluid supply from a closed state to an open state. | 01-12-2012 |
