20080284984 | Projection Device with a Folded Optical Path and Wire-Grid Polarizer - A folded projection display system includes a wire-grid polarizer placed immediately behind the system's imaging screen. The display system includes an image projector that projects an image beam containing light of a predetermined linear polarization toward the imaging screen. The wire-grid polarizer reflects the light in the image beam away from the screen. The reflected image beam then encounters a ¼-wavelength achromatic retarder that converts the linear polarization to circular polarization. The image beam next hits a mirror that reflects the light back through the ¼-wavelength achromatic retarder, which converts the circular polarization back to linear polarization, with the polarization director rotated 90 degrees from the original polarization direction. The wire-grid polarizer then allows the light to pass through to the image screen. | 11-20-2008 |
20090168171 | MULTILAYER WIRE-GRID POLARIZER WITH OFF-SET WIRE-GRID AND DIELECTRIC GRID - A multilayer wire-grid polarizer for polarizing light includes a stack of thin film layers disposed over a substrate, including a wire-grid array of elongated metal elements having lengths longer than a wavelength of the light and a period less than half the wavelength of the light. One of the layers can include a thin film layer with a refractive index greater than a refractive index of the substrate. One of the thin film layers can include a dielectric array of non-metal elements. | 07-02-2009 |

20100182894 | OPTICAL DATA STORAGE MEDIA CONTAINING AN ENCAPSULATED DATA LAYER - Optical information media containing encapsulated data layers are disclosed. Selective layering of materials in inner radial, middle radial, and outer radial zones allows for the faces and edges of at least the data layers to be encapsulated by other materials, resulting in increased resistance to harmful environmental agents such as oxygen and moisture. | 07-22-2010 |
20100221481 | OPTICAL DATA STORAGE MEDIA CONTAINING SUBSTANTIALLY INERT LOW MELTING TEMPERATURE DATA LAYER - Optical information media that contain a data layer material that is substantially inert to oxidation and has a defined melting point range are disclosed. The inertness to oxidation and melting point range make the media particularly attractive for long-term information storage. | 09-02-2010 |

20110080819 | SYSTEMS AND METHODS FOR RELIABILITY TESTING OF OPTICAL MEDIA USING SIMULTANEOUS HEAT, HUMIDITY, AND LIGHT - Methods and systems for the rapid evaluation of optical media reliability are disclosed. Simultaneous exposure of optical media to heat, humidity, and light has been found to be an effective test to differentiate more stable media from less stable media in a reasonable amount of time. | 04-07-2011 |
20110110209 | OPTICAL INFORMATION MEDIA, SYSTEMS, AND METHODS FOR PROVIDING UBIQUITOUS READ AND SELECTIVE WRITE - An optical information media, system, and method for providing ubiquitous reading and selective writing is disclosed. By placing data structures representing a nonstandard book type in byte “0” of the media, the media is made universally bootable and universally readable in substantially any DVD drive. On the other hand, data structure representing a version code or disc category is placed in byte “0” or another byte of the control data zone in order to identify the media and enable writing in select drives. The version code and/or disc category identifies the media and calls for one or more write strategies configured for writing to the particular media. When the media is a permanent storage media, loss of data can be avoided, ubiquitous read can be achieved, and selective write in predetermined drives can be achieved resulting in a robust system and method of storing and retrieving data. | 05-12-2011 |
