| 20080199188 | Interferometric communication - Embodiments of interferometric communication are disclosed. | 08-21-2008 |
| 20080247012 | VARIABLE OPTICAL PHASE MODULATOR - A variable optical phase modulator includes an array of movable, micro-electromechanical conductive plates. Each conductive plate has a substantially reflective surface, and is responsive to an applied voltage to move the conductive plate normal to a plane of the array to a predetermined distance with respect to other conductive plates in the array. The phase modulator also includes a voltage controller associated with the array of conductive plates. The voltage controller supplies a voltage to at least one of the movable conductive plates to move and position the movable plate to change the phase of electromagnetic energy reflected from the reflective surface with respect to the phase of electromagnetic energy reflected from other conductive plates in the array. | 10-09-2008 |
| 20080247017 | SYSTEM AND METHOD FOR PRINTING A HOLOGRAM - A system and method for printing a hologram are disclosed. The method includes the operation of transmitting a laser light beam. The laser light beam can be split into an object beam and a reference beam. Phase information can be added to the object beam using a spatial phase modulator to form a phase controlled object beam. The reference beam and the phase controlled object beam can be directed to a predetermined location on a holographic media to enable the reference beam and the phase controlled object beam to form an interference pattern on the holographic media. | 10-09-2008 |
| 20080252690 | Micro Writing And Reading - In one embodiment, a printing device includes: a print engine configured to apply marking material to print media; a laser writer configured to expose the print media to a laser beam of sufficient energy to change the reflectivity of exposed portions of the print media; a media path along which the print engine may apply marking material to print media in a macro printing zone and along which the print media may be exposed to a beam of light emitted by the laser writer in a micro printing zone; and an electronic controller operatively connected to the print engine for selectively applying marking material to the print media and to the laser writer for selectively exposing the print media to a laser beam. | 10-16-2008 |
| 20080261809 | Encoder spokes detection prior to forming image on optically writable label surface of optical disc - Whether an optically writable label surface of an optical disc is suitable for having an image formed thereon is determined. A detectable number of encoder spokes on a control feature area of the optical disc is counted as the optical disc is rotated. Where the detectable number of encoder spokes is other than a predetermined value, an error condition with respect to the optically writable label surface of the optical disc is indicated. | 10-23-2008 |
| 20090078771 | Method and System for Using an Optical Sensor Array to Control a Labeling Device - A method for using an optical sensor array to control a labeling device includes scanning a surface texture of an imageable media with the optical sensor array, collecting surface data corresponding to the surface texture of the imageable media, and controlling the labeling device in response to the surface data. | 03-26-2009 |
| 20100296099 | OPTICAL DEVICE - An optical device includes a photodetector, a Fabry-Perot interferometer and an analyzer. | 11-25-2010 |
| 20110175959 | THERMAL FLUID-EJECTION DEVICE DIE - A die for a thermal drop-on-demand fluid-ejection device includes thermal firing resistors, low-side switches, and high-side switches. The thermal firing resistors are organized over resistor groups such that each thermal firing resistor is located within only one of the resistor groups. The resistor groups are lesser in number than the thermal firing resistors. Each thermal firing resistor has a first end and a second end. The low-side switches are equal in number to the thermal firing resistors. Each low-side switch connects the second end of a corresponding thermal firing resistor to a low voltage. The high-side switches are equal in number to the resistor groups. Each high-side switch connects the first ends of the thermal firing resistors of a corresponding resistor group to power providing a voltage greater than the low voltage. | 07-21-2011 |
