Abstract: The invention concerns pointer tracking using a signal possessing an optical characteristic that is separately detectable from a projected display. An area of the projected display is sensed. Sensing is conducted with filtering for the separately detected optical characteristic.

Abstract: A method of projecting a compensated principal image may include projecting a principal image onto a surface and projecting an intended calibration image onto a calibration area of the surface. The intended calibration image may be projected when the principal image is not projected onto the calibration area. The calibration image displayed on the surface is received and compared to the intended calibration image to determine an observed difference. Projection of the principal image is modified based on the observed difference.

Abstract: A concentrated beam source for a projector includes a plurality of individually addressable light sources configured in a two-dimensional array and a beam concentrator. The beam concentrator is configured to receive light from the plurality of light sources and to produce a reduced beam of collimated light having a component representative of each light source. The reduced beam has cross-sectional dimensions smaller than cross-sectional dimensions of the two-dimensional array.

Abstract: A photon concentrator includes an imaging photon concentrator concentrating photons from a source to an image point and a non-imaging photon concentrator. The non-imaging photon concentrator (NIPC) has an entry aperture coupling to the imaging photon concentrator near the image point. The NIPC also includes an exit aperture wherein the entry aperture is larger than the exit aperture.

Abstract: A light modulator has one or more gratings and one or more MEMS actuators operable to move the gratings for selectively modulating light from an input light source. Certain embodiments have a plurality of blazed gratings arranged parallel to a plane and movable linearly parallel to the plane by MEMS actuators. Each of the gratings is individually blazed for light of a selected color such as red, green or blue. Associated with the gratings may be portions providing black and/or white outputs. An aperture spaced apart from the plane allows color(s) selected from an input white-light source to be directed to an output. An array of MEMS-actuated modulation devices provides a color spatial light modulator. Other embodiments have a grating adapted to be tilted by a MEMS actuator, either continuously through a range of angles or to a selected angle of a set of predetermined discrete angles, to direct selected wavelengths diffracted by the grating toward collection optics for a modulated light output.

Abstract: A method of one embodiment is disclosed that records one or more lengths of time a high temperature component of a device operates in accordance with a high-temperature policy. An action is performed in response to at least one of the lengths of time being greater than, corresponding threshold lengths of time.

Abstract: A method of fabricating a coupler for an optical fiber includes generating a beam of photonic energy and imaging a feature of the first mask onto the beam of photonic energy. The method also includes irradiating a substrate with the shaped beam, thereby ablating material from the substrate to create a feature. During the irradiating step, the shaped beam simultaneously irradiates the entire feature of the substrate.

Abstract: A method of displaying an image includes receiving image data for the image; buffering the image data for the image, including creating a frame of the image; defining a first sub-frame and at least a second sub-frame for the frame of the image; and displaying the first sub-frame and the second sub-frame, including synchronizing shifting a displayed image of the second sub-frame with displaying the second sub-frame.

Abstract: A display system may include an identifier configured to identify an image display condition associated with the display of an image produced by the display system, an apparatus configured to produce a plurality of differently colored images, and a display device. The images have color characteristics based on image information and the identified display condition. Differently colored images may be directed along associated portions of an optical path. The display device may be coupled to the apparatus and may be configured to display a color image formed of the differently colored images.

Abstract: A method of producing a display image comprises receiving image information representing an image to be displayed, producing an image formed of a plurality of images of different colors, and projecting the produced image along an optical path. The differently colored images have color intensities related to energy applied to a light source. A level of energy is applied to the light source during production of the image of one color that is different than the level of energy applied to the light source during production of the image of another color.

Abstract: A display system is configured to produce a color image formed of a plurality of differently colored images and may include at least one light source that directs light along an optical path, and at least one filter having a given optical filter characteristic. The display system may be selectively operable in a first state in which the optical path does not pass through a first filter during production of the plurality of differently colored images to form a color image having a first optical characteristic, and in a second state in which the optical path passes through the first filter during production of the plurality of differently colored images to form a color image having a second optical characteristic different than the first optical characteristic.

Abstract: Opto-mechanical adjustment based on sensing the label side of an optical disc is disclosed. The label side of the optical disc is first sensed with an opto-mechanical system. The opto-mechanical system is then adjusted, based on the label side of the optical disc as sensed, for future writing on the label side of the optical disc.

Abstract: Marking an optical disc based on information related to the data side thereof is disclosed. Information related to the data side of the optical disc is first determined. A marking based on the data side of the optical disc as has been read is then written with a laser to a label area on either the data side or the label side of the optical disc.
