An interference modulator (Imod) incorporates anti-reflection coatings and/or micro-fabricated supplemental lighting sources. An efficient drive scheme is provided for matrix addressed arrays of IMods or other micromechanical devices. An improved color scheme provides greater flexibility. Electronic hardware can be field reconfigured to accommodate different display formats and/or application functions. An IMod's electromechanical behavior can be decoupled from its optical behavior. An improved actuation means is provided, some one of which may be hidden from view. An IMod or IMod array is fabricated and used in conjunction with a MEMS switch or switch array. An IMod can be used for optical switching and modulation. Some IMods incorporate 2-D and 3-D photonic structures. A variety of applications for the modulation of light are discussed. A MEMS manufacturing and packaging approach is provided based on a continuous web fed process. IMods can be used as test structures for the evaluation of residual stress in deposited materials.

Photonic mems and structures

Methods and apparatus for computer-based control of light sources in a networked lighting system. In one example, a plurality of LED-based lighting systems are arranged as computer controllable “light strings.” Applications contemplated for such light strings include, but are not limited to, decorative and entertainment-oriented lighting applications (e.g., Christmas tree lights, display lights, theme park lighting, video and other game arcade lighting, etc.). Via computer control, one or more such light strings may provide a variety of complex temporal and color-changing lighting effects. In one example, lighting data is communicated in a given light string in a serial manner, according to a variety of different data transmission and processing schemes. In another example, individual lighting systems of a light string are coupled together via a variety of different conduit configurations to provide for easy coupling and arrangement of multiple light sources constituting the light string. In yet another example, small LED-based lighting systems capable of being arranged in a light string configuration are manufactured as integrated circuits including data processing circuitry and control circuitry for LED light sources, and are packaged along with LEDs for convenient coupling to a conduit to connect multiple lighting systems.

Methods and apparatus for controlling devices in a networked lighting system

Dynamically adapting the layout of a document to a particular output device. The layout of a document can be adapted to a particular output device so that the document fully utilizes the capabilities of the output device. A layout generator interrogates the output device to determine the capabilities of the output device. Based upon the capabilities of the output device, the layout generator selects a style sheet to accommodate the particular output device. The style sheet assigns values to format properties such as font properties, color and background properties, and text properties. The layout of the document is adapted to the particular output device by rendering the document on the output device using the values defined in the style sheet.

A display system includes an illumination source configured to produce visible and nonvisible radiation and to direct the visible and nonvisible radiation along an optical path; and a modulator disposed in the optical path configured to modulate the visible radiation to generate a visible image, and to modulate the nonvisible radiation to generate a nonvisible data stream.

A method of displaying an image with a display device including a plurality of display pixels includes receiving image data for the image, the image data including individual pixels of the image; buffering the image data and creating a frame of the image, the frame of the image including a plurality of columns and a plurality of rows of the pixels of the image; defining a first sub-frame and at least a second sub-frame for the frame of the image, image data of the second sub-frame being offset from image data of the first sub-frame by an offset distance of at least one pixel; and displaying the first sub-frame with a first plurality of the display pixels and displaying the second sub-frame with a second plurality of the display pixels offset from the first plurality of the display pixels by the offset distance.

Image display system and method

In an embodiment, an apparatus includes a projection subsystem to project an image-containing beam, and an image adjustment element. The image adjustment element is to cause adjustment of the image-containing beam in response to a detection of relative movement of the apparatus with respect to a reference object. A method includes determining whether substantial relative movement of a projection system has been detected, in an embodiment. When substantial relative movement has been detected, the method further includes producing control inputs, and altering operation of one or more image adjustment elements and/or altering image data in response to the control inputs, in an embodiment.

Image projection system and method

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.

Selectable Color Adjustment for Image Display

A method of automatically optimizing the controllable parameters related to producing printed material (40; 198; 229) on a hardcopy output device (10) is provided, along with a hardcopy output device (10) configured for implementing this method. Users require different types of printed objects to have different characteristics. Specifically, business graphics (45, 46; 204, 205; 238) need to be sharp and vivid, photographic images (48; 232, 236) should look realistic, and text (44, 44', 44''; 208; 234) must be black, crisp and clear. By extracting, analyzing and conditioning data (52) generated during a printing stream, the various regions of text (44, 44', 44''; 208; 234), graphics (45, 46; 204, 205; 238) and photographic images (48; 232, 236) on a sheet (15; 15'; 15'') are distinguished, characterized, and printed. The resulting hardcopy output (40; 198; 229) has a custom balancing of color which is pleasing to the human eye for each type of image printed, and may also have print characteristics tailored for the specific elements on the page.
