  • Power distribution in a thermal ink jet printhead
    Patent number: 8444255
    Abstract: A thermal inkjet printhead may include a substrate and a resistive layer. A thermal resistor may be formed in the resistive layer. A first metal layer may be between the substrate and a resistive layer having a thickness to form a power bus. A dielectric layer may be between the first metal layer and the resistive layer.
    Type: Grant

  • Projection screen
    Patent number: 7293879
    Abstract: A projection screen for use in a projection system is described. In an embodiment of the present invention, a projection system includes a projector and a projection screen. The projector is configured to project an image composed of visible light in one or more ranges of wavelengths. The projection screen has a plurality of sub-pixels that reflect and/or transmit the one or more ranges of wavelengths to display the image and absorb visible wavelengths of light in at least one other range not included in the one or more ranges. One or more spaces are defined between adjacent sub-pixels that reflect and/or transmit the one or more ranges and the at least one other range.

  • Stereoscopic imaging
    Publication number: 20060012753
    Abstract: A stereoscopic imaging method includes intercepting a light flux projecting an image frame having first and second image cells. The light flux is split so that a first portion of the light flux projects the first image cell along a first light path and a second portion of the light flux projects the second image cell along a second light path. The first and second light paths are selected so that the first and second portions of the light flux can cast superimposed images on a target.
