    Abstract: An enhanced color messaging instrument gauge assembly is disclosed having a lens with one or more surface interruptions. A lens covering an instrument cluster transmits colored light longitudinally from at least one light source near its edge. Light encountering the surface interruption causes the surface interruption to illuminate. In one embodiment, different colored light can be coordinated with activation of symbols on the instrument cluster to attract the attention of an operator to an abnormal operating condition or to reinforce other information being communicated to the operator on the instrument cluster.

  • Patent number: 7468786
    Abstract: The present invention is an engraved gemstone viewer for viewing a flat, smooth surface of a gemstone that has been micro or nano etched with an inscription such as an identification number. The gemstone is mounted on a piece of jewelry or can remain unmounted when placed inside or otherwise received by the viewer. A source of light directs a light beam toward a magnifying lens coated with a reflection enhancing coating. The lens reflects the light beam along a path incident to the surface of the gemstone containing the inscription. The smooth flat gemstone surface spectrally reflects the light beam along a path back toward the magnifying lens, which produces a viewable light image that reveals the inscription. The inscription is shown as a dark or lightless region of the light image.

  • Patent number: 6870695
    Abstract: An optical configuration suited to the monitoring of a process flow through the wall of a containment vessel for producing a high-quality, high-NA sample focus and reduced residual positive spherical aberration. The invention includes an optical path with a window extending through, and sealed to, the wall of the containment vessel, and an optical surface disposed in the optical path associated with minimizing aberration, increasing numerical aperture, or both. The window has a surface facing into the process flow and a surface facing away from the process flow and, the surface facing away from the process flow is associated with minimizing aberration or increasing numerical aperture. A lens is disposed outside the containment vessel and in the optical path, with the surface of the window facing the lens being substantially spherical. With such an arrangement, the light rays of the optical path are generally normal to the surface of the window facing the lens.

  • Publication number: 20040085633
    Abstract: The present invention concerns the structure of and methods of constructing indicating instruments with slim profiles. The indicating instrument comprises a meter movement and a circuit board. The main body of the meter movement is situated in an aperture in the circuit board. With this placement, the front end of the body of the meter movement extends a distance in front of the circuit board and the back end of the meter movement body extends a distance behind the circuit board. Through appropriate selection and arrangement of any components on the circuit board, the circuit board can be constructed such that none of its components extend beyond the distance that the meter movement extends on either side of the circuit board. In this manner the space needed for the meter movement and the circuit board and its components collapses into the same area. A light plate may be added to the circuit board and meter movement. The light plate provides a structural framework for the indicating instrument.
