  • Publication number: 20080180797
    Abstract: A reflective display screen comprises a first component surface responsive to absorb low level ambient light from above the screen and a second surrounding component surface responsive to light of high intensity from an image source. The first component surface is graphically formed to represent a fixed permanent image within the screen viewable only in ambient overhead lighting and without incidence of the high intensity light from the image source. Other embodiments include a method of displaying a permanent, fixed image and a method of making a display screen.

  • Patent number: 7349155
    Abstract: A reflector comprises a core and a first dielectric mirror formed over at least a portion of the core to reflect light having a preselected wavelength. The reflector may comprise a plurality of dielectric mirrors formed concentrically over the first dielectric mirror to reflect light having the preselected wavelength. The multiple dielectric mirrors may have different diffraction indices. A layer of such reflectors deposited onto the reflective surface of a projection screen may enhance the reflective selectivity of the screen to the preselected wavelength. Reflectors formed to reflect different wavelengths may be deposited onto the reflective surface to enhance selectivity to the different wavelengths and minimize reflection of ambient light.

  • Patent number: 7213926
    Abstract: 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.

  • Patent number: 6904389
    Abstract: A product under test is tested remotely. A network accessible site receives input for the product under test from a remote user connected to a network accessible site. The input for the product under test is forwarded to a process that presents the input to the product under test as if the input came from an input device directly connected to the product under test. Display information from the product under test is intercepted. The display information describes a current display generated by the product under test. The intercepted display information is displayed on the network accessible site.

  • Patent number: 6847350
    Abstract: An electronic device has a case and a screen attached to the case. The screen indicates a cursor position. The electronic device further has an input device mounted to the case. The input device includes a curved surface for detecting an object disposed on the curved surface using a light path that transfers an image of the object to an optical sensor. The optical sensor detects the movement of the object across the curved surface and in response, the input device manipulates the cursor position.
