  • Publication number: 20040160887
    Abstract: High-capacity pick-up mechanisms operable for selectively reading data from and/or writing data to one or more surfaces of one or more optical storage media are disclosed. These mechanisms comprise a first pivotable structure, a second pivotable structure, a first reflective element, a second reflective element, a light source, and a light receiving device. The light source and the light receiving device are remotely located from the reflective elements via the pivotable structures, and only the reflective elements and a portion of the pivotable structure are positioned adjacent the surface of an optical storage medium. High-capacity optical read/write devices and systems comprising these high-capacity pick-up mechanisms are also disclosed.

  • Publication number: 20040007970
    Abstract: Organic light emitting devices are disclosed that use a micro electromechanical system (MEMS) structure to enable a pixel and pixel array wherein each pixel contains a MEMS and an OLED element. A MEMS structure is used for switching the OLED element. These OLED/MEMS pixels can be fabricated on flex circuit, silicon, as well as other inorganic materials. They can be fabricated in a large array for developing a 2-dimensional display application and each pixel can be addressed through conventional matrix scanning addressing scheme. The ability of fabricating these OLED/MEMS pixels on flexible organic substrates as well as other rigid substrates enables wider selection of substrate materials for use with different applications.

  • Patent number: 6643592
    Abstract: A method and system for accessing a remote site by a field engineer faced with a machine fault. The remote site includes various expert systems and fault prediction tools to assist the field engineer. In the event the field engineer is unable to diagnose the fault and repair the machine the machine is returned to a repair center, accompanied by an automatically generated return code that identifies the various analysis conducted by the field engineer and the potential fault causes identified during that analysis process.

  • Patent number: 6259831
    Abstract: A switch element utilizes a single polarizer to couple two discreet inputs to any combination of two discreet outputs along non-blocking optical paths. This switch element may be conveniently networked to additional switch elements for scaling to switches having larger numbers (N) of inputs and outputs. The present invention provides advantages typically associated with conventional polarization gates, including terabit per-second data rates, to facilitate use in fiber-optics networks. This switch element is relatively robust and insensitive to environmental disturbances and has a reconfiguration time which is an order of magnitude faster than conventional optomechanical switches which generally require tens of milliseconds before reconfiguration. The switch element provides constant data pathlength for constant latency, loss, and unskewed data output.

  • Patent number: 6215516
    Abstract: A method and apparatus for converting a monoscopic image with one perspective to a stereoscopic image with two perspectives is provided. A foreground object is identified and outlined. The depth of the object is endowed with depth information. The second perspective is generated by image warping. Alternate embodiments comprising additional features, such as removing redundant frames, which reduce the necessary computation are also provided.
