  • Publication number: 20030063386
    Abstract: The invention is a hand-held eye viewing device adapted to be readily positioned in an operative radial displacement, angular orientation and axial standoff position relative to an eye. The eye viewing device includes an eye cup extending from a patient end of the device having a patient end adapted to be received at a patient's eye orbit. An outer diameter of a patient end of the eye cup is sized to correspond to a patient eye orbit such that a viewing axis is substantially centered on patient's pupil when the eye cup is received at an eye orbit. The eye cup is preferably made deformable so that patient comfort is improved and further so that contact of the eye cup with an eye orbit alerts a physician that the device is approaching an operative axial standoff position.

  • Patent number: 6538760
    Abstract: A conversion program selectively decomposes viewable files, such as PDF files, and generates a print-structured, bi-directional stream composed of print data objects, resource objects and command objects. The conversion program uses a mapping table to determine which resources have already been sent to the printer so that redundant resources are not re-sent to the printer. The resources and page data for each page are assembled in order and sent to the printer so that the resources necessary to render a page precede the page data. In this manner the printer always has the resources necessary to print each page. The print data, resource and command objects are sent from a print server which controls the print system to a printer by means of a containerized data stream which is bi-directional. A reply object is used to provide information concerning processing of the data from the print server to the printer.

  • Publication number: 20030011043
    Abstract: A semiconductor device has a thin-film transistor (26) and a MIM capacitor having a capacitor dielectric layer (18) and a dielectric oxidation barrier layer (16) over an electrode comprising copper (14). In one embodiment, the dielectric oxidation barrier layer (16) is a nitride, such as silicon nitride, and the capacitor dielectric layer (18) is a metal oxide, such as tantalum oxide. The dielectric oxidation barrier layer (16) is thin as compared to the capacitor dielectric layer (18). The presence of the dielectric oxidation barrier layer (16) prevents the oxidation of the underlying electrode comprising copper (14) during deposition of the metal oxide. The copper oxidation can form a poor interface between the electrode and metal oxide, leading to adhesion problems and high leakage. Thus, the MIM capacitor of the present invention has good adhesion between the electrode and the insulator and low leakage, rendering the device useful for RF applications.
