  • Patent number: 7298084
    Abstract: Methods and displays utilize row and column drivers with ZnO channels that control pixel transistors with ZnO channels, which in turn address OLEDs of an array to produce images of a display screen. A display backplane including the ZnO row and column drivers and the OLEDs may be constructed by utilizing aperture masking or a combination of photolithography and aperture masking. Monolithic integration of the ZnO row and column drivers together with the ZnO pixel transistors is thereby achieved.

  • Patent number: 7256012
    Abstract: A method of biological assay comprises the steps of providing an enzyme substrate comprising two fluorescence dye groups bound to a flexible peptide, the dye groups being of proximity sufficiently close so as to allow free energy attractions to draw the dyes together to essentially self-quench fluorescence of the dye groups, wherein self quenching of fluorescence of the dye groups is effected by dye dimerization or stacking, and enzymatically cleaving the peptide to release the fluorescence dye groups from dye dimerization or stacking, thereby producing an increase in fluorescence intensity. A protease substrate for use in the method of the invention is also disclosed. This invention finds use in detection and identification of microorganisms, sterilization assurance, pharmaceutical discovery, enzyme assays, immunoassays, and other biological assays.

  • Patent number: 7167106
    Abstract: Methods and systems use a programmable sign display located in proximity to a traffic light to provide information to motorists upon the motorists directing their attention toward the traffic light. The programmable sign display may receive programming for content to be displayed in various ways, such as through an interface to a telephone network accessible by a cell phone that sends programming information to the sign. The programmable sign may be used to inform motorists of a radio frequency upon which relevant information such as advertising or traffic reports is being broadcast. The programmable sign may be used to provide textual or graphical information, such as an instruction to motorists that relates to avoiding an approaching emergency vehicle. Additionally, management of the sign is provided to coordinate programming and control of the content being displayed.
