Abstract: Four genetic traits have been identified that increase furfural tolerance in microorganisms, such as ethanol-producing Escherichia coli LY180 (strain W derivative). Increased expression of fucO, ucpA or pntAB, and deletion of yqhD were associated with the increase in furfural tolerance. Microorganisms engineered for resistance to furfural were also more resistant to the mixture of inhibitors in hemicellulose hydrolysates, confirming the importance of furfural as an inhibitory component. The combinations of genetic traits disclosed in this application can be applied, generally, to other microorganisms, such as Gram negative and Gram positive bacterial cells, yeast and fungi to increase furfural tolerance in microorganisms used to make industrially useful products.

The coated surfaces have a first refractive index. A cavity is formed by the first and second layers and a sealant that seals perimeter of the first and second layers. A fluid is filled in the cavity. The fluid has a second refractive index.

Abstract: An apparatus for an improved backlight display is described. The invention includes a dimmable light source which directs light through a filter before the light from a light source is distributed by a light guide.

Abstract: A backlight comprising a serpentine fluorescent tube nested in a uniquely shaped reflector. Much of the light emitted from the tube is directly emitted to a bounded image plane. The reflector reflects a substantial portion of the rest of the light emitted by the tube to the image plane in such a manner that a very bright and uniform image is formed at the image plane.

Abstract: A thin-film electroluminescent display panel system has a plurality of vertical column electrodes driven by column driver circuits and a plurality of horizontal row electrodes driven by row driver circuits. The system includes a row driver control circuit that enables the row drivers in a first sequence during a first display frame so that write voltage pulses are applied to the row electrodes in order from the top to the bottom of the display panel. The row driver control circuit enables the row drivers in a second sequence during a second display frame so that the write voltages are applied to the row electrodes in the reverse order from the bottom of the display panel to the top of the display panel.

Abstract: An AC-powered display system includes a gas discharge display panel, an integrated circuit, and a limiting network. The integrated circuit is provided as the display pattern controller. The limiting network, in response to an excessive voltage across the controller, reduces the current through the system. The reduction in system current causes the voltage across the integrated circuit to be regulated.

Abstract: The disclosure is of a system for driving gas-filled segment-type display panels including a plurality of groups of cathode electrodes, each having an anode electrode. The circuit includes means for holding the anodes at a relatively low potential for a short period of time after drive signals are applied thereto and to selected cathode electrodes. During this period of time, current flow charges a capacitor and raises the potential of the anodes to a potential at which ionization and cathode glow can occur. The circuit includes transistors utilized as resistors to hold off cathodes which are not intended to glow.
