A microfluidic device has a layer that has a capillary break formed by a capillary sluice. The capillary sluice has a lower surface and an upper surface. An input channel is coupled to the capillary break. A first electrode is disposed proximate the lower surface. The first electrode is coupled to the voltage source. A second electrode is spaced a first predetermined distance from the first electrode coupled to the voltage source. A third electrode is spaced apart from the second electrode and positioned within the input channel from the first electrode coupled to the voltage source.

Method of moving fluid in a microfluidic device

A method for accomplishing a plurality of combinatorial processes in parallel using a microelectronic and fluidic array (device array) having micron-sized reservoirs, connecting microchannels and reaction cells etched into a substrate. The device array has a top feedthru plate, a center distribution plate and a bottom cell plate. The top feedthru plate serves as a cover for the device array and contains apertures selectively positioned above the reservoirs located in the center distribution plate. The center distribution plate includes a plurality of micron sized reservoirs, microchannels, reservoir feeds, cell feeds and overflow feeds for the distribution of reagent fluids to the reaction cells located in the bottom cell plate. The detachable bottom cell plate serves as a microlaboratory tray of reaction cells. Once the proper reagents or other materials are introduced into the reaction cells, the bottom cell plate is decoupled from the device array and removed for incubation or analysis.

Apparatus for separating molecules

A display as for images and/or information comprises a plurality of light-emitting fibers disposed in side-by-side arrangement to define a viewing surface. Each light-emitting fiber includes a plurality of light-emitting elements disposed along its length, each having two electrodes between which are applied electrical signals to cause the light-emitting element to emit light to display a pixel or sub-pixel of the image and/or information. The light-emitting fiber includes an electrical conductor disposed along its length to serve as a first electrode, a layer of light-emissive material disposed thereon, and a plurality of electrical contacts disposed on the light-emissive material to serve as the second electrodes of the light-emitting elements. Preferably, the conductors, light-emissive layer and plurality of electrical contacts are formed in a continuous process wherein a transparent fiber passes through a plurality of processing chambers for receiving the electrical conductor, the light-emissive layer and the plurality of electrical contacts thereon.

Fiber-based flat panel display

A display as for images and/or information comprises a plurality of linearly addressed light-emitting fibers disposed in side-by-side arrangement to define a viewing surface. Each light-emitting fiber includes a plurality of light-emitting elements disposed along its length which is linearly addressed by signals provided by a drive circuit at one end thereof. Linear addressing signals are either optical signals or electrical signals, and may be frequency modulated, digitally encoded or analog encoded. A detector associated with each pixel detects the linear addressing signal and decodes same to activate and deactivate organic or inorganic light-emitting material elements. Thus, the light-emitting elements emit light to display a pixel or sub-pixel of the image and/or information. The light-emitting fiber may include a transparent fiber as substrate for propagating the optical signals therethrough and may include electrical conductors disposed along its length for propagating the electrical signals.

An electroluminescent display formed on a ceramic substrate having a front ceramic surface and a back ceramic surface. The ceramic substrate includes a metal core that provides structural support, electrical ground, and heat dissipation. Electroluminescent cells are mounted on the front ceramic surface and driver circuits for driving the of electroluminescent cells are mounted on the back ceramic surface. The driver circuits are positioned directly behind said electroluminescent cells. Connectors extend through said ceramic substrate and the electroluminescent cells to different driver circuits. By positioning the driver circuits close to the EL cells, the drive lines from the drivers to the EL cells are short which allows for high refresh rates and low resistance losses. Each of the driver circuits can drive one electroluminescent cell or a group of electroluminescent cells. EL display cells coupled to a cermet electrode can also be driven by a field emission device or a low power electron beam.
