Abstract:
A fiber-based display includes orthogonal arrays of fiber with co-drawn wire electrodes placed between two plates to form an information display. One of the key concepts of the invention is that all structure of each row and column of a display panel is contained within each fiber of both arrays. Therefore, the entire functionality of the display is contained within each fiber of the display. Containing the structure of the display within the fibers not only eliminates multi-level alignment process steps, but allows for the fabrication of very large flat panel displays. The fiber arrays (17 or 27) are formed by drawing fiber from a preform onto a cylindrical drum (70) and then removing them from the drum as a sheet of fibers. The fiber arrays are assembled between the plates before a seal is applied. Tight control of the fiber shape and cross-section is obtained using a lost glass or polymer process. The cross-sectional shape of the fibers in the fiber arrays are suitable for use in a flat panel display, such as plasma emissive displays, plasma addressed liquid crystal displays, field emission displays, three-dimensional and multiple view displays.
Abstract:
The object of the invention is to provide a plasma addressed display device which can adapt the amount of dopant gas released or absorbed by the storage material to a changing real-operating/environment conditions of the display device in order to control the partial pressure of the dopant gas in the channel. Configuration: A plasma addressed display device comprising: a channel substrate (2) provided with an array of interconnected longitudinal channel chambers; a cover sheet (4) extending over the channel chambers (30) and making seals to the channel chambers on a side of an upper face of the chamber, whereby the channel substrate and the cover sheet define sealed channel chambers; a pair of electrodes (3a,3c) located in each sealed channel chamber for selectively ionizing a gas within the channel chamber; a dopant source (53) having a storage material that reversibly absorbs and releases a dopant gas to be mixed with a primary ionizable gas in the sealed channel chambers; and a heater (5H) for heating the storage material. The device is provided with a feedback loop (100-103, 5H) for a control of partial pressure of the dopant gas within the sealed channel chambers, the feedback loop comprising: measurement means (100,101) for measuring a value of a decay time of an electrical conductivity in at least one of the channel chambers from turning off the plasma in the channel chamber; and control means (102, 103) for controlling a temperature of the storage material through the heater (5H) on the basis of the measured value so that the decay time is within a predetermined range.

Abstract:
A hollow grain propellant (10) for use in a lightweight training round. The hollow grain propellant (10) incorporates multi-perforation propellant grain geometry. The hollow grain propellant (10) is configured as a propellant grain having a center hole (20) surrounded by uniform perforations (30). The center hole (20) is larger than any one of the uniform perforations (30). The placement of the uniform perforations (30) forms webs (34, 36, 38) of equal length. The hollow grain propellant (10) may include seven or more perforations (30). The perforations (30) are arranged in a single ring around the center hole (20). The size of the center hole (20) may be controlled to produce a wide range of bulk densities. The number of perforations (30) may be dependant on the size of the center hole (20). The number of perforations (30) may be controlled to vary with the size of the center hole (20) to provide for a desired bulk density. The large center hole (20) improves flame permeability through a propellant bed by increasing the porosity of the propellant bed and increasing grain diameter (12). The hollow grain geometry maintains good progressive burning characteristics at low bulk densities while retaining low mass fraction at slivering. The hollow grain propellant (10) further eliminates the need to reduce ullage with costly spacers, fillers, or liners.
