Abstract:
A detector element with one or more attached antenna for the detection of high energy transmissions, including microwaves, lasers, electromagnetic signals, RF waves, radiation, and/or other transmissions emitted by a source including a weapon system. The element may also be used as a safety device to warn and alert personnel working around high energy devices of electromagnetic leaks.

A Photoelectric sensing array system with daughter boards daisy chained together so that varying size touch systems can be modularly constructed using the same electronics. The system also provides for increased touch resolution.
Abstract:
Tiled substrates containing hollow gas filled plasma-shells for radiation detecting or sensing. The gas filled plasma-shells are placed on or within the surface of a substrate which may be a printed circuit board. Multiple substrates containing plasma-shells are tiled together edge to edge to form a self-supporting structure such as a dome or hemisphere for radiation detection.
Abstract:
An AC or DC microdischarge device that comprises a fluorescent conversion material (FCM) and a multiplicity of gas filled microcavity cells, each cell being connected to two or more electrodes to cause a gas discharge in the cell, the gas discharge providing photons that excite the FCM such that the FCM emits IR. In one embodiment, the electronic circuitry for each cell comprises at least one integrated active component such as a transistor. Other active components may be included such as a high speed shift register, addressing logic, and/or control circuits. In another embodiment, the microcavity and active components are made from the same substrate such as the same silicon wafer. The microdischarge device may include one or more electrodes encapsulated in a dielectric. The electrodes are configured to ignite a microdischarge in a microcavity cell when an AC or a pulsed DC excitation potential is applied between the electrodes connected to the cell. The devices include linear and planar arrays of microdischarge devices. The microcavities in the planar arrays may be selectively excited for display applications.
Abstract:
A single substrate AC and/or DC gas discharge (plasma) display device with hollow shells containing ionizable gas at a predetermined pressure, each shell being positioned on the surface of the substrate or within a substrate cavity, well, or hollow. Each shell is in electrical contact with at least one electrode, typically two, three, or more electrodes. The AC or DC gas discharge within each shell emits photons in the visible and/or invisible range. In one embodiment, photons from the gas discharge within a shell excite a luminescent substance or material such as a phosphor that emits photons in the visible and/or invisible spectrum. The shell may contain the luminescent substance or the substance may be located separately from, but in close proximity to the shell.
Abstract:
A chroma-key/matte display screen system with a touch input device that allows a user to interact with the display by selecting or pointing to composite images on the display. Touch input devices include camera based, infrared, membrane, and acoustic. Displays screens include CRT, various flat screen displays such as plasma, LCD, OLED, and various projection display systems.
Abstract:
Visual artifact reduction method for a display comprising the use of gamma correction. Other artifact reduction methods can be used with gamma corrections including error diffusion, dithering, and center of light.
Abstract:
An active matrix organic LED display having a matrix of multiple light emitting pixels and electronic drive circuitry for selectively addressing the pixels, each pixel containing an organic LED. The electronic drive circuitry includes row scan electrodes and column data electrodes that interconnect the matrix of pixels. The circuitry also includes a MEMS switching device and a memory capacitor for each pixel, the MEMS switching device connecting the memory capacitor to a column data electrode during addressing of a pixel and connecting the memory capacitor to the organic LED of each pixel during light emission.
