Abstract: An infrared imager includes an array of capacitance sensors that operate at room temperature. Each infrared capacitance sensor includes a deflectable first plate which expands due to absorbed thermal radiation relative to a non-deflectable second plate. In one embodiment each infrared capacitance sensor is composed of a bi-material strip which changes the position of one plate of a sensing capacitor in response to temperature changes due to absorbed incident thermal radiation. The bi-material strip is composed of two materials with a large difference in thermal expansion coefficients.

Abstract: 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, and 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.

Abstract: LED pixel structures and methods that improve brightness uniformity by reducing current nonuniformities in a light-emitting diode of the pixel structures are disclosed.

Abstract: A display structure is formed using patterned deposition of display materials. A substrate includes a plurality of distinct electrodes. A plurality of droplets including a material are formed and charged to a second polarity. First selected ones of the plurality of electrodes are charged to a first polarity opposite the second polarity to selectively attract the droplets including the material to the oppositely charged first selected ones of the plurality of electrodes.

Abstract: An ion source including an electron generating chamber and an ionization chamber adjacent the electron generating chamber and having an opening therebetween. The ionization chamber has a gas inlet opening and the electron generating chamber has a outlet. The gas inlet opening, the outlet and the opening between the two chambers are all on a common axis. The electron generating chamber has therein a cathode filament which extends completely around the axis and generates electrons, electrodes for directing the electrons transversely toward the axis and a deflection electrode for deflecting the electron flow along the axis and into the ionization chamber. An accelerator plate is adjacent the outlet and is adapted to attract ions generated in the ionization chamber along the axis and through the outlet.
