    摘要: Bands of predetectors (92) detect the approach of lines of glyphs (12, 14) within an image being scanned. Linear lines or arrays of glyph detectors (116, 118, 120) are sampled in accordance with the detected approach of lines of glyphs. Each detector array includes a plurality of analog glyph detectors (20, 50) which respond to the presence of glyphs with a characteristic analog output. Preferably, the glyph detectors generate a corresponding analog output of a first polarity or other characteristic in response to glyphs of a first orientation and an output of a second polarity or characteristic in response to glyphs of a second orientation. The analog signals which are characteristic of the detection of a glyph are converted into binary 1's and 0's in accordance with the polarity or other characteristic of the signals. In this manner, glyphs are detected by analog detectors and the information encoded in the glyphs is directly output as a binary signal without computer analysis of the image.

    摘要: The present invention consists of an electroluminescent structure and method of fabrication of that structure in materials which have an indirect bandgap in their bulk form. The processing steps can all be standard VLSI methods. Quantum columns, quantum wires or quantum dots may be formed, for example in an array, by masking, reactive ion etching and oxidation. When the semiconductor core is sufficiently thin, quantum mechanical confinement effects raise the energy and the radiative recombination efficiency of injected carriers. Tuning the core diameters allows selection of individual or multiple wavelength emission bands.

    摘要: A sensor array includes includes multiple sensor elements that each have a collection electrode in contact with a photosensitive layer. The photosensitive layer is configured to produce a detectable response at the collection electrode upon incidence of radiation in a responsive zone of the photosensitive layer. A gate electrode layer is separated from the photosensitive layer by a dielectric layer, with adjustments to voltage applied to the gate electrode layer inducing changes in areal extent of the responsive zone of the photosensitive layer. Changing the size of the responsive zone permits performance of image convolutions for edge detection, data compression, or other Gaussian convolutions by the sensor array, rather than by post-detection electronics.

    摘要: An electrographic printing system comprises oppositely opposed print and complement electrode means to produce a dielectric breakdown through a recording medium transported in a printing gap between the electrode means. A visible mark or image is formed on the surface of the recording medium by (1) forming an aperture in a portion of the recording medium or through the recording medium, (2) ablating or eroding a minute portion of solid conductive pigment medium exposed through the formed aperture, (3) inducing the formation of a pigment aerosol from the explosive effect created during pigment ablation, (4) expulsion of the pigment aerosol through the formed aperture, and (5) confinement of the pigment aerosol to the lip of the formed aperture. The aerosol deposits in the form of a torus on the aperture lip and bonds to the surface of the recording medium. Aerosol containment is created by the employment of a dielectric collar surrounding the print electrode means and the provision of a dielectric overlayer on the surface of the recording medium.
