摘要： A pipeline A/D converter and its single redundancy bit digital correction are provided. The single redundancy bit digital correction includes the following steps: substages except for the last one quantizes input voltage, calculates the residual voltage, which is amplified and shifted to the middle part of the reference voltage range, and outputs to the following substage until the last one, which only quantizes the input voltage; the code and offset code of each substage corresponding to the quantized thermometer code are calculated; the offset codes of all stages are added by weight to get total offset code; and codes of all substages are added by weight, to which the total offset code is added. The comparator offset error is corrected to obtain an output code which identifies the negative or positive overflow of input signals. The A/D converter adopting the above digital correction is provided.

摘要： An imaging technology for fuel cells is based on x-ray microscopy. A metrology system images the electrochemical interaction areas of solid-oxide fuel cells (SOFC) in-situ. This system takes advantage of both the penetrating power and elemental absorption contrast of hard x-ray radiation to image the internal interaction areas in a SOFC. The technology can further take advantage of the strong dependence of the x-ray absorption on material type and energy to distinguish the four major material types: cathode, electrolyte, air, and low-Z contaminants such as sulfur.

摘要： Methods for fabricating refractive element(s) and aligning the elements in a compound optic, typically to a zone plate element. The techniques are used for fabricating micro refractive, such as Fresnel, optics and compound optics including two or more optical elements for short wavelength radiation. One application is the fabrication of the Achromatic Fresnel Optic (AFO). Techniques for fabricating the refractive element generally include: 1) ultra-high precision mechanical machining, e.g,. diamond turning; 2) lithographic techniques including gray-scale lithography and multi-step lithographic processes; 3) high-energy beam machining, such as electron-beam, focused ion beam, laser, and plasma-beam machining; and 4) photo-induced chemical etching techniques. Also addressed are methods of aligning the two optical elements during fabrication and methods of maintaining the alignment during subsequent operation.

摘要： A scintillated CCD detector system for imaging x rays uses x-rays having a photon energy in the range of 1 to 20 keV. The detector differs from existing systems in that it provides extremely high resolution of better than a micrometer, and high detection quantum efficiency of up to 95%. The design of this detector also allows it to function as an energy filter to remove high-energy x-rays. This detector is useful in a wide range of applications including x-ray imaging, spectroscopy, and diffraction. The scintillator optical system has scintillator material with a lens system for collecting the light that is generated in the scintillator material. A substrate is used for spacing the scintillator material from the lens system.

摘要： A lithography apparatus having achromatic Fresnel objective (AFO) that combines a Fresnel zone plate and a refractive Fresnel lens. The zone plate provides high resolution for imaging and focusing, while the refractive lens takes advantage of the refraction index change properties of appropriate elements near absorption edges to recombine the electromagnetic radiation of different energies dispersed by the zone plate. This compound lens effectively solves the high chromatic aberration problem of zone plates. The lithography apparatus allows the use of short wavelength radiation in the 1-15 nm spectral range to print high resolution features as small as 20 nm.

摘要： An optical reader apparatus is configured to detect epidermal ridges of a body part using specular reflection contrast detection. The optical reader apparatus comprises a display comprising a transparent cover and a substrate comprising an array of active pixels. The active pixels serve as an illuminator of the optical reader apparatus. The apparatus also comprises a pinhole array and an optical sensor optically coupled to the display via the pinhole array. The optical sensor comprises an array of photosensors arranged on a substrate. The array of photosensors is configured to detect light reflected via specular reflection by the transparent cover. A processor, coupled to the display and the optical sensor, is configured to control reading of signals from the photosensors and to control illumination of selected active pixels in accordance with a predefined scanning pattern that covers a sensing region of the transparent cover during a body part reading operation.
