A method for pixel to pixel displaying an input video on a spliced display screen is provided. In the spliced display screen, actual physical pixels of a display area of each display screen are distributed on the basis of a physical outer diameter of the display screen according to an nK video standard. The physical outer diameter includes a screen margin/bezel and a display area of a display screen. The physical pixels of the nK video standard are uniformly distributed in the whole physical outer diameter of the display screen with a bezel, including being uniformly distributed in the width of the margin/bezel. The actual physical pixels in the display area of the display screen are fewer than those of the nK video standard, and the width occupied by the missing pixels is consistent with that occupied by the display screen margin/bezel. The method provides the probability of directly playing the nK input video and overcomes the limit that the input video respectively sent to each spliced display screen can be played only after being amplified.

The search for rare-events, such as double beta decay or dark matter detections, is primarily a fight to reduce the incidence of background events to sufficiently low levels so that the events of interest can be seen. Two major sources of background are trace amounts of radio-impurities found within the materials used to construct, support, and shield these experiments, and the contamination of these materials surfaces caused by exposure to atmospheric radon. Direct detection of alpha emission is necessary to accurately determine the levels of surface contamination on these ultra-pure materials, but currently available screening techniques do not have sufficient sensitivity to characterize these materials at the levels required. The DOE, which is a major supporter of rare-event search activities, therefore has an active interest in the development of ultra low activity materials. By extension, there is also an active interest in developing instrumentation for characterizing such ultra low activity materials, since it is impossible to improve something that cannot be measured. Approach: In this project we are proposing to develop an instrument to effectively characterize radiopure materials for surface alpha emission, an instrument whose lower detection limit will be over 100 times lower than that of the best commercially available instruments. XIA manufactures and sells the UltraLo-1800 alpha particle counter, which represents the current state-of-the-art in low background alpha particle detection. In the proposed approach, we will convert the UltraLo-1800 from an ionization chamber into a time projection chamber, which will allow us to push achievable background rates towards 1 alpha/day/m2, without shielding at the earth’s surface. This enhanced sensitivity will allow for the relatively rapid characterization of ultra-pure materials without having to conduct the measurement underground. Commercial Application & Benefits: If successful, this instrument’s direct benefit will be its support of a variety of rare-event experiments which seek to expand our understanding of the basic principles upon which the universe operates. Moreover, the enhancements made to the capabilities of the UltraLo-1800 will provide a significant performance advantage in other areas, including environmental remediation measurement of alpha radiation, and the semiconductor packing industry where controlling alpha activity from packaging materials is critical to increasing device reliability. Key Words: Low background, alpha particle detector, time projection chamber

A method for three-primary-color combined gamma calibration is disclosed. Three-primary-color combined gamma calibration is applied to two electro-optic display systems with three primary colors having intrinsic wavelengths which are not completely the same or to a single electro-optic display system. Not only the electro-optic nonlinearity is calibrated but also the output dominant wavelengths of the systems are calibrated. This calibration is achieved by way of actively bringing in and superposing other primary color components, and the superposed components are the functions of the calibrated primary colors in the whole color gamut space. Thus, effective migrations occur to output dominant wavelengths of three primary colors of the systems with respect to intrinsic wavelengths or dominant wavelengths of the original three primary colors, so that output dominant wavelengths of two groups of three primary colors with intrinsic wavelengths which are not completely the same of two systems trend to be consistent in the whole color gamut space, or so that the output dominant wavelengths of a single system meets the calibration requirements in the whole color gamut space.

A technique for characterizing the noise behavior of a superconducting tunnel junction (STJ) detector as a function of its applied bias voltage V_(b )by stepping the STJs bias voltage across a predetermined range and, at each applied bias, making multiple measurements of the detectors current, calculating their mean and their standard deviation from their mean, and using this standard deviation as a measure of the STJ detectors noise at that applied bias. Because the method is readily executed under computer control, it is particularly useful when large numbers of STJ detectors require biasing, as in STJ detector arrays In a preferred implementation, the STJ is measured under computer control by attaching it to a digital spectrometer comprising a digital x-ray processor (DXP) coupled to a preamplifier that can set the STJs bias voltage V_(b )using a digital-to-analog converter (DAC) controlled by the DXP.
