Abstract: Communication to or from a nanodevice is provided with a nanostructure-based antenna, preferably formed from, but not limited to, a single wall nanotube (SWNT). Other nanostructure-based antennas include double walled nanotubes, semiconducting nanowires, metal nanowires and the like. The use of a nanostructure-based antenna eliminates the need to provide a physical communicative connection to the nanodevice, while at the same time allowing communication between the nanodevice and other nanodevices or outside systems, i.e., systems larger than nanoscale such as those formed from semiconductor fabrication processes such as CMOS, GaAs, bipolar processes and the like.

Abstract: The invention provides, in one exemplary embodiment, an isolation gate formed over a substrate for biasing the substrate and providing isolation between adjacent active areas of an integrated circuit structure, for example a DRAM memory cell. An aluminum oxide (Al2O3) is used as a gate dielectric, rather than a conventional gate oxide layer, to create a hole-rich accumulation region under and near the trench isolation region. Another exemplary embodiment of the invention provides an aluminum oxide layer utilized as a liner in a shallow trench isolation (STI) region to increase the effectiveness of the isolation region. The embodiments may also be used together at an isolation region.
Abstract: An active pixel sensor (APS) that includes circuitry to eliminate artifacts in digital images. The APS includes a comparator for comparing a signal level from a pixel to an adjusted saturation voltage to determine if the pixel is saturated. If the pixel is saturated, the signal output from the pixel is replaced with an analog voltage having a maximum value corresponding to a brightest pixel in the image.
Abstract: An integrated semiconductor optical-emitting device includes a surface-emission laser diode and an EA-type semiconductor optical modulator integrated commonly on a GaAs substrate in a direction perpendicular to the GaAs substrate.
Abstract: Systems and methods are provided that facilitate grey level magnification to improve details and contrast for a dark scene of video on a digital display system. Preferably implemented over a limited pixel level range, the video enhancement process counts the number of pixels corresponding to each level within the range in a frame and then, based on the percent level distribution of the pixels, calculates the stack of percentage distribution. From the stack of percentage distribution, a transformation process is performed to reassign the pixel values over a dark level range and to expand the distribution of the pixels. The result of transformation enhances the details and contrast of the dark area significantly without affecting the bright scene. By only applying the algorithm to dark scenes, computation loads are reduced compared with some of the full picture processing methods. Lower computational loads are important to reduce motion artifacts in high speed video applications.

Abstract: A look-up table (LUT) is arranged as a plurality of rows each indexed by an index value and storing at least a coefficient for each index value for use in processing digital data. The LUT contains repeated sections in which m coefficients stored for successive index values form a cycle. The number m is not an integer power of 2. For example the LUT may be used when converting a digital count to a gain in dB, in which case m may be 6 or 12, the coefficients representing dB or fractional-dB steps in gain. The LUT contains n additional blank rows inserted after every repeated section of m rows storing the cycle of m coefficients, n being 1 or more and (m+n) being an integer power of two (such as 8 or 16). By feeding an initial index value through encoding logic which takes account of the additional rows, it can be ensured that these are never indexed. Thus, a sparse-coded LUT is provided.

Abstract: The transporting device according to the invention, in particular for transporting sheet-like substrates through a coating installation, comprises transporting rollers which are rotatably mounted on both sides and horizontally arranged transversely in relation to the transporting direction, the uppermost surface lines of the transporting rollers defining the transporting plane, and is characterized in that the end parts of the transporting rollers have a smaller diameter than the middle part of the transporting rollers and in that baffles which are mounted displaceably in the axial direction of the transporting rollers between a first position and a second position are arranged between the end parts of the transporting rollers and the transporting plane. The fact that the baffles are mounted in an axially displaceable manner has the effect of considerably extending the cleaning intervals of the transporting device.

Abstract: An anonymous trading system includes a prime broker facility that allows a third party to trade on behalf of an institution. A deal is executed between the third party and a counter-party and a further deal is then executed between the third party and the party on whose behalf it has traded. The second deal may be for the same amount as the first deal or may be altered to include the third party's fee for conducting the first deal. Clients of the third party have prices available to them for trades made via the third party which are displayed at their trader terminals. The client sees that a better price is available though the third party than by dealing direct and selects to conduct a deal through the third party.
