Abstract: A precoded orthogonal frequency division multiplexer (OFDM) system that improves the preformance of OFDM systems for spectral null channels, and size K×1 vector OFDM systems that reduce the cyclic prefix length by K times compared to conventional OFDM systems. The precoding scheme comprises inserting one or more zeros between each of the two sets of K consecutive information symbols, although it can be generalized to a general form. This precoding scheme removes the spectral nulls of an ISI channel without knowing the ISI channel. When no zero is inserts between each of the two sets of K consecutive information symbols and only K consecutive symbols are blocked together, vector OFDM systems are obtained. The bit error rate performance of the vector OFDM systems of the present invention is much improved over conventional OFDM systems.

The photonic crystal consists of two primary components: (1) a waveguiding element created by line defects formed in the photonic crystal, and (2) frequency-selective elements created by high Q-value microcavities formed in the crystal. The multi-channel WDM system offers a flexible design and high channel density.

Abstract: Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing. compliant, and flexible multi-touch surface. The surface consists of compressible cushion, dielectric, electrode, and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize signal-to-noise ratio and to reduce wiring complexity. Such distributed transduction circuitry is economical for large surfaces when implemented with thin-film transistor techniques. Scanning and signal offset removal on an electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contact and extracts shape, position and surface proximity features for each group.

The system comprises an ion source chamber having a gas inlet and outlet, and a high-energy, pulsed, ultraviolet laser for ablating the single particles in the high velocity gas flow entering the ion source chamber through the gas inlet to produce positively- and negatively-charged ions. The system further includes a first extraction plate for extracting the positively-charged ions provided in the ion source chamber, and a second extraction plate for extracting the negatively-charged ions provided in the ion source chamber. The positively-charged ions are injected into a first ion mobility spectrometer where they are detected and characterized.

Abstract: Disclosed are two novel techniques for digital color halftoning with green-noise stochastic dither patterns generated by homogeneously distributing minority pixel clusters. The first technique employs error diffusion with output-dependent feedback such that the overlapping of pixels of different colors can be regulated for increased color control. The second technique uses a green-noise mask which is a dither array designed to create green-noise halftone patterns. The green-noise mask is constructed to also regulate the overlapping of different colored pixels. As is the case with monochrome image halftoning, both techniques are tunable, allowing for large clusters in printers with high dot-gain characteristics, and small clusters in printers with low dot-gain characteristics.

Abstract: A novel supported mesoporous carbon ultrafiltration membrane and process for producing the same. The membranes comprise a mesoporous carbon layer that exists both within and external to the porous support. A liquid polymer precursor composition comprising both carbonizing and noncarbonizing templating polymers is deposited on the porous metal support. The coated support is then heated in an inert-gas atmosphere to pyrolyze the polymeric precursor and form a mesoporous carbon layer on and within the support. The pore-size of the membranes is dependent on the molecular weight of the noncarbonizing templating polymer precursor. The mesoporous carbon layer is stable and can withstand high temperatures and exposure to organic chemicals. Additionally, the porous metal support provides excellent strength properties. The composite structure of the membrane provides novel structural properties and allows for increased operating pressures allowing for greater membrane flow rates.

Abstract: A method for making a metal-insulator-semiconductor field effect transistor (MISFET) having an oxidized aluminum nitride gate insulator formed on a silicon or gallium nitride substrate. The method of making the MISFET comprises the steps of depositing an aluminum nitride layer on the entire upper surface of the silicon or gallium nitride substrate. Subsequently, the aluminum nitride layer is oxidized to convert it into an oxidized aluminum nitride layer which acts as a gate insulator of the MISFET. Portions of the oxidized aluminum nitride layer are etched to form a plurality of openings that expose regions to become the source and drain regions of the substrate. The source and drain regions are formed in the plurality of openings by conventional techniques including diffusion and ion-implantation. Finally, a metal layer is formed in the plurality of openings of the oxidized aluminum nitride layer, wherein the metal layer contacts the source and drain regions of the substrate.

Abstract: An improved metal-semiconductor-metal (MSM) photodiode, specifically a new high responsivity AND high bandwidth photodetector, resulting in a high gain-bandwidth product is disclosed. The disclosed device is an MSM photodiode in which the anode and cathode are made of different materials of differing opacity and possibly including different electrode dimensions as well. Using an opaque anode and a transparent cathode reduces surface reflections off the opaque electrodes allowing more light to be absorbed within the active semiconductor region. However, it concurrently keeps the transit distance for the slower moving holes to a minimum. Thus, the long tail in the impulse response due to hole collection is minimized, resulting in increased bandwidth.
