In addition, a broadband laser source will also unfold many news products in communications and medi...Fri, 20 Feb 2009 10:39:20 GMTjwr304@lehigh.edu Indicators - Demand Characterization for Short Life-Cycle Technology Products (Technology #:091406-01), 20 Feb 2009 10:39:19 GMTjwr304@lehigh.edu Dummy-gate (field-plate) Bias Technique for RF LDMOSFETs (Technology#: 090506-01) invention uncovers a method of applying a suitable modulated bias to the dummy-gate (or field-plate) in RF-LDMOSFETs to improve the efficiency and output power. Initial tests of this technique show a 60% improvement in the maximum output power, and a 10% improvement in the efficiency of the device. The increase in output power will translate to a greater coverage area for cellular base stations that use this transistor, and the improved efficiency will reduce the heat dissipation and related reliability problems. These improvements will lead to a clearer and stronger signal on the ...Fri, 20 Feb 2009 10:39:19 GMTjwr304@lehigh.edu Spectroscopy Platform for DNA Sequencing (Technology #: 083106-02) Spectroscopy for Genomics delivers fast and affordable genome sequencing through detection of a single nucleotide addition (SNA) by analysis of changes in mechanical properties and molecular structure of single DNA fragments. It provides a massively parallel format for genome sequencing that does not use amplification, separation, or labeled nucleotides. Force spectroscopy of DNA undergoing arrested polymerization implements a one-molecule-at-a-time analysis to determine changes in molecular elasticity. With the use of optical near field probes, the method of force spectroscopy has...Fri, 20 Feb 2009 10:39:19 GMTjwr304@lehigh.edu of the Wake of a Cylinder: Effect of Small Amplitude Surface Perturbation (Technology #: 040506-01), 20 Feb 2009 10:39:18 GMTjwr304@lehigh.edu Type-II InGaN-(In)GaNAs 'W' Quantum Well Gain Media for Solid State Lighting Applications (Technology #: 030806-01) technology of this invention allows the engineering of gallium nitride-based quantum well gain media resulting in a significantly larger optical gain for blue-green-red wavelength regimes, in comparison to that of conventional technology. The technology now provides one with the ability to realize gallium nitride-based high efficiency blue-green-red gain media on GaN or sapphire substrate, which can be integrated into a single chip for achieving a high-performance and low-cost solid state lighting for general illumination light sources. The proposed technology in this invention can ...Fri, 20 Feb 2009 10:39:18 GMTjwr304@lehigh.edu
