Latest Patents

One of his latest patents is titled "Hierarchical genome assembly method using single long insert library." This invention is directed towards a hierarchical genome assembly process that produces high-quality de novo genome assemblies. The method utilizes a single, long-insert, shotgun DNA library in conjunction with Single Molecule, Real-Time (SMRT®) DNA sequencing. It eliminates the need for additional sample preparation and sequencing data sets required for previously described hybrid assembly strategies. The efficient de novo assembly from genomic DNA to a finished genome sequence is demonstrated for several microorganisms using as little as three SMRT® cells. Additionally, it is effective for bacterial artificial chromosomes (BACs) using sequencing data from just one SMRT® Cell. A new consensus algorithm is part of this assembly workflow, which takes advantage of SMRT® sequencing primary quality values to produce a highly accurate de novo genome sequence, exceeding 99.999% (QV 50) accuracy.

Another significant patent is for a "High memory capacity DRAM SIMM." This invention involves a dynamic random access memory (DRAM) single in-line memory module (SIMM) that achieves high speed and high storage capacity through optimized physical dimensions. The DRAM SIMM features a printed circuit board with a multi-contact connector, multiple DRAM sets, and a plurality of buffers. The design allows for various standard DRAM chips to be used on the SIMM, achieving different performance and storage capacities while maintaining plug compatibility with a memory board.
