| 20090081735 | NOVEL PROCESS - Novel organisms, including DNA construct host cell combinations, are disclosed. The organisms comprise a transcription unit (e.g. operon) comprising DNA sequences encoding for enzymes which promote the supply of single carbon units for the conversion of dUMP to dTMP. Examples include: dihydrofolate reductase genes e.g. T4 frd; Serine Hydroxymethyltransferase genes e.g. glyA; 3-phosphoglycerate dehydrogenase genes e.g. serA; and THF synthase genes e.g. ADE3. The organisms are used in a biological method of producing thymidine with significantly reduced levels of uridine. | 03-26-2009 |

| 20090314510 | Elastomeric Conductors and Shields - Systems and methods presented herein provide for elastic conductors. The elastic conductors may be configured with a primary that includes an elastic material and a conductive material. For example, the primary may have an elastic fiber, such as spandex, with a conductive material, such as a braided metal wire, wrapped thereabout. Alternatively, the primary may be configured from an elastic material with a conductive material, such as certain nanopartiuclates, embedded therein. The elastic conductors may be used in a variety of ways to form various types of cables. For example, the elastic conductors may be configured to form coaxial cables, USB cables, twisted pairs, etc. The elastic and flexible nature of the cables may make their uses advantageous in wiring environments that are subjected to strain or other harsh conditions. Moreover, the relatively light weight of the cables may make their uses more advantageous in transportation (e.g., aircraft, automobiles, etc.). | 12-24-2009 |

| 20090139232 | Ambient Temperature Energy Generating System - A system for generating energy which utilizes motive chemicals | 06-04-2009 |
| 20090149337 | Use of an Extraction Control in a Method of Extracting Nucleic Acids - The present invention relates to a method of ensuring the effectiveness of the extraction workup from a biological sample of nucleic acid. The inventive method is able to distinguish between possible defects in the extraction of nucleic acid from a sample and possible defects in a subsequent amplification step. The present invention also relates to a packaged array for extracting nucleic acid from a biological sample. | 06-11-2009 |
| 20090155808 | Automated system for isolating, amplifying and detecting a target nucleic acid sequence - A system and method for preparing and testing of targeted nucleic acids is presented. The system integrates a pipetter, extractor, assay reader, and other components, including a selectively compliant articulated robot arm (SCARA). This synergistic integration of previously separate diagnostic tools creates a system and method whereby a minimum of human intervention is required. The resulting system provides a substantially more accurate and precise method of isolating, amplifying and detecting targeted nucleic acids for diagnosing diseases. | 06-18-2009 |
| 20100286380 | PRETREATMENT METHOD FOR EXTRACTION OF NUCLEIC ACID FROM BIOLOGICAL SAMPLES AND KITS THEREFOR - The present invention relates to methods for pretreating biological samples for extraction of nucleic acid therefrom. The present invention employs a combination of at least one protein denaturant with one or more of the following elements to form a reaction mixture for extraction of nucleic acid: (1) at least one aprotic solvent, (2) stepwise heating, and (3) sample dilution. | 11-11-2010 |

| 20100236785 | METHOD FOR REMOVING HYDRATE PLUG FROM A FLOWLINE - A method of drilling through a blockage in a flowline using a remotely controlled electrically operated drilling tool that comprises a drill bit, a steering means, a pumping means, and a propulsion system wherein the drilling tool is connected either directly or indirectly to an electric cable and the drill bit is mounted on the steering means, the method comprising: introducing the drilling tool into the flowline; actuating the electrically operated propulsion system to move the drilling tool through the flowline to the location of the blockage; actuating the electrically operated steering means so that the drill bit is aligned with the blockage; actuating the electrically operated drill bit so that the drill bit engages with and drills through the blockage; and actuating the electrically operated pump so that when the drill bit engages with the blockage, fluid that is present in the flowline adjacent the blockage is passed over the cutting surfaces of the drill bit and cuttings from the blockage are transported away from the cutting surfaces of the drill bit suspended in the fluid. | 09-23-2010 |
