  • Publication number: 20190225952
    Abstract: The present disclosure provides variant Pol6 polymerase polypeptides, compositions comprising the Pol6 variant polypeptides, and methods for using the variant Pol6 polypeptides for determining the sequencing of nucleic acids, for example, by nanopore sequencing. The variant Pol6 polymerases possess decreased rates of dissociation of template from the polymerase-template complex, which result in increased processivity relative to the parental Pol6 polypeptides from which they are derived.

  • Patent number: 8710265
    Abstract: A solvent that reversibly converts from a nonionic liquid mixture to an ionic liquid upon contact with a selected trigger, e.g., contact with CO2, is described. In preferred embodiments, the ionic solvent is readily converted back to the nonionic liquid mixture. The nonionic liquid mixture includes an amidine or guanidine or both, and water, alcohol, or a combination thereof. Single component amine solvents that reversibly convert between ionic and non-ionic states are also described. Some embodiments require increased pressure to convert; others convert at 1 atmosphere.

  • Patent number: 7404943
    Abstract: Methods of enhancing the solubility of a fluorinated compound in an organic solvent are provided. In one embodiment, carbon dioxide gas pressure is applied to the solvent at a pressure effective to enhance the solubility of the fluorinated compound. The method may further include recrystallizing the fluorinated compound by reducing the pressure of the carbon dioxide gas. Also provided are methods of conducting a reaction using a fluorinated compound in an organic solvent. In one embodiment, the method comprises applying carbon dioxide pressure to an organic solvent comprising at least one substrate and a fluorinated catalyst, in an effective amount to solubilize the catalyst; and permitting the fluorinated catalyst to catalyze the reaction of the substrate to form a product. The catalyst is optionally separated from the reaction product and solvent after the reaction by the release of the pressure.

  • Publication number: 20070288165
    Abstract: A method and system for degimbalization of sensor outputs is provided. Data output from an embedded GPS inertial navigation system (EGI), which is mounted within a gimbaled system on a vehicle, is processed to provide degimballed navigation data. Generally, motion of the EGI is due to the vehicle motion and the gimbal motion. To provide navigation information relating solely to the vehicle, effects of the gimbal motion within the EGI outputs can be removed.

  • Patent number: 7293956
    Abstract: An annular air baffle for use in a cavity of an annular rotatable gas turbine engine component includes an annular split baffle ring having a plurality of circumferentially spaced apart and radially inwardly extending intermediate dams circumferentially disposed between first and second end dams. The intermediate dams and the first and second end dams extend radially inwardly from a continuous annular section. Voids are disposed between the intermediate dams and between the first and second end dams and adjacent ones of the intermediate dams. The voids are located radially inwardly of the continuous annular section and are formed by removing material from a split rolled ring rolled from barstock or a rod.

  • Patent number: 7008181
    Abstract: An annular air baffle disposed in a cavity of a rotatable gas turbine engine part includes an annular split ring supporting a plurality of circumferentially spaced apart fins. The cavity is closed at a radially outer diameter and open at a radially inner diameter of the part. The ring and the fins may be integrally formed in one piece. The fins may have common surfaces with the ring and the common surfaces may be circular cross-sectional surfaces of the ring and radially outer rounded corners of the fins. The fins may have triangular cross-sectional shapes with first, second, and third sides, rounded first radially inner corners between the first and second sides, rounded second radially inner corners between the second and third sides, and the radially outer rounded corners between the first and third sides. The fins may extend radially inwardly from the annular split ring.

  • Patent number: 7000838
    Abstract: A method for processing scanned code data, including a plurality of strings, to determine whether the scanned code data is part of a valid code begins by examining a first string of a first scanned code data. A cluster is opened with the first string if the first string contains a start pattern. At least one valid middle portion of the first string is identified and a transition position count associated with the at least one valid middle portion is stored. A second scanned code data is searched for a second string matching at least part of the first string in the cluster. If a match is found, then the second string is added to the end of the cluster. The cluster is closed upon detection of a stop pattern and is then decoded.

  • Publication number: 20040064252
    Abstract: A method and system for processing pulse signals within an inertial device is provided. The inertial device may have inertial sensors, such as accelerometers and gyroscopes. The inertial sensors may output signals representative of a moving body's motion. The signals may require correction due to imperfections and other errors of the inertial sensors. The inertial device may receive signals from the inertial sensors and process the signals on a signal-by-signal basis so that when processing the signals, the inertial device at least recognizes which sensor output a signal and when the signal was output. The inertial device may then correlate signals that were output from the inertial sensors at selected times in order to transform the signals into a desired navigational frame of reference.

  • Patent number: 6432486
    Abstract: A method treats an article and more specifically an aircraft surface in order to prevent icing and to provide a coating that emits very low volatile organic compounds (VOC) during application and setting. Icing on critical aircraft surfaces creates dangerous conditions that impair the stability of the aircraft. The specific areas are referred to as “cold-soak” conditions and some areas on the “leading edges” of the wings. The invention eliminates icing on these surfaces. Ice will not form on the surface of certain polymer coatings with low surface energy such as Teflon. This is a consequence of the high contact angle between the water droplet and the surface that establishes a non-wetting surface. The invention implements such coatings and a deposition process. The coating may be used for other objects such as automobiles, consumer products, such as refrigerators, stoves, etc.
