20100173076 | FABRICATION OF POLYANILINE NANOFIBER DISPERSIONS AND FILMS - A new method for forming stable polyaniline nanofiber colloids uses electrostatic repulsion to maintain dispersion of the nanofibers and prevent aggregation during synthesis of the nanofibers. The colloidal suspensions are formed directly from the reactants in solution maintained at a pH of about 1.0 to about 4.0 and a temperature of about 10° C. to about 100° C. with minimal or no stirring. Also set forth are new methods for forming ultrathin films of polyaniline nanofibers via self-assembly. | 07-08-2010 |

20120137014 | METHOD AND DEVICE FOR PROTOCOL IDENTIFICATION - A protocol identification method and a protocol identification device are provided. The protocol identification method includes acquiring a performance index of protocol characteristic information according to characteristic conditions of the protocol characteristic information; calculating identification probabilities of the protocol characteristic information employed by DPI under a preset statistical strategy according to a DPI identification result; determining an optimal sequence of all protocol characteristic information in a DPI identification library according to the performance index and the identification probabilities of the protocol characteristic information; and performing protocol identification on a received message according to the optimal sequence. The optimal sequence for protocol identification is determined according to the identification probabilities, the protocol characteristic information with a high match success probability may be matched first, and the protocol characteristic information with a high match failure probability may be matched later, which thereby improves the protocol match performance. | 05-31-2012 |

20130219464 | METHOD FOR STANDARDIZING COMPUTER SYSTEM ACTION - A method for standardizing computer system action, including: intercepting invoking command; obtaining data structure of the intercepted invoking command after intercepting the invoking command; determining the sponsor of the intercepted invoking command based on the data structure of the obtained and intercepted invoking command, and determining operation method and operation object of the intercepted invoking command; matching the sponsor, the operation method and the operation object of the intercepted invoking command with rules of standardizing computer system action, judging whether to allow executing the intercepted invoking command. The present disclosure determines the sponsor of the intercepted invoking command according to the data structure of the invoicing command, and can monitor comprehensively computer system. If only the sponsor is spiteful, the disclosure does not all allow executing the intercepted invoking command, thus detecting lawless operation comprehensively and effectively. | 08-22-2013 |

20140075161 | Data-Parallel Computation Management - Data-parallel computation programs may be improved by, for example, determining the functional properties user defined functions (UDFs), eliminating unnecessary data-shuffling stages, and/or changing data-partition properties to cause desired data properties to appear after one or more user defined functions are applied. | 03-13-2014 |
20140156847 | Service Allocation in a Distributed Computing Platform - The techniques and arrangements described herein provide for updating services, host operating systems and other applications while satisfying update domain constraints. In some examples, one or more controller modules may maintain a data structure including a plurality of server update domains, each server update domain including a set of machines of a plurality of machines of a distributed computing system which may be concurrently updated. The one or more controller modules may allocate the plurality of instances to the plurality of machines such that a number of server update domains is minimized. | 06-05-2014 |

20160051847 | FITNESS EQUIPMENT AND AUTOMATIC OXYGEN-GENERATING FITNESS EQUIPMENT - A fitness equipment and an automatic oxygen-generating fitness equipment are disclosed. The fitness equipment comprises a power unit, a sensor unit and an oxygen-generating assembly. The power unit comprises a belt drive turnplate, a belt and a magnetic wheel. Rotation of the belt drive turnplate drives the belt to operate so that the magnetic wheel is driven to rotate. The sensor unit is adapted to detect the belt drive turnplate and generate an activation signal when the belt drive turnplate is rotating. The oxygen-generating assembly comprises a control unit, a motor and an oxygen generator. The control unit is configured to receive the activation signal from the sensor so that the motor is activated to drive the oxygen generator to operate. The control unit may also control the equipment to switch between an oxygen-generating mode and a non-oxygen-generating mode. | 02-25-2016 |

20150185009 | DYNAMIC ATTITUDE MEASUREMENT METHOD OF STAR SENSOR BASED ON GYRO'S PRECISE ANGULAR CORRELATION - The disclosure discloses a dynamic attitude measurement method of a star sensor based on gyro's precise angular correlation. On the basis that a dynamic compensation is performed on each of the measurement exposure frames of the star sensor and a fixed star matching vector matrix having dynamic error and noise influence is obtained in a prior art, a transform matrix between every two adjacent measurement frames of the star sensor is precisely measured by a unit including three gyros fixedly coupled with the star sensor. The transform matrix correlates the matched vector matrixes of the adjacent measurement frames of the star sensor. Finally, a correlated measurement equation is established with a series of correlated measurement frames, which is corresponding to processing a series of measurement frames as a single measurement frame. | 07-02-2015 |
