  • Patent number: 11915866
    Abstract: An enhanced safety coil that prevents crack formation and propagation to the coil windings from external sources and prevents exposure to fuel is provided. The enhanced safety coil may be used in a solenoid operated gas admission valve (SOGAV), and includes a plastic encapsulation body having at least one body de-stress feature, a coil wound on the plastic encapsulation body, a sleeve forming an outermost side protective wall configured to accommodate the plastic encapsulation body and coil therewithin, and potting provided between the plastic encapsulation body and the sleeve to seal the coil therein. The body de-stress feature is configured to reduce at least one of a formation or a propagation of a crack through the potting to the coil. The plastic encapsulation body forms retention latches configured to mate with a stator.

  • Patent number: 6810332
    Abstract: A method for computing complexity, confidence and technical maturity indices for the evaluation of a reservoir is disclosed. The method comprising the steps of (a) making estimates of reservoir components which are associated with a subsurface reservoir evaluation; (b) making estimates of confidence values for the estimates of the reservoir components; and (c) computing an evaluation index for the evaluation of the reservoir based upon at least one of the estimates of the reservoir components and the estimates of the confidence values. Complexity and confidence scores are assigned to the respective estimates of the reservoir components and estimates of confidence values. These scores are combined to produce complexity and confidence indices. This evaluation tool is intended to help improve the assessment of the reliability of probabilistic reservoir production forecasts. The tool provides an indicator of the reliability of the forecast production profiles and reserves estimations.

  • Patent number: 6560770
    Abstract: A method and apparatus are provided for extending the behavior and attributes of applications designed using a fourth generation language (4GL) programming tool. Specifically, a 4GL programming tool is provided that allows application designers to specify the implementation classes of the components that are used in the applications that they design using the 4GL programming tool. The implementation classes thus specified may define attributes and behaviors not supported by the corresponding component implementations provided with the 4GL programming tool. During runtime, methods in the specified implementation classes are invoked. To correctly invoke the methods of user-specified implementation classes, the interfaces of the methods must be known to the entity performing the invocations.

  • Patent number: 6538180
    Abstract: Pea seeds, produced from peas of the rug3rug3 genotype, substantially lacking plastidial phosphoglucomutase activity which have higher sucrose levels at the end of the vining period and may be vined over and extended period compared to conventional vining varieties are provided. Polynucleootides encoding pea plastidial phosphoglucomutase useful for altering the sucrose and starch content of plants, particularly peas, are also disclosed.

  • Patent number: 6083505
    Abstract: An immunogen/vaccine adjuvant composition containing an immunogen in an amount effective to stimulate an immune response and as a vaccine adjuvant a 1H-imidazo[4,5-c]quinolin-4-amine in an amount effective to increase the immune response to the immunogen.
