  • Generating a product model
    Patent number: 10318937
    Abstract: An aspect of generating a product model includes extracting from source code of an application system at least one transaction definition associated with the source code. Each transaction definition describes a transaction in a product implemented by the source code. An aspect also includes dividing the transaction definition into one or more product categories, and obtaining a product component associated with one of the product categories from the source code so as to generate the product model. The product component includes at least one product parameter associated with the product category, and the product model includes an association relationship between the product category and the at least one product parameter.
    Type: Grant

  • Symmetrical clock crystal oscillator circuit
    Patent number: 5455542
    Abstract: An oscillator circuit provides a symmetrical signal without halving the frequency of a crystal oscillator 12. The input 14 of the crystal oscillator 12 is low pass filtered, and the output 18 of the filter 16 is differential voltage compared with the input 14 of the crystal oscillator 12. The output 22 of the differential voltage comparator 20 is symmetrical and of the same frequency as the crystal oscillator 12. The crystal oscillator 12 is preferably a Pierce oscillator.
