    Abstract: Systems, apparatuses, and methods for the recognition and allocation of revenue generated by a subscription based pricing model or plan that is applied to a product or service. Embodiments respond to customer needs for a flexible and powerful revenue allocation engine to permit correct revenue distribution within a subscription economy and effectively trace changes to a revenue schedule and the resulting revenue recognition. Embodiments can efficiently react to changes to a subscription agreement and calculate a new distribution for a revenue schedule and its impact on revenue recognition and future revenue projections. In one embodiment, the systems and methods includes a revenue recognition/allocation engine that operates to evaluate the impact of “charge events” on revenue generation, taking into account relevant business rules and revenue recognition principles.

  • Patent number: 11631975
    Abstract: For Direct Current (DC) bus voltage control, a method generates a q-axis reference current from a DC voltage error that includes a DC voltage input modified by a DC bus voltage in a closed outer loop. The method further generates a d-axis reference current from the DC voltage error, wherein the second-order harmonic in the d-axis reference current is delayed from that in q-axis reference current by 90 degrees. The method generates a q-axis current from the q-axis reference current. The method generates a d-axis current from the d-axis reference current. The second-order harmonic in d-axis current is offset from the second-order harmonic in q-axis current by 90 degrees. The method controls the DC bus voltage of a voltage control plant to mitigate a second-order harmonic in the DC bus voltage with the second-order harmonics in the q-axis current and the d-axis current.
