  • Method, Centralized Control Device, and System for Charging Service
    Publication number: 20110055063
    Abstract: In a service charging method, a centralized control point in Service Oriented Architecture (SOA) receives a service request from a service consumer. The centralized control point invokes a requested service for the service consumer according to the service request. The centralized control point generates a Call Detail Record according to an invoked result of the service.

  • Mathematical model useful for determining and calibrating output of a linear sensor
    Patent number: 7124047
    Abstract: The present invention relates to a method of analyzing accuracy of linear sensor output based on a theoretical prediction of the output model. The method comprises steps of: analyzing a statistically significant number of linear sensors to obtain operating profiles at two or more operating conditions; individually testing a linear sensor to obtain at least four data points; developing a theoretical prediction of the output model for each operating condition from the four data points; and comparing accuracy of the relationship between the theoretical prediction of the output model to sensor output in the operating profile corresponding to a given input for the same operating condition. Also disclosed are calibration algorithms associated therewith, as well as mechatronic units and further assemblies therefrom.
