Abstract: Speed and acceleration calculation and measuring methods and devices based on a regularization algorithm are disclosed. Speed and acceleration are calculated using the following steps: (1) acquiring position data or displacement data; and (2) using the position data or displacement data to calculate the speed and the acceleration with a disclosed regularization method. The disclosed methods and systems avoid the issue of noise amplification that arises when speed and acceleration are measured by existing speed and acceleration devices at high sampling rates. Noise amplification is prevented by first expressing the relationship between position data or displacement data and speed or acceleration into a typical Volterra integral equation of the first kind, and then using the disclosed regularization method to calculate speed and acceleration, thus suppressing noise amplification and accurately extracting speed and acceleration signal values.

Abstract: A method and apparatus for division of revenue of communication among different proprietors is provided in this invention, where the division of revenue among the different proprietors is performed by a gateway office, wherein the gateway office will set a source parameter and a destination parameter respectively from the source and the destination when a call goes through the gateway office; Judge the two parameters to get a revenue zone index; Judge the value of the revenue zone index, and modulate the revenue zone index to get a revenue class index; The gateway office generates contents related to the revenue class index; A central memory receives all these contents, adds an increment of each counter of the revenue class memory related to the revenue class index to a corresponding counter and carries out multiple safety mechanisms; Output the information in the revenue class memory to a storage medium for storing, then output it to a billing center for revenue sorting.
