  • Method for ascertaining an internal resistance of an electrical energy accumulator
    Patent number: 10288695
    Abstract: A method is described for ascertaining an internal resistance of an electrical energy accumulator. For this purpose, an analog voltage signal and an analog current signal are subjected to an analog to digital conversion and subsequently to band-pass filtering in order to obtain filtered voltage values and filtered current values. These are then checked with regard to different calculation prerequisites, whereupon a zero-phase resistance is calculated. Then, the calculated zero-phase resistance is supplied as internal resistance.
    Type: Grant

  • Database based timing variation analysis
    Patent number: 9245071
    Abstract: A method for timing analysis of a circuit design includes, for each group of one or more instances of a cell of a cell library in the circuit design, determining timing related data for the group according to circuit context of the group in the design. The context includes at least one of a path depth, an output load, and an input slew rate. The determined timing related data are applied to analyze the circuit design.
