A highly time resolved impedance spectroscopy that enhances the measurement of the dynamics of non-stationary systems with enhanced time resolution. The highly time resolved impedance spectroscopy includes an optimized frequency , rich a.c. or transient, voltage signal is used as the perturbation signal non-stationary time to frequency transformation algorithms are used when processing the measured time signals of the voltage and current to determine impedance spectra which are localized in time; and the system-charachterizing quantities are determined from the impedance spectra using equivalent circuit fitting in a time-resolution-optimized form.

Why it's free to use
- Filed September 29, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 29, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 29, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
