Open the CIPO recordAbstract From the Canadian patent
A device for analyzing a transient waveform of the present invention is provided with a computation unit which analyzes the observed transient response waveform as an input adaptive type autoregressive model consisting of a linear function of regressive coefficients dependent upon material parameters or upon material parameters and material spectra. It can perform a rapid and accurate analysis of the transient response waveform observed through the incidence of pulse laser beams, promoting searches into the prime process of material changes.

Why it's free to use
- Filed September 26, 1990 and granted July 24, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 26, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 26, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
