A method for characterizing a suspension with particles floating therein which method comprises the steps of generating an acoustic actuation signal and registering an acoustic reflected signal. Further a first dataset is , calculated on the basis of the reflected signal the dataset containing , information which represents an autocorrelation function as a function of time of the reflected signal. Thereupon, first datasets are combined into a second cumulated dataset, which represents a sum of the autocorrelation functions which correspond with the first datasets. Finally a representation of a , particle size distribution is determined by solving this representation from an expression …

Why it's free to use
- Filed May 27, 2003 and granted December 18, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 27, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 27, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
