Abstract
One or more computer processors obtain one or more time-dependent signals with one or more sensor pairs in a sensing system, respectively, wherein each of the one or more time-dependent signals are obtained as a differential signal of a respective pair of the one or more sensor pairs by successively sensing a reference liquid and each liquid in a set of liquids to be characterized with the respective pair; extracting one or more sets of features from one or more portions of the one or more time-dependent signals, respectively, each of the one or more portions including a signal portion obtained while sensing each liquid in the set of liquids with said respective pair; and characterize each liquid in the set of liquids based on the one or more extracted sets of features.
