Claim:
1. A method for detecting a liquid discharge event in an absorbent article, wherein said absorbent article comprises a sensor adapted to generate an electrical output signal representative of a degree of wetness of said absorbent article, wherein said electrical output signal is received by a processing unit, said method comprising the steps of: providing reference data obtained via collecting sensor output over a time period, wherein the provided reference data has both a sensor output component and a time component, and wherein the reference data is representative of a liquid discharge event; acquiring liquid discharge data over a time period, wherein the acquired liquid discharge data has both a sensor output component and a time component, and wherein the sensor output component is said electrical output signal; comparing said acquired liquid discharge data to said provided reference data to determine variations of the acquired liquid discharge data in relation to the provided reference data, wherein comparing comprises convoluting said liquid discharge data with said reference data; and detecting a liquid discharge event based on said comparison.
