1. A method for processing sensor signals representing an event in an absorbent article, the method comprising: receiving sensor signals from a sensor representing one or more events in an absorbent article; processing the sensor signals to determine a characteristic of at least one event in the absorbent article, wherein processing the sensor signals includes identifying automatically the sensor signals representative of each individual event and, from the sensor signals representative of each individual event: (i) generating a representative vector for that event; (ii) allocating weightings to the representative vector to generate a weighted representative vector for that event; and (iii) allocating an event characteristic to the weighted representative vector for that event.
