Abstract :
We propose the computation of the recurrence times of unstable periodic orbits for pattern detection in biosignals. This approach can be applied to all time series which are part of a dynamic system with a few degrees of freedom. No template has to be given. As an example we show extraction of breathing patterns out of the thoracic impedance signal of a preterm infant during periodic breathing
