Lung Function

We are working with the Woolcock Institute to develop improved anomaly detectors for breathing cycles using the forced oscillatory technique [1]. This improves the quality of the data collected and hence the utility of the technique.

Cardiology

We developed analog VLSI chips for the low power classification of abnormal heart rhythms from intracardiac leads [1]. The scheme combined morphology and timing information [2] to achieve better accuracy than previous techniques. The feasibility of this approach for implantable defibrillator devices was demonstrated.
