Abstract
Aspects of the present disclosure are directed to a CPU and a memory circuit that has user-corresponding data stored on the memory circuit, and a platform over which a plurality of electrodes are interleaved, and configured for engaging the user. While the plurality of electrodes is concurrently contacting a limb or other extremity of the user, measurement signals are obtained from the plurality of electrodes. Based on a plurality of impedance-measurement signals being obtained from the electrodes, signals are generated that correspond to cardiovascular timings of the user. In such aspects of the present disclosure, pulse characteristic signals are determined based on the plurality of impedance-measurement signals. One of the pulse characteristic signals is extracted, and used as a timing reference to extract and process another pulse characteristic signal.
