Device and method having automatic user recognition and obtaining impedance-measurement signals
First Claim
1. An apparatus comprising:
- a CPU and memory circuit being configured and arranged to store user-corresponding data in the memory circuit;
a platform, electrically coupled with the CPU and memory circuit, over which a plurality of electrodes are interleaved, include at least one pattern of interleaved Kelvin electrode pairs for the one foot, and are configured and arranged for engaging a user; and
the CPU and memory circuit and the plurality of electrodes being configured and arranged to;
while the plurality of electrodes are concurrently contacting a limb of the user to obtain a plurality of measurement signals from the plurality of electrodes, and based on the plurality of measurement signals, access the user-corresponding data stored in the memory circuit and therefrom automatically indicating recognition of the user, andbased on a plurality of impedance-measurement signals being obtained from the plurality of electrodes while contacting the user, generating signals corresponding to cardiovascular timings of the user.

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.
