Abstract
In accordance with an example embodiment, a body-weight sensing scale includes cardio-based physiological sensing circuitry to detect heart characteristics of a user, and provide outputs indicative of the detected heart characteristics. A processor circuit is arranged with the cardio-based physiological sensing circuitry to process data to provide a noise-reduced cardiogram signal which characterizes functionality/health of the user's heart.
Claims21
A body-weight sensing scale apparatus comprising:
- a weighing scale configured and arranged with a housing and a scale platform;
- user-physiologic sensors, including a first sensor and including a second sensor, configured and arranged to capture a cardiogram signal of a user from at least one foot of the user in real-time while the user is in an upright position and with said at least one foot of the user on the scale platform of the body weight sensing scale apparatus,
- the user-physiologic sensors including circuitry configured and arranged to detect and output an indication of at least one of noise present in the cardiogram signal and a physiologic characteristic of the user, by sensing and capturing a series of heart-signals from a user while the user stands on the scale platform at a stationary position, the series of heart-signals corresponding to the cardiogram signal based on a plurality of a heartbeats from the user;
- and
- a processor circuit configured and arranged to process the cardiogram signal and generate therefrom a noise-filtered cardiac-related signal indicative of a condition of the user's heart by filtering, from the cardiogram signal, noise that is due to user movement.
