1. An apparatus comprising:
- a weighing scale;
a first user-physiological sensor including a heart-characteristic sensor configured and arranged to capture, from a user, a ballistocardiogram (BCG) signal for a plurality of a heartbeats from the user based on at least one of physical movement and mechanical output of the user'"'"'s heart while the user stands at a stationary position on the weighing scale;
a second user-physiological sensor configured and arranged to detect an indication of at least one of noise present in the BCG signal and a physiologic characteristic of the user, and to provide an output signal characterizing the detected indication;
a processor circuit configured and arranged to process the BCG signal by filtering motion and noise from the BCG signal due to user movement, using the output signal as provided by the second user-physiological sensor, and by using the BCG signal, as filtered, to generate a cardiac-indicative signal indicative of a condition of the user'"'"'s heart; and
an interface circuit configured and arranged to track changes for a cardiac condition, or indicate an abnormal cardiac condition, relative to the user'"'"'s physiologic characteristic using the cardiac-indicative signal from the processor circuit.

Abstract
Characteristics of a user'"'"'s heart are detected. In accordance with an example embodiment, a ballistocardiogram (BCG) sensor is used to detect heart characteristics of a user, and provide a BCG output indicative of the detected heart characteristics. The BCG output is further processed using data from one or more additional sensors, such as to reduce noise and/or otherwise process the BCG signal to characterize the user'"'"'s heart function.
