Weighing scales person recognition procedure measures weight and bioelectric impedance for comparison and update with stored averages

摘要

A weighing scales (1) person recognition procedure measures the weight (4) and bioelectric impedance (3) or another physical characteristic using multiple frequency or complex amplitude and phase measurement (12, 13), compares (10) them with stored average values to recognize the person and updates the stored average. Independent claims are included for weighing scales using the procedure.
