Title:
METHODS AND SYSTEM FOR OBTAINING A FORCE MEASUREMENT WITH REDUCED DRIFT EFFECTS
Document Type and Number:
WIPO Patent Application WO/2020/102071
Kind Code:
A3
Abstract:
Various methods and systems are provided for a drift-compensated force measurement. In one example, a method includes obtaining a single output voltage measurement from a strain gauge of an infant scale, the single output voltage reflective of a weight applied to the scale; obtaining a voltage measurement across each of four resistors of the strain gauge to determine four separate voltage measurements and determining a drift voltage based on the four separate voltage measurements; and outputting a corrected weight value determined based on a difference between the single output voltage and the drift voltage.
