Abstract

Systems, apparatus and methods for estimating a mass of an object by a mobile device are presented. The mobile device, which may be a smartphone, vibrates the mobile device both unloaded (without an object) and loaded (with an object) while measuring the unloaded and loaded vibrations. Next, the mobile device compares the unloaded and loaded vibrations and determines the mass of the object from the comparison.
