1-16. (canceled)
An Point-Of-Sale (POS) device, comprising:
- a processor;
- a weigh plate;
- a spectra analyzer adapted and configured to:
- i) execute on the processor and ii) produce a frequency spectrum for a vibrational frequency;
- and
- a notch filter adapted and configured to i) execute on the processor and ii) remove the vibrational frequency from signals of a load cell when the vibration frequency is present in the signals by using the frequency spectrum and the vibrational frequency.
