Abstract
A Point-Of-Sale (POS) device detects vibrations produced from equipment in its operational environment. The vibrations are identified and one or more filters produced to remove the vibrations when the POS device is used to improve the accuracy of the POS device.
Claims8
A method, comprising:
- identifying a frequency produced on a load cell, when a state of the load cell indicates the load cell is not in use, by finding a center frequency produced on the load cell that substantially matches a vibrational frequency for a vibration at a vibrational peak for the vibration and a width frequency wide enough in frequency to span the vibrational peak;
- recognizing the frequency as noise;
- and
- adjusting a filtering operation that executes to modify signals produced by the load cell to remove the frequency for at least a portion of the width frequency from the signals produced by the load cell when the frequency is present, the adjusting performed on a scale having a weigh plate including the load cell amongst a plurality of load cells.
