Patent ID: 7311675

Claim:
A system for activity monitoring, comprising: a sensor array comprising at least one sensor, wherein the sensor array transmits at least one analog signal indicative of the pressure applied to the at least one sensor; an analog-to-digital (A/D) converter, wherein the A/D converter receives the at least one analog signal and generates at least one digital signal indicative of the pressure applied to the at least one sensor; a processing device, in communication with the A/D converter, wherein the processing device: receives the at least one digital signal indicative of the pressure applied to the at least one sensor; converts the at least one digital signal into at least one pressure-indicative value; determines if a weight shift occurs at least in part by determining a difference between the at least one pressure-indicative value and at least one moving average of pressure-indicative values; and generates a weight shift percentage value, wherein the weight shift percentage value is based at least in part on the determined difference; and communicates the weight shift percentage value to a server in wireless communication with the processing device.
