Classification: CPC G  H | IPC G  H

Claim 4:
5. A method comprising:
configuring a first load sensor to transmit load signals for a first duration and in accordance with a first interval;
receiving, from the first load sensor, a first load signal, wherein the first load signal indicates a force applied to the first load sensor by a first platform at a first time and wherein the first load signal is transmitted by the first load sensor for the first duration;
receiving, from the first load sensor, a second load signal, wherein the second load signal indicates a force applied to the first load sensor by the first platform at a second time, wherein the second load signal is transmitted by the first load sensor for the first duration, and wherein a time between the first time and the second time is the first interval;
detecting a variation in loading on the first platform based at least in part on the first load signal and the second load signal;
in response to detecting the variation in the loading on the first platform,
configuring the first load sensor to transmit load signals for a second duration and in accordance with a second interval, wherein at least one of the second duration is longer than the first duration, or the second interval is shorter than the first interval;

receiving, from the first load sensor, a third load signal, wherein the third load signal indicates a force applied to the first load sensor by the first platform at a third time, wherein the first load signal is transmitted by the first load sensor for the second duration;
receiving, from the first load sensor, a fourth load signal, wherein the fourth load signal indicates a force applied to the first load sensor by the first platform at a fourth time, wherein the fourth load signal is transmitted by the first load sensor for the second duration, and wherein a time between the third time and the fourth time is the second interval;
identifying a first item based at least in part on the third load signal and the fourth load signal; and
storing information regarding a transaction involving the first item in at least one data store.
