Claim 18:
19. The storage system of claim 18, wherein the computer system is configured to execute a method comprising:
determining a voltage level generated by at least one of the photovoltaic cells based on light energy absorbed by the at least one of the photovoltaic cells;
selecting at least one of a pulse duration or a pulse interval based at least in part on the voltage level;
receiving a first load signal from a first load sensor of the plurality of load sensors, wherein the first load signal indicates a force applied to the first load sensor by the platform at a first time, and wherein the first load signal has the pulse duration;
receiving a second load signal from the first load sensor, wherein the second load signal indicates a force applied to the first load sensor by the platform at a second time, wherein the second load signal has the pulse duration, and wherein the first time and the second time are separated by the pulse interval;
detecting a variation in loading on the upper surface of the platform based at least in part on the first load signal and the second load signal;
identifying an item based at least in part on the variation in loading; and
in response to identifying the item based at least in part on the variation in loading,
storing information regarding a transaction involving the item in at least one data store.
