Claim 1:
2. The method of claim 1, further comprising:
generating, by the first load sensor, load signals corresponding to loads applied to the first load sensor at a plurality of times prior to the first time;
determining, by the first load sensor, estimated values of the loads applied to the first load sensor at each of the plurality of times;
calculating, by the first load sensor, a plurality of errors based at least in part on the loads applied to the first load sensor and the estimated values of the loads applied to the first load sensor;
determining that values of each of the plurality of errors are zero;
selecting, by the first load sensor, at least a second set of bits based at least in part on the errors, wherein the second set of bits is encoded according to the binary code,
wherein a first digit of the first set of bits is zero,
wherein a second digit of the first set of bits is one, and
wherein a plurality of digits following the second digit represent values of zero for each of the plurality of errors according to the binary code;

transmitting, by the first load sensor to the computer system, at least the second set of bits; and
determining, by the computer system, that the load on the platform did not change for at least the plurality of times prior to the first time based at least in part on the second set of bits.
