Claim 4:
5. A method comprising:
determining, by a first load sensor, a first estimated value of a load applied to the first load sensor at a first time;
determining, by the first load sensor, a second measured value indicative of a load applied to the first load sensor at a second time, wherein the second time follows the first time;
calculating, by the first load sensor, a second estimated value of the load applied to the first load sensor at the second time, wherein the second estimated value is calculated based at least in part on the first estimated value;
calculating, by the first load sensor, a first error based at least in part on a difference between the second measured value and the second estimated value;
determining, by the first load sensor, that the first error is less than a predetermined threshold;
in response to determining that the first error is less than the predetermined threshold,
transmitting, by the first load sensor, at least a first set of bits to a computer system over one or more networks, wherein the first set of bits represents at least a value of zero at the first time;

determining, by the first load sensor, a third measured value indicative of a load applied to the first load sensor at a third time, wherein the third time follows the second time;
calculating, by the first load sensor, a third estimated value of the load applied to the first load sensor at the third time, wherein the third estimated value is calculated based at least in part on the second estimated value and the first error;
calculating, by the first load sensor, a second error based at least in part on a difference between the third measured value and the third estimated value;
determining, by the first load sensor, that the second error is not less than the predetermined threshold;
in response to determining that the second error is not less than the predetermined threshold;
transmitting, by the first load sensor, at least a second set of bits to the computer system over one or more networks, wherein the second set of bits represents at least one multiple of the predetermined threshold; and

calculating, by the computer system, a change in the load applied to the first load sensor based at least in part on the value represented by the second set of bits.
