  • Patent number: 11940320
    Abstract: A load sensor compares generated values of load signals to predicted values of the load signals. Where an error between a generated value and a predicted value is less than a threshold, a value of zero is transmitted by the load sensor to an external systems, in an encoded stream of bits, and the error are used to calculate a predicated value of a next load signal, such that insubstantial changes in loading resulting in small errors are not transmitted to the external system. Where an error between the generated value and the predicted value exceeds the threshold, however, a value representative of the error is transmitted to the external system, in an encoded stream of bits. The external system processes the stream of bits to calculate the error, to determine that an item has been placed on a storage system or removed therefrom, or to identify the item.
