Fecha de publicación: 03/12/2015 Fuente: WIPO "hive" A system and method for estimating the differential change in weight of an object by comparing the output of one or more load cells measuring only a portion of the object's weight over time. The system includes one or more load cells supporting a portion of the weight of an object, advantageously not requiring the full weight of the object on the weight sensing system. The method includes taking multiple readings of a partial weight over time and calculating the delta between measured values and historical values. The method includes input from a user which identifies the object being measured, the configuration of the system, and the preferred value of a conversion factor to calculate an increase or decrease of the entire object's weight either by a percentage or by a unit of measure.
