the disclosed systems and methods allow the weight and relative position of an object on a weighing surface to be simultaneously determined using a circuit that does not require pre - programed tables and that can be used in an analog or digital environment . one example system includes first , second , third , and fourth load cells having respective first , second , third , and fourth strain gauges . the strain gauges are configured to measure strain at the load cells caused by the object on the weighing surface . the system also includes circuitry configured to simultaneously determine weight and position of the object on the weighing surface , and a display that reports the weight of the object , a longitudinal position of the object , and a lateral position of the object .
