Devices, systems and methods to determine area sensor
First Claim
1. A weighing scale comprising:
- a) a platform that supports a load to be weighed by the scale;
b) one or more force transducers arranged beneath the platform, each configured to output a transducer force signal of the load thereupon;
c) an area sensor arranged above the platform and configured to output a plurality of area force signals representative of forces applied to respective spatial areas of the platform by the load;
d) a processor configured to determine a weight of the load placed on the platform and a location of the load with respect to the platform based on the transducer force signals and the area force signals; and
c) a computing device having the area sensor and a communications interface coupled to the processor, wherein the platform removably retains the computing device.

Abstract
A weighing scale includes a platform supporting a load. Force transducers beneath the platform output respective transducer force signals of the load. An area sensor above the platform outputs area force signals of load forces applied to respective spatial areas of the platform. A processor is configured to determine the load'"'"'s weight and location on the platform based on the transducer force signals and the area force signals. A method of weighing the load is also described. A method of monitoring the load includes measuring first transducer force signal(s) and first area force signal(s) of the load, and then repeatedly measuring second force signal(s) of the load using the transducer(s) or area sensor until the first and second signal(s) indicate a change in a weight or location of the load. A changed weight or changed location of the load is then determined using the measured second force signal(s).
