Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
155 words
A weighing system comprising: A. a foundation member; B. a weighing platform; C. at least one pair of load cells, each having at least two strain-sensitive resistance elements, one being positioned to increase in resistance with applied load and the other being positioned to decrease in resistance with applied load; D. said pair of load cells being electrically connected wherein resistance elements of a first load cell of said pair of load cells increases in resistance with applied load, form, with resistance elements of the second load cell of that pair which likewise increase in resistance with applied load, the opposite legs of an electrical bridge, and, resistance elements of said load cells which decrease in resistance with applied load form, respectively, the other two opposite legs of said electrical bridge; and E. indicating means responsive to an electrical output from said load cells for indicating the sum of weight sensed by said load cells.
