Patent ID: 7669486

Claim:
A weight sensing device, comprising: [1] a base; [2] a cover having a load bearing surface, a heel end, and a toe end; [3] a first load cell having a base end and a cover end, wherein [4] the base end of the first load cell is attached to the base, [5] the cover end of the first load cell is attached to the cover, and [6] the first load cell is able to flex in response to a load positioned on the load bearing surface of the cover; [7] a second load cell having a base end and a cover end, wherein [8] the base end of the second load cell is attached to the base, [9] the cover end of the second load cell supports, but is not attached to, the cover, and [10] the second load cell is able to flex in response to a load positioned on the load bearing surface of the cover; and [11] an analyzing circuit which is electronically connected to the first and second load cells, wherein [12] the first and second load cells each send a weight signal to the analyzing circuit in response to flexing of the load cells caused by a load positioned on the load bearing surface of the cover.
