Abstract
Abstract A scale includes an arm system movable about and fixedly secured to a fulcrum. An output detector is coupled adjacent to one end of the arm system. A load structure is utilized to position an item thereon which is to be weighed by the scale. A strain sensor is fixedly connected adjacent the other end of the arm system and the load structure. The strain sensor and fulcrum are formed of resilient material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A scale comprising: an arm system movable about and fixedly secured to a fulcrum; an output detector coupled adjacent to one end of said arm system; a load structure for positioning an item to be weighed thereon; and a strain sensor fixedly connected adjacent the other end of said arm system and said load structure, said strain sensor and said fulcrum each being formed of a pad of resilient material, each pad being adhesively and permanently affixed to said arm system and said load structure adjacent surfaces.
Claim 2
Dependent Claim
87 words
A scale comprising: an arm system movable about and fixedly secured to a fulcrum; an output detector coupled adjacent to one end of said arm system; a load structure for positioning an item to be weighed thereon; and a strain sensor fixedly connected adjacent the other end of said arm system and said load structure, said strain sensor and said fulcrum each being formed of a pad of resilient material, each pad being adhesively and permanently affixed to said arm system and said load structure adjacent surfaces.
Claim 3
Dependent Claim
16 words
