Patent ID: 7381910

Claim:
A sensor frame for generating a weight signal of a curved object, the sensor frame comprising: a pair of spaced sidewalls defining a receiving area for the curved object; a bottom surface connected between the spaced sidewalls; a deflection tab cooperable with the bottom surface, the deflection tab being deflected relative to the spaced sidewalls upon an application of weight to the sidewalls; a strain gauge secured to the deflection tab, the strain gauge outputting a weight signal corresponding to the weight of the curved object according to a deflection amount of the deflection tab; and support structure cooperable with the spaced sidewalls, the support structure supporting the curved object in line with a load centerline regardless of a size of the curved object, wherein the support structure comprises pin supports affixed between the spaced sidewalls, the pin supports being arranged in a substantially V-shape across a length of the sidewalls.
