Patent ID: 7373735

Claim:
A device for rapid hardware sizing, comprising: a ruler-like body having a fixed end and a distal end, and including (i) a fixed jaw at said fixed end and (ii) a sliding jaw opposite said fixed jaw, said sliding jaw being slidably connected to said ruler-like body such that said sliding jaw slides there along from a point immediately adjacent to said fixed jaw at said fixed end, to a proximity of said distal end; a digital logic calculation and display means secured to said sliding jaw of said ruler-like body, such that said digital logic calculation and display means moves along said ruler-like body with said sliding jaw; measuring means in communication with said digital logic calculation and display means, for measuring a distance between said fixed jaw and said sliding jaw, whereupon said distance is then electronically communicated to said digital logic calculation and display means and selectively displayed thereon; and an electronic nut sizing selection means with said digital logic calculation and display means, to enable said digital logic calculation and display means to (i) automatically discriminate between metric and British units of measurement relative to said distance, and (ii) selectively and automatically calculate and display a correct tool size for manipulating the nut in one of said metric and British units of measurement as automatically discriminated by said digital logic calculation and display means.
