Patent ID: 7375293

Claim:
A WIM-II device comprising; a) at least one transducer pad, said pad having at least one transducer group with transducers positioned essentially perpendicular to the direction of travel, each transducer group positioned at a pre-defined distance from each other in a direction essentially parallel to the direction of travel; b) at least one pad microcomputer on each transducer pad, said pad microcomputer using a means for calculating first output signal indicative of weight, second output signal indicative of time, and third output signal indicative of speed; c) at least one host microcomputer in electronic communication with each pad microcomputer, said host microcomputer using a means for calculating at least one unknown selected from the group consisting of individual tire weight, individual axle weight, axle spacing, speed profile, longitudinal center of balance, and transverse center of balance; d) a network communication system for transferring data between said pad microcomputer and said host microcomputer.
