Patent ID: 6980920

Claim:
A system for determining position, speed, direction and size of an object in motion, comprising: at least two sensors at fixed intervals between each other in at least one sensor arrangement; at least one processor; and at least one outcome device; wherein said at least two sensors send input signals to said at least one processor; wherein said at least one processor receives input signals from a series of said at least two sensors set at a fixed distance relative to each other, analyzes input signals from pairs of adjacent sensors of said at least two sensors from said at least one arrangement; and send output signal to said at least one outcome device; and wherein said at least one outcome device performs at least one action according to a set of predetermined rules; further wherein said at least one processor is able to treat either sensor of each sensor pair as the first or second sensor of said pairs of sensors, and analyzes said signals from said sensor pairs to sense objects in motion along said series of sensors; and further wherein said at least one processor analyzing state of input signals from said pairs of sensors to determine the directions, positions along said series of sensors, speeds, sizes, and numbers of said objects in motion, said sizes of said objects being relative to said fixed distance between adjacent sensors.
