Magnetometers under the road surface detect variations in the vertical and longitudinal horizontal components of the magnetic field over time in response to passing vehicles. A trajectory of these components in the phase space of these field components is regularized to obtain a magnetic signature. Magnetic signatures are compared using cross-correlation over arc length to identify vehicles. Inductance sensors can be used to detect vehicles and help determine the beginning and end of magnetic signatures.

Vehicle identification

Method and apparatus enable cutting out shapes (S) preset in moving sheet material () by locating coordinates of one or more fiducials (F,F. . . ) in the sheet material () with a vision system (). The fiducials (F,F. . . ) correspond to a pattern (P) for the preset shape (S). A cutting system () superimposes the pattern (P) relative to the located one or more fiducials (F,F. . . ) for cutting out the preset shape (S) while the vision system () is concurrently locating subsequent one or more fiducials (F,F. . . ) in the moving sheet material (). The concurrent processes of cutting and locating subsequent fiducials (F,F. . . ) are repeated substantially continuously. Preferably, using two or more fiducials (F,F. . . ), distortion is detected and the pattern (P) can be remapped before cutting for accurate superposition of the pattern (P) and distorted preset shape (S).
