Patent

CA 2039282

Abstract The device utilizes two sensors (1, 7) of identical specification, and a light source (3), all of which mounted to a single bracket and directed at the road surface (2) in such a way that the beam from the source is reflected back at the sensors; the sensors are wired into a comparator (8) of which the output signal is used to pilot the activation of an alarm (6), and becomes operative whenever the signals from the two sensors become dissimilar by reason of the different luminous intensities and/or wavelengths in the beam when reflected in part by the natural road surface (2), and in part by the white or yellow lines (4) bordering a traffic lane or a hard shoulder.
