ABSTRACT:
It is the object of this invention to provide a system that informs a vehicle operator that the vehicle is safely in the center of the proper lane of intended travel. It further informs the operator of specifics about the lane. Presence of the vehicle in an incorrect lane or going in the wrong way sets off an audible alarm. The information is visible on a computer screen in full view of the operator. It is functional regardless of the time, day or night, weather conditions, visibility or electrical interference. A metal detector senses passive elements imbedded in the center of the lane. For a boat the element is submerged in the proper channel and is sensed by a sonar device. Imbedded bar codes are the sources of the information. The general configuration is shown in FIGS.1a-1c. FIGS.2-4show simplified block diagrams for the system.
