ABSTRACT/SUMMARY
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 lane on a roadway for an automobile, the center of an airstrip or landing strip for an aircraft, or the center of a water channel for a boat. It further informs the operator of a car of the route number, the pilot of an airplane of the airstrip identification, or the pilot of a boat of channel name, latitude and longitude, the vehicle speed, and compass direction. Presence of the vehicle in an incorrect location, lane or going the wrong way sets off an audible alarm. Provision is also made to include approaching intersections, and crossroads, changes to alternate routes, and on roadways approaching commercial establishments. The information is visible on a computer screen in full view of the operator and is functional regardless of the time, day or night, weather conditions, visibility or electrical interference. A metal detector, magnetometer, senses passive elements, such as a ferrous wire but not limited to that cross section or material, imbedded in the center of the lane or airstrip or submerged metal ribbon but not limited to that material and cross section, for a boat. In the case of a boat, a sonar device senses the passive element, submerged in the water in the center of the channel. Coded (bar code) information in passive elements imbedded in the road alert the operator of approaching intersections and approaching commercial establishments. A metal detector, magnetometer detects the imbedded passive elements. The general configuration is shown in FIG. 1a for a car, FIG. 1b for a boat and FIG. 1c for an aircraft. FIG. 2 shows a simplified diagram for a metal detector. FIG. 3 shows a simplified block diagram for a car or aircraft. FIG. 4 shows a simplified block diagram for a boat. The system is independent of outside conditions and is functional, day and night.

GENERAL/DETAILED
Preferred Embodiment
Referring first to FIG. 1a of the drawings, the basic system for an automobile is shown by illustration and annotation. Imbedded in the lane of the roadway 1 are bar codes 3 and a cable 4. Mounted on the vehicle 2 is a 2-coil ferrous metal detector 5. The signal output of the detector is electrically connected 6 to the computer 7 which converts the signal for display on the computer screen 8 in full view of the operator. The annotations in 8 show in full view the information that the operator will see. Accordingly the operator can guide the vehicle safely in the middle of the lane being traveled.
Referring to FIG. 1b, in the center of the channel 1 are submerged the bar codes 3 and ribbon of metal 4. The ribbon of metal provides a broader surface to reflect the Sonar wave and would be a more reliable reflector of the said Sonar wave than a wire. Mounted in the boat 2 is a single frequency Sonar device 5. The Sonar's electrical output is carried by wire 6 to the computer 7. The signals are converted and displayed on the computer screen 8 in full view of the pilot, who accordingly can maintain the proper route in the channel.
Referring to FIG. 1c, the bar code 3 and cable 4 are imbedded in the airstrip 1. The metal detector 5 and the computer 7 are installed in the aircraft 2. The electrical output signal of the detector is carried by wire 6 to the computer 7 where it is converted for display on the computer screen 8 in full view of the pilot who accordingly can land or takeoff safely on the proper airstrip.
Referring to FIG. 2, the simplified diagram of a 2-coil metal detector is shown. The transmitting coil induces a current in the cable that in turn develops a magnetic field around the wire. The magnetometer, receiving coil detects the field.
Referring to FIG. 3, the system is shown in a simplified block diagram for a car or aircraft. Referring to FIG. 4, the system is shown in a simplified block diagram for a boat.
PRE-PROGRAMMING
Additional Embodiment
Car routes by number and name, commercial establishments and destination can be pre-programmed and stored in the computer memory. As the vehicle progresses on the route, the pre-programmed data is matched with the detected data, insuring that the correct route is being taken.
For aircraft, the location for lining-up prior to takeoff and the takeoff airstrip can be pre-programmed, insuring that the aircraft is in the designated location and taking off from the designated airstrip. On occasion there have been errors in aircraft location and takeoff that the tower was not able to discern and correct. The system would provide a backup for the pilot to insure a safe location and proper airstrip for takeoff.
For boats, channel name, successive locations on the route designated by latitude and longitude and compass direction can be pre-programmed and stored in the computer memory. Collisions and running aground will be avoided as the boat progresses on its route and the pre-programmed data is matched with the detected data.
