Abstract

A method for communicating with a vehicle has a generator for producing a data stream that can indicate, street sign information, house number, lead vehicle information, traffic information, oncoming vehicle information, juxtaposed vehicle information, a voice channel, etc. vehicle information can indicate braking, low beam requests, direct or indirect traffic flow information, adjacency, partial adjacency, or presence of nearby vehicles, etc. This signal is generated by at least one of: the sign, house number, oncoming vehicle, lead vehicle, operator of the lead vehicle, operator of the oncoming vehicle, operator of the juxtaposed vehicle, a traffic control system. A device for generating such data streams is discussed, as well as, a device for receiving such data streams. Information pertinent to the people in the vehicles or operation of the vehicle can be modulated on the link.

Claims

1. A system for transmitting a message to a vehicle comprising:

a signaling device mounted about a building for providing a travel information signal relevant to driving said vehicle, said signaling device having a modulator for producing a main signal modulated and encoded according to the travel information signal, said main signal is further encoded to include at least one of;

building number, local utility usage, and adjustable signage, modulation being conducted at or above a critical flashing frequency or with a pulse duration that is human imperceptible;

a receiver mounted in said vehicle for receiving said travel information signal, said receiver having a luminance sensing device for producing a detection signal; and

a utilization device mounted in said vehicle and coupled to said receiver for using the detection signal.

5. A system according to claim 1 wherein said signaling device provides street number information, said modulator being operable to produce an optical signal modulated and encoded according to said street number information, and being conducted with an inter-pulse blank duration that is human imperceptible.

6. A system according to claim 5 wherein said main signal is further encoded to include location.

7. A system according to claim 6 wherein said signaling device is mounted on a post.

8. A system according to claim 1 wherein said main signal is further encoded to include at least one of:

energy price information, location, and fuel price information.

9. A system according to claim 1 wherein said main signal is further adapted to include at least one of:

error detection, error recovery, data redundancy, and signal recovery by the application of voting techniques to redundant data.

10. A system according to claim 8 wherein said utilization device comprises:

an analyzer for decoding said detection signal to produce a decoded signal.

11. A system according to claim 1 wherein said utilization device comprises:

an annunciator for producing a human-perceptible signal in response to said decoded signal.

12. A communications arrangement according to claim 1 wherein the receiver is in a standard orientation with respect to an anticipated location at which a vehicle might pass.

13. A communications arrangement according to claim 11 wherein the anticipated location is at least one of:

roadway, taxiway, parking position, and waterway.

14. A communications arrangement according to claim 1 wherein said building is one of:

post, pole, and sign.

2. A system according to claim 2 wherein said luminance sensing device has a narrow spectral response that is narrower than the visible spectrum.

3. A system according to claim 2 wherein said utilization device comprises:

an analyzer for decoding said detection signal to produce a decoded signal.

4. A system according to claim 3 wherein said utilization device comprises:

an annunciator for producing a human-perceptible signal in response to said decoded signal.

15. A communications arrangement wherein data is collected by luminance sensing apparatus located on vehicle, used to accumulate data pertaining to the price of fuel and location, optically encodes said data and radiated in essence in the visible spectrum, and relay these to a network that accumulates this information, tracks vehicle position and makes a calculation as to where the most efficient location to refuel is based on available information;

said calculation being made available to at least one member of a fleet of vehicles;

said data is optically encoded with an LED with a reflector mounted at a 45 degree to expected path from which vehicle arrives in plan view and oriented in a descending path inclined 15 degrees to level, in such a way as to intersect the middle of a vehicle in the position most likely to be occupied at least at one point in time by an oncoming vehicle, at a height of 1.5 m above ground, and

said sensing apparatus is a PIN diode, with a reflector, mounted about 1.5 m above ground, and in such orientation as to optimize capture of rays arriving from 45 degrees ahead of the vehicle, passenger side, and arriving from 15 degrees above the horizontal.
