Abstract
Abstract Systems for receiving the noise and/or exhaust emmisions transmitted from motor vehicle exhaust outlet arrangements. The motor vehicle transmitter of noise and/or exhaust emmissions have a modified tail pipe arrangement arranged for close coupling and transmission of the noise and/or exhaust emmissions to receiving means for collecting and processing the noise and/or exhaust emmissions. The receiving means extends along the length of the highway and attenuates the received noise and/or collecting and passing the received exhaust emmissions to processing means for recovering or purifying the exhaust emmissions. The duct portion of the receiving means instead or also utilized to provide transmission of electric power to specially designed types of electrically powered motor vehicles along the highway and also provide guidance where it is so desired to instrument the vehicle and duct.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
70 words
In combination: a highway; a duct which runs parallel to and along the length of said highway; and, means distributed continuously along said duct for attenutating noise, said means comprising material disposed below the highway surface and lining at least one inside wall of said duct, said material having sound absorptive characteristics in the audio frequency range below 5,000 cycles per second so that exhaust noise directed thereagainst is attenuated.
Claim 2
Dependent Claim
70 words
In combination: a highway; a duct which runs parallel to and along the length of said highway; and, means distributed continuously along said duct for attenutating noise, said means comprising material disposed below the highway surface and lining at least one inside wall of said duct, said material having sound absorptive characteristics in the audio frequency range below 5,000 cycles per second so that exhaust noise directed thereagainst is attenuated.
Claim 3
Dependent Claim
89 words
In combination: a highway; detector means for detecting a predetermined pollutant level at a point along said highway; display means positioned above said highway surface; said display means coupled to said detector means and responsive thereto when said predetermined pollutant level is detected by said detector means; and, wherein said detector means comprises a plurality of detectors positioned below the surface of said highway, each of said plurality of detectors positioned respectively in a plurality of duct sections of predetermined length extending consecutively along the length of the highway,
Claim 4
Dependent Claim
89 words
In combination: a highway; detector means for detecting a predetermined pollutant level at a point along said highway; display means positioned above said highway surface; said display means coupled to said detector means and responsive thereto when said predetermined pollutant level is detected by said detector means; and, wherein said detector means comprises a plurality of detectors positioned below the surface of said highway, each of said plurality of detectors positioned respectively in a plurality of duct sections of predetermined length extending consecutively along the length of the highway,
Claim 5
Dependent Claim
153 words
In combination in the surface of a lane of a highway: first means extending above the surface and along the length of the highway; second means extending above the surface and along the length of th highway; a depression extending below said highway surface and extending between said first and second meAns; said depression arranged to run off water gathering on said highway surface between said first and second means; said first and second means extending less than 1 inch above said highway surface and the cross sectional area of said depression is greater than the cross sectional area of said first and second means combined; and, said first means comprising a wall extending above said highway surface, said second means comprising a further wall extending above said highway surface, and said depression comprising a duct having outer wall surfaces coextensive with the inner facing wall surfaces of said first and second means.
Claim 6
Dependent Claim
153 words
In combination in the surface of a lane of a highway: first means extending above the surface and along the length of the highway; second means extending above the surface and along the length of th highway; a depression extending below said highway surface and extending between said first and second meAns; said depression arranged to run off water gathering on said highway surface between said first and second means; said first and second means extending less than 1 inch above said highway surface and the cross sectional area of said depression is greater than the cross sectional area of said first and second means combined; and, said first means comprising a wall extending above said highway surface, said second means comprising a further wall extending above said highway surface, and said depression comprising a duct having outer wall surfaces coextensive with the inner facing wall surfaces of said first and second means.
Claim 7
Dependent Claim
22 words
The combination according to claim 3 wherein said first means, said second means and said depressions are of substantially rectangular cross section.
Claim 8
Dependent Claim
45 words
The combination of claim 3 wherein said depression extends a first predetermined distance below said highway surface and said first and second means extend a further predetermined distance above said highway surface and wherein said further predetermined distance is less than said first predetermined distance.
Claim 9
Dependent Claim
39 words
The combination of claim 3 wherein said first means, said second means and said depression extend along axis parallel to the lane of said highway and at least a car length therealong where a car length equals 20 feet.
