Abstract
Abstract An illumination plotter for plotting illumination characteristics of thoroughfare lighting systems including a vehicle, an adjustable length, horizontally extending, supporting bar mounted on the top of said vehicle, and a pair of light intensity sensing devices mounted on opposite ends of the supporting bar. The sensing devices are connected to an amplifier carried in the vehicle, and the amplifier is connected to a recording system. The sensing devices each have convex, upwardly facing light-sensitive surfaces to obtain maximum exposure to light emanating from above.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
66 words
An illumination plotter apparatus comprising: a mobile vehicle; supporting means mounted on the upper portion of said vehicle; a plurality of light-sensing devices mounted on said supporting means in horizontally spaced relation to each other; each of said light-sensing devices comprising a hemispherical, upwardly facing exposed surface of light-sensitive material; and signal-responsive means mounted on the vehicle and responsive to signals developed by said light-sensing devices.
Claim 2
Dependent Claim
66 words
An illumination plotter apparatus comprising: a mobile vehicle; supporting means mounted on the upper portion of said vehicle; a plurality of light-sensing devices mounted on said supporting means in horizontally spaced relation to each other; each of said light-sensing devices comprising a hemispherical, upwardly facing exposed surface of light-sensitive material; and signal-responsive means mounted on the vehicle and responsive to signals developed by said light-sensing devices.
Claim 3
Dependent Claim
41 words
An illumination plotter apparatus as defined in claim 1 wherein said supporting means includes a plurality of channel extension bars horizontally movable with respect to said vehicle and each having one of said light-sensing devices mounted on the upper side thereof.
Claim 4
Dependent Claim
51 words
An illumination plotter apparatus as defined in claim 1 wherein said signal-responsive means comprises: amplifier means connected to each of said light-sensing devices; recorder means connected and responsive to said amplifier means; and at least one chart cooperating with said recorder means to portray indicia scribed thereon by said recorder means.
Claim 5
Dependent Claim
68 words
An illumination plotter apparatus as defined in claim 1 wherein said supporting means comprises: a pair of legs secured to said vehicle on the opposite sides thereof; an elongated, hollow top carrier adjustably connected to said legs and extending across the top of said mobile vehicle; and means slidably mounted on said top carrier and supporting said light-sensing devices for adjusting the horizontal spacing of said light-sensing devices.
Claim 6
Dependent Claim
33 words
An illumination plotter apparatus as defined in claim 1 wherein said light-sensing devices are cadmium sulfide photoresistor devices having a convex cadmium sulfide light-sensitive surface with the convexity of the surface facing upwardly.
Claim 7
Dependent Claim
69 words
An illumination plotter apparatus as defined in claim 1 wherein said mobile vehicle is an automatic vehicle having a rain rail on the sides of the vehicle adjacent the top thereof, and wherein said supporting means comprises: a pair of legs engaging said rain rail on the opposite sides of the vehicle and projecting upwardly therefrom; and an elongated top carrier having its opposite ends secured to said legs.
Claim 8
Dependent Claim
41 words
An illumination plotter apparatus as defined in claim 2 wherein said supporting means is further characterized in including a top carrier mounted on, and extending transversely across, said mobile vehicle and slidably supporting said channel extension bars in aligned, end-to-end relation.
Claim 9
Dependent Claim
53 words
An illumination plotter apparatus as defined in claim 7 wherein at least one of said light-sensing devices is mounted on each of said channel extension bars adjacent its end located most remotely with respect to the other of said channel extension bar, and includes an upwardly facing, convexly configured surface of light-sensitive material.
Claim 10
Dependent Claim
72 words
An illumination plotter apparatus as defined in claim 8 wherein said signal-responsive means comprises: an amplifier having a number of channels corresponding to the number of said light-sensing devices; signal-conveying electrical leads connecting the light-sensing devices with said amplifier; recorder devices corresponding in number to the number of said amplifier channels each connected to said amplifier; and chart means positioned adjacent said recorder devices for receiving traces scribed by said recorder devices.
Claim 11
Dependent Claim
29 words
An illumination plotter apparatus as defined in claim 9 wherein said vehicle is an automobile and said amplifier, recorder devices and chart means are positioned on the inside thereof.
