Highway sign system

Claim 2

A remotely controlled sign system for informing motorists of limited access highways of the facilities available at each exit, said system comprising a signboard having a substantially vertical face, a plurality of individual panels in said signboard face, a plurality of lighting means in each panel, each panel having a translucent pane with indicia thereon, a power circuit means for each lightiNg means, said power circuit means being connected to each said means by individual first switch means, relays to operate said first switch means, a remotely located power source, second switch means for each relay also remotely located to operate said relays and said first switch means responsive thereto.

Claim 3

A system as in claim 1 wherein said first power source is D.C. and said second power source is an A.C. source.

Claim 4

A system as in claim 1 including a detector means in the locale of said second switching means, said detector means adapted to signal when said lighting means is on.

Claim 5

A system as in claim 3 wherein said first power sources connected to said lighting means are D.C. power sources and said second power sources connected to said relays and said detector means are an A.C. source.

Claim 6

A system as in claim 4 wherein said detector means comprises a control rectifier operated by said D.C. power source, said rectifier being connected to a photodetector adapted to be activated by said lighting means, a detector element in the locale of said second switching means and adapted to be activated by a signal from said photodetector.

Claim 7

A system as in claim 5 including an oscillatory means controlled by said photodetector for providing an oscillatory signal to activate said detector element; said detector element includes a tuned detector and a lamp in series such that said oscillatory signal activates said tuned detector which activates said lamp.

Claim 8

A system as in claim 5 wherein said second switching means functions to turn said lighting means on in a first position and allows said detector means to operate in said second position.

Claim 9

A remotely controlled sign system for informing motorists of limited access highways of the facilities available at each exit, said system comprising a signboard having a substantially vertical display surface, said surface comprising a plurality of individual advertising panels with indicia thereon, illuminating means associated with each panel to illuminate the indicia on each panel, each illuminating means having a separate power circuit and a control circuit means remote therefrom for turning said illuminating means on and off and means associated with said individual advertising panels for signalling said remote controller whether the individual advertising panel is illuminated.

Claim 10

A remotely controlled sign system for informing motorists of limited access highways of the facilities available at each exit, said system comprising a signboard having a substantially vertical display surface, said surface comprising a plurality of individual advertising panels with indicia thereon, illuminating means associated with each panel to illuminate the indicia on each panel, each illuminating means having a separate power circuit and a control circuit means remote therefrom for turning said illuminating means on and off and means associated with said individual advertising panels for signalling said remote controller whether the individual advertising panel is illuminated.

Claim 11

A system as in claim 8 including means for supporting said signboard above the ground.

Claim 12

A system as in claim 8 wherein said control circuit means comprises a D.C. circuit means including said power source connected to said illuminating means for activating the same, a relay in said D.C. circuit, an A.C. circuit including a power source, a detector circuit and a switch and adapted to activate said relay for activating said D.C. circuit and said illuminating means, said detector circuit including a photodetector means activated by said D.C. circuit and adapted to cause a pulse signal in said A.C. circuit if said illuminating means is lit.

Claim 13

A remotely controlled illuminated sign system for informing users of limited access highways of the facilities available at each exit, said system comprising two signboards, each one adapted to face opposite lanes of oncoming traffic, said signboards having a substantially vertical display surface, said surface comprising a plurality of individual advertising panels with advertising indicia thereon, an illuminating circuit means associated with each panel for illuminating said indicia on each panel, each illuminating circuit means having its own power supply, a central control circuit means for energizing said illuminating circuit means associated with each said advertising panel to light corresponding panels on both signboards, and a plurality of individual advertiser circuit means remote from said central control circuit means and said signboards for activating said central control means.

Claim 14

A remotely controlled illuminated sign system for informing users of limited access highways of the facilities available at each exit, said system comprising two signboards, each one adapted to face opposite lanes of oncoming traffic, said signboards having a substantially vertical display surface, said surface comprising a plurality of individual advertising panels with advertising indicia thereon, an illuminating circuit means associated with each panel for illuminating said indicia on each panel, each illuminating circuit means having its own power supply, a central control circuit means for energizing said illuminating circuit means associated with each said advertising panel to light corresponding panels on both signboards, and a plurality of individual advertiser circuit means remote from said central control circuit means and said signboards for activating said central control means.

Claim 15

A system as in claim 11 wherein each individual advertiser circuit means has two indicator means therein, each indicator means corresponding to said advertiser''s panels on the two respective signboards, said illuminating circuit means and said control circuit means adapted to activate said indicator means to inform the advertiser if his panels are illuminated.

Claim 16

A system as in claim 1 where said central control circuit means, upon receiving a signal from either of said signboards, is adapted to send a frequency signal to said advertiser circuit means to activate said indicator means.
