Abstract

A smart groove seal integrating a communication system within a groove seal used to seal expansion joints and grooves formed in pathways or roadways. One embodiment of the smart groove seal embeds one or more illumination sources that emits visible and/or infrared light into a clear elastomeric expansion joint seal. The communication system includes an expansion joint seal having a selectable array on one or more light sources (such as LEDs and/or OLEDs) positioned within the expansion joint seal, a power supply, and a controller. The smart groove seal enhances the lighting of lanes on vehicular and pedestrian roadways and/or provides vehicular or roadway information to vehicular operators.

8. The pathway groove seal of claim 1, wherein the illumination sources are in communication with a remote power supply.

9. The pathway groove seal of claim 1, wherein the controller activates a selected group of the illumination sources under a predetermined set of conditions.

10. The pathway groove seal of claim 9, wherein the activated illumination sources transmit light to illuminate a portion of the pathway surface adjacent a groove emplaced pathway groove seal.

11. The pathway groove seal of claim 1, wherein the enclosure has a plurality of chambers within the enclosure and the illumination sources are positioned within one of the chambers.

12. A selectably illuminatable roadway groove seal for insertion into a roadway surface comprising:

a compressible, transparent elastomeric elongated enclosure having a first side and a second opposed side, wherein when the enclosure is emplaced in a groove in a roadway the first side of the enclosure sealingly abuts a first side of the groove and the second side of the enclosure sealingly abuts a second side of the groove;

a plurality of visible light sources positioned within the enclosure, wherein the light sources are positioned along the length of the enclosure and wherein the light sources are in communication with a remote power supply; and

a programmable controller in communication with the visible light sources, wherein the controller activates a first set of the light sources whenever a first set of conditions occur, whereby the activated light sources illuminate the roadway surface proximal to the activated light sources.

13. The selectably illuminatable roadway groove seal of claim 12, wherein the plurality of visible light sources include light sources that transmit more than one light color.

14. The selectably illuminatable roadway groove seal of claim 13, wherein the first set of light sources consist of light sources transmitting a single color of light.

15. The selectably illuminatable roadway groove seal of claim 12, wherein at least one of the light sources is attached to an interior surface of the enclosure.

16. The selectably illuminatable roadway groove seal of claim 12, wherein the enclosure incorporates a plurality of chambers.

17. The selectably illuminatable roadway groove seal of claim 16, wherein the light sources are positioned within an upper chamber facing the roadway surface.

18. The selectably illuminatable roadway groove seal of claim 12, further comprising a plurality of infrared transmitters.

19. The selectably illuminatable roadway groove seal of claim 18, wherein the programmable controller is in communication with the infrared transmitters and activates a set of the infrared transmitters upon the occurrence of a predetermined set of conditions.

20. The selectably illuminatable roadway groove seal of claim 12, wherein the light sources are LEDs or OLEDs.

21. A selectably illuminatable roadway groove seal for insertion into a roadway surface comprising:

an elastomeric elongated enclosure having a first side and a second opposed side, wherein when a length of the enclosure is emplaced in a groove formed in a roadway surface the first side of the enclosure sealingly abuts a first side of the groove and the second side of the enclosure sealingly abuts a second side of the groove; and

a plurality of infrared transmitters positioned within the enclosure, wherein the infrared transmitters illuminate a portion of the roadway surface;

whereby the portion of the roadway surface illuminated by the infrared transmitters is visualized by a vehicle equipped with an infrared sensor.
