Abstract

A system, apparatus and methods are described that wirelessly communicate with its environment in response to stimuli generated locally within a communication device or within a remote activation device.

Claims

1. A system for delineating a crosswalk across a street, the system comprising:

at least one wireless communication device, that may be secured to a surface on the street and at an edge of the crosswalk, that communicates information about the crosswalk in response to an activation stimulus; and

an activation device that transmits an activation command, over a wireless communication channel, to the at least one wireless communication device.

2. The system of claim 1 wherein the wireless communication device has at least one light emitter that visually identifies an edge of the crosswalk.

3. The system of claim 2 wherein the at least one light emitter comprises a light emitting diode.

4. The system of claim 1 wherein the wireless communication device has at least one audio component that audibly communicates information about the crosswalk.

5. The system of claim 1 wherein the wireless communication device comprises at least one sensor provides data so that a threshold event may be identified and, in response, the wireless communication device is activated.

6. The system of claim 5 wherein the sensor is a light intensity sensor that senses an intensity of daylight.

7. The system of claim 5 wherein the sensor is a time-of-day sensor that includes a clock.

8. The system of claim 1 wherein the wireless communication device comprises a rechargeable battery and photovoltaic cell.

9. The system of claim 1 further comprising a configuration device that configures the wireless communication device and activation device.

10. A wireless communication device that can be securely mounted on a surface, comprising:

a housing having at least one surface that can be secured to a surface;

an antenna that is configured to receive an activation command on a communication channel;

a communication component that provides information to a surrounding environment;

a rechargeable battery that provides power to at least one component in the wireless communication device; and

digital logic, within the housing, that processes data received on the communication channel.

11. The wireless communication device of claim 10 further comprising at least one sensor.

12. The wireless communication device of claim 11 wherein the sensor is a daylight sensor that detects an intensity of daylight.

13. The wireless communication device of claim 11 wherein the sensor is a time-of-day sensor comprising a clock.

14. The wireless communication device of claim 10 further comprising a photovoltaic cell that recharges the rechargeable battery.

15. The wireless communication device of claim 10 wherein the communication component comprises at least one light emitter.

16. The wireless communication device method of claim 15 wherein the at least one light emitter comprises a light emitting diode.

17. The wireless communication device of claim 10 wherein the communication component comprises an audio emitter.

18. The wireless communication device of claim 10 further comprising a memory unit that stores information recorded by the wireless communication device.

19. A method for activating a wireless communication device, the method comprising:

receiving a request to activate for at least one wireless communication device that is attached to a road;

generating an activation command for the at least one wireless communication device;

broadcasting the activation command for the at least one wireless communication device; and

activating the at least one wireless communication device.

20. The method of claim 19 wherein the at least one wireless communication device flashes lights after being activated.

21. The method of claim 20 wherein the lights on the at least one wireless communication device are synchronized.

22. The method of claim 19 wherein the at least one wireless communication device emits an audible signal after being activated.

23. A wireless communication device that can be securely mounted on a surface, comprising:

means for receiving an activation command on a communication channel;

means for providing information to a surrounding environment;

means for providing power to at least one component in the wireless communication device from a rechargeable batter; and

means for processing data received on the communication channel.

24. The wireless communication device of claim 23 further comprising means for sensing a threshold event after which the wireless communication device is activated.

25. The wireless communication device of claim 23 further comprising means for recharging the rechargeable battery.

26. The wireless communication device of claim 23 wherein the means for providing information comprises at least one light emitter.

27. The wireless communication device of claim 23 wherein the means for providing information comprises an audio emitter.

28. The wireless communication device of claim 23 further comprising means for storing information recorded by the wireless communication device.
