  • Publication number: 20060039698
    Abstract: The present invention comprises a system and method for communicating with a traffic signal by which at least one communication controller and integrated light controller are coupled by a high frequency (“HF”) coupler to a power line for transmission. In each of the directions of communication, specific transmission methods and data protocols are used over the communication link. The communication link protocol used for communication between the integrated light controller and the communication controller provides a robust method for framing data within a message structure that provides byte-by-byte synchronization and message integrity through a parity check per byte, and a checksum calculation.

  • Publication number: 20050099319
    Abstract: A traffic signal light having high technology sensors sensing a plurality of conditions proximate the traffic signal light. The sensors may include an acoustic detector, a radiation control monitor, a chemical biological mass spectrometer, a gas detector and an accelerometer. The present invention finds technical advantages in that these high technology sensors can be discreetly sealed in a traffic light housing cavity and hidden from public view, while providing increased security in geographical locations having control signal lights. These high technology sensors may also be disposed outside the traffic light housing cavity.
