Abstract

See full text

A method and device for controlling EM radiation from an exposed manhole around roadways. A remote field unit controller is disposed under a manhole cover proximal to a roadway, with a sensor attached to either the manhole cover, a manhole, or the remote field unit controller, providing information of at least one of a position, acceleration, direction of the manhole cover. An EM transmitter/receiver and EM emitter/absorber are disposed under the manhole cover and an EM controller communicates to the EM transmitter. When the sensor detects sufficient movement of the manhole cover, a signal is sent to the remote field unit controller to at least one of suppress, alter, and turn off EM emissions from the EM transmitter so as to prevent EM radiation from entering the roadway. The EM transmitter is at least one of a lidar, infrared, EM, and time-of-flight emitter or sensor.
