Abstract
An apparatus and method of communicating in a tubular system ( ) through a media ( ) disposed therein and actuating a controllable device ( ) are disclosed. The apparatus and method utilize a transmission apparatus ( ) at a transmission node that is in communication with the media ( ). The transmission apparatus ( ) generates pressure impulses that are propagated through the media ( ). The pressure impulses may be either positive or negative pressure impulses depending upon the selected transmission apparatus. The pressure impulses are detected by a reception apparatus ( ) at a reception node. The detection apparatus may detect the pressure impulses as variation in the media ( ) or as variation in the tubular system ( ) caused by the pressure impulses. Once the detection apparatus ( ) has detected the appropriate pressure impulse or pattern of pressure impulses, a signal may be generated to actuate the controllable device ( ).
