1. An apparatus for communicating information between an inside and an outside of a wall, comprising:

  • at least one outside ultrasonic transducer acoustically coupled to an outside surface of the wall for sending an ultrasonic carrier signal into the wall and for receiving a reflected output information containing ultrasonic signal from the wall;

    at least one inside ultrasonic transducer acoustically coupled to an inside surface of the wall for receiving the ultrasonic carrier signal and for generating and sending the reflected output information containing ultrasonic signal into the wall;

    a carrier generator connected to the at least one outside ultrasonic transducer for driving the at least one outside ultrasonic transducer to generate the ultrasonic carrier signal;

    detector means connected to the at least one outside ultrasonic transducer for detecting the reflected output information in the information containing ultrasonic signal; and

    sensor means connected to the at least one inside ultrasonic transducer for reading information on the inside of the wall and for supplying the information to the inside ultrasonic transducer for generating the reflected output information containing ultrasonic signal.
