  • (a) a source of power;

    (b) a transceiver assembly connect to said source of power said transceiver being adapted to transmit and receive electromagnetic radiation;

    (c) at least one sensor for being operatively connected to said structure for sensing a change in a selected condition of said structure, said sensor having a first element for being connected to a first part of said structure and a second element which is connected to a second part of said structure and which moves relative to said first element as a result of the change in said selected condition, said sensor being operatively connected to said transceiver for receiving said electromagnetic radiation and for returning said electromagnetic radiation to said transceiver, said returned radiation being indicative of said change in said selected condition of said structure; and

    (d) a transmitter operatively connected to said transceiver for transmitting an electromagnetic signal to a remote location which is in response to said electromagnetic radiation returned to said transceiver from said sensor.
