  • a sensor adapted to receive a message provided by a user;

    an analog-to-digital (A-D) converter coupled to said sensor, said A-D converter being operative to output a digital signal dependent on said message provided by said user;

    a memory operative to store data;

    a control circuit coupled to said memory and to said A-D converter, said control circuit operative to access said memory; and

    a transmitter coupled to said control circuit, said transmitter operative to transmit an electromagnetic signal;

    wherein said circuit is operative to store said digital signal in said memory; and

    wherein said circuit is further operative to transmit an electromagnetic signal dependent on said stored digital signal when directly initiated by said user, said user directly initiating transmission of the electromagnetic signal after said digital signal is stored, said user thus having an opportunity to review said message before transmission.
