1. An apparatus comprising:

  • operational means for at times performing a function other than communication that consumes power at a first rate, and for at other times performing a communication function that consumes power at a second rate higher than the first rate;

    means for deriving electrical energy from radiant energy incident upon the apparatus;

    means for storing electrical energy, received from the means for deriving, sufficient so as to power the operational means at the first rate for the function other than communication;

    connection means for electrically connecting the operational means to an external source of power selectively during all such times as the operational means is performing the communication function;

    wiring means for constantly electrically connecting the operational means to the means for storing electrical energy;

    transportable power source means, electrically connected to the operational means by the connection means during all such times as the operational means is performing the communication function, for serving as the external source of power for powering the operational means at the relatively-higher second rate;

    wherein the powering of the operational means for the communication function by the transportable power source means permits that this communication function, which uses power at the relative-higher second rate, may transpire without substantial diminution of the energy stored in the means for storing energy.
