1. An object tracking apparatus comprising:

  • a proximate-range circuit configured to wirelessly communicate with at least one proximate-range communications device;

    wherein at start-up of the object tracking apparatus, the proximate-range communications device is present and the proximate-range circuit enters a wait mode;

    wherein in the proximate-range circuit remains in the wait mode if the proximate-range communications device is re-verified as present;

    wherein in the proximate-range circuit enters a tracking mode if the proximate-range communications device is not present;

    wherein in the proximate-range circuit provides an output indicative of an identification and the present or not present presence of the at least one proximate-range communications device;

    a position-assessment circuit configured and arranged to assess current position information of the object tracking apparatus using received wireless communications, and to provide an output indicative of the position information;

    a communications circuit coupled to receive the outputs from the proximate-range circuit and the position-assessment circuit, and configured to wirelessly communicate data including the position information via a distal-range communications station based upon the received outputs; and

    wherein in the communications circuit repeatedly transmits the current position to the distal-range communications station when the proximate-range circuit is in the tracking mode.
