Abstract

Object tracking is facilitated. In accordance with one or more embodiments, an object tracking apparatus (200) includes a proximate-range circuit (212), a positioning circuit (214) and a communications circuit (216). The proximate-range circuit wirelessly verifies the identity and presence of at least one proximate-range communications device (220), and the positioning circuit determines positioning information of the object tracking apparatus. The communications circuit receives outputs from the proximate-range circuit and positioning circuit respectively regarding the verification and positioning information, and wirelessly communicates data to a remote communications station based upon the received outputs (140).

Claims

a proximate-range circuit configured to wirelessly communicate with at least one proximate-range communications device to verify identification and presence thereof, and to provide an output indicative of the identification and presence of the at least one proximate-range communications device;

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

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.

2. The apparatus of claim 1, wherein the communications circuit is configured to wirelessly communicate data via the distal-range communications station according to at least one of

communicating data based upon the received outputs by communicating positioning information corresponding to the output from the position-assessment circuit, in response to the output from the proximate-range circuit being indicative of a failure to verify at least one of the presence and identification of the at least one proximate-range communications device,

wirelessly communicating data indicating theft of an object connected to the object tracking apparatus, based upon the output of the proximate-range circuit indicating a lack of presence of a proximate-range communications device also connected to the object, and

wirelessly communicating data indicating removal of an object connected to the object tracking apparatus from a predefined area, based upon the output of the proximate-range circuit indicating the lack of presence of one of the at least one proximate-range communications devices that is located in the predefined area.

3. The apparatus of claim 1, wherein the proximate-range circuit is configured to provide an output indicative of both the presence and identification of the at least one proximate-range communications device.

4. The apparatus of claim 1, wherein the proximate-range circuit is configured to wirelessly communicate with at least one proximate-range communications device to verify the identification and presence of the at least one proximate-range communications device on a repeated cycle and to provide an output indicating that the at least one proximate-range communications device is no longer proximally located in response to failing to detect the presence of the at least one proximate-range communications device at one of the repeated cycles.

5. The apparatus of claim 1, wherein

the object tracking apparatus includes a memory circuit configured to store data corresponding to a device identification of one of the at least one proximate-range communications devices, and

the communications circuit is configured to wirelessly communicate the stored data to a user via the remote communications station for the device identification.

6. The apparatus of claim 1, wherein the object tracking apparatus is configured to generate and communicate an output to disable a vehicle to which the object tracking apparatus is connected, in response to at least one of

the output of the proximate-range circuit indicating that the at least one proximate-range communications device is no longer within communications range in response to failing to detect the presence of the at least one proximate-range communications device,

the output of the position-assessment circuit indicating a change in position of the vehicle, and

the communications circuit failing to register with a network via the distal-range communications station.

7. The apparatus of claim 1, wherein the object tracking apparatus is configured to respond to a user input by authenticating the user input and, in response thereto, deactivating at least one of the respective generation of the outputs and the wireless communication of data to the distal-range communications station.

8. The apparatus of claim 1, wherein

the proximate-range circuit is configured to provide an output indicative of the presence of the at least one proximate-range communications device by providing an output indicative of the removal of the object tracking apparatus from a predefined area, based upon the output of the proximate-range circuit indicating the lack of presence of one of the at least one proximate-range communications devices that is located in the predefined area, and

the positioning circuit is configured to initiate a tracking mode and determine the positioning information of the object tracking apparatus in response to the output of the proximate-range circuit indicating that the object tracking apparatus has left the predefined area.

9. The apparatus of claim 1, wherein the positioning circuit includes at least one of

the communications circuit, wherein the communications circuit is configured to detect a position of the object-tracking apparatus based upon signals received via the distal-range communications station over a common wireless link via which communications are effected, and

a global positioning circuit configured to receive signals from global positioning satellites and to detect a position based upon the received global positioning signals.

10. A system for tracking an object, the system comprising:
