  • the contents of US Patent Application Serial No. 12/215,462 are incorporated herein by reference in its entirety.
  • the fob is made relatively small, and may have the size of a car key fob, for example.
  • the fob wirelessly communicates over a relatively short range with an asset tracking device, or asset tracker, that is attached to an asset, such as a vehicle (car, truck, motorcycle, boat) or ship container, for example.
  • asset tracking device such as a vehicle (car, truck, motorcycle, boat) or ship container, for example.
  • Each fob has a unique ID that the asset tracker uses to identify an authorized user.
  • the asset tracker may be programmed to recognize multiple fobs (IDs), and multiple fobs may be paired with multiple asset trackers, so that multiple users of multiple vehicles, for example, can interface with multiple asset trackers.
  • the asset tracker has a short-range wireless communication interface for communicating with the fob(s), and a satellite communication interface for transmitting simplex (one-way) messages by way of a satellite to a remote location (network). Alerts regarding asset movement and I/O activity along with messages transmitted from the fob(s) by way of the asset tracker that are received at the remote location (network) are forwarded to a customer who owns or is responsible for the asset or is to receive messages from the user carrying the fob.
  • the asset tracker may be configured to have a terrestrial wireless network interface, such as cellular interface, to allow communication with the remote location (network) if satellite communication is unavailable.
  • the user carrying the fob thus has personal tracking functions in a small device as long as the fob is in range of the asset tracker.
  • Alerts and messages transmitted from the fob are relayed by the asset tracker over the satellite link to the network and ultimately to the desired contact.
  • Alerts include emergency messages and tracking messages, for example. If the fob is not in range of the asset tracker, and the asset is moving, the asset tracker can sense this, and it transmits its location to the network and desired contact along with an "unauthorized movement" message that indicates that it could be stolen.
  • Each fob may be configured to have user-specific functions depending upon the asset to which the asset tracker is attached. Thus, alerts may be transmitted by the asset tracker if the asset travels at an unauthorized speed or to an unauthorized location, for example (i.e., geo-fence). Each alert may include transmit time, location, and fob ID, for example.
  • the asset tracker is configured to transmit GPS location data to the network if it is in motion and an authorized fob is not substantially collocated with it.
  • Software at the remote location may be configured to process the GPS location data to determine speed and direction of motion of the asset or determine if there is rapid deceleration, indicating a possible accident, or such determinations can be made locally at the asset tracker . Results of this determination may be transmitted to appropriate authorities or to the designated customer.
  • the asset tracker may be utilized in fixed locations, such as on a race track or at specific locations in a building, for example.
  • the fob ID is identified by the asset tracker and reported to the remote site to indicate presence of the fob at that location. This insures that the person or vehicle with the fob has reached a particular location, such as a location along a race track, or a guard passing by a check point in the building.
  • sensors may be attached to the asset tracker to monitor opening of doors or windows of a vehicle or building, for example.
  • the asset tracker may be used in other security applications.
  • asset trackers may be placed at strategic locations on a campus, with each student carrying a uniquely-identified fob. Student locations may be identified and tracked as fobs pass by each of the asset tracker locations.
  • the fobs would allow the SPOT personal tracking functions to be used by students, including transmission of 911 emergency and help messages to relevant campus emergency service personnel.
  • the disclosed apparatus (SpotOnTM) and methods provide for an asset tracking GPS device (asset tracker) and a key fob that wirelessly communicates with the asset tracking device.
  • the asset tracking device is mounted to an asset (car, boat, other vehicle or equipment). Alert and tracking information is sent from the asset tracker to a remote network via simplex communication using a satellite. Alerts of asset movement and I/O activity are then sent to the customer.
