     DETAILED DESCRIPTION 
     The present invention discloses a method, device, and computer program for mobile asset tracking. In one embodiment of the device, a pet tracking device is provided. It should be apparent to those skilled in the art that this embodiment may be extended to any other type of asset, and the methods and computer program claimed herein could likewise be extended. More particularly the device can be used for anything that can be tracked for example, but without limiting the application, pets, people, children, assets and the like. 
       FIG. 1  illustrates one embodiment of the tracking device  2 . In the embodiment shown in  FIG. 1  the tracking device acts as a pet tracking device comprising a housing  4  attachable to a pet collar (not shown). This may be provided by tooling four indentations  6  into the edges of the housing  4  to accommodate a belt or collar D-rings  8  at either end of the device and maintain air/water right seal. 
     The device may be permanently sealed by a waterproof shell. The shell may be made of a silicone based material or rubber based material, in either of which cases it would optimally display impact resistance and comfort to a pet to which it is attached. The silicone may also permit the device to be completely scaled and protected from air, water, scratches, dust, and other like elements that could otherwise harm the device. One type of material that can be used is sold under the trade-mark GORTEX. 
     In the embodiment of the device wherein it is a pet tracking device  2  for attachment to a pet collar, the device may be shaped such that its back edge  8  is an arc or concave. This will allow the device to be more comfortably worn by a pet. 
     There may also be provided means, such as a button  12 , for activating and deactivating the device  2 . A visual indicator  14 , such as an LED, may also be provided for indicating whether the device is currently activated or deactivated. The silicone or rubber casing may be made translucent over top of the LED to allow a person to see whether the LED is on or off. 
     The device may include a battery. The battery may be charged using a magnetic induction battery charging device. No internal components, including the battery, need to be accessible where the magnetic induction battery charging device, described below, is used. 
     There may also be provided on the device  2  a connection for the magnetic induction charging system. The operation of magnetic induction charging systems is known to those skilled in the art. A connection area may be provided on the device, such that it may pair or mate with the charger. The connection area may be flush with the surface of the device for aesthetic reasons or an indentation in the device for ease of mating with the charger. The connection area may be provided with the silicone or rubber protective coating, since a magnetic induction charging system does not typically require the connection to come into physical contact with the charger. 
     The device may include features enabling it to provide positional tracking capabilities, including a global positioning system (GPS) transceiver and an accelerometer to sense positional acceleration of the device. In the device of the present invention, a two or three axes accelerometer may be utilized to sense change in the three dimensional position of the device. Sensing of altitude may be optionally enabled. The position of the device is used for both the allowed device travel boundaries and for locating a lost asset. 
     The accelerometer can be used to indicate if a pet is located out of a Geofence which can indicate the pet is lost or stolen. Also the accelerometer can be used for insurance purposes in the event a fragile article such as glass is cracked and the accelerometer can determine where and when the article was exposed to an impact or acceleration. 
     The device may require an antenna wire for use with cellular systems and satellite systems. In this case, the antenna may be routed in the device, also sealed by the protective coating. 
       FIG. 2  illustrates a remote control  30  that may be provided for controlling the device  2 . The remote control  30  may have a display screen  32  for communicating messages to a user operating the device  2 . The display screen  32  may display text and/or graphics including providing the device&#39;s signal level, battery level, GPS activation status, and whether allowed device travel boundaries or Geofence are enabled. The allowed device travel boundaries are described more fully below. 
     The remote control  30  may also be provided with several input means. For example, the remote control  30  may have buttons corresponding to features, such as activating  34  and deactivating  36  the device  2 , querying the current device status  38  (which may result in the display screen displaying the status), and activating  40  and deactivating  42  the allowed device travel boundaries. A user may desire to deactivate the allowed device travel boundaries to permit the device to asset to travel freely. When a user activates the allowed device travel boundaries using the remote control  30 , the boundaries are set at a predetermined radius around the current location of the device. The current location of the device may be determined using the global positioning transceiver described below. 
     A Geofence is a virtual perimeter for a real world geographic area. Geofencing is a feature in a software program that uses the global positioning system (GPS) or radio frequency identification (RFID) to define geographical boundaries. A Geofence is a virtual boundary. 
     Geofence programs allow an administrator to set up triggers so when a device crosses a Geofence and enters or exits the boundaries defined by the administrator a small message signal (SMS) or email alert is sent. 
       FIG. 4  graphically illustrates an embodiment utilizing a Geofence. A customer can set a Geofence at their current location by pressing a button  42  on the device  30 . The button press initiates an immediate GPS location request and calculates the accuracy of this locate request. Once the locate and accuracy are calculated, the device establishes a Geofence around itself. The size of the Geofence is pre-determined by manufacture settings and multiplied by the accuracy variable. 
     For example: The device  2  is at 123 My Street, My City, USA (longitude: −111.899046 and latitude: 33.665489). The accuracy is calculated at 10 meters, so the device knows within 10 meters where it is located. If the manufacture setting is a 20 meter Geofence around any device, we would multiply a 20 meter Geofence by 10 meter accuracy variable and establish a 200 meter Geofence around the device. The accuracy variable must be incorporated into the equation to prevent false alerts. A false alert would occur if the device was not exactly where the initial located calculation was established, and an attempt to Geofence that specific plot on a map was requested. Even if the device had not moved, the device would send a false alert on the next scheduled locate request, indicating it was outside the original Geofence area. Having a larger Geofence area helps reduce the risk of this happening because it encompasses the surrounding areas inside an inaccurate locate request when the Geofence is being established. 
     The Geofence can be turned on  34  or off  36  at the device level. Holding button  40  will create a Geofence and notify the customer with the audio prompt “Geofence On”. Holding button  42  will end the Geofence setting and notify the customer with the audio prompt “Geofence Off”. 
     A Geofence is represented in the GUI by a translucent circle  49  or circle outline overlaid onto a geographical earth map.

     The remote control  30  may include a means to secure itself to a belt clip holster or collar clip holster. The remote control may include a battery, and may also be provided with a magnetic induction charging system and operable to mate to the charger that is also used with the device. 
     Messaging transceiver systems may be incorporated into both the remote control and the device to enable messaging between the two. One of several messaging protocols may be used, as known to those skilled in the art. Optimally, a low power messaging system is used for preserving battery life. 
     Several types of messages may be sent from the remote control to the device, including: activation and deactivation of the device; activation and deactivation of the allowed device travel boundaries. The device may return acknowledgement messages to the remote control, and the remote control may resend the requests if a transmission failure is experienced. 
     Several types of messages may be sent from the device to the remote control, including: confirmation of activation and deactivation of the device; confirmation of activation and deactivation of the allowed device travel boundaries; and various alerts such as low battery, out of range detection and inbound call. 
     Receipt of messages on the device  2  may be communicated to a user with the visual indicator  14  (such as LED). For example, when the device  2  is activated or deactivated, or the allowed device travel boundaries are activated or deactivated, the visual indicator  14  may provide feedback using preset series of timed blinked. Furthermore the visual indicator  14  may be configured to blink at set intervals while the device is activated so that the user may confirm that the device has not turned off. The visual indicator  14  may provide a quick series of blinks, each series separated at set intervals, to indicate the continued activation of the allowed device travel boundaries. The visual indicator  14  may provide yet another type of blinking activity while the device is charging. 
     Optionally, the device and remote control may also include an audio speaker and a microphone to enable voice communications between the device and remote control. Methods of transmitting voice communications wirelessly are known to those skilled in the art. Certain methods may include the addition of a dial-pad to the remote control, to initiate communication to the device. 
     Alternately, the remote control may be replaced with a personal digital assistant (PDA) that is operable to enable the various functions described above. 
       FIG. 3  illustrates a magnetic induction charging system charger for use with the device and remote control. The magnetic induction charging system may be any charger known to those skilled in the art. Magnetic induction charging uses magnetic induction to transfer power wirelessly from a charging base to a target device, which is typically enabled by incorporating an internal module into the device to accommodate magnetic induction charging system. 
     Optimally, the cradle portion ( 35 ) of the magnetic induction charging system is sized to comfortably fit the dimensions of the device and remote control, whichever is larger. Optimally, the device and remote control are of the same length and width, and the cradle ( 35 ) is slightly larger, to comfortably accommodate the device and remote control when charging. 
     Theft prevention may be included for the device. Event notification to the user may be provided if the device is removed, or is attempted to be removed, from the asset. Notification methods may include email, SMS, voice and/or fax, which may be configured using the user interface described below. Sensing of the device removal status may be enabled by several methods, including:
         1) Embedding a magnet into the device and another magnet in the attachment means to the asset. When the two are separated, owner notification is initiated.   2) Providing a set of transceivers in the device and attachment means. The transceivers regularly communicate. When the transceivers are spatially separated, a failure to communicate is experienced, which is assumed to mean the device has been removed from the attachment means.       

     A user interlace (UI) may be provided to the user. The UI may be provided as a computer program or an internet web application. 
     The UI may allow a user to register its communication means. This may include registration of a phone number, email address, facsimile number, SMS number, etc. for purposes of receiving alerts in connection with the present invention. 
     One of the features accessible through the UI may be locating the device and associated asset. The location may be communicated to the user by viewing a map  47  with an indication of the current location of the asset ( 49 ). There may be several types of locate methods, including: ms-based, ms-assisted, cost efficient, and control plane. The use of ms-based, ms-assisted, and control plane locate methods are known to those skilled in the art. A cost-efficient method may include a first locate attempt, using the ms-based method, and upon failure a ms-assisted second attempt. 
     The user interface may also allow for activating, deactivating, and configuring the allowed device travel boundaries. The configuration of the device travel boundaries may allow for configuring the radius of the boundaries  45 , which is described above. This configuration does not change the activation status. The central point of the allowed device travel boundaries may also be set using a post address  43 . Additionally, a user may set a future timeframe  41  during which the allowed device travel boundaries will be activated. 
     Optionally, the UI used in conjunction with the device may provide a social networking capability for users. This may allow users of the system that are within close proximity to meet each other. 
     To accomplish the social networking aspect of the present invention: a user obtains a device and registers the device with a central registration application, such as a website (more fully described below); the central registration application provides a means for the user to update the device and remote controller a label, such as a pet name or user name; when the pet owner comes within a certain range of another registered remote control, the two remote controls temporarily pair with each other to exchange a text message, such as “Hello my name is X”, introducing them to the other user. 
     Registration of the device with the central registration application may be comprised of several steps, including:
         1) The user enters the label and the identification number of the device (such as IP address) into the application. Once these two fields are populated, the application generates a message (such as SMS message) to the device with the label.   2) The device receives the message, and populates a pre-defined field within the device firmware. Once that field is populated, a message is sent from the device to the remote control. Any future changes to the label using the application will also generate a message to the device and subsequently the remote control.   3) The remote control receives message and populates a pre-defined field within the remote control. Once that field is populated the display means of the remote control displays the label.   4) Upon receipt of the label, the remote control updates its profile to allow pairing with other remote controls, which may be disabled by default. This allows the remote control to pair with another remote control. When pairing occurs, the label is sent to the other remote control and displayed on the display means of the other remote control.       

     Thus the users are alerted to each other&#39;s presence. 
     The device  2  has an internally mounted Temperature Sensor and related application firmware. The physical sensor monitors the temperature of the device. The device can send its temperature status information wirelessly over the public network (currently CDMA/Code Division Multiple Access) to a GUI (Graphical User Interlace). The device  2  may be configured from the manufacture to check its internal temperature at any diagnostic frequency (example 1 min or 1 hour or 1 day). It may also be configured by the manufacture to send the information wirelessly to the GUI on a predefined communication schedule. The diagnostic frequency and communication schedule do not have to be identical. 
     The device  2  can initiate an alert that is sent directly to the subscriber. The alert is sent from the device  2 , over the wireless network to the subscriber&#39;s pre-defined alert location. The subscriber may define and change what the alert methodology is through the GUI, which can include one or all of the following 1) an email 2) SMS (Short Message Service) 3) fax. The subscriber may also configure the specific address of the alert (examples: SMS=987.654.3210, email=subscriber@subscriber.com, fax=987.654.3210) from the GUI. 
     Defining the alert methodology and configuring the specific address of the alerts are facilitated through a GUI which is an ASP (Application Service Provider). 
     Temperature tolerances or thresholds may be defined by the subscriber through the GUI. Tolerance thresholds include a hot and cold setting. If either the hot or cold thresholds are exceeded (too hot or too cold), as they were entered into the GUI by the subscriber, an alert is sent to the subscriber the next time the device performs a self diagnostic. 
     Therefore in one application it is possible to determine if the animal is a potentially dangerous environment due to extreme temperature. In another application it is possible to determine if a perishable asset or other such as warehoused food is in an environment to be spoiled.
