Patent ID: 8508349

Claim:
An onboard device comprising: a processor mechanically coupled to an asset; a global positioning system (GPS) module communicatively coupled to the processor, the GPS module configured to receive position data from GPS satellites; a computer-readable storage medium communicatively coupled to the processor, the storage medium storing instructions that, when executed by the processor, cause the processor to: responsive to a trigger event, activate a geo-fence boundary for the asset, wherein activating the geo-fence boundary comprises: reading data indicative of a current location of the asset from the GPS module; defining a geo-fence boundary surrounding the asset based on the current location of the asset; and activating the geo-fence boundary; and subsequent to activating the geo-fence boundary, monitor asset location with respect to the geo-fence boundary, wherein monitoring asset location with respect to the geo-fence boundary comprises reading data indicative of successive positions of the asset from the GPS module.
