1. A method comprising:
- tracking location of an asset by an onboard device mechanically coupled to the asset, the onboard device electrically coupled to a source of power of the asset, and the onboard device receiving power from the asset;
charging a supercapacitor coupled to the onboard device; and
thendetecting a complete loss of power provided to the onboard device, the loss of power indicative of tampering with the onboard device, and the detecting by the onboard device; and
after the complete loss of power sending a message by wireless transmission, the sending based on power derived from the supercapacitor, the message indicative of tampering with the onboard device, and the message including an indication of a last known voltage provided by the asset prior to the complete loss of power, and the sending by the onboard device during the complete loss of power.

11. A system comprising:
an onboard device configured to couple to an asset, the onboard device comprising; a processor; a wireless interface coupled to the processor; a global positioning receiver coupled to the processor; a supercapacitor coupled to the processor; a memory coupled to the processor, the memory storing a program that, when executed by the processor, causes the processor to; charge the supercapacitor with power from the asset during a period of time when the onboard device is receiving power from the asset; receive signals indicative of a location of the onboard device; detect a complete power loss to the onboard device; and
thenissue an alert, the issuing by a wireless transmission powered by the supercapacitor, the alert including an indication of a last known voltage provided by the asset prior to the complete power loss. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
