METHODS AND SYSTEMS RELATED TO REMOTE POWER LOSS DETECTION
First Claim
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
detecting a complete loss of power provided to the onboard device, the detecting by the onboard device; and
after the complete loss of powersending a message by wireless transmission from the onboard device, the sending based on power derived from the supercapacitor, and the message including an indication of a last known voltage provide by the asset prior to the complete loss of power.

Abstract
Remote power loss detection. At least some of the example embodiments are methods including: 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 then detecting a complete loss of power provided to 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, and the message including an indication of a last known voltage provide by the asset prior to the complete loss of power, and the sending by the onboard device after the complete loss of power.

13. 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 position 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; 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 (14, 15, 16, 17, 18, 19, 20, 21, 22)
