1. A method comprising:
- receiving signals indicative of a location, the receiving by a first device coupled to an asset;
periodically sending a signal of operability between the first device and a second device, the second device coupled to the asset, and the second device configured to selectively disable the asset;
determining that receipt of the signal of operability has ceased; and
issuing an indication of the location of the first device responsive to the determining that receipt of the signal of operability has ceased, the issuing from the first device by a wireless transmission to a remote operations center.

Abstract
Remote tamper detection. At least some of the example embodiments are methods including: receiving signals indicative of a location, the receiving by a first device coupled to an asset; sending, at predetermined time intervals, a signal of operability between the first device and a second device, the second device coupled to the asset, and the second device configured to selectively disable the asset; determining that receipt of the signal of operability has ceased; and issuing an indication of the location of the first device responsive to the determining that receipt of the signal of operability has ceased, the issuing from the first device by a wireless transmission to a remote operations center.

9. A system comprising:
-
a first onboard device comprising; a first processor; a cellular network interface coupled to the first processor; a global positioning receiver coupled to the first processor; a first memory coupled to the first processor, the first memory storing a first program that, when executed by the first processor, causes the first processor to; receive signals indicative of a location of the first onboard device, the receipt by way of the global positioning receiver; receive periodic signals of operability from a second onboard device; determine the signals of operability have ceased to be received; and issue an indication of the location of the first onboard device over the cellular network interface to a remote operations center and responsive to the determination that the signals of operability have ceased to be received; the second onboard device comprising; a second processor; a second memory coupled to the second processor, the second memory storing a second program that, when executed by the second processor causes the second processor to; periodically issue the signals of operability to the first onboard device; and disable an asset. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
