First Claim
1. An onboard device comprising:
- a processor;
a memory coupled to the processor;
an analog-to-digital (A/D) converter coupled to the processor, the A/D converter has an analog input port and a reference voltage port;
a pair of wires, a first wire of the pair of wires coupled to the analog input port of the A/D converter, and a second wire of the pair of wires coupled to the reference voltage port of the A/D converter;
a cellular transceiver coupled to the processor;
a global positioning system (GPS) receiver coupled to the processor;
the memory stores a program that, when executed by the processor causes the processor to;
monitor, by way of the pair of wires and the A/D converter, voltage levels of a main battery of a vehicle for presence of a start sequence of an internal combustion engine of the vehicle;
detect movement of the vehicle based on satellite signals received by the GPS receiver; and
send a message to an operations center remote from the onboard device, the message indicating movement of the vehicle without occurrence of the start sequence, and the sending by the cellular transceiver.

Abstract
An onboard device comprising a processor, a memory coupled to the processor, and an analog-to-digital (A/D) converter. The onboard device also comprises a pair of wires where a first wire of the pair of wires is coupled to an analog input port of the A/D converter, and a second wire of the pair of wires is coupled to a reference voltage port of the A/D converter. The onboard device also comprises a cellular transceiver and a global positioning system (GPS) receiver. In some embodiments, the memory of the onboard device stores a program that, when executed causes the processor to monitor, by way of the pair of wires, voltage levels of a main battery of a vehicle for presence of a start sequence of a vehicle, detect movement of the vehicle, and send a message to an operations center indicating movement of the vehicle without occurrence of the start sequence.
