Abstract: A method and a gateway system of a mobile asset are described. A voltage produced by a power system of the mobile asset is monitored by a gateway system. In response to determining that a first fluctuation occurs in the voltage produced by the power system of the mobile asset over a first interval of time, the gateway system operates in a first mode. In response to determining that a value of the voltage produced by the power system of the mobile asset is less than a voltage threshold, the gateway system automatically transitions to operating in a second mode, which is different from the first mode and causes the gateway system to consume less power than when it is operating in the first mode.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a device arrangement to derive unknown portions of a communication data scheme. A proxy node is established in a communication path between two nodes configured to transmit communications according to a communication bus standard. The communication data included in the communications transmitted between the nodes conforms to a communication data scheme. The proxy node logs communications transmitted between the nodes via the communication path, resulting in a communication log. The communication log can then be used to derive unknown portion of the communication data scheme, such as commands for requesting specified data types and the data format for transmitting data of specified data types.

Abstract: Systems, methods, and non-transitory computer-readable media for a remote vehicle immobilizer. A network gateway device receives a command from a remote computing device to modify a configuration of an electronic switch from a first configuration to a second configuration. The electronic switch is positioned in a conducting path between a starter motor of the vehicle and a battery of the vehicle. In response to receiving the command, the network gateway device transmits a signal to the electronic switch via a two-way communication channel connecting the network gateway device to the electronic switch. The signal causes the electronic switch to modify the configuration of the electronic switch from the first configuration to the second configuration.

Abstract: A method is disclosed that includes the step of: responsive to determining, based on input data, that a gateway system is receiving power from a power source of a mobile asset and the mobile asset is not in-use, transitioning the gateway system from a first mode to a second mode, wherein transitioning comprises turning on a functionality of the gateway system that is turned off when the gateway system is operating in the first mode.
