A fuel distribution station for land vehicles includes a first fuel tank assembly for releasably holding fuel and a second fuel tank assembly for releasably holding fuel. A control system selectively permits and monitors a discharge of fuel from both of the first and second fuel tank assemblies. An operation platform is elevated a predetermined distance above ground by support legs and is formed by rigidly connecting the first fuel tank assembly to the second fuel tank assembly.

A method of controlling a fuel pump includes receiving a first set of data characterizing an audible activation word including a first voice pattern. Control of the fuel pump is authorized in response to the first voice pattern matching a stored voice pattern within a database. A second set of data characterizing an audible command word is received, where the audible command word includes a second voice pattern. The fuel pump is controlled based on the audible command word in response to the second voice pattern matching the stored voice pattern within the database.

Implementations are described for maintaining helium/air mixture within a tube in an evacuated tube transportation system. A first implementation includes a set of helium tanks uniformly fitted along the tube length, where helium is injected with controlled valves that open or close to maintain the desired level of helium. An operations control center (OCC) receives helium concentration levels in the tube and instructs a controller in the tube to release helium into the tube when detected levels of helium is lower than the desired level of helium. Another implementation is described where a capsule traversing the tube may have a source of helium gas that can be released into the tube. A hybrid approach is also described where helium can be released from a source within the tube and from another source within the capsule.

Fuel dispensers, systems and methods are provided for electronically transmitting data characterizing fueling transactions in a fueling environment, and in particular from a fuel dispenser. In an exemplary embodiment, a fuel dispenser is provided having a printer module that can perform operations that enable any one or more of replacing a printer, providing a user with a printed transaction record at a remote location, and/or provide the user with an electronic transaction record. The application of the printer module can facilitate providing a user with a printed and/or electronic transaction record, while minimizing, or eliminating, changes to standard communication protocol associated with components of a payment terminal that can deliver formatted transaction data to a typical printer. Minimizing or eliminating changes to standard communication protocol associated with providing users with transaction records can facilitate retrofitting the printer module to existing fuel dispensers, and/or simplify design considerations for new dispenser.

The present application provides a method, device and system for automatically fueling a vehicle. The method includes: judging, by a fueling control device of the vehicle, whether the vehicle needs to be filled with fuel; obtaining driving route information and vehicle status information of the vehicle in the case of determining that the vehicle needs to be filled with fuel; determining fuel amount to be filled according to the driving route information and the vehicle status information of the vehicle; sending a fueling request to a fueling management system; receiving a feedback message from the fueling management system, wherein the feedback message includes position information of a fueling device; and prompting the vehicle to obtain fuel offered by the fueling device indicated by the position information of the fueling device according to the fuel amount to be filled.
