The present application discloses at least a method, apparatus, and system for automatic refueling of a driverless vehicle. A specific implementation of the method includes: sending refueling request information when a fuel amount is lower than a preset value and a refueling condition is satisfied; receiving preselected gas station information corresponding to the refueling request information; determining, from the preselected gas station information, destination gas station information and driving route information of a destination gas station; sending refueling request information after arriving at the destination gas station based on the driving route information of the destination gas station; turning off an engine and/or an electric motor after receiving refueling permission information corresponding to the refueling request information, opening a fuel tank cap, and sending refueling confirmation information; and closing the fuel tank cap after receiving refueling completion information. This implementation improves the refueling efficiency.

A system and method for fueling multiple saddle tanks of hydraulic fracturing equipment from a single cart. The cart having multiple retractable fuel lines for providing and obtaining fuel. Each retractable fuel supply line uses a flowmeter, a ball valve, and an electrically actuated valve to provide remote control to a controller based upon a user's selected fueling requirements. An electronic reporting system provides fuel data to operators and users. Fuel data such as fuel tank status, amount of fuel usage over a stage level, a daily level, or job level along with a fill level of the fuel tank.

An aircraft refueling system (10) includes a master controller (12), a fleet controller (14) in communication with the master controller, a platform controller (18) in communication with the fleet controller, and a fuel control system (16) in communication with the platform controller. Embodiments of an aircraft refueling system may include a primary pressure controller (20), a secondary pressure controller (22), a programmable logic controller (24), and a data logger controller (26). The master controller may be configured to receive and analyze data from at least one of the fleet controller, the platform controller, and the fuel control system; and to modify operational parameters or upgrade the fuel control system based at least in part on the analysis of received data.

Devices such as vehicles, remote sensors, and so forth consume energy during operation. Described herein are systems, devices, and methods for transferring energy from an uncrewed autonomous vehicle to a vehicle such as a car. The uncrewed autonomous vehicle may locate the vehicle at a rendezvous location, and connect with the vehicle while the vehicle moves. Once the uncrewed autonomous vehicle connects to the vehicle, the uncrewed autonomous vehicle may transfer the energy to the vehicle.

A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

A multiply-redundant system that protects fueling of rockets, aircraft and other vehicles using Liquefied Natural Gas (LNG) along with an oxidizer such as Liquefied Oxygen. One or more sensors in combination with one or more optional microswitches combine to detect any leaks, fire or explosion hazards quickly locking out further fueling. For different levels of safety, different combinations of sensors can be used.

An unmanned self-sustained fuel dispensing station for fuels of all sorts (gasoline, pesticides, water, fertilizers etc.) a tank, docking, and coupling system for unmanned aerial vehicles (UAV) of the vertical takeoff types. The station can be independent of public power and communication utilities and can operate by remote control without an on-site attendant. The preferred system has a central command center with a control computer in communication with a station control computer located at one or more satellite stations through a communications link. The station control computer can be controlled remotely by the command center. The station control computer programming has control over the activities of the station through an electrical generation subsystem with a solar array, battery bank, battery charger and standby generator; a fuel dispensing subsystem; a security subsystem with video cameras; a communications link and a status sensor subsystem.

A mobile fuel distribution station includes a mobile trailer, a pump, a manifold, hoses, detachably connectable fuel caps connected or connectable with the hoses, valves, and fuel level sensors. The station is configured to operate the pump responsive to a low fuel threshold to provide fuel to the manifold, from the manifold to the valves, and from the valves through the hoses. A related method includes receiving fuel operating parameter data from at least one mobile fuel distribution station into a remote server, determining whether the fuel operating parameter data is within a preset limit, and sending a control action in response to the fuel operating parameter data being outside the preset limit. A related system includes one or more of the stations, at least one server configured to receive fuel operating parameter data, and at least one electronic device configured to communicate with the server.

A fuel delivery system automatically selects one out of several available fuels for a vehicle having a specialized fuel filler neck. A dispenser pump assembly includes a pump base, a hose assembly and a nozzle assembly which includes a nozzle spout and a cylindrical collar member slidably mounted on the nozzle spout. A sensor on the nozzle assembly generates a signal, based on a position of the collar when the spout is fully inserted into a fuel filler neck of the vehicle. The signal is transmitted via wires, wireless signal, fiber-optic cables or other medium. An electronic controller in the pump base selects an appropriate fuel, based on the signal received from the sensor. If the available fuels include percentages of ethanol or other additives, a precision blending system ensures that the correct amount of additive is provided. Methods of selecting a fuel using the system hereof are also disclosed.

Various multifunctional dispensing systems with overhead fuel/air delivery and methods for using the same are provided. Such a system can include a dispenser system and an overhead delivery unit suspended on tracks above a vehicle drive aisle at a fueling station. The overhead delivery unit can include a fuel dispensing nozzle and an air dispensing nozzle that can be moved about the tracks so as to optimally position the nozzles to be approximately overhead the fuel doors and tires, respectively. Such an arrangement allows a customer to refuel their vehicle and inflate their tire(s) without moving their car between each transaction.
