A dispenser interface module connects with an existing main processing board of a fuel dispenser via an existing data port of the main board and via a current loop communication link connection of the main board. The dispenser interface module determines an idle condition of the dispenser from analysis of signals on the link, without disturbing the signals on the link, and only performs actions such as reboot or software update of the main board, or retrieval of data from the main board through the data port, during the idle condition. The dispenser interface module may compress data retrieved through the data port by removing previously retrieved records from the retrieved data. The dispenser interface module instructs a communication module to wirelessly transmit the compressed data to a remote server for analysis. The communication module wirelessly receives, and forwards to the dispenser interface module, reboot or update messages and instructions.

A fueling adapter configured to permit a fuel dispenser which terminates in a twist lock mating assembly to be used to supply fuel to a fuel tank which has a fuel receiver outfitted with a dry break connector connected thereto, said fueling adapter comprising a dry break assembly rotatably connected to a twist lock assembly via a rotational connector.

A Reduced Boil-off Thermal Conditioning System (RBTC System) for transferring liquid natural gas (LNG) from a LNG supply tank to a LNG storage tank with reduced boil-off is disclosed. The RBTC System includes the LNG storage tank, a cryogenic fluid tank within the LNG supply tank, and a compressor. The LNG storage tank includes a first and second LNG pipe. The cryogenic fluid tank is configured to store a cryogenic fluid within the cryogenic fluid tank and the first and second LNG pipe are in fluid communication with to the cryogenic fluid tank. The first LNG pipe is in fluid communication with compressor.

An object is to suppress excessive insertion of a fueling nozzle during fueling. A nozzle guide configured to form a nozzle guide path that guides a fueling nozzle is placed inside of a filler neck main body configured to include a fuel passage that introduces a fuel supplied from the fueling nozzle toward a fuel tank. This nozzle guide comprises a first projection for nozzle restriction provided on a nozzle guide end opening portion at an end of the nozzle guide path along a nozzle guide direction and protruded from an end opening circumferential wall of the nozzle guide end opening portion to narrow at least part of a diameter of the nozzle guide path; and a second projection for nozzle restriction provided on a downstream side of the first projection along the nozzle guide direction and protruded from the end opening circumferential wall to narrow at least part of the diameter of the nozzle guide path.

A volatile liquid refueling apparatus, which includes a probe, and a receiver including a dual locking mechanism whereby said apparatus can be locked in either an open position or a closed position, and a safety lock which disables or enables access to the dual locking mechanism when manually.

Hydrocarbon condensate detection and control. The hydrocarbon condensate detection and control system includes detecting hydrocarbon in an aqueous mixture and controlling the flow of the aqueous mixture based on the hydrocarbon content of the aqueous mixture.

An improved fluid transfer accuracy, information collection, and overall management. A system may utilize a pump to transfer fluid from a source to a target vessel, a meter for measuring an amount of fluid transferred, a density meter to detect actual fluid density, and a control unit to determine actual fluid transfer amount based on density. As an example, a fluid flow meter can be coupled with a flow conduit to determine fluid volume, along with the density meter to detect real-time density of transferred fluid. During a fluid transfer event, such as aircraft refueling, LPG fueling, or other refined fuels or valuable liquids, fluid volume can be converted to fluid weight in real-time based on actual density. The real-time fluid weight can be used to determine if a target fluid weight has been reached, and fluid flow can be shut off at the appropriate time.

A vehicle control device for a vehicle includes a communication unit configured to communicate with a communication device located at a gas station, and a processor configured to control the vehicle to perform at least one of autonomous driving or autonomous fueling based on information received from the communication device. In addition, a control method for controlling a vehicle includes communicating with a communication device located at a gas station, and controlling a vehicle to perform an operation based on information received from the communication device.

A machine for replacing used transmission or power steering fluid in a vehicle with new transmission or power steering fluid includes a frame having a housing. The machine includes a pair of service hoses that extend from the machine and connect to the vehicle for placing the machine in the fluid flow. New, used, and axillary fluid tanks are provided. A pump and a manifold are associated with two of the tanks. The pumps provide for the selective withdraw or insertion of fluid into or out of the tanks. A display on the housing presents an operator of the machine with various tasks or options the machine can perform. A processor controls activation of the pumps and other electrical components based on inputs received by the display. Scales are provided under one or more of the tanks for determining the amount of fluid going into and out of the tanks during the exchange process.

A counter mountable fluid dispenser includes a below deck assembly and an above deck assembly. The below deck assembly includes a reservoir for storing a fluid, a dispensing mechanism in fluid communication with the reservoir, and a controller in circuit communication with the dispensing mechanism for operation of the dispensing mechanism. The above deck assembly includes a spout defining an outlet port in fluid communication with the reservoir for dispensing fluid stored in the reservoir upon operation of the dispensing mechanism, an external supply port in fluid communication with the reservoir by a supply passage to supply fluid to the reservoir, an access door movable between a closed position blocking access to the external supply port and an open position permitting access to the external supply port, and a switch mechanism configured to disable the dispensing mechanism when the access door is in the open position.
