The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

An aircraft including a supply system including a hydrogen gas tank, a recipient device that consumes hydrogen gas, a feed line between the tank and the recipient device, a first enclosure in which are installed a heating system configured to heat the hydrogen gas, a second enclosure in which are installed a drive system configured to drive the hydrogen gas towards the recipient device, a safety tank for a pressurized inert fluid, and a purge line between a free section of the feed line and a distribution system. If a leak is detected, the pressurized inert fluid is pushed into the purge line to evacuate the hydrogen gas from the free section. With such a supply system, the hydrogen gas present in a free section is evacuated in case of leakage.

An automatic gas shutoff system for protecting the occupants of a home, apartment, RV, vehicle, etc. from dangerous levels of carbon monoxide. The automatic gas shutoff system generally includes one or more carbon monoxide detectors, a control unit, and a gas shutoff valve under the control of the control unit, so that the gas supply to a malfunctioning appliance can be shut off in the event it is creating dangerous levels of carbon monoxide within a protected space. The shutoff valve may have a manual reset feature that requires a problem condition to be repaired before the valve is manually reset to allow normal gas flow to resume.

Methods, apparatus, systems, and articles of manufacture are disclosed for managing a hydrogen storage and distribution system. An example apparatus disclosed herein includes an apparatus comprising memory and one or more processors to execute instructions to detect, via hydrogen concentration data, an elevated hydrogen concentration at a hydrogen storage system, determine a mass flow rate of a leak associated with the elevated hydrogen concentration based on the hydrogen concentration data and a location of a sensor associated with the hydrogen concentration data, and mitigate the leak by sending a signal to one or more controllable features of the hydrogen storage system based on the determined mass flow rate.

The present invention relates to a breathing air charger for detecting a tank state, capable of providing air properly adjusted in the concentration of oxygen and nitrogen to a breathing air tank used by a firefighter or a scuba diver, and of effectively discharging air from the breathing air tank.

According to at least one aspect, a hydrogen gas dispensing system is provided. The hydrogen gas dispensing system includes a source configured to provide a hydrogen gas, a storage device configured to store the hydrogen gas up to a first pressure level, a dispenser configured to dispense the hydrogen gas up to a second pressure level that is higher than the first pressure level, and a compressor configured to compress the hydrogen gas from the source up to the first pressure level for storage in the storage device and configured to compress the hydrogen gas from the storage device up to the second pressure level for dispensing via the dispenser. According to at least one aspect, the dispensing system comprises an input power port configured to receive input power and an output power port configured to deliver output power derived from the input power to charge an electric vehicle.

The present application discloses a system and method for supplying acetylene, the system having at least one acetylene storage apparatus, a detection module, a gas dilution module and a gas supply regulating module. By mixing a feedstock stream outputted from the acetylene storage apparatus with a diluting gas in a specific ratio, a photoionization detector is successfully used to detect a solvent content in the feedstock stream. This real-time and continuous detection method ensures a stable supply of acetylene to a downstream process.

A method for coordinating an evaporation process of hydrogen from a hydrogen tank of a motor vehicle by an assistance system includes initiating the evaporation process of hydrogen from the hydrogen tank of the motor vehicle into an area surrounding the motor vehicle by an electronic computing device of the assistance system in accordance with a hydrogen pressure in the hydrogen tank. Evaporation information regarding an additional motor vehicle having an additional hydrogen tank is received by a communication device of the assistance system. The evaporation process of hydrogen from the hydrogen tank of the motor vehicle is coordinated in accordance with the evaporation information regarding the additional motor vehicle.

An apparatus for transferring gas to a gas vessel is provided. The apparatus includes a radio frequency identification (RFID) reader configured to interrogate an RFID tag associated with the gas vessel for RFID information. The apparatus includes a gas input port configured to be in removably connected to gas supply, a gas output port configured to be removably connected to the gas vessel and a processor configured to: determine at least one gas vessel characteristic associated with the RFID information, control a flow of gas from the gas input port to the gas output port based at least in part on the at least one gas vessel characteristic, determine at least one filling criterion based at least in part on the RFID information, determine whether the at least one filling criterion is met, and trigger at least one action if the at least one filling criterion is not met.

Dual level sensing, vacuum monitoring, smart supply cylinders, smart oxygen monitors, and real time data collection functionality are integrated with a cryogenic storage system to improve sample safety and user safety. The dual level sensing system includes two liquid nitrogen level sensors installed into a cryogenic freezer that send redundant level information to a controller. Vacuum monitoring is performed via a gauge, installed on a vacuum port, that communicates data to the controller. The controller further receives level information from supply cylinders and oxygen levels from one or more oxygen monitors. The aforementioned data sources can be integrated into control decisions executed by the controller. In addition, all operational data of the cryogenic storage system is communicated to a cloud-based platform to provide real-time status monitoring, trend analysis, and alarm notifications.
