A gas supply system for providing high pressure (HP) gas to a low pressure (LP) gas destination, having a primary HP gas unit and a reserve HP gas unit, which provide regulated lower-pressure gas to a supply manifold, and an LP destination regulator that provides an LP regulated gas supply to a consumption subsystem. A one-way flow valve in fluid communication from the primary HP gas unit to the reserve HP gas unit, ensures that the reserve HP gas unit remains substantially full, even after numerous cycles of depletion and replacement of the primary HP gas unit, during which the HP supply is provided by the reserve HP gas unit, which helps to avoid the risk that the reserve tank pressure and supply might mistakenly, unexpectedly or unintentionally be depleted

A gas cylinder monitoring system is disclosed having a gas cylinder for receiving and distributing gas contained therein, a first monitoring system associated with the gas cylinder operable to monitor data associated with the gas cylinder and having a transmitter operable to broadcast the data at a controlled time and/or time interval in a discrete advertisement package, and a second monitoring system associated with one or more locations in which the first monitoring system may reside and having a receiver operable in a first mode to receive the advertisement package broadcast from the first monitoring system when the second monitoring system is within range of the first monitoring system.

A design and construction method for a Collapsible Cryogenic Storage Vessel can be used for storing cryogenic liquids. The vessel provides the ability to be packed for transport in a compact state and erected at the point of use. The vessel can be used multiple times. The vessel's volume can also be adjusted during use to minimize or eliminate head space in the vessel.

A cryogenic energy storage system comprises at least one cryogenic fluid storage tank having an output; a primary conduit through which a stream of cryogenic fluid may flow from the output of the fluid storage tank to an exhaust; a pump within the primary conduit downstream of the output of the tank for pressurising the cryogenic fluid stream; evaporative means within the primary conduit downstream of the pump for vaporising the pressurised cryogenic fluid stream; at least one expansion stage within the primary conduit downstream of the evaporative means for expanding the vaporised cryogenic fluid stream and for extracting work therefrom; a secondary conduit configured to divert at least a portion of the cryogenic fluid stream from the primary conduit and reintroduce it to the fluid storage tank; and pressure control means within the secondary conduit for controlling the flow of the diverted cryogenic fluid stream and thereby controlling the pressure within the tank. The secondary conduit is coupled to the primary conduit downstream of one or more of the at least one expansion stages.

A method for calculating the autonomy of a gas distribution system assembly including a container containing gas and equipped with at least one gas filling indicator device and a gas flow rate indicator device at the output of the container. The method includes recovering at least one item of identification information on the container and/or the gas used. The method also includes acquiring at least one image to recover a first datum on a value indicated by the gas filling indicator device and a second datum on a value indicated by the flow rate indicator device. The method also includes communicating the at least one acquired image and the at least one recovered tern of identification to a computation module configured to deduce therefrom a corresponding value of autonomy of the gas distribution assembly, the computation module including at least the ability to process images.

A modular shipping system includes a bulk shipping space; and a base to support a pair of stackable cryogenic shipping subunits positioned in the bulk shipping space during long distance shipment, each subunit having a plurality of feet on a subunit bottom adapted to rest above a plurality of corresponding foot receptacles on a subunit lid, each subunit having its own cryogen connection source to maintain temperature during transit.

Method, system, apparatus, and/or device for monitoring a shipment. The vapor plug system includes a vapor plug. The vapor plug fits onto a shipper and partially seals contents within a payload area of a shipper. The vapor plug system includes a sensor that is configured to measure or determine a condition or location of the shipper. The vapor plug system includes an electronic device that has a display. The display is configured to provide the condition or the location to a user. The vapor plug system includes a vapor plug adapter. The vapor plug adapter includes a recessed pocket that is configured to receive the electronic device. The vapor plug adapter includes an opening within the recessed pocket and is configured to receive the sensor and allow the sensor to be inserted into the payload area of the shipper.

Method and apparatus for real-time detection of the level of the cryogenic liquid in a container. The cryogenic liquid level detection apparatus includes a liquid level indicator, a floating scale, and a buoy attached at a bottom end of the floating scale. A top end of the floating scale moves against calibrated markings of the liquid level indicator, thereby indicating the level of the cryogenic liquid in real-time.

The disclosure includes a compressed gas tank locking device that can include an elongate housing. The elongate housing may include a closed end and an open end located opposite the closed end. The elongate housing may further include a sidewall extending between the closed end and the open end, a first aperture extending through the sidewall, and a second aperture extending through the sidewall. The second aperture may be located opposite the first aperture.
