The present invention provides an apparatus for producing medical foam for wound care or hair stimulation. The apparatus includes a foam generation unit having a fluid reservoir, a fluid delivery line and a foam generation tip. The apparatus also includes a compressed gas unit having at least one container of compressed gas, a source of electric power, and a gas regulator valve. A supply of wound care or hair stimulating solution is communicably connected to the foam generation tip such that when the apparatus is operated medical foam is produced by the foam generator tip.

A fuel cell vehicle includes a fuel cell, a fuel storage container, a container installation space, a fill lid box, and a fuel gas detector. The fuel cell is to generate power through an electrochemical reaction between a fuel gas and an oxidant gas. At least part of the fuel storage container is disposed in the container installation space. The fill lid box includes a gas fill port inside the fill lid box and has a communication hole to connect an inside of the fill lid box with the container installation space. The fuel gas is to be supplied through the gas fill port into the fuel storage container from an outside of the fuel cell vehicle. The fuel gas detector is disposed inside the fill lid box to detect a fuel gas leakage and to detect a fuel gas density in the container installation space.

A valve integrated pressure regulator (VIPR) device that can be attached to the outlet of a gas cylinder, which can monitor the amount of gas in the cylinder is provided. Features of the disclosed device include an electronic control, electronic alarm and the electronic display that are powered by rechargeable battery that may be disposed within the VIPR shroud or within a removable cylinder base affixed to a bottom of the gas cylinder. Additional functionality and security features may be provided via additional internally disposed sensors and/or wireless or hard-wired communications with one or more auxiliary devices.

A multi-stage gas compression, storage and distribution system utilizing a hydrocarbon gas from a municipal gaseous supply line in a manner that does not affect an operational integrity of said municipal gaseous supply line includes an inlet line fluidly in fluid communication with a supply of hydrocarbon gas at a first pressure, a first compression unit configured to compress the hydrocarbon gas from the inlet line to a second pressure, a first storage vessel configured to receive the hydrocarbon gas from the first compression unit for storage at the second pressure, a second compression unit configured to compress the hydrocarbon gas from the first storage vessel to a third pressure, and a second storage vessel configured to receive the hydrocarbon gas from the second compression unit for storage at the third pressure.

Systems and methods for dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.

A replaceable cartridge for storing a fluid includes a pressure vessel for holding the fluid; a connecting line extending from the pressure vessel to a first connection surface on an external side of the cartridge; and a valve system comprising a first shut-off member disposed in the connecting line; wherein the connecting line has a taper in a direction of the first connection surface.

Systems and methods for controlling the temperature and pressure of a cryogenic liquid methane storage unit are provided. The disclosed systems and methods generate methane gas from a reservoir of liquid methane stored within the methane storage unit, vent the methane gas through one or more outlet valves connected to the methane storage unit, and generate electric power using the vented methane gas. The generated electric power can then be used to initiating a cooling cycle, which reduces the temperature of said reservoir of liquid methane and reduces the pressure in said methane storage unit. Micro anaerobic digesters and methane storage units may be configured in a networked environment with a central controller that monitors remote units.

A compressed pressure vessel suitable for serving as construction element for building energy storage constructions thereof is described. The compressed pressure vessel comprises a first, inner, segment, wherein the inner segment comprises an inlet for filling or emptying the inner segment and wherein the inner segment is suitable for storing hydrogen, and a second, outer, segment, the outer segment adapted for being filled with a fluid, different from hydrogen, wherein the outer segment is substantially fully encompassing the inner segment.

System and method for digitally monitoring a pressure vessel for holding compressed gas, wherein the system comprises a sensor unit placeable on the pressure vessel for gathering information regarding the condition of the pressure vessel, a communication unit for wirelessly communicating the gathered information to a receiver wherein the sensor unit comprises a temperature sensor for measuring the temperature of the pressure vessel, a gas pressure sensor, at least one power unit for supplying power to the sensors and the communication unit.

The invention relates to a pressurized gas container, in particular a gas cylinder, having an internal volume for gas storage, a fluid-distributing valve, a pressure sensor and microprocessor-based control means. The microprocessor-based control means are configured to detect filling of the gas container with gas, by comparing said at least one pressure value measured by the pressure sensor with at least one predefined and stored reference pressure threshold value; then to initiate a timer on the basis of a detection of filling of the gas container with gas; and to trigger a warning when the timer exceeds a given period calculated from the initiation of the timer.
