摘要: An improved system and method for the automated refilling of cryogenic helium is provided. In one embodiment, the system includes a dewar in fluid communication with a liquid helium cryostat through a cryogen transfer line. A controller regulates operation of a three-way valve to pre-cool the transfer line and to cause gaseous helium to flow to the dewar and force liquid helium through the transfer line into the cryostat. The controller is coupled to the output of a cryogenic level sensor, such that the controller regulates the helium liquid level within the cryostat. During filling cycles, the dewar liquid level is also monitored by the cryogenic level sensor and an alarm sounds if the dewar liquid level is undesirably low. Between filling cycles, the controller is operable to ventilate the dewar through a solenoid vent valve in fixed time intervals to ensure the dewar pressure is sufficiently low so as to not bleed liquid helium into the cryostat.

摘要: An inflatable structure for gas storage includes an inner bladder containing a gas for storage and an outer wall spaced from the inner bladder. An intermediate space between the bladder and the outer wall is pressurized with a gas (such as air) other than the storage gas so that the structure is protected from environmental conditions such as wind and snow loading. The bladder and outer wall may be flexible fabric membranes and may be provided with lightweight support frames. The structures may be combined in a network of like structures for large scale storage.

摘要: A power management system and method including a normally-open switch, an on/off circuit, a microprocessor, and at least one sensor to monitor a condition. The on/off circuit includes an on/off control gate-controlled switch device such as a PMOS device for system power, a flip/flop switch to respectively activate and deactivate the on/off control PMOS device, and a transition detection circuit connected to the normally-open switch. A single DC power source establishes a source voltage to power the on/off circuit and the normally-open switch. The transition detection circuit generates an “on” signal when the user initially activates the normally-open switch, and supplies the “on” signal to the flip/flop switch to change it to an “on” state to activate the on/off control PMOS device. While activated, the on/off control PMOS device enables system power from the power source to be provided to at least the sensor and the microprocessor. The microprocessor generates an “off” signal when the normally-open switch is activated for at least a selected period of time, and supplies the “off” signal to the flip/flop switch to change it to an “off” state to deactivate the on/off control PMOS device and thereby disable system power to at least the sensor and the microprocessor.

摘要: When a calibration starting condition of a pressure sensor is satisfied while a fuel cell vehicle is traveling, the fuel cell vehicle starts to travel by using electric power supplied from a secondary battery. In the fuel cell vehicle, a pressure sensor is calibrated based on hydrogen pressure in a hydrogen gas flow channel downstream of a pressure reducing valve after a shut-off valve of a hydrogen tank is closed, and the hydrogen in a hydrogen gas flow channel is exhausted until hydrogen pressure upstream of the pressure reducing valve and hydrogen pressure downstream of the pressure reducing valve become substantially equal to each other. The fuel cell vehicle travels by using electric power supplied from the secondary battery while the pressure sensor is being calibrated, so that calibration processing of the pressure sensor can be performed without causing a noise.

摘要: An intelligent pressure management system that controls the pressure inside a cryogenic tank between variable target vapor pressure values and/or ranges that are set as a function of system operating conditions, by actuating an actively controllable valve disposed on a gaseous fluid vapor conduit; and in some embodiments, additionally by actuating an actively controllable valve on a liquefied gaseous fluid conduit, based on a signal received from a pressure sensor that measures the pressure inside the pressurized tank. The variable target vapor pressure values and/or ranges are determined as a function of at least two system operating conditions which can include the vapor volume in the storage space; the fluid flow demanded by the use device; and a measured temperature parameter that correlates to the temperature of the fluid exiting a heater.
