A method for capturing CO.sub.2 from a gas stream using a metal organic framework (MOF) based physisorbent CO.sub.2 concentrator is provided. In the method, MOF material is pretreated, a gas stream is then introduced into the CO.sub.2 concentrator which comprises the pretreated MOF material. CO.sub.2 from the gas stream is captured with the CO.sub.2 concentrator to generate a CO.sub.2-free stream, which is discharged the from the CO.sub.2 concentrator into the atmosphere. Introduction of the gas stream into the CO.sub.2 concentrator is stopped when the pretreated MOF material becomes saturated with CO.sub.2. The CO.sub.2 concentrator with the saturated MOF material is then regenerated by introducing hot air, hot nitrogen, vacuum, or a combination thereof into the CO.sub.2 concentrator thereby generating a CO.sub.2-rich stream. The CO.sub.2-rich stream is diverted for purification and the regenerated CO.sub.2 concentrator is recycled for future capture of CO.sub.2.

Methods and apparatus for a desiccant saturation monitoring system having a body with a first portion configured to hold a desiccant material and a second portion configured to position a sensor in relation to the desiccant material. A light source can irradiate the desiccant material and the sensor can detect irradiance from the desiccant material for at least one wavelength to determine saturation information for the desiccant material.

Methods and systems are presented for diagnosing a breach of an evaporative emissions system. The methods and systems include repurposing a resonator as a vacuum reservoir to reduce a pressure of an evaporative emissions system so that it may be determined if there is or is not a breach of the evaporative emissions system.

The present invention addresses to a device that allows the control of the gas pressure at the outlet of a fixed bed adsorption equipment operated at high pressures, by means of the actuation of a micrometric valve (6), wherein the valve must be located downstream of the equipment. The valve actuation takes place by means of a stepper motor (1), controlled by a microcontroller board (22), which connects to the valve shaft by means of a system of pulleys (2, 5) and belt (3). The present invention is applied in adsorption units, in which other gases are present, by altering the tuning parameters of the PID controller or even being used in a liquid medium or gas-liquid two-phase flow.

A bypass for an air dryer having an inlet, a prefiltration stage having a drain valve to purge contaminants, a pair of inlet valves in communication with the prefiltration stage to control the flow of compressed air through the desiccant towers, and an outlet coupled to the pair of desiccant towers. The bypass may be a bypass valve that is normally open to the outlet when the air dryer is unpowered and pilotable to be a closed to allow air to flow to the prefiltration stage when the air dryer is powered. The bypass may be a three-way valve that is normally coupled to the outlet and that may be piloted to connect to the prefiltration stage when the dryer is powered. The bypass may also be a check valve that opens in response to pressure in the inlet to allow compressed air to flow directly to the outlet.

A ventilator includes a bidirectional breath detection airline and a flow outlet airline. The flow outlet airline includes an airline outlet. The flow outlet airline is configured to be connected to an invasive ventilator circuit or a noninvasive ventilator circuit. The breath detection airline includes airline inlet. The airline inlet is separated from the airline outlet of the flow outlet airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The pressure sensor is configured to measure breathing pressure from the user and generate sensor data indicative of breathing by the user. The ventilator further includes a controller in electronic communication with the pressure sensor. The controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor.

An air pollution prevention device applied for a baby carriage includes a sealing cover, a filtration cleaner, a gas detection module and an intelligent control and process device. The sealing cover is hooded on the baby carriage for forming a sealed space. The filtration cleaner penetrates the sealing cover form the outside of the baby carriage for introducing an outside air into the sealed space of the baby carriage and discharging an air pollution source out of the sealed space. The gas detection module detects the air pollution source and outputs gas detection data. The intelligent control and process device receives and compares the gas detection data and controls an enablement of a gas guider of the filtration cleaner for filtering and exchanging the air pollution source in the sealed space so as to generate a clean air.

A method for operating a fuel cell system is provided. The method includes controlling a provision of fuel to the fuel cell system operating in a steady-state mode. The catalyst sensor is operated by providing a portion of the fuel and anode exhaust generated by the system to the catalyst sensor. Further, a change in an outlet temperature of the catalyst sensor is detected. Thereafter, it is determined whether a reformation catalyst of the catalyst sensor is poisoned by contaminants in the fuel based on the detected change in the outlet temperature.
