The system may comprise an air treatment assembly having an indoor air inlet configured to receive indoor airflow directly from a room, a regenerable adsorbent material configured to adsorb at least one gaseous contaminant contained in the indoor airflow, at least one airflow element for directing the indoor airflow to flow through the air treatment assembly, an indoor air outlet for expelling the indoor air, from the air treatment assembly back into the room, a purge air inlet configured to receive and direct purge air over and/or through the adsorbent material for removal of at least a portion of the at least one gaseous contaminant, and a purge air outlet for expelling the purge air out of the air treatment assembly.

Embodiments of gas concentrating systems and methods are provided. These systems and methods comprise configuration of hardware and software components to monitor various sensors associated the systems and methods of concentrating gas as described herein. These hardware and software components are further configured to utilize information obtained from sensors throughout the system to perform certain data analysis tasks. Through analysis, the system may, for example, calculate a time to failure for one or more system components, generate alarms to warn a user of pending component failure, modify system settings to improve functionality in differing environmental conditions, modify system operation to conserve energy, and/or determine optimal setting configurations based on sensor feedback.

The present application concerns a mobile filter device configured for cleaning a gas and/or fluid stream, comprising a coupling platform provided, in the top surface, with an inlet and outlet for repeatable coupling to a corresponding inlet and outlet of the mobile filter device, and provided, in the side surface, with an inlet and outlet for coupling to a corresponding inlet and outlet of an industrial installation.

Disclosed herein a technique for producing a gas mixture for controlling an oxygen concentration in the interior of a container while reducing the overall weight of the apparatus. For this purpose, a gas mixture supply device is provided for a container refrigeration apparatus. The gas mixture supply device is provided with adsorption columns. If one of the first and second adsorption columns is supplied with air, the adsorption columns are pressurized, and nitrogen in the air is adsorbed onto an adsorbent. If air is sucked from the other of the first and second adsorption columns, the adsorption columns are depressurized, and nitrogen adsorbed onto the adsorbent is desorbed. A gas mixture including the nitrogen desorbed from the adsorbent is supplied to the interior of a container.

A device and a system that delivers continuous positive airway pressure in conjunction with oxygen delivery is disclosed. The system is portable so that patients may be mobile and conveniently travel. Several means are disclosed for integrating oxygen production into a positive airway pressure (PAP) device, including oxygen production machinery entirely integrated into the PAP housing, oxygen production machinery that mates with a PAP device but which may operate independently, and where portions of the oxygen production machinery are located in the PAP housing and other portions (for example, the compressor) are located in a separate module, such as, for example, an AC-to-DC power conversion module.

The invention discloses a method for adsorbing ethylene gas using amorphous granular starch. The method firstly prepares amorphous granular starch, wherein starch slurry is prepared from starch with a ethanol aqueous solution and NaOH solution is added dropwise so as to react at 30 to 35 C. for 20 to 50 minutes; Then the slurry is centrifuged, neutralized with an ethanol hydrochloride solution, washed and dried to obtain the amorphous granular starch. The amorphous granular starch is placed in a high-pressure reactor and ethylene gas is introduced after the reactor is vacuumized to react at 0.8 to 1.5 Mpa and 20 to 30 C. for 15 to 25 h so that starch powder product adsorbing with ethylene is obtained. The test result shows that the content of ethylene in the obtained product can reach more than 30%. The method is simple, highly efficient and cheap for the adsorption process of ethylene, and the product is expected to be widely applied in the field of fruit and vegetable modified atmosphere preservation.

Disclosed is a skin care device using plasma. The skin care device may include a first plasma generating device; and a main body configured to supply power to the first plasma generating device and to control the first plasma generating device based on an input from a user.

A dynamic air intake (A, A) for vehicle, helmet or safety clothing and the like, including a rigid casing (1, 5; 1, 5) having an air inlet opening (A1, A1), an air outlet opening (A2, A2) and a closed channel (1.4, 1.5, 3, 5; 1, 1.4, 25, 3, 5) for the passage of an air flow passing between said inlet opening (A1, A1) and said outlet opening (A2, A2), comprising air/water filter separation means including at least one layer (3, 3) of material which absorbs rainwater and/or nebulised water, water vapour, arranged along said channel (1.4. 1.5, 3, 5; 1, 1.4, 25, 3, 5), without obstructing the cross section of the same channel, in direct contact with said passing air flow and in which water and water vapour, which are transported by said passing air flow, are gradually collected and released to be dispersed towards the outside of said rigid casing.

A circulation chamber for a cargo container comprises a cargo container extension including a housing, a cargo container aperture, and an interior volume; the cargo container extension is structured and dimensioned to be attached to an opening of the cargo container, thereby placing the interior volume in fluid communication with an interior of the cargo container. The housing, cargo container aperture, and interior volume may be cooperatively structured and dimensioned to allow at least a portion of the cargo container to be disposed in sealing engagement with the cargo container aperture, and furthermore, allow, at least partially, a door of the cargo container to be open while the circulation chamber is attached to the cargo container.

A controlled atmosphere system for a cargo storage space, the system comprising a separation area for receiving atmospheric gas from the cargo storage space, a gas moving device arranged to move atmospheric gas from the cargo storage space into the separation area to thereby increase a pressure within the separation area, and a molecular sieve arranged in communication with the separation area, such that when the separation area is at an overpressure, selected molecules are vented out of the separation area through the molecular sieve.
