The present invention relates to a reusable food storage container designed to store food items while preventing the odor of stored food from being retained in the container material. The container has a base comprised of odor-resistant material, such as stainless steel or glass, and has a lid with an embedded replaceable charcoal filter. The charcoal filter is configured to absorb odor emanating from stored food items. The container can comprise different sizes, designs, shapes, and colors and can be washed and reused. In one embodiment, a lid of the container has a cavity for embedding the charcoal filter, and in another embodiment, the bottom surface of the lid has a frame with a continuous channel for accommodating the charcoal filter. The lid is configured to seal the stored food material using a skirt wall for preserving the food items.

An oxygen concentrator includes one or more adsorbent sieve beds operable to remove nitrogen from air to produce concentrated oxygen gas at respective outlets thereof, a product tank fluidly coupled to the respective outlets of the sieve bed(s), a compressor operable to pressurize ambient air, one or more sieve bed flow paths from the compressor to respective inlets of the sieve bed(s), a bypass flow path from the compressor to the product tank that bypasses the sieve bed(s), and a valve unit operable to selectively allow flow of pressurized ambient air from the compressor along the one or more sieve bed flow paths and along the bypass flow path in response to a control signal. The valve unit may be controlled in response to a command issued by a ventilator based on a calculated or estimated total flow of gas and entrained air or % FiO.sub.2 of a patient.

According to the present invention there is provided a device and method for atmospheric water harvesting operative in an alternating sequence of an absorption phase and a desorption phase. The device comprises an air permeable adsorbent substrate being subject to an atmospheric airflow during the absorption phase and being subject to a circulated airflow during the desorption phase. The device further comprises a liquid heated heat radiation element embedded in the adsorbent substrate and a heated liquid heating media being circulated in the heat radiation element during the desorption phase. The device may further comprise air shutters, where the direction of the atmospheric airflow being substantially transversal to the direction of the circulated airflow. The air shutters are capable of blocking an entrance and an exit of the atmospheric airflow during the desorption phase.

An indicator is provided in a vehicle for indicating necessity of change of a fuel vapor absorber in a venting line of a vehicle tank, especially a methanol tank for fuel cell vehicles.

Provided is a particle capturing system and a particle capturing system capable of capturing even small particles to be captured in a gas phase.

The particle capturing system according to the present technology includes: an acoustic aggregation device that aggregates particles to be captured in a gas phase by applying sound waves to the particles to be captured; and an aggregate capturing device that charges particle aggregates obtained by aggregating the particles to be captured in the gas phase and captures the particle aggregates with an electrostatic force.

An air purifier (100) includes a housing (400) formed with an air duct (401), an ozone generation device (20), an activated carbon purification unit (80), and a fan (200) arranged in the air duct (401). The air duct (401) includes an air inlet (402) and an air outlet (403). The air outlet (403) is disposed indoors. The ozone generation device (20) and the activated carbon purification unit (80) are arranged in the air duct (401) along the direction of the air inlet to the air outlet (403), and the ozone generation device (20) is used to generate ozone. The fan (200) is used to suck gas from the air inlet (402) during operation and let the gas pass through the ozone generation device (20) and the activated carbon purification unit (80) to be discharged from the air outlet (403) into the room.

A coated substrate (2a, 2b) adapted for hydrocarbon adsorption having at least one surface, and a coating on the at least one surface, the coating comprising particulate carbon and a binder, wherein the particulate carbon has a BET surface area of at least about 1300 m.sup.2/g; and at least one of: (i) a butane affinity of greater than 60% at 5% butane; (ii) a butane affinity of greater than 35% at 0.5% butane; (iii) a micropore volume greater than about 0.2 ml/g and a mesopore volume greater than about 0.5 ml/g. A bleed emission scrubber (1) and an evaporative emission control canister system (30) comprising the coated substrate (2a, 2b) are provided. They can control evaporative hydrocarbon emissions and may provide low diurnal breathing loss (DBL) emissions even under a low purge condition.

A CO.sub.2 recovery system used in a vehicle includes a CO.sub.2 recovery device recovering CO.sub.2 contained in inflowing gas; and a flow rate control device controlling flow rates of gases present in a plurality of different regions of the vehicle flowing into the CO.sub.2 recovery device. The gases present at the plurality of different regions include at least any two among air at an outside of the vehicle, air at an inside of the vehicle, and exhaust gas discharged from a body of an internal combustion engine of the vehicle.

Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. The organic matter processing apparatus includes a lid assembly that is positioned at the top or head of the processing apparatus and an air treatment system. The lid assembly is operative to open to allow a user to deposit organic matter into the processing apparatus or to remove a removable bucket contained therein. The lid assembly is operative to close and provide an odor containing seal that prevents or substantially mitigates escape of odor. The air treatment system uniformly distributes untreated air through an air treatment chamber to convert the untreated air to treated air, which is exhausted out of the processing apparatus.

A filter includes a filter outer wall, and a filter inner wall spaced apart from the filter outer wall. The filter inner wall and the filter outer wall define a filter void therebetween, and the filter inner wall and the filter outer wall extend along a filter axis. A volume of filtration material is positioned in the filter void, and a plurality of baffles extend between the filter inner wall and the filter outer wall. The plurality of baffles are configured to induce a helical component to an airflow entering the filter void at a first void end relative to the filter axis and exiting the filter void at a second void end opposite the first void end.
