Ionization systems and methods include moving air into contact with one or more ion generators and then past an ozone removal assembly to remove at least some ozone from the air. The air may be moved by a fan and may be filtered before contacting the one or more ion generators. The amount of one or more of the following of the air may be measured: the amount of ions, particulates, temperature, humidity, and other relevant factors. The ionization amount may be adjusted based on one or more of the measured amounts. The one or more ion generators and ozone removal assembly may be constructed as part of a single unit so they can be removed and replaced easily.

A photocatalytic structure that can uniformize ultraviolet lights is provided. The photocatalytic structure includes a housing, a groove formed at a top of the housing, multiple grille slices being engaged with two sides of an inner wall of the groove, multiple grille passages being formed between every two adjacent grille slices, metal meshes disposed on both top and bottom of the grille slices, and a UVC-LED light board disposed at a side of the grille slices. The photocatalytic structure stacks the grille slices to form the grille passages. The UVC-LED light board makes grille passages to reflect the ultraviolet light. More uniform lights are formed at both upper and lower sides of the grille passages. The UVC-LED light board close to the metal meshes ensures the uniform lights to be emitted onto a gap plane with a smaller refraction angle. Therefore, everywhere on the metal meshes are fully illuminated.

The present disclosure relates to a telepresence system that enables better communication. The telepresence system includes: a network that connects a plurality of bases; and a plurality of telepresence apparatuses that transmit and receive video images and sound via the network, and share the video images and the audio between the respective bases. Further, in each of the telepresence apparatuses, a presentation device that performs presentation for prompting communication by users at different bases is disposed at the center of a shared communication space in which the users communicate with each other. The present technology can be applied to a telepresence system, for example.

Methods, devices and systems are described for digitally creating new scents or digitally dispensing gas, vapor, or liquid substances. A device includes a container or replaceable cartridge including one or more chambers containing one or more scented substances; a housing structured to include a compartment to hold the cartridge, an opening to allow the one or more scented or unscented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to deliver a scented substance from the corresponding chamber to the opening for delivering a scent from the one or more scented substances; and an actuator switch arranged in a corresponding transporting channel and rapidly operable to move between an open position and closed position based on an applied signal to selectively allow passage of the scented or unscented substance from the corresponding transporting path.

Ozone converters containing differing ozone converting materials are provided into air aircraft airflow management systems, with the ozone converter positioned in an air management architecture at positions configured to assist replacement, and maintenance, and with the ozone converters further positioned downstream of air conditioning packs, and with the ozone converters configured to reduce at least one of ozone concentrations and volatile organic compound concentrations from airflows directed to passenger cabin air volumes and flight deck air volumes.
