An aroma diffuser device for diffusing selected scents into the airspace of interior habitable spaces is disclosed. The disclosed device includes multiple diffusers for diffusing multiple scents into a fan-induced airstream. Two, three or more diffusers can be included in and/or upon the device.

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 method and a system for generating a fragrance (also referred to herein as perfume) are disclosed. A method may comprise providing a perfume blender machine (100) and cartridges (102) for storing liquid olfactory ingredients (112), the machine comprising dispensing means to dispense olfactory ingredients (112) from the cartridges (102) for generating a fragrance (114); controlling the dispensing means to generate a fragrance (114) based on instructions given by a user on the liquid olfactory ingredients (112) to be blended and the quantity of each; and generating a recipe with the information of the ingredients (112) and their respective quantities which have been used to generate the fragrance.

The invention relates to automated devices for pro¬ducing aerosols of liquid disinfectants and for spraying same. A mo¬bile hygiene unit comprises a housing (1) containing a disinfectant spraying unit (2) with a spraying nozzle (3), a tank (4) containing disinfectant, a compressor (5), and a control unit (6). It further com¬prises a mechanism for regulating the droplet size distribution of the aerosol, including a pump (7), an electromagnetic valve (8), and a dosing nozzle (9) with an internal cylinder. The disinfectant spraying unit (2) comprises a shaped nozzle (3) having a nozzle head (10) of axisymmetric cross-section attached thereto, and a mixing chamber (11) for mixing disinfectant with compressed air, having two thread¬ed inlets for a pneumatic line (12) and a hydraulic line (13), said inlets being arranged at an angle of 180°. The dosing nozzle (9) contains an internal cylinder and a rod with a threaded tip. The mobile hygiene unit generates an aerosol in four droplet size distribution modes: dry fog (from 3.5 to 10 pm), wet fog (from 10 to 30 pm), mist (from 30 to 50 pm), and spray (from 50 to 100 pm). The invention allows highly precise regulation of the droplet size distribution of the aerosol in each mode without the need to change the spraying nozzle.

A light fixture is provided to be disposed within a room and operable to provide visible light for the room and air disinfection via application of UV light to air flowing through an air treatment chamber. In one embodiment, one or more baffles may be disposed within the air chamber to substantially prevent UV light from leaking past the one or more baffles into the room. In one embodiment, a UV light regulator may be provided to selectively control an amount of UV light directed into the room.

A system for sterilizing biological material comprising beam generation circuitry for generating a radiating wave having radiating energy therein at a predetermined frequency therein. A controller controls the radiating wave generation at the predetermined frequency. The predetermined frequency equals a resonance frequency of a particular biological material and is determined responsive to a plurality of parameters from an influenza virus. The predetermined frequency induces a mechanical resonance vibration at the resonance frequency of the particular biological material within the particular biological material for destroying a capsid of the particular biological material. Radiating circuitry projects the radiating wave on a predetermined location to destroy the particular biological material at the predetermined location.

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.

A vehicular sanitization control device includes a rechargeable internal power source, a deep ultraviolet light source, a first display light source configured to display an operating state of the deep ultraviolet light source, a second display light source configured to display a state of charge of the internal power source, and a control unit configured to control a power supplied to the deep ultraviolet light source, a charging operation of the internal power source, and displays of the first display light source and the second display light source, respectively.

A system includes a plurality of carbon dioxide sensors each located in one of a plurality of spaces in a building and a plurality of air purification systems each located in one of the plurality of spaces and each including a UVC light source arranged within an internal space of a purification chamber and adapted to irradiate the internal space with UVC, an airflow system arranged to introduce environmental air from outside of the air purification system into the internal space of the purification chamber and expel purified air from the purification chamber back outside of the air purification system wherein each of the plurality of air purification systems is operable to purify air in response to an indication that an associated carbon dioxide sensor has sensed a level of carbon dioxide in excess of a predetermined threshold.

An air enhancing device (1) for disseminating molecules and/or other substances into the air is disclosed comprising a base frame (5) configured to be fixedly mounted in a wall, panel, or furniture of a human accessible space, in particular in an in-wall box or an in-wall cavity in a wall of a building; a cartridge holder (7) attached to the base frame (5) and configured to receive a removable cartridge, the cartridge being designed to contain a fluid substance; and a fan and/or microblower configured to draw air into the air enhancing device (1) and expel air containing at least a portion of the substance out of the air enhancing device (1) into the human accessible space; and/or an emission module attached to the base frame (5) in fluid communication with the cartridge and configured to distribute a portion of the fluid substance into the air.
