An ozone treatment device includes an ozone destruct module and an ozone generator mounted within a housing. The ozone destruct module and the ozone generator are mounted between corresponding air inlets and air outlets formed in the housing. The ozone treatment device also includes a controller mounted to the housing. The controller is configured to generate ozone with the ozone generator for a first time period and to automatically destruct ozone with the ozone destruct module for a second time period following the first time period. In certain implementations the treatment device includes an input device for receiving an operator input. In such cases the controller can determine the first and second time periods based on the operator input.

A method for sterilizing viruses comprises generating a beam having radiating energy therein at a predetermined frequency for generating mechanical eigen-vibrations in a spherical virus to destroy the spherical virus and a predetermined cartesian beam intensity for imparting transverse shear forces to an icosahedral lattice structure of the spherical virus to destroy the icosahedral lattice structure of the spherical virus using beam generation circuitry. A resonance frequency of the spherical virus for inducing the mechanical eigen-vibrations in the spherical virus is determined based upon a size, geometry, and protein material of the spherical virus using a predetermined three-dimensional acoustical model of mechanical vibrations within the spherical virus. The beam generation at the predetermined frequency and the predetermined cartesian beam intensity is controlled using a controller responsive to the determined resonance frequency. The predetermined frequency equals the resonance frequency of the spherical virus. The beam on is radiated a predetermined area to destroy the spherical virus at the predetermined area using radiating circuitry. The mechanical eigen-vibrations at the resonance frequency of the spherical virus determined by the predetermined three-dimensional acoustical model are induced within the spherical virus to destroy the spherical virus responsive to the predetermined frequency. The transverse shear forces are imparted to the icosahedral lattice structure of the spherical virus to destroy the icosahedral lattice structure of the spherical virus.

The invention is an air and surface disinfection robot designed to autonomously move through incredibly narrow spaces, specific to mass transportation vehicles such as aircraft, trains, busses, or ferries. The robot includes modes to operate in the spaces associated with transportation, such as waiting areas, bathrooms and narrow entry and exit ways.

In the transportation industry, turn around time (the time between two planned trips), is often incredibly short. Existing designs do not allow for a fast enough loading, setup and run time. This invention has been designed to optimize the portability, maneuverability, connectivity (data) and ease of use from other devices designed to disinfect such vehicles.

The invention uses UVC (germicidal) lamps, a proven technology for disinfecting pathogens. The design has been optimized by using a unique open cage design, so the light will transmit from all directions with minimal absorption to components on the device. This in combination with the lamp pattern and the robotics results in a very precise UVC light emission required for adequate, consistent disinfection of the surfaces and the air of mass transportation vehicles.

Finally, the invention consists of real time data streaming and remote operation as data is published through a connected cloud service and then onto the subscribed users.

In some aspects, an air purification system for a vacuum cleaner comprises an ultraviolet (UV) light unit disposed in a first location within the vacuum cleaner along an airflow pathway, configured to emit UV light at air containing particles including dust, dirt, and microbes while the air containing the particles is flowing in the airflow pathway where the UV light unit is disposed; and a particle filter unit disposed in a second location within the vacuum cleaner along the airflow pathway, the particle filter unit comprising one or both of a high-efficiency particulate air (HEPA) filter and an active carbon filter.

In order to guarantee reliable maintenance, a reliable energy supply and simple handling of the service cover and the vehicle air conditioner at the smallest possible structural cost, it is proposed that the service cover has electrical means, by means of which an air-treatment device arranged within the vehicle air conditioner can be supplied with the electrical energy necessary in order to operate said air-treatment device from outside the vehicle air conditioner.

The light system further includes a fan configured to generate an airflow and an airflow circuit configured to direct the airflow out of the main body of the lighting assembly. The light system also includes a tilt detection unit configured to detect a tilt angle of the lighting assembly and to generate a control signal to cause a speed of the airflow generated by the fan to change based at least on a detected change in the tilt angle of the lighting assembly.

Example techniques described herein involve a scent diffusing system. The system can include scent diffusing device(s), playback device(s), and controller device(s). The controller device may display on a graphical interface a representation of a first scent diffusing device and receive one or more inputs selecting the representation of the first scent diffusing device and a particular scent for the first scent diffusing device to release. At least one setting for the particular scent may be displayed which may include a scent release time. A selection of the at least one setting may be received, and the controller device may send a message to the first scent diffusing device including information indicating the scent to release and the selected at least one setting. The controller device can cause the first scent diffusing device to release the particular scent at the release time.

The present invention discloses a novel multipurpose fast dehumidification device, in which materials with different functions can be placed simultaneously or separately, such as moisture absorption materials, aromatic materials, mosquito repelling (insect repelling) materials or deodorization materials. The present invention comprises a base, a placement frame and a circulation mechanism One end of the placement frame is movably connected with the base, and the other end of the placement frame is movably connected with the circulation mechanism; and the moisture absorption materials are placed in the placement frame. After the device is started, air in an environment is sucked by the circulation mechanism, then reaches the placement frame, and then is discharged from the placement frame after being dehumidified. The present invention has the beneficial effects that the structure is simple, and the use is convenient; the complicated structure of a traditional dehumidifier is abandoned, and the cost of a product is reduced to a maximum degree; at the same time, a single dehumidification function is expanded, which can play a role in different use scenes. That is, besides the dehumidification function, functions of atmosphere creation, mosquito repelling (insect repelling), deodorization and the like can also be realized.
