A device or system is provided that provides olfactory stimuli, and includes a piezoelectric vibration device that is used to produce scents corresponding to actions performed in a VR or AR environment, or other application. In some implementations, a user interacts with one or more game elements within a game program being executed by a game engine, and responsive to the interaction, the game engine may communicate a series of commands that cause a piezoelectric device of the device to generate scents to be experienced by the user.

A mobile device and method for using a mobile device to disinfect by eliminating bacteria, viruses, and pathogens is provided. The mobile device includes a disinfecting light emitting diode that emits UVC light only in the range of 200 nm to 220 nm to disinfect without harming human tissue. Disinfecting of an object or surface can be accomplished using the mobile device by turning on the LED to provide UVC light in a range of 200-220 nm and holding the mobile device about 0.5 to about 3.0 inches from an object to be disinfected.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

The present invention relates to a perfume dispensing device, the device being electronically controlled and the actuation of perfume spraying being performed via an actuator (12) located on or under a device housing (1). All components of the device are located on or in the housing (1), wherein the housing also accommodates a control circuit (10) for controlling the device, which may optionally include a system (13) for wireless communication with a smart device (14) having a dedicated application uploaded, through which the user sets the desired parameters. The device may include several storage containers (2), which allows the user to select the desired perfume or to personalise the perfume via a dedicated application. The actuator is actuated by pressing or touching the actuator (12) or via an external device.

A modular air treatment unit for an over the road vehicle is independent of an associated climate control system. The air treatment unit is configured to filter and sanitize air within the passenger compartment as air moves along a flow path separate from a flow path through the climate control system. The modular air treatment unit includes a housing defining a circuitous passageway, an air filter mounted to the housing, a fan configured to move air along passageway, and an ultraviolet light source arranged in the housing. The ultraviolet light source is configured to discharge germicidal ultraviolet light inside the housing to eliminate pathogens in the housing.

A system including tubing and a filter configured to be fluidly coupled to a vacuum source and to a heater/cooler unit by the tubing. The filter includes a filter container having negative air pressure in the filter container provided by the vacuum source to pull aerosol from the heater/cooler unit into the filter container and eliminate and/or reduce the aerosol emitted from the heater/cooler unit.

A clothes dryer using an LED light source is proposed. Instead of using a heater, a blowing fan, and a heat exchanger, the clothes dryer employs a plurality of LED light source modules provided in a body and efficiently arranged therein and an air circulation structure of an air circulation part having a blowing fan arranged in the inner rear side thereof, and is configured to sterilize air through an air sterilization part, absorb and dry moisture by a ceramic filter, and then finally discharge the air to the outside through an exhaust fan. Therefore, without requiring a separate water discharge treatment process in an existing method, the clothes dryer can achieve efficient drying of clothes and drying of clothes without damage.

A torchiere style sanitizing device for disinfecting airborne pathogens while providing aesthetic area lighting. A reversible fan exchanges air between the upper room air plume and the lower air plume by passing the air through a center disinfecting section. The disinfection section may include a linear UV-C light, reflective tube, and light trap positioned at one or both ends of the disinfection section to maximize the exposure of the air to the UV-C light and contain the UV-C light within the device. The device includes a conventional illumination source in an upper shade and can selectively provide one of more of room air flow, room air disinfection, and room illumination.

A diffuser having a plurality of atomizers associated with a single pump is provided. The diffuser may include four or more atomizers that may be removably coupled to the diffuser. Each atomizer may store the same or different oils. In some embodiments, the outlet of the atomizer may have a tortuous passageway to prevent diffusion of large oil droplets. The diffuser includes a plurality of valves associated with the plurality of atomizers, such that the valves may be selectively actuated to permit flow to the selected atomizers.

Provided is a release device including a housing having an inlet and an outlet, a heating element arranged in the housing, a first fan arranged to move air into the inlet and around the heating element, and a second fan arranged to move vapor out of the outlet. Other embodiments and arrangements are disclosed.
