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.

A hair cooling and dehumidification apparatus is disclosed. The apparatus comprises a wearable headgear/two-part fitness cap having an inner cavity for receiving a portion of a user's head. The wearable headgear comprises a top/outer insert and a bottom/inner insert. Both inserts comprise a plurality of offsets to maintain an air space gap between them. A pouch holder is provided to secure a desiccant pouch and attached to the top insert to absorb the water vapour from user's hair. The apparatus further comprises a thermo-electric cooling system having a thermoelectric cooler. A small heat sink is attached to a cold side of the thermoelectric cooler whereas a large heat sink is attached to a hot side. Further, a blower unit is attached to the small heat sink which is connected to the cold side of the thermoelectric cooling plate, to circulate the ambient air within the housing over the cold heat sink, to cool the incoming air circulating within the housing, thereby providing cooling and dehumidification of user's hair.

A method is described for producing a vaccine from a neutered pathogenic source. The neutered pathogenic source may be a SARS-COV-2 virus that is neutered with a defined dose of UV-C light. The neutered SARS-COV-2 viral vaccine is administered through an inhalation pump.

An air cooler includes a body having a top portion, a bottom portion, and a middle portion situated between the top and bottom portions. The air cooler further includes a fan disposed in the top portion of the body. The fan includes a fan hub and a plurality of fan blades centrally attached to the fan hub. The air cooler also includes a first mister disposed at a first location within the body. The first location is in front of the plurality of fan blades in the top portion of the body. The air cooler further includes a second mister disposed at a second location within the body. The second location is in front of the plurality of fan blades in the top portion of the body and different from the first location.

A system and method for creating a microenvironment within an ambient environment is disclosed. The first outlet is configured for expelling a gas at a first velocity sufficient for producing a gas curtain that separates the microenvironment from the ambient environment. The second outlet is configured for expelling the gas at a second velocity within the microenvironment. An inlet is spaced apart from the first outlet and the second outlet and is in fluid communication with a suction unit. The suction unit is positioned downstream of the inlet and configured for removing gas from the microenvironment through the inlet. The first velocity is greater than the second velocity.

A mister-fan apparatus includes: a housing having a fan end and a reservoir end; at the fan end, a fan unit; at the reservoir end, a reservoir; a motor; a pump; an inlet conduit from the reservoir to the pump; and an outlet conduit from the pump to the fan unit, collectively configured for, through the use of the inlet and outlet conduits, pumping fluid from the reservoir to the fan unit so that the fan can output mist; a track peripherally surrounding the housing at least partway around; an attaching device having an attaching end and an extension end; a tongue having a track end, and a connection end connected to the extension end; and, within the track, a retaining slider connected to the track end; wherein the attaching end is configured for removably attaching to an external structure for supporting the apparatus. The track may include a pair of ridges, rigidly connected to the housing, that extend initially outwardly from the housing, and later toward each other but only to an extent of leaving a separation serving as a slot.

An apparatus is provided for preventing the spread of air-borne contaminants in a defined space. The apparatus comprises an air flow outlet adjacent to or within the defined space, an air flow inlet adjacent to or within the defined space, and a conduit for transporting air from the air flow inlet to the air flow outlet. An air treatment module is provided within or adjacent the conduit for extracting air-borne contaminants from air transported from the air flow inlet to the air flow outlet. The air flow outlet deposits air into the defined space substantially evenly across an outlet area.

The invention discloses an indoor adaptive ventilation system and method based on multi-vent ventilation modules, comprising at least one multi-vent ventilation module, the multi-vent ventilation modules comprise air reversing valves and ventilation ducts, the multi-vent ventilation ducts are connected with the air reversing valves, the air reversing valve comprises a box body, a box cover, a reversing mechanism, a supply air main duct, a return air main duct, a fixed supply air branch duct and multiple variable air direction branch ducts; a plurality of variable air direction branch ducts are evenly arranged in the circumferential direction of the box body. The invention can divide the indoor space into different sub-spaces, control pollutants in a smaller area, reduce the possibility of large-scale pollutant diffusion, and realize that the supply air outlets and the return air outlets can be switched mutually to adapt to different usage scenarios and needs.

A portable cooling apparatus or air conditioner is disclosed herein. The apparatus has a case defining an interior volume. The interior volume contains a cooling substance such as cold water or ice, an intake port, and an exit port. A pathway is defined between the intake port and the exit port for air to pass through the case. The pathway may be defined by a pipe. Alternatively the cooling substance may be contained within one or more containers insertable into the case and that define a pathway between the sides of the containers. A fan with a power source is provided to drive air through the case and pathway. The air is cooled by heat transfer with the cooling substance.

A headgear is described that includes an air purifier, a microphone, and a control unit. The control unit analyses a signal output by the microphone to determine a magnitude of wind. The control unit then controls a flow rate of the air purifier in response to the determined magnitude.
