Various embodiments are directed to a diffuser headband system. The system may include a diffuser headband formed from an elastic material coupled to a sanitized air generating source that produces sanitized air. The diffuser headband may form a substantially oval shape and include an elastic tube attached to the elastic material. A first portion of the elastic tube may be perforated to include a group of air outlet holes spaced along a surface of the elastic tube. A second portion of the elastic tube may include an inlet that receives the sanitized air from the sanitized air generating source. The air outlet holes receive the sanitized air from the inlet and expel the sanitized air to provide an air shield that encircles a person's body wearing the diffuser headband. The air shield blocks viral aerosol droplets from entering or leaving an airspace occupied by the person wearing the diffuser headband.

An integrated system and process provides integrated control of the environment within a personal space. A tent or other structure suitable for forming a personal space, is in contact with, and may enclose, a user station. The system includes a control system, main controller, control modules, sensors, environmental units and other controllers that operate in an integrated fashion to provide a controlled environment within the personal space. The tent may enclose all or portions of the control system, main controller, control modules, sensors, environmental units and other controllers. Portions of the control system, main controller, control modules, sensors, environmental units and other controllers may reside outside tent. A process for providing environmental control of the personal space includes learning capabilities.

A personal cooling device includes a rigid ventilation tube that is curved in part to fit around the neck of a human user such that the entire device may be supported solely in this manner. A powered fan is located at one end of the ventilation tube and configured to force air through the ventilation tube. Ventilation holes are arranged to direct air leaving the ventilation tube toward a user's body. A hollow compartment is provided in the ventilation tube adjacent the fan and is configured to received a portion of ice or other frozen material as a frozen liquid-filled sponge to effect evaporative cooling of passing air.

An air purification unit is provided for individuals seated at a table that has a unit body adapted to be mounted at a mounting height at or above the approximate head height of individuals seated at the table, and in a position between the individuals. A motorized fan system is provided within the unit body that is configured to draw air from at least one inlet proximate the bottom of the unit body. A filter is positioned in communication with the inlet and the fan system for filtering air drawn through the inlet. The unit body has at least two ducted outlets disposed radially or axially for discharging filtered air toward the individuals, while the unit prevents cross-flow of breath air between the individuals.

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.

Body-worn air-treatment devices comprise a body that is configured to be selectively coupled proximate to a respiratory tract inlet of a living individual, and a pathogen-deactivating mechanism that is supported by the body. Methods comprise deactivating pathogens proximate to a respiratory tract inlet of a living individual.

An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which switches between first control and second control at a predetermined timing. The first control makes a sympathetic nervous system of the subject dominant over a parasympathetic nervous system of the subject by changing a wind speed of the wind that is blown by the wind blower at a predetermined cycle, and the second control makes the parasympathetic nervous system of the subject dominant over the sympathetic nervous system of the subject by decreasing a wind speed of the wind that is blown by the wind blower to a wind speed lower than the wind speed in the first control.

Ionizers having carbon nanotube (CNT) ion emitting heads of the present invention include ionization circuitry supplying voltage at ionization potential and carbon nanotube (CNT) ion emitters operatively connected thereto. The carbon nanotube (CNT) ion emitters are mechanically and electrically stable, provide good ion flows for air purification and/or air invigoration when actuated at ionization potential and are capable of prolonged use in highly polluted environments.

A personal mister system includes a manually operated mist delivery assembly having a trigger actuated spray bottle and water delivery tubing configured to deliver water from the spray bottle to a series of mister nozzles positioned along a portion of the water delivery tubing provided in a circular configuration. The portion of the water delivery tubing provided in a circular configuration is removably attachable to a user selected hat. A bottle carrier is further provided for carrying the spray bottle in a handsfree manner. The device supplies mist to a user to lower the body temperature of the user and provide immediate cooling effects.
