Abstract

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.

First claim

What is claimed is:

1. A diffuser headband system, comprising:
a sanitized air generating source that produces sanitized air, wherein the sanitized air generating source comprises an air distribution apparatus coupled to one or more diffusers, the one or more diffusers comprising a perforated elastic tube, the perforated elastic tube comprising a plurality of apertures spaced along a surface of the elastic tube, the perforated elastic tube further comprising an inlet that receives the sanitized air from an outlet of the air distribution apparatus, wherein the plurality of apertures expel the sanitized air in a generally downward direction to provide an air shield by creating a 360-degree wall of air below the air distribution apparatus; and
a diffuser headband formed from an elastic material comprising a substantially oval shape and an elastic tube attached to the elastic material, wherein a first portion of the elastic tube comprises a plurality of apertures spaced along a surface of the elastic tube, wherein a second portion of the elastic tube, detachably coupled to the sanitized air generating source, comprises an inlet that receives the sanitized air from the sanitized air generating source, wherein the plurality of apertures receive the sanitized air from the inlet and expel the sanitized air to provide an air shield that encircles a body of a person wearing the diffuser headband by creating another 360-degree wall of air, and wherein the air shield blocks aerosol droplets generated by the person wearing the diffuser headband.

2. The system of claim 1 , wherein the air shield further blocks aerosol droplets within an enclosed space outside of air shield from reaching the person wearing the diffuser headband.

3. The system of claim 1 , wherein the inlet of the elastic tube is coupled to an outlet of the sanitized air generating source.

4. The system of claim 1 , wherein the air shield comprises a plurality of air jets.

5. The system of claim 1 , wherein the air distribution apparatus produces the sanitized air from a height above an enclosed space including the person and one or more additional persons.

6. The system of claim 5 , wherein the enclosed space comprises the person wearing the diffuser headband and one or more additional persons wearing the diffuser headband.

7. The system of claim 1 , wherein the one or more diffusers comprise a substantially oval shape.

8. The system of claim 1 , wherein the one or more diffusers are capable of swiveling about at least one of a horizontal axis and a vertical axis.

9. The system of claim 1 , further comprising one or more additional diffuser headbands.

10. The system of claim 9 , wherein the one or more additional diffuser headbands are worn by one or more additional persons occupying an enclosed space comprising the sanitized air generating source.

11. A diffuser headband apparatus, comprising:
a solar adiabatic cooling vest;
an elastic material comprising a substantially oval shape; and
an elastic tube attached to the elastic material, wherein a first portion of the elastic tube comprises a plurality of apertures spaced along a surface of the elastic tube, wherein a second portion of the elastic tube comprises an inlet that receives sanitized air from the solar adiabatic cooling vest, wherein the plurality of apertures receive the sanitized air from the inlet and expel the sanitized air to provide an air shield that encircles a body of a person wearing the diffuser headband apparatus, and wherein the air shield blocks viral aerosol droplets generated by the person wearing the diffuser headband apparatus.

12. The apparatus of claim 11 , wherein the air shield further blocks aerosol droplets within an enclosed space outside of the air shield from reaching the person wearing the diffuser headband.

13. The apparatus of claim 11 , wherein the air shield comprises a plurality of air jets.

14. A diffuser headband system, comprising:
a sanitized air generating source that produces sanitized air, wherein the sanitized air generating source comprises an air distribution apparatus coupled to one or more diffusers, the one or more diffusers comprising a perforated elastic tube, the perforated elastic tube comprising a plurality of apertures spaced along a surface of the elastic tube, the perforated elastic tube further comprising an inlet that receives the sanitized air from an outlet of the air distribution apparatus, wherein the plurality of apertures expel the sanitized air in a generally downward direction to provide an air shield by creating a 360-degree wall of air below the air distribution apparatus; and
a diffuser headband formed from an elastic material comprising a substantially oval shape and an elastic tube attached to the elastic material, wherein a first portion of the elastic tube comprises a plurality of apertures spaced along a surface of the elastic tube, detachably coupled to the sanitized air generating source, wherein a second portion of the elastic tube comprises an inlet coupled to an outlet of the sanitized air generating source, wherein the inlet receives the sanitized air from the sanitized air generating source, wherein the plurality of apertures receive the sanitized air from the inlet and expel the sanitized air to provide an air shield comprising a plurality of air jets, wherein the plurality of air jets encircle a body of a person wearing the diffuser headband by creating another 360-degree wall of air, wherein the air shield blocks viral aerosol droplets generated by the person wearing the diffuser headband, and wherein the air shield further blocks viral aerosol droplets within an enclosed space outside of air shield from reaching the person wearing the diffuser headband.
