The invention is comprising of a mask which will provide air purification with cooling and warming, utilizing tubing filled with controlled by a liquid embedded within cover which can be attached or detachable, but not limited to. The temperature control switch utilizing a thermostat and distributed by pump the liquid can be controlled by utilizing a thermostat or without, and distributed by a pump the cover is provided in different sizes, shapes and styles forms for preference to accommodate the said user requirements for comfort, to conform to the said user requirements for comfort. The utilization of power operation can be a battery connected by USB, or electricity, solar energy and other sources of energy producing elements, but not limited to. Therefore, the cover can be used outdoors or indoors for the comfort of the user. In addition, there is are filters attach and are detachable; filter that will help clean the incoming air, filter that provides a filament of organic herbs scents that are breathable and can be serve medicinal purposes, but not limited to supply healthy fragrance within the Mask. A fan that is attached and can be detachable to provide air circulation from outside that is filtered before it reaches inside the mask to help purify the incoming air. A exhaust valve filter is placed inside mask with a filter attached to exit air outside the mask that is filtered upon when exiting which provides safety to the outside environment.

A personal air filtering device comprising a rigid component comprising a transparent face shield, a fabric component, wherein the face shield and fabric combine to cover an entire head of a user and form a seal around the user's neck, an intake port with an inlet filter, an exhaust port with an exhaust filter, an air mover causing filtered air to enter the intake port from outside the device and exhaust air to exit the exhaust port, and a controller configured to adjust the rate at which the air mover moves air.

A device for filtering air for a user comprising a rigid component comprising, a transparent face shield that provides a space for air between an inside surface of the face shield and the user's face, an intake port, through which intake air enters the device, an exhaust port, through which exhaust air exits the device, a fabric component affixed to the rigid component that, combined with the rigid component, covers the user's head and seals around the user's neck, an intake filter that filters intake air passing through the intake port, an exhaust filter that filters exhaust air passing through the exhaust port, and an air mover assembly mounted on the rigid component that moves intake air through the intake port and exhaust air through the exhaust port, wherein the air mover assembly is mounted on the rigid component by vibration absorbing members, to thereby reduce transmission of the vibration of the air mover assembly to the rigid member, thereby reducing noise from the air mover assembly within the device.

A personal air filtering device for protecting a user from harm, the device comprising a rigid component comprising a transparent face shield, a fabric component, wherein the face shield and fabric combine to cover an entire head of a user and form a seal around the user's neck, an intake port with an inlet filter, an exhaust port with an exhaust filter, an air mover causing filtered air to enter the intake port and exhaust air to exit the exhaust port, one or more sensors, each configured to detect either an environmental condition or a condition of the user, and a processor configured to receive signals from the one or more sensors and execute a protective measure.

A hardhat with a protected overhead cooling fan comprises: a main hardhat body component having an upper aperture through which air is drawn and pulled down into a battery powered cooling fan; a fan cover component spaced at least about ¼ inch from and permanently adhered to the main hardhat body with a plurality of linear ridges; a battery pack for the cooling fan; and a plurality of connecting wires. A method of use is also disclosed.

A personal air filtration system comprising a rigid component, a flexible component, wherein the rigid component and the flexible component combine to cover at least a user's mouth and nostrils and form a seal therearound, an intake port with an inlet filter, an exhaust port, an air mover causing filtered air to enter the intake port and exhaust air to exit the exhaust port, and an app running on a user's smart device, wherein a smart app is configured to control and monitor operation of the system.

Implementations of an intelligent hard hat are provided. In some implementations, the intelligent hard hat comprises a hard hat or hard hat shell and one or more of a lighting component, an audio component, a video component, a communication component, a conditioning component, a power source component, and/or a control component or computer system.

In some implementations, a method of using the intelligent hard hat comprises a lineman putting on the intelligent hard hat. In some implementations, the method comprises the lineman working on an overhead utility line while wearing the intelligent hard hat. In some implementations, the method comprises the lineman using one or more features of the intelligent hard hat while working on the overhead line.

A personal protection system that includes a headband (52) to which a face shield (38) is mounted. A cooling strip (120) is mounted to the headband. The cooling strip includes at least one thermoelectric cooling module (150). A draw strip (128) formed from a flexible thermally conductive material is also part of the cooling strip. The draw strip is bonded to the heat absorbing surface (152) of the thermoelectric cooling module and extends outwardly from the module. A biasing assembly (134, 186) urges the portions of the draw strip spaced from the thermoelectric cooling module against the skin of the individual wearing the personal protection system.

Flexible thermoelectric devices including a flexible heat management layer on the hot side thereof, and methods of making and using the same, are provided. The flexible heat management layer includes a water harvesting material configured to absorb water or moisture and dissipate heat by evaporation of the absorbed water or moisture. In some cases, the water harvesting material includes a mixture of a superabsorbent polymer (SAP) material and a metal-organic framework (MOF) material.

A helmet has a helmet shell. The helmet shell defines an inner space and a passage. The passage has an open end. The passage fluidly communicates with the inner space via the open end. The helmet further comprises an electrical heating device. The electrical heating device is disposed within the helmet shell for heating the passage.
