A protective face mask that includes a power source, ventilation mechanisms, filtering mechanisms, audio and video mechanisms, headphones, a lighting mechanism, a night vision mechanism, a visual zooming mechanism, protective eyewear, a head canopy, a thermometer, a DNA testing mechanism, virus detection mechanisms, radio communication technology, and fiber optics technology.

Described are oxygen control systems that utilize compressed air or oxygen. The oxygen control systems may include a control device having a first inlet that enables the flow of a supply gas from a high pressure gas source at an input pressure into the control device. The control device also includes a second inlet that enables a flow of atmospheric air into the control device and an outlet in fluid communication with the first inlet and the second inlet. The control device also includes a pressure regulator that is operable in a first mode and a second mode. In the first mode, the pressure regulator reduces input pressure of the gas to a first outlet pressure at the outlet, and, in the second mode, the pressure regulator reduces the input pressure of the gas to a second outlet pressure at the outlet that is greater than the first outlet pressure.

Disclosed is a headgear-type device for hazardous air quality warning and air quality improvement, wherein the device can collect biometric information of a worker, wired and wireless communications, and information about the quality of outside air around the worker so as to warn the worker of a hazard or improve air quality at the site. The headgear-type device for hazardous air quality warning and air quality improvement according to the present invention may comprise: a headgear-type biometric sensor which comes into close contact with the head of the worker so as to sense biometric information of the worker and thus allow measurements of the worker's physical conditions; a terminal which is wiredly or wirelessly connected to the headgear-type biometric sensor so as to transmit and receive the biometric information; and a server which receives the biometric information from the terminal, calculates, on the basis thereof, whether the biometric information is in a normal condition range, according to a program, and when the biometric information is not in the normal condition range, issues a warning to the worker by transmitting a warning state to the terminal.

A device for enhancing efficiency of an air mask (204) wearable by a user to cover the mouth and nose of the user includes an elongated chamber (202) fluidly couplable at a proximal end thereof to an air opening (205, 205′) of the mask (204). A filter element (206) formed of flexible material is wrapped around a sidewall of the chamber either internally or externally and has a surface area that is at least twice as large as that of the mask for filtering air flowing through the chamber in either direction, and a one-way valve (227, 228) is mounted in association with the opening for allowing filtered air inhaled by the user to pass from the chamber to the mask or for allowing an air exhaled by the user to pass from the mask to the chamber.

A protective system for respiration, and a management method facilitates stably supplying filtered air for safety such that the equipment management or the safety management can be performed remotely. The protective equipment includes a main body that covers the face of an operator, a fan unit including an air filter and an electric fan, a detecting section, a first control section, and a first communication section. The detecting section detects a physical quantity concerning at least one of a work environment of the operator, an action state of the operator, and an operation state of the electric fan. The first control section controls the electric fan based on a detection result of the detecting section. The first communication section transmits first information indicating a detection result of the detecting section or second information concerning an operation amount on a control target of the first control section to an external device.

Provided is a powered air blower unit for delivering air flow to a user with constant air flow or varying speeds of air flow. The air blower unit may also include a filter for purifying the air.

The present invention relates to a face mask that protects the wearer from pathogens while enabling the wearer to be heard clearly, even at larger distances. The face mask can be a multilayered mask having a vent for expelling exhaled air and a combination of a microphone and a speaker for capturing and amplifying the sound of the wearer. Further, the face mask includes a temperature sensor for sensing the real-time temperature of the wearer, and an oxygen sensor for monitoring the blood oxygen level of the wearer. The temperature and the oxygen level can be transmitted to a paired software application installed in an electronic device for visualization and processing. The face mask amplifies the voice in situations where it is difficult to project same through the mask.

A breathing apparatus may include a heater configured to kill harmful organisms in air. The apparatus may include a vest, including a heating chamber disposed on the vest and a cooling chamber disposed on the vest. The heating chamber may include a heat source, and the heat source may heat air disposed within the heating chamber to a predetermined temperature. The heating chamber and the cooling chamber may be in fluid communication. The apparatus may include a breathing tube, including a first end and a second end. The first end may connect to the cooling chamber. The apparatus may include a breathing mask. The second end of the breathing tube may connect to the breathing mask. The cooling chamber and the breathing mask may be in fluid communication via the breathing tube.

A portable air processing system that takes air from the ambient or other component, heats the air to a sufficient temperature so as to deactivate at least one type of pathogen or allergen, then cools the air to a comfortable breathing temperature, and then feeds this processed air under positive pressure to a controlled environment or mask covering the nose and mouth of a wearer, thus enabling one to breath cleaner air from a controlled source while mobile or stationary.

An improved safety device for a self-contained breathing apparatus, and an improved self-contained breathing apparatus having thermal imaging capabilities.
