A wearable mask includes a light module attached to a cover. The light module includes an inlet for receiving air to be breathed in by the person, and an outlet that faces the person. Airflow paths extend between the inlet and the outlet, and receive air to be breathed in by the person. An ultraviolet (UV-C) light source emits anti-microbial light into the one or more airflow paths at a wavelength that kills microorganisms in the air in the one or more airflow paths. Walls at the inlet and outlet each includes one or more slits through which the air passes. The one or more slits of each wall are offset relative to the one or more slits of an adjacent wall to form staggered airflow paths that allow the air to pass through offset slits, but blocks the anti-microbial light from passing through the offset slits.

The present disclosure relates to a mask including: a mask main body being pressed against a face of a user, and forming an internal space for receiving air in front of a nose and a mouth of the user; and an air purifying module mounted in the mask main body, and having a first passage for allowing outside air to flow in a direction perpendicular to a side surface of the air purifying module, while forcing the air to flow into the nose and mouth of the user, in which by providing a first passage, a non-uniform suction flow may be reduced, such that an area of a filter may be used efficiently, and noise may be reduced.

A headband for a wearable electronic device includes a first end portion, a second end portion, and a central portion disposed between the first and second end portions. The first end portion is connected to the central portion by an extension mechanism for adjusting a length of the headband, and the first end portion includes a battery compartment for receiving a battery.

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.

An exposure-indicating supplied air respirator system comprises a head top, a clean air supply source and a portable personal communication hub. The head top comprises a visor that is sized to fit over at least a user's nose and mouth, a position sensor secured to the head top, and a head top communication module. The clean air supply source is connected to the head top that supplies clean air to the interior of the head top. The position sensor detects whether the visor is in a closed position or in an open position and the head top communication module communicates the visor position to the personal communication hub. If the personal communication hub receives a signal indicating the presence of a hazard, and if the visor is in an open position, an alert is generated.

In some examples, a system includes an article of personal protective equipment (PPE) comprising one or more sensors, the one or more sensors configured to generate usage data that is indicative of an operation of the article of PPE; and at least one computing device comprising a memory and one or more computer processors that: receive the usage data that is indicative of the operation of the article of PPE; apply the usage data to a safety learning model that predicts a likelihood of an occurrence of a safety event associated with the article of PPE based at least in part on previously generated usage data that corresponds to the safety event; and perform, based at least in part on predicting the likelihood of the occurrence of the safety event, at least one operation.

In some examples, a system includes an article of personal protective equipment (PPE) having at least one sensor configured to generate a stream of usage data; and an analytical stream processing component comprising: a communication component that receives the stream of usage data; a memory configured to store at least a portion of the stream of usage data and at least one model for detecting a safety event signature, wherein the at least one model is trained based as least in part on a set of usage data generated by one or more other articles of PPE of a same type as the article of PPE; and one or more computer processors configured to: detect the safety event signature in the stream of usage data based on processing the stream of usage data with the model, and generate an output in response to detecting the safety event signature.

A personal protected-air system includes a ring adapted to fit over a user's head. The ring includes a port for receiving breathable air, a manifold in fluid communication with the port, and vents in fluid communication with the manifold. The vents are distributed about a portion of the ring. A face mask is coupled to the ring. The face mask has a first edge, a second edge, and mask material extending from the first edge to the second edge. The first edge is coupled to the ring adjacent to the portion thereof where the vents are so-distributed. The second edge is adapted to fit snugly against the user's cheeks and nose bridge wherein the mask material is spaced apart from the user's nostrils and mouth by an air space and wherein the breathable air enters the air space via the vents

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

In some examples, a system includes an article of personal protective equipment (PPE) having at least one sensor configured to generate a stream of usage data; and an analytical stream processing component comprising: a communication component that receives the stream of usage data; a memory configured to store at least a portion of the stream of usage data and at least one model for detecting a safety event signature, wherein the at least one model is trained based as least in part on a set of usage data generated by one or more other articles of PPE of a same type as the article of PPE; and one or more computer processors configured to: detect the safety event signature in the stream of usage data based on processing the stream of usage data with the model, and generate an output in response to detecting the safety event signature.
