A head covering 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, and an environmental control component to condition air within the device.

Protective headgear including central, left lateral, and right lateral trunks, and which may include at least one external, remote handle for directing air flow.

Example hard hat adapters include: a coupling mechanism to removably couple the hard hat adapter to a hard hat; an upper arm configured to removably couple to an outer face shield and an inner face shield; and a lower arm configured to removably couple to a blower shell, wherein the outer face shield and the inner face shield are configured to removably couple to the hard hat adapter at a first pivot point of the hard hat adapter.

A hard hat style helmet includes a powered and filtered air intake and distribution system. The air distribution system directs filtered air into a breathing mask structured and located to cover a wearer's mouth and nose. The helmet includes wireless telecommunication features and a speaker and microphone to enable hands-free voice calling. The helmet also includes a camera for transmitting the wearer's field of view. The helmet also includes a transparent display inside the wearer's field of view and another display outside the wearer's field of view.

A ballistic helmet comprising a ballistic shell, wherein within the thickness of the ballistic shell, or inside the ballistic shell, there is provided one or more circuit layers forming a circuit, which circuit comprises a power bus and a data bus, and wherein one or more power connections and one or more data connections are provided on the inside and/or on an edge of the ballistic shell for providing power and data to/from one or more electrical devices through the circuit.

Provided is a head protection device with multiple face shields, where the head protection device is configured to be able to provide a flow of air to a user of the head protection device. The air flow may be provided by an external air providing device.

A wearable air filtration apparatus configured to fit beneath a full-face helmet is disclosed. The apparatus includes a front plate including an output aperture and at least one input aperture, the input and output apertures arranged to be substantially front facing when the apparatus is worn by a user. An air filter is arranged behind the front plate and positioned to filter air moving from in front of the apparatus toward the face of a user wearing the apparatus. A valve plate is located behind the filter, the valve plate including an output check valve in fluid communication with the output aperture and at least one input check valve in fluid communication with the at least one input aperture.

Air purifying respirator for user's having a face shield configured to shield the user's face from splatter, a head strap configured to encircle at least a portion of the users head, said head strap configured to support the face shield, at least one fan, and a fan housing positioned proximate an upper edge of the face shield, said fan housing configured to support said fan, a filter media positioned on an outer perimeter flange of the fan housing to maximizing a surface area of said filter media, a face shroud connected to a perimeter of the face shield, the face shroud configured to provide a seal between the face shield and the user's face and thus, to facilitate pulling the air through the filter media, and the fan pushes the filtered air from said fan housing to the user between said face shield and the user's face.

A system of head protection with an integrated air filtration mechanism for protecting the user from impact/concussion and ambient air pollution. Example embodiments comprise a rigid helmet shell covering the head of the user and a fabric air barrier around the user's neck, a battery powered filtered centrifugal fan contained inside an external detachable cowl apparatus adjoins to a helmet external top spoiler with a mounting system that is easily removable to meet impact attenuation standards. The cowl apparatus directs clean filtered air into the duct system—a top spoiler funnel connected to an internal clean air duct and exits the visor air curtain providing continual clean laminar airflow between the user's face and the face shield. One or more sensors, calibrated to detect harmful particulates and a processor to automatically activate the system as a protective measure when harmful particulates are encountered and a sensor to detect when filter element needs replacement.

A sterile body suit apparatus, system, and method is provided. In certain embodiments, the sterile body suit apparatus may comprise a helmet member, a lower extremity member, and a control interface means. The helmet member may comprise a respiratory means to provide uncontaminated, breathable air to a wearer, an ingestion means for drinking, eating, and vaping, and an audio communication means. The lower extremity may be defined by a torso, a first arm, and a second arm, and may further comprise an egestion means. Moreover, in some embodiments, the sterile body suit may further comprise a temperature control means and a tactile sensation means. The sterile body suit method may comprise the steps of: providing one or more mobile computing devices; providing one or more body suits at an environment having a local computing device; receiving, at the one or more mobile computing devices, a suit selection; generating and transmitting, at the one or more mobile computing devices, a suit selection notification; receiving, at the local computing device, the suit selection notification; and preparing and delivering, at the environment, the one or more body suits to one or more wearers.
