Disclosed example respirators comprise: a filter configured to filter the air; a blower fan configured to provide continuous air flow at variable speeds; an air duct configured to direct air from the blower fan to an exhaust location, the blower fan configured to blow air through the air duct; and a blower controller configured to: control the blower fan to automatically adjust an airflow speed of the blower fan to a plurality of airflow speeds over a plurality of different time periods, the plurality of airflow speeds being within an airflow speed range.

Method and apparatus for providing air flow

A welding-type helmet includes a cover with a channel recessed from an external surface of the cover, the channel being configured to house a removable light source within the channel.

In one aspect, a protective headwear is provided and includes a headgear, an outer shell, a duct and a manifold. The headgear is configured to engage a wearer's head and at least partially support the protective headwear on a wearer's head. The headgear includes a front, a rear opposite the front, a right side, and a left side opposite the right side. The outer shell is coupled to the headgear at a coupling location and includes a shield positioned to the front of the headgear. The duct is at least partially coupled to and at least partially positioned in an interior of the outer shell. The duct is located below the coupling location. The manifold is positioned to the rear of the headgear and configured to divert airflow into at least a first portion of airflow and a second portion of airflow

Protective headwear with airflow

A welding helmet system is provided. The welding helmet system includes a protective shell and a welding display system. The welding display system is configured to be removably coupled to the protective shell. The welding display system is configured to receive data from a sensor, and to display a welding metric derived from the sensor via the image generation system.

Augmented and mediated reality welding helmet systems

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.

In one aspect, a protective headwear is provided and includes an outer shell, a first shell duct coupled to the outer shell and including a first exhaust port, and a second shell duct coupled to the outer shell and spaced apart from the first shell duct. The second shell duct includes a second exhaust port. The protective headwear also includes a manifold positioned externally of the outer shell and configured to divert airflow into at least a first portion of airflow and a second portion of airflow. The manifold includes a first diversion member coupled to and in fluid communication with the first shell duct to provide the first portion of airflow to the first shell duct, and a second diversion member coupled to and in fluid communication with the second shell duct to provide the second portion of airflow to the second shell duct.

A welding helmet for detecting arc data is provided. One embodiment of the welding helmet includes an arc detection system configured to detect one or more welding arcs that occur during one or more welding operations. The welding helmet also includes control circuitry configured to count a number of the one or more welding arcs detected by the arc detection system. The welding helmet includes a storage device configured to store the number of the one or more welding arcs.

A system for attaching a welding face member to a hard hat includes a hard hat and an adapter. The adapter is attached to the hard hat. The adapter includes an adapter mating member which attaches to a welding face member. The adapter mating member is located below the hard hat.

Hard hat adapter for a welding face member

In one aspect, a protective headwear is provided and includes a headgear, an outer shell rotatably coupled to the headgear, and a first shield coupled to the outer shell and rotatable between a first position and a second position. The first shield is selectively removable from the outer shell without the use of tools. The protective headwear also includes a second shield coupled to the outer shell. The first shield covers the second shield to a greater extent in the first position than in the second position. In one aspect, a method of manufacturing a protective headwear is provided.

Removable shield for protective headwear

Provided is a light attached to a helmet where the light does not move when a face shield of the helmet is rotated up or down.

Method and apparatus for attaching a light to a head-worn device

In one aspect, a protective headwear is provided and includes a support member configured to engage a user's head, an outer shell coupled to the support member and rotatable relative to the support member between a first position and a second position, and a member coupled between the support member and the outer shell to reduce angular velocity of the outer shell as it moves from the first position to the second position. In one aspect, the protective headwear is a welding helmet.

Apparatus for reducing angular velocity of protective shells associated with protective headwear

In one aspect, a headgear for engaging and supporting protective headwear on a wearer's head includes a first side member positioned on a first side of the headgear, a second side member positioned on a second side of the headgear opposite the first side, a forehead strap coupled to the first and second side members and positioned on a front half of the headgear, and an occipital strap having an end coupled to one of the first side member and the second side member on the front half of the headgear and the occipital strap extending to a rear half of the headgear.
