An auto-darkening welding helmet comprises a helmet casing; an auto-darkening filter installed in the helmet casing; and a lighting device installed in the helmet casing, wherein the auto-darkening filter includes a liquid crystal panel which is switchable between a non-opaque state and an opaque state, wherein the lighting device comprises a cable connectable to the auto-darkening filter such that when the liquid crystal panel is in the non-opaque state the lighting device automatically emits light towards a front of the liquid crystal panel and when the liquid crystal panel is in the opaque state the lighting device does not automatically emit light.

Single-use, disposable helmets, hoods, and helmet/hood assemblies are disclosed. Methods of making and using single-use, disposable helmets, hoods, and helmet/hood assemblies are also disclosed.

A wireless communications and light emitting diode (LED) device compatible with conventional helmet structures and adapted, while the helmet is being worn, to effectively illuminate likely illumination targets with an internal lighting device. More particularly, the accessories and applications according to various embodiments of the present invention make use of wireless communication and lighting devices to provide advantages in helmet use, with the ability to answer phone calls, communicate between rider-to-rider or rider-to-passenger, intercom talk hands free, ability to listen to music or voice instructions from GPS navigation, and noise cancelation, for safety, and convenience for the end user.

A helmet includes a lighting system integrated into the helmet. The helmet includes a first layer and a second layer. The helmet includes a plurality of light emitting devices between the first layer and the second layer. A controller is configured to control the light emitting devices. A power source is configured to power the light emitting devices and the controller. The light emitting devices are operably connected to the controller and the power source. In some configurations, a lighting system can be contained in a shell that that can be attached to an existing helmet. In some configurations, a lighting system is contained in a flexible material that can be fitted onto an existing helmet.

A helmet includes a frame having a plurality of tubular segments. The frame includes a cap portion and at least one extension portion. The cap portion includes a plurality of main tubular segments extending from a front of the helmet, configured to be positioned over a forehead of the wearer, to a back of the helmet, configured to be positioned over an occipital region of the wearer's head, and at least one tubular cross segment extending between the main segments. The at least one extension portion includes extending tubular segments that extend from the cap portion to a common point that is configured to be positioned below the wearer's ear. The helmet also includes at least one perforated cover plate mounted to the extending tubular segments, which is configured to cover the wearer's ear and squamous temporal bones of the wearer's head.

A personal sterilization system, including a base unit defining an air intake, a fan, and a fluid path from the air intake to the fan; at least one UVC light source positioned to illuminate at least a portion of the fluid path with UVC light; a delivery conduit attached to the base unit in fluid communication with the fan; and a dispersion device configured to be worn in proximity to a person's face, the dispersion device defining a fluid inlet attached to the delivery conduit, and at least one fluid outlet configured to disperse pressurized air.

An adaptive lighting system for even illumination is provided. In an embodiment, multiple lamps illuminate light in different areas or zones of the surroundings. These lamps modulate their light output in a known (but imperceptible) pattern. One or more light detectors detects light from the surroundings. Light sourced from each lamp is disambiguated and one or more light time-of-flight delays are calculated for each lamp-light detector pair. Based on these calculated delays, illumination levels of the lights are adjusted so as to produce even illumination.

An exemplary illuminated hard hat for providing visibility to workers is presented. The illuminated hard hat allows for the Illumination of the hard hat. Since, the illumination come from inside of the hard hat there no distracting lights to the face. The illuminated hard hat is lightweight and cost effective. The illuminated hard hat further protects workers from injury while meeting OSHA requirements required by law. The illuminated hard hat is useful for construction workers, road workers, mountain climbers as well as anyone who desires to wear a hard hat. While the illuminated hard hat is intended for hard hats, it can also be adapted to be used in any kind of hat worn by people.

A helmet/hood assembly includes a housing, a support ring subassembly configured to hold the assembly on a human head, a face shield, and a flexible hood attached to the housing and to the face shield, with the assembly being received, stored, used, and disposed as a single unit. The support ring subassembly pivots on the housing between a position suitable for shipping and storing the assembly and a position in which the assembly is worn. An accessory light powered by a battery may be held in place on the housing by magnetic attraction through the hood.

A helmet/hood assembly includes a housing, a headband support assembly configured to hold the assembly on a human head, a face shield, and a flexible hood attached to the housing and to the face shield, with the assembly being received, stored, used, and disposed as a single unit. The headband support assembly pivots on the housing between a configuration suitable for shipping and storing the assembly and a configuration in which the assembly is worn. An accessory light powered by a battery may be held in place on the housing by magnetic attraction through the hood.
