A headwear device includes an endothermic reactor and a trigger to initiate an endothermic reaction in a reactor while the headwear device is being worn on a wearer's head. The headwear device may preferably be utilized in, or conjunction with, a motorcycle safety helmet or similar crash protection device. The headwear device is intended to prevent or delay the onset of brain damage as a result of serious trauma or head injury.

The present invention relates to a helmet and a method for dealing with an accident using the helmet, which the helmet includes: a helmet body part made of a resin having a semi-spherical space for receiving the head of a wearer; a light part arranged in the front of the helmet body part having LEDs mounted on a substrate to provide the wearer with lighting; a metallic heat radiator extending from the front of the helmet body part to the back thereof along the upper central line of the helmet body part and partially contacting the back of the substrate to discharge heat; a communication device part received in the helmet body part for dealing with communication and emergency circumstances; and a battery received in the helmet body part for supplying power to the communication part and light part. According to the present invention, the metallic heat radiator is integrated with the resinous helmet body part by injection molding of different materials, so that the heat generated from the LEDs of the light part is discharged upwards from the top of the helmet, thus preventing the wearer from being subjected to the discomfort caused by the heat generated from the LEDs.

This disclosure relates to a brain cooling and spinal cord cooling system, device or mechanism for use in military helmets, and in an adapted format in non-military helmets. The system is comprised of an inflatable pad, or a set of interconnected pads, attached to the interior surface of the helmet, together with a series of valves that allow cooling gases to be delivered from a high pressure canister. The use of different cooling gases permits the achievement and maintenance of cooling of the brain for 24 to 96 hours at a mild (36° C.) or moderate (33° C.-35° C.) brain hypothermia, which is 1.5° C.-4.5° C. below the core temperature.

An activated carbon absorber, in particular an activated carbon absorber for use by a user of an externally ventilated breathing mask or breathing hood. The activated carbon absorber includes a housing for accommodating a filter cartridge, and the housing has the following features: an air inlet supply port to receive compressed air from an air-supply unit; a connector for connecting to a breathing mask or hood; a unit which can be fastened to the body of or to or on the housing of the activated carbon absorber and which is capable of forming a detachable connection with another component in particular a sliding or slip connection.

According to an embodiment, there is provided an extended reality (XR) system based on multimodal interfaces including a computer configured to broadcast output data including at least one device identifier (ID), at least one time limit, and at least one reproduction data to at least one extended reality output device, and at least one extended reality output device configured to receive the output data and reproduces only reproduction data corresponding to itself within the time limit based on the at least one device identifier (ID). According to this, a user can experience reproduction of five senses with a sense of reality without interruption.

A helmet, in particular to a bicycle helmet, having a plurality of ventilation openings and at least one evaporation cooler that is arranged in a ventilation opening.

A protective covering includes an adjustable frame having a headband portion, a face-perimeter portion, and a visor. The covering includes a substantially translucent shield and an air handling unit disposed on the visor. The air handling unit includes a fan and an intake filter disposed in fluidic communication with the fan. A power source is operatively coupled to the fan, and the fan is configured to move ambient air from an external environment, through the intake filter, and into a substantially contained internal environment. A relief filter is at least partially disposed in the substantially translucent shield.

A helmet may include a cooling device coupled thereto, where the cooling device may include a fluid absorbing material that is sufficiently porous to facilitate airflow therethrough positioned within an air intake scoop. The air intake scoop may include a basin formed in part by a front edge of the air intake scoop and by a rear barrier in the air intake scoop. At least one vent aperture located behind the rear barrier. A fluid absorbing material may be disposed within at least a portion of the air intake scoop. At least one drainage aperture may be positioned within a sidewall of the air intake scoop and located at least partially below a top surface of the rear barrier.

A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.

A safety helmet fan system includes a fan housing carrying a first fan on a first side of the fan housing and a second fan on a second side of the fan housing and configured to be mounted, by a mount connector located between the first side and the second side, on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell.
