The invention relates to a protective helmet, and in particular a protective motorcycle helmet, comprising an outer shell (1) for distributing impact forces and a socket (2), which is firmly connected to the outer shell (1), for accommodating an electrical accessory (3), wherein the socket (2) is disposed on an edge (6) of the outer shell (1) and the socket (2) is configured, when accommodating the accessory (3), for guiding the latter substantially along an inner face (7) of the outer shell (1), so that the accommodated accessory (3) extends substantially along the inner face (7) of the outer shell (1).

A configurable site safety system includes a plurality of wearable signaling devices, each with an array of independently addressable lighting elements, a location receiver and one or more communication interfaces. The system may also include a site safety server to track location information received from at least each of the signaling devices, and to cause, based on a subset of the plurality of signaling devices satisfying defined geographical, event-based or other defined criteria, the lighting array of each of the subset of signaling devices to display a defined lighting scheme.

Helmets and helmet lighting systems for use in demanding environments, such as fire, rescue, police and military applications. The helmets and systems provide one or more of high levels of light emission, long operational life, waterproofing/ability to operate in wet or submerged environments and relatively low weight. In some configurations, a helmet comprises a lighting system including an exterior layer and an interior layer applied to a shell of the helmet. In some configurations, a lighting module having an internal layer and an exterior layer is attached to an underlying helmet. In some configurations, a lighting system includes pods and/or strips containing a source of light. The pods or strips can be attached to an underlying helmet.

Provided are a smart window, a sliding smart window, a smart window for a vehicle, a sun visor for a vehicle, a smart window device, and a head-mounted smart window device which have maximized user convenience.

Embodiments relate to an air inflatable type hood for respiration, which includes: a compressed air cylinder having a first micropore formed therein, and filled with compressed air; and an airbag arranged to be able to transfer fluid with the compressed air cylinder and deployable in a helmet shape so as to be able to receive the wearer's head through an injection of the compressed air in the compressed air cylinder.

A helmet body includes an outer shell and an energy management liner with an outer shell lower edge extending between the inner surface and the outer surface of the outer shell. At least two shoulder pad recesses are positioned at a lower edge of the outer shell on a respective left and right sides of the helmet. The energy management liner is adjacent to the inner surface of the outer shell and includes at least two shoulder pads formed of a foamed energy management material. Each of the at least two shoulder pads is received into one of the at least two shoulder pad recesses on the respective left or right side of the helmet, each shoulder pad extending from inside of the outer shell to across at least a majority of a width of the lower edge of the outer shell.

A hands-free headlamp system for an item of headwear, the hands-free headlamp system including: a housing including headwear fastener, the headwear fastener configured to attach to the item of headwear an energy storage affixed to the housing; a light source mechanically coupled to the housing and electrically coupled to the energy storage; a motion sensor mechanically coupled to the housing and electrically coupled to the energy storage, the motion sensor configured to detect hand motion of a user; a controller mechanically coupled to the housing, electrically coupled to the energy storage, and communicably coupled to the motion sensor, the controller configured to operate the light source in response to detected hand motions of the user.

A helmet mounting assembly for attaching helmet accessories to a helmet is provided. The assembly comprises a front-to-back mounting unit comprising at least one rail, grip or connector configured for connecting at least one helmet accessory to the front-to-back mounting unit, whereby the front-to-back mounting unit further comprises a back end configured to enable passage of securing elements there through, and at least one clipping element for attaching the back end of the front-to-back mounting unit to a back edge of the helmet via the securing elements, configured to further pass through the at least one clipping element, and forcefully pulling the front-to-back mounting unit onto the surface of the helmet to squeeze the mounting unit onto the helmet.

A light-emitting beacon a dome e translucent or transparent carapace and a base. A printed circuit board assembly is arranged within the hollow space adjacent the carapace and above and on either side of a battery, the circuit board assembly comprising a plurality of LEDs arranged to emit light out of the carapace and such that when emitting at least one of the LEDs is visible from either side of the carapace. In a particular embodiment the light-emitting beacon is for mounting on a helmet and comprises an elongate carapace a first translucent or transparent material joined to a base having a concave undersurface and manufactured from a second plastic material, the first material of a greater hardness than the second material. The carapace is dome like and at least one LED arranged to emit light out of the carapace.
