A protective helmet has an outer shell configured for surrounding a head of a user and at least one accessory attachment rail connected to the outer shell. The accessory attachment rail has a body having a front end, a rear end, and one or more slots between the front end and the rear end. Each of the one or more slots is configured for removably receiving at least one helmet accessory. A locking mechanism is associated with each of the one or more slots for automatically locking the at least one helmet accessory in the one or more slots upon insertion of the at least one helmet accessory within the one or more slots and for preventing removal of the at least one helmet accessory from the one or more slots. At least one connection element is provided for connecting the accessory attachment rail to the outer shell.

A barrier system, device, and method protects medical professionals and patients from exposure to contaminants and bodily fluids. The system includes a head unit (e.g., 708) shaped to be worn over the head of the wearer; a hood (e.g., 704) positioned over the head unit; one or more sensors (e.g., 1902) configured to produce one or more sensor-output signals; and a controller (e.g., 1904) connected to the one or more sensors and configured to produce one or more controller-output signals based on the one or more sensor-output signals. Further, a device inside a barrier system is controlled by (a) sensing one or more characteristics; (b) producing one or more sensor signals based on the sensed one or more characteristics; (c) converting and/or processing the one or more sensor signals to produce one or more controller-output signals; and (d) controlling the device based on the one or more controller-output signals.

A wearable communications assembly is worn by a user and includes a wearable device adapted to be worn by an individual in a defined area. A contextual sensor such as an environmental sensor is affixed to the wearable device in a manner such that the contextual sensor senses a condition of the defined area. The contextual sensor creates a contextual signal. The wearable communications assembly also includes a storage device electrically connected to the contextual sensor for receiving and storing the contextual signal such for download when the wearable communications assembly is in communication with system apart from the wearable communications assembly. The communication between the wearable communications assembly and the system apart therefrom may be wireless and/or wired.

Glasses for a helmet is configured to rotate a glass member in a state where the glass member is mounted onto the helmet by means of one touch, thereby allowing the glass member to be located in front of a wearer's eyes, and configured to reversely rotate the glass member, thereby opening the front sides of his or her eyes. The glasses for a helmet includes: helmet attachment members fixedly attached to the helmet worn on a wearer's head; glass mounting members separably mounted onto the helmet attachment members by means of one touch; and a glass member adapted to rotate in a state of being rotatably fixed to the glass mounting members in such a manner as to be located in front of the wearer's eyes.

A smart headlamp system and methods of use thereof are provided herein. A computer-implemented method includes automatically measuring orientation values attributed to a lighting system device worn by a human user, wherein the lighting system device comprises one or more lighting sources and one or more infrared radiation sensors; automatically measuring infrared radiation values detected within a given proximity of the lighting system device; and automatically modulating one or more of the lighting sources based at least in part on (i) the measured orientation values and (ii) the measured infrared radiation values.

An airbag system for protecting a body part of a user in case of an accident is provided. The system including an airbag adapted for inflation upon an accident occurring during an intended activity, at least one sensor configured to measure movements of the airbag system, and thus indirect the movements of the user and a control unit configured to determine if the user is in a first activity state not corresponding to the intended activity by processing the output from the at least one sensor.

An airbag system including an airbag and a detachable shell enclosing the airbag when the airbag is in a non-inflated state, and at least one size adjustment mechanism. Further, an inflatable helmet having such airbag system, and an item of apparel having such airbag system are provided.

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.

A hard hat with symmetric front and back mounting ridges to support a headlamp is described. The hard hat provides mounting ridges to receive insertion slots of a rigid mounting bracket that fit around the ridges. The rigid mounting bracket includes channels to loop a strap through the channels and support a lamp on the bracket. The strap may include a hook and loop fastener system to enable attachment of a variety of lamps to the rigid support bracket. In this way, the hard hat can support a wide variety of headlamps attached to the rigid mounting bracket without destructive alterations to the hard hat. Clips may be added to the rigid mounting bracket to secure or lock the bracket in place during operation and prevent accidental knocks or jarring of the headlamp.

An impact diffusing system for protecting a user's head includes a headpiece cage coupled to a thoracic framework. In one aspect, the headpiece cage includes at least two support bars, a plurality of rigid bars surrounding at least a portion of the forehead, top, and sides of the head, and a face mask that encloses at least a portion the user's face. The thoracic framework covers at least a portion of a chest, upper back, and shoulders of the user, and the thoracic framework is attached to the support bars of the headpiece cage in a manner that prevents movement of the headpiece cage relative to the thoracic framework. In another aspect, the system includes a helmet component (formed of e.g., carbon fiber) coupled to a thoracic cage, wherein the helmet component is a solid, unitary piece that surrounds the top, back, and sides of the user's head.
