In one aspect, a shroud assembly for headgear includes a frame having a shape that matches a contour of the headgear. An insert is formed of metal or metal alloy and is attached to a front side of the frame. The insert is configured for removable attachment to a mounting assembly. The frame includes first and second spaced flexible walls disposed on the front side of the frame on opposite sides of the insert. The first and second flexible walls are spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second flexible walls. In another embodiment, the shroud assembly further includes a friction pad disposed on a rear surface of the frame for increasing friction between the shroud assembly and the headgear. In another aspect, a method for attaching a mounting assembly to headgear is provided.

A force attenuating helmet construction including a rigid layer generally conforming to the wearer's head. A plurality of force absorbing and reacting portions extend from locations of the rigid layer such that, in response to an impact event experienced by the helmet, the absorptive and reactive forces minimize impact forces transferred to the user's head and spine. The helmet can include inner and outer rigid layers, or shells, and which are spatially supported by a plurality of force attenuating components. A dual compression coil is associated with each of opposite end mounting portions of a face mask with the outer shell for providing for bi-directional force absorbing displacement of the mask portion.

Embodiments include methods, systems and computer program products for monitoring a user of a helmet for traumatic brain injury. Aspects include obtaining a saliva specimen from a mouthguard and providing the saliva specimen to a lab on chip. Aspects further include determining whether the saliva specimen contains a biomarker that indicates the user suffered a traumatic brain injury and creating an alert that the user of the helmet has suffered a traumatic brain injury.

The invention includes a protective headpiece and components thereof and methods for their use. Preferred examples comprise a helmet component, a plurality of piers joining said helmet component to a shoulder pad component and an inner hat component permitting the wearer the ability to move the head from side to side and/or up and down within the helmet component without moving the helmet component. The helmet component may comprise a plurality of fluid-filled floating plates or floats on the inner surface thereof to cushion the head against impact during activities including, for example, football, race car driving, military activities and the like.

A protective helmet includes a plurality of fluid filled bladders, impact sensors, valves, and pumps wherein the helmet absorbs energy from an impact to protect a person wearing the helmet from traumatic brain injury. The bladders expel fluid in response to a triggering event such as energy from an impact detected as a pressure spike event and/or detected as an acceleration event. A selected bladder may expel fluid to other bladders, to a reservoir, to the environment outside of the protective helmet, or combinations thereof. In embodiments where the bladders need additional fluid after an impact, one or more pumps may refill selected deflated bladders. When a bladder is underinflated, an indicator light may emit light on an outer surface of the protective helmet to warn that the bladder is not yet ready to be placed in operation to absorb another impact.

A helmet mount system for attaching a device to a helmet comprises a threaded interface assembly having an outer portion and a threaded insert received within a cavity formed in the outer portion. The outer portion has an inward facing surface configured to receive an adhesive layer for coupling the inward facing surface to a surface of the helmet. In a further aspect, a ballistic helmet having the helmet mount system herein is provided, wherein the helmet mount system does not penetrate a ballistic layer of the ballistic shell.

A modular helmet interface with a mounting cleat, threaded insert, and adhesive layer is provided. In one aspect, a mounting cleat is affixed to a helmet, such as a ballistic helmet, by an adhesive layer, the mounting cleat having an outer portion and a threaded insert within a cavity formed in the outer portion. The outer portion has an inward facing surface configured to receive an adhesive layer for coupling the inward facing surface to the helmet surface. In another aspect, a mounting cleat is secured to a helmet by way of a cleat-receiving securing member, the securing member affixed to the helmet by an adhesive layer. In a more limited aspect, a helmet having multiple mounting cleats configured to support an accessory mounting rail or a helmet mount assembly.
