Apparatus, systems, and methods are provided for the reduction of head or neck trauma in a living being by mitigating the acceleration experienced by the head, relative to the torso, during a change in motion; for example, creating a neck support that provides improved extension, compression, rotation, and bending properties to the neck in order to control the acceleration experienced by the head. The apparatus can be configured to create a neck support in which acceleration of the head, relative to the torso, is reduced with minimal structure, discomfort, and other potential downsides to the user of the apparatus.

The Concussion Reduction Prevention System is a protective helmet and shoulder pad device that may be worn by an athlete, such as a football player, during sports play to reduce the likelihood that the athlete will obtain a concussion. The helmet is large enough to allow the athlete's head to move freely within it. The helmet connects to the pad via a cradle. The cradle includes attachment points along the athlete's shoulders so that impact forces are distributed onto the athlete's shoulders. The pad is reinforced to distribute impact forces from the helmet to the athlete's shoulders.

An arm and chest exerciser includes elastic cuffs into which a user places the upper arms. An elastic chest band connects the cuffs. Moving the user's arms backwardly stretches the chest band and exercises muscles of the arms, chest and shoulder. A gripping handle connects to the chest band adjacent to a midpoint allowing the user or spotter to pull down on the chest band and appropriately position it on the user's chest.

A method and device for reducing the damaging effects of radiant energy, blast, or concussive events includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during or before the incidence of the imparting event. Reducing blood outflow from the cranial cavity increases intracranial volume and/or pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood outflow further increases the intracranial pressure and volume, and thereby increases the pressure and volume of the cochlear fluid, the vitreous humor and the cerebrospinal fluid to thereby reduce the risk of injury to the inner ear, internal structure of the eye and of the spinal column. In addition, increasing intracranial pressure and volume reduces the likelihood of brain injury and any associated loss of olfactory function.

A neck gaiter system configured to be received on the neck of a wearer that includes a gaiter member that includes a neck portion and a clavicle portion, a sensor system that includes at least one gyro sensor positioned on the gaiter member, an actuation system in electrical communication with the sensor system, and a bladder positioned on at least the neck portion of the gaiter member. The bladder is in fluid communication with the actuation system. When the sensor system senses a predetermined rotational change, the actuation system inflates the bladder.

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.

Disclosed herein are wearable articles and methods for the manufacture and use thereof. The wearable articles can comprise compression elements, gripping elements, and support elements containing a rate-sensitive material which can operate to prevent injury.

An improved head protection helmet assembly includes a helmet and a torso subassembly that is either a support vest or a shoulder pad subassembly. The helmet and torso subassembly are attached together in a way the helmet cannot move relative to the torso subassembly. A force applied to the helmet is transferred to the torso subassembly. The head of a person using the head protection helmet assembly can be moved inside, and relative to, the helmet. The head protection helmet assembly can also include front and rear body plates attached to the torso subassembly to reduce movement of the torso subassembly and the helmet.

A protective helmet attachment connects a helmet to a set of shoulder pads. The attachment includes a set of links that are attached to the helmet, and are adapted to ride within an annular track situated around the head opening in the shoulder pads. The links redistribute the force from a blow to the head down to the shoulders and body. The links may be of one piece that is rigidly attached to the helmet, thus providing maximum protection. Alternatively, the links may be formed of two pieces that are pivotally connected using a shoulder bolt, thus somewhat reducing the level of protection afforded against a blow to the front or back of the head but maintaining the ability to tilt the head.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.
