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.

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.

An apparatus for preventing neck injury, spinal cord injury and concussion is disclosed. The apparatus includes a helmet, a body harness and a plurality of anchor assemblies connecting the helmet to the body harness. The anchor assemblies are adjusted to limit the cervical rotation, lateral bending, flexion and extension ranges of motion of a wearer to a predetermined set point, each anchor assembly including a plurality of guide members extending from the helmet to an anchor of the anchor assembly, the plurality of guide members being attached to the anchor.

A system includes a first device, a second device, and garment. The garment has an elastic region that is configured to receive the first and second devices so that, when the garment is worn by a subject, the first and second devices are positioned at a respective one of a pair of neck veins of the subject. The first and second devices and/or the elastic region apply a compressive pressure to the pair of neck veins while the garment is worn.

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.

An uncoupled anterior cranial shield is disclosed including a yoke configured to attach to support garment or integrated with the support garment and a suspended mask attached to the yoke and extending from the yoke so as to be disposed at least partially covering a face of an individual wearing the support garment. The suspended mask is free of force communicating persistent connection to a head of the wearer other than indirectly through the shoulder pads.

Protective equipment used in a wide range of sports occupations and other activities and occupations to prevent concussions and other injuries that may absorb shock or force brought on by the kinetic energy from flying objects such as a ball, bat or other moving object. Such protective equipment assembly comprising a wearable assembly and a facemask. The wearable assembly may comprise a chest panel and a pair of shoulder anchors. A chest attachment mechanism may be provided on the chest panel and a shoulder attachment mechanism may be provided on the shoulder anchors. The facemask may be secured to the wearable assembly via the chest attachment mechanism and the shoulder attachment mechanism such that the facemask is not in contact with a neck or a head of a user.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A head and neck orientation retainer block for training young or adult athletes for their sport while keeping their head up to provide a safer way to play, and also to enhance their skill and vision of the game. It can be worn during practices with the team and if one chooses, to practice at home. The retainer is a wedge block protrusion placed under the central forward chin of the child or adult player, to allow the player to have a wider freedom of side to side lateral movement, while the player's head is maintained horizontally for line of sight viewing purposes.

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.
