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 sensor coupled to a processor; and a transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

Method and apparatus for improved helmet having an outer shell with a face mask disposed thereon along with an inner shell so that the outer shell floats without the inner and outer shells separating while maintaining an air gap between the inner shell and the head of a user which prevents direct contact between the helmet and the head or neck of a user. An outer collar closely surrounds the sides and back of the outer shell and is attached to the shoulder pads preventing direct impact to the rear of the outer shell and also much of the area behind the ear of a user. Gel pads are placed between the two helmet shells and the top of the helmet collar and between the shoulder, chest and back pads and the body of the user. A head and neck restraint and third-party neck brace are also shown.

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.

A system for reducing trauma in the head or neck of a living being caused by acceleration of the head relative to a torso of the living being within a range of motion. The system includes a support engaging at least one of the head, neck, and shoulder of the living being without limiting the range of motion of the head or neck relative to the torso; a sensor in electrical communication with the system; a user interface in electrical communication with the sensor; and a damper associated with the support that is configured to mitigate the position, speed or acceleration of the head relative to the torso in response to information received by the sensor or user interface.

A head and neck support and restraint system including protective headwear worn by a user; an article worn about the shoulders, chest and back of the user; and a dynamic connector that is disposed between and attached to the protective headwear and the worn article that dampens and distributes forces to which the head and neck are subjected during use. Such forces can include forces experienced as a result of acceleration, deceleration, or impact during a collision between the user and another person or object. The dynamic connector also supports and limits the rate and range of motion permitted between the head and neck relative to the shoulders, chest and back of a user when the head or body of the user is subjected to such forces.
