The present invention relates to a power measuring device capable of obtaining accurate measurement values corresponding to changes in the state or environment of a target to be struck, and in variable striking conditions, such as being struck in a state in which movement of the target occurs, and the like. To this end, the present invention includes an air pocket group (11g) configured such that air pockets (11) are respectively formed in regions leading to a score according to striking in a target when the power measuring device (10) corresponding to variable striking conditions is installed on a target used in a fighting exercise; a piping tubes (12) formed to transmit pressure to a pressure sensor (13a) on the other side according to a change in volume on the air pocket (11) to increase the efficiency of score determination, by measuring a power at the time of strike by determining a strength (power) of the strike with an impulsive force applied to the air pocket (11); and a check valve (12a) formed in each piping tube (12) connecting each air pocket (11) at a front end of the pressure sensor (13a) to prevent air discharged when the air pocket (11) corresponding to a target point is struck from flowing to another air pocket (11) through the piping tube (12) connected to the pressure sensor (13a).

A brain injury reduction system provides a protective measure that temporarily or decreases venous drainage out of the intracranial compartment during or immediately before and during a sudden change in acceleration of an individual's head. Specifically, a wearable helmet or other wearable structure of the brain injury reduction system detects an impending collision and determines whether a protective measure is needed. If so, one or more actuation devices provides the protective measure to reduce venous drainage through one or both of the internal jugular veins or paravertebral venous plexus. A first actuation device stimulates a gag reflex or valsalva-like maneuver to reduce venous drainage through the paravertebral venous plexus. A second actuation device can physically compress the internal jugular veins. Thus, the brain injury reduction system minimizes the detrimental impact that may occur due to the sudden change in acceleration of the individual's head.

Systems, methods, and devices for protecting a user head are provided. In one example, a computer-implemented method can comprise receiving, by a system operatively coupled to a processor, a set of data detected by one or more sensor embedded within the helmet device. The computer-implemented method can also comprise adjusting, by the system, a pressure condition within a first set of inflatable cells of the helmet device based on the set of data.

The present invention is directed to an improved sports helmet including a quick release connector assembly for the faceguard that allows for rapid disconnection of the faceguard from the helmet shell. The connector includes a bracket, and a coupler mechanism featuring an elongated pin, a head component, a spring, a retractable engaging element and a washer. The connector assembly is moveable between a use position, wherein the faceguard is secured to the shell by the bracket and the coupler mechanism, and a released position wherein the bracket and the faceguard are disconnected from the shell. An inwardly directed actuation force that lacks a rotational component is applied to the elongated pin to move from the use position to the released position.

A helmet having non-bursting air cells preferably includes a hard helmet shell, an outside air cell impact layer and an inside air cell impact layer. The outside air cell impact layer preferably includes at least one air cell layer and an outside layer of sheet material. Each air cell layer includes a plurality of air cells created between two plastic sheets. The inside air cell impact layer includes the at least one air cell layer. The inside and outside air cell impact layers may be permanently or removably attached to hard helmet shell. A second embodiment of the helmet having non-bursting air cells preferably includes the hard helmet shell, the outside air cell impact layer and an inside air cell inflatable impact layer. The inside air cell inflatable impact layer preferably includes at least one inflatable air cell layer and a check valve.

An pressurized injectable mouthpiece for athletes. The invention is configured to be pressurized and injected to suit users that uses this type of equipment. The pressurized injectable is inserted into the users mouth pressure is applied by biting down on the unit the inside is then coated with fluid/supplements depending on the amount of pressure applied. The invention includes a open and closeable tab at the front of the housing of the unit. Suction vents/air pockets are also available.

A helmet includes interconnected flexing panels and a multi-chamber impact absorption system comprising a bladder including a plurality of adjacent compressible fluid filled chambers.

A helmet configured to protect a human head against mild traumatic brain injury upon impact includes an outer shell and a liner consisting of fluid fillable flexible fluid chambers fluidly connected to each other by fluid connections. The fluid chambers being spaced around the circumference of the helmet and configured to fill a space between the head and the outer shell when the helmet is positioned on the head. Impact resistant flexible pads are also in the liner and are spaced around an inner circumference of the outer shell adjacent to each of the fluid fillable flexible fluid chambers. A flexible inner shell inside the liner is configured to fit closely on the head. The flexible fluid chambers are configured to compress in response to impacting of the helmet on an impact side and to force liquids through the fluid connections to inflate other fluid chambers inside the helmet thereby cushioning the head against a rebound impact on the inside of the helmet.

There is disclosed an improved impact absorption padding for a contact sports helmet, for contact sports such as football, hockey and lacrosse, which incorporates a plurality of air pockets formed from a resiliently flexible material, such as plastic or rubber. At least some of the air pockets enclose a coil or spring. The coil or spring is also resiliently flexible over a wide range of temperatures, and oriented to compress in the general direction of impact to absorb a substantial portion of the energy before it is transferred to the head of the player. The coil or spring is also sized and shaped to return the air pocket to a desired thickness and shape after an impact. The air pockets may be arranged to substantially cover the outside of a contact sports helmet shell as a layer of impact absorption padding. A second inner layer of impact absorption padding may also be provided inside the contact sports helmet shell.

The disclosure provides neck collar devices and systems for the mitigation and prevention of traumatic brain injury, including concussion. Specifically disclosed are adjustable collars and systems, and collars having certain pressure sensing devices.
