The present disclosure generally provides oral inserts useful for determining forces experienced by a user, such as a human user, to the head, for example, by measuring one or more of acceleration, velocity, displacement, or rotation. In some aspects, the disclosure provides oral inserts that, when worn properly by a human user, calculate the forces experienced by the user's head with high accuracy. In some aspects, the disclosure provides systems for detecting and calculating forces experienced by the user's head and to determine whether such forces are above a certain threshold indicative of increased concussion risk. In some aspects, the disclosure provides methods for calculating forces experienced by the user's head and determining whether such forces are above a certain threshold indicative of concussion.

A protective non-helmeted single molded facemask for sports includes a frame structure formed of a polycarbonate polymer that is structured and configured to engage a user's forehead, side and cheek facial structure and chin. An arrangement of vertical and horizontal bars in the central and lower portion of the face area of the facemask protect the users nose and mouth from direct contact with external objects, and particularly softballs, soccer balls, floor hockey sticks and pucks and field hockey sticks and balls. Upper and lower straps extend from slotted openings on the sides of the facemask and are positioned and arranged to extend around the lower back of the wearer's head to secure the facemask on the wearer's head. The facemask is designed to also significantly reduce the effective impact forces to the wearer's brain.

A system for reducing traumatic brain injuries in players on a sports field includes a number of transmitters worn by at least some of the players; a plurality of sensors configured for placement on or near the sports field for receiving signals transmitted from the transmitters as the players move about on the field; a head-stabilizing component worn by at least one of the players that inhibits relative motion of the player's head when activated; and a processing element coupled with the sensors and in communication with the head-stabilizing component. The processing element determines locations of the players based on the signals transmitted from the transmitters worn by the players, determines if the players are likely to impact one another or an object on the field based on the locations of the players, and transmits an activating signal to the head-stabilizing component to inhibit relative motion of the player's head if the processing element determines the player is likely to impact another player or an object on the sports field.

A latching device configured to secure a first piece of material to a second piece of material. For example, the first piece of material is a boat tarp and the second piece of material is a boat hull. The latching device includes a locking buckle and clasp assembly. The locking buckle has a main body portion and a release mechanism. The release mechanism has locking pawls with claw members. The locking pawls engage the clasp assembly to releasably retain the locking buckle on the clasp assembly.
