Abstract: Mouth guards and related systems and methods for determining linear and angular accelerations of the head of a subject. A plurality of accelerometers are operatively associated with the mouth guard and spaced from one another about the mouth guard. The accelerometers produce outputs indicative of the linear and angular acceleration of the mouth guard. Optionally, the mouth guard can be used in conjunction with a helmet that is provided with a plurality of accelerometers spaced about the helmet. In use, the outputs of the accelerometers of the helmet can be correlated to the outputs of the accelerometers of the mouth guard.

Abstract: Mouth guards having electrodes, sensors, and/or accelerometers for determining one or more physiological conditions of a subject. Processing circuitry receives the outputs of the electrodes, sensors, and/or accelerometers. Optionally, at least a portion of the processing circuitry can be positioned within a helmet that is worn by a subject. The mouth guard can optionally be tethered to the helmet.

Abstract: Tap guide assembly devices, systems, and methods are disclosed herein. A tap guide assembly can have a body assembly, a tension pin assembly, a tension spring, and a setscrew. The body assembly can have an elongate body and a drill bushing. The drill bushing can have a diameter that is less than the diameter of the elongate body and can be positioned within a portion of the elongate body. The tension pin assembly can have a pin and a collar and can be configured to be received within the body assembly. The tension spring can be positioned proximate to the collar. The setscrew can be securely positioned proximate to the tension spring and within the second opening of the elongate body.
