Abstract: Systems and methods for monitoring head-accelerations data for a plurality of athletes. An exemplary system includes a plurality of athlete-mounted sensor units that record acceleration information and wirelessly transmit the recorded acceleration information and information identifying the sensor unit, if the recorded acceleration information exceeds a predefined threshold. A base unit receives the wirelessly transmitted acceleration information and the information identifying the sensor unit and makes the received information available to at least one output device.

Abstract: A mouth guard having a proximity sensor, an impact sensor, a processor in signal communication with the sensor, a memory in data communication with the processor, a transmitter in signal communication with the processor, and a battery. The processor is configured to allow data transmission the mouth guard has been inserted into a mouth. The processor is also configured to instruct the transmitter to transmit a signal if an impact above a predefined first threshold is sensed.

Abstract: A method for producing a mouth guard having an encapsulated sensor module. The method includes vacuum forming a first sheet of thermoplastic material using a mold to produce a first mouth guard layer, attaching a sensor module to the first mouth guard layer with a hot melt adhesive, vacuum forming a second sheet of thermoplastic material over the sensor module to produce a second mouth guard layer, storing a default threshold level in the sensor module, and calibrating the sensor module to account for sensor alignment. In an example embodiment, the first and second layers are formed such that they define an open area that allows a user's tongue to touch their upper palate after the mouth guard has been inserted and such that the layers define a channel for accepting a plurality of teeth, including the incisors of a user.
