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 personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

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 pad for protective equipment is provided, the pad includes a foam layer having a generally cantilever shape with an inner face and an outer face opposite the inner side, a top and a bottom opposite the top, and a medial end and a lateral end opposite the medial end, wherein at least one of the inner face and the outer face includes at least one vertical depression extending between at least a portion of the top bottom and the bottom of the foam layer, and extending through to the bottom of the foam layer, the foam layer further having at least one a slotted aperture therein extending through the inner face and the outer face, the at least one depression interesting with the at least one slotted aperture.

Aspects herein relate to a shoulder-pad system that may be used to attenuate impact in various contexts. The shoulder-pad system may have a number of subcomponents, which may include an impact plate assembly, an impact-attenuation sub-layer, a base-layer garment, and a securing garment, among others. The shoulder-pad system may be described as modular, in that the various subcomponents may be added to, and/or removed from the system when it is desirable to do so.

The present disclosure relates to systems and methods for manufacturing a mouthpiece with desired dimensions or thicknesses that may enhance the performance of an individual when participating in a contact sport. Mouthpieces and methods consistent with the present disclosure may include incremental steps of three dimensional printing that use different materials. Dimensions and materials used when manufacturing mouthpieces of the present disclosure may be optimized according to user preferences or settings.

A system, method, and blocking pad for receiving strikes from a special individual. The blocking pad includes a pad configured to receive the blows from the special individual. The blocking pad further includes a number of handles connected to a back of the pad. The number of handles include at least two handles in a middle portion of the back of the pad and at least a handle at ends of the pad.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

An oral appliance for treating sleep apnea in a user includes a mouthpiece configured for being positioned in an oral cavity of the user, and at least one pulse oximeter attached to the mouthpiece. According to an aspect, the pulse oximeter is configured to monitor actual oxygen saturation levels of hemoglobin of the user when the oral appliance is positioned in the oral cavity of the user. The oral appliance may include an additional sensor attached to the mouthpiece that includes at least one of an airflow sensor, a pressure sensor, a noise detector, and an actigraphy sensor.
