An adjustable sports training system comprises a cylindrical shaft having a superior portion and an inferior portion, a goal structure mounted to the inferior portion of the shaft, the goal structure having a frontal region and a back surface. The goal structure further comprises a backboard with connected hoop on the frontal region, the hoop having an attached net, and the backboard has a back surface shared with that of the goal structure, a front surface, and an edge surface. The system further comprises a pivot mechanism mounted to the superior portion of the shaft, wherein the pivot mechanism has an interior region and the shaft runs centrally through the interior region of the pivot mechanism. The pivot mechanism is configured to precisely pivot the goal structure into locked rotational configurations.

A method can include providing an object having a size smaller than a size of a known regulation object, projecting the object, via a delivery device, toward a trainee, and training the trainee to follow the object. A method can include determining a game parameter of a game trajectory of a sports object that was projected along the game trajectory in a real-time sports event, and based on the game parameters, adapting a delivery device to deliver a training object along a training trajectory that mimics at least a portion of the game trajectory, with the training object being smaller than the sports object.

A method can include projecting an object toward an impact device along a trajectory, receiving the object at a target zone of the impact device, a trainee striking the impact device at an impact zone with a sports tool, and scoring a performance score of the trainee to impact the impact zone at an appropriate time compared to an arrival time of the object at the target zone. A method can include projecting an object toward a target along a trajectory, receiving the object at an actual arrival position at the target, wherein the actual arrival position is either inside a target zone or outside the target zone, and where a trainee is configured to send an indication when the trainee expects the object to arrive inside the target zone, comparing the indication to the actual arrival position, and determining a performance score based on the comparing.

The present disclosure relates to technology adapted for improved assessment of brain injuries in a human subject. For example, in some embodiments the invention relates to improved processing of data collected via an instrumented mouthguard device, including identification of false impacts. It will be appreciated that the invention is not limited to such a field of use, and is applicable in broader contexts. For example, the technology may be applied to detect other changes in physical performance, beyond head injuries. Furthermore, the technology may be applied in respect of other wearable devices which detect/measure head impacts, for example helmets.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

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.

The present disclosure provides sports apparatus including sports headwear and an impact detection arrangement for coupling to the sports headwear, e.g. a rugby scrum cap, to be worn by a user. The arrangement has a sensor for detecting an indication of an acceleration change experienced by the user's head when the sports headwear is being worn. The arrangement also has a visual indicator, e.g. an arrangement of LEDs, to provide a visual indication when the detected acceleration change exceeds a threshold. Advantageously, the present disclosure allows for immediate attention to be drawn to a player who has experienced a high g-force to their head, and therefore immediately alerts anyone in the vicinity that a medical check is needed to assess symptoms caused by the impact.

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.
