A hockey puck (1) comprising an accelerometer (101) arranged in a recess (5) of a puck body (3). The accelerometer (101) is configured to measure the acceleration of the hockey puck (1) in at least one direction in x-y-z coordinates. The hockey puck further comprises a power supply (25) and a control unit (109) configured to read sensor input from the accelerometer (101) and to provide a control unit output based on said sensor input.

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 combat sports scoring system according to an embodiment of the present disclosure includes a striking object performing a striking action, a striking target including a scoring portion which is hit by the striking action, a control part configured to determine a valid hit and calculate a score on the basis of a hit signal output by the striking object and calculate a score, wherein the striking object includes a hit determination device configured to transmit the hit signal including information about the striking action to the control part.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A martial arts training system comprising: (a) one or more hand held targets; (b) one or more wearable devices; and (c) trainee log-in hardware installed in said target(s) and said wearable device(s).

Disclosed is a putting practice device configured to enable training of keeping a putter face square without checking movement of a golf ball, to enable training of controlling putting strength as well as keeping the putter face square, and to enable training of practicing linear motion of a putter during execution of a putting stroke while an actual golf ball is struck. The putting practice device for the training of keeping the putter face square and controlling the putting strength includes an advance groove, a base plate, a striking part, an impact sensor, and a display part.

A system is disclosed that includes a ball-throwing machine included within a first housing, a controller communicatively coupled to the ball-throwing machine and included within a second housing different than the first housing, a camera, and a non-transitory storage medium having stored thereon logic, the logic being executable by one or more processors to perform operations including: receiving information associated with a selection of a first training drill from the controller, responsive to receiving the information associated with the selection of the first training drill, causing the ball-throwing machine to impart motion to one or more balls in accordance with the first training drill, receiving multimedia data of a player captured by the camera, and performing a player recognition procedure to locate the player within the multimedia data.

Technology is adapted to facilitate user-specific calibration of instrumented mouthguard devices, including calibration methods for instrumented mouthguard devices. For example, this includes processes by which instrumented mouthguards, which include components such as accelerometer modules that enable monitoring of head movements of a mouthguard wearer, are calibrated for use by specific individuals. While some embodiments will be described herein with particular reference to those applications, it will be appreciated that the present disclosure is not limited to such a field of use, and is applicable in broader contexts.

A method for prediction of a head impact event mechanism via an instrumented mouthguard device comprises receiving, as input, time series data representative of a head impact event, wherein the time series data is derived from the instrumented mouthguard device. The instrumented mouthguard device includes one or more accelerometers. The method further comprises generating an array of spatial coordinates representing points on a computer head model, and processing the time series data to determine a direction of impact and location of impact relative to the computer head model.

The present disclosure relates to systems, devices, and methods for measuring physical impacts to various surfaces, including athletic equipment such as punching bags, tackling dummies, etc. An example system includes a punching bag and a plurality of force sensors coupled to the punching bag. The force sensors are configured to detect physical impacts on the punching bag.
