A shuttlecock loading mechanism with a grabbing mechanism and a pair of ejecting wheels defining a wheel plane. The grabbing mechanism receives a shuttlecock entering the loading mechanism in a vertical position and ejects the shuttlecock from the loading mechanism in an orientation parallel to the wheel plane wherein the pitch of the wheel plane about a wheel horizontal axis is selectively indexed about the wheel's horizontal axis.

Invented adjustable and portable wrist power exercising rod is a portable exercising equipment that is used for exercise all the wrist movement related muscles and griping strength. It possesses two exercising modes: waving-mode for exercising muscles for forearm pronation, supination, flexion, and abduction and twisting-mode for exercising hand griping and wrist bending. It also features exercising strength adjustability for different individuals to exercise at their levels.

Embodiments disclosed provide a solution to detect a rally in a sports game. One or more stroke actions or non-stroke actions are detected based on motion data detected by a sensor attached to a sports instrument of a user. Using a trained stroke classification model, each detected stroke action is classified into a plurality of classes. Additionally, a determination is made whether each detected non-stroke action is an intentional special user action. The determination whether a non-stroke action is an intentional special user action is made based on a customized set of definitions defining one or more special user actions. One or more rallies are then detected based on the classified stroke actions and intentional special user actions.

A sporting apparatus includes a monitoring device. The monitoring device may add no weight to the sporting apparatus relative to a comparable sporting apparatus without the monitoring device. The monitoring device may have a center of gravity substantially aligning with the center of gravity of the sporting apparatus, resulting in a sporting apparatus with a monitor having substantially the same center of gravity as a comparable sporting apparatus without a monitor. The sporting apparatus monitor may be configured to trim unreliable post impact swing data and replace it with extrapolated pre-impact swing data and/or more reliable post impact swing data.

A device to function as a training aid designed to improve the tennis serves, ground strokes and volleys, badminton serves and strokes, volley ball serves and returns, baseball batting, racquet ball serves and returns, and squash serves and returns. It is also useful in any activity where the user seeks to improve striking performance when a sports object is suspended in a particular three-dimensional space location.

A retractable recreational net system includes a first self-supporting pole arrangement mountable on a ground surface; the first pole arrangement having a first net storage reel; a second self-supporting pole arrangement mountable on the ground surface; the second pole arrangement having a second net storage reel; a net selectively extendable between the first pole arrangement and the second pole arrangement; and at least one retraction mechanism to selectively retract the net onto at least one of the first net storage reel or second net storage reel.

A swinging assist device may include a hand securement and a strip coupled to the hand securement. The strip can form an elongate grip portion. The strip can include a first layer having a first end and a second end, a second layer having a first end and a second end. The second layer can be configured to contact a sport equipment in use. The swinging assist device may include a fastening system including a first fastening feature and a second fastening feature. The hand securement can be configured to receive the first hand of a user and the elongate grip portion can be configured to receive the second hand of the user. The swinging assist device can be configured to enable the user to freely release the second hand from the grip portion.

An electronic apparatus includes a presentation portion that presents a ratio between a length of a trajectory of a predetermined portion of an exercise equipment and a length of a portion of the trajectory included in a predetermined region in a predetermined period of a swing, or presents a ratio between the predetermined period of the swing and time for which the predetermined portion of the exercise equipment is included in the predetermined region in the predetermined period.

Provided is a sensor device including a sensor configured to output a vibration datum by detecting a change in a state of a vibration in a first object when a second object touches the first object, a holding section configured to hold, at a portion of the first object which is different from a portion where the second object touches, the sensor in a state where the vibration in the first object is transmitted, and a communication section configured to transmit the single vibration datum detected by the sensor to an analyzing device which identifies a touch position where the second object touches the first object by analyzing the vibration datum.

CourtAI introduces an innovative approach to overcome several limitations associated with traditional coaching methods. Leveraging AI technology, the system meticulously analyzes player movement patterns, speed, and gameplay actions to formulate personalized game strategies and pinpoint areas for improvement. Advanced tracking software is integrated to observe the ball, racket, and player's movements, speed, and posture, providing immediate feedback for on-the-spot performance assessment during practice. Additionally, the system curates personalized training agendas and dynamically adjusts them based on real-time player performance. It enhances the training experience by delivering voice feedback, creating a more engaging learning environment. Moreover, CourtAI implements mechanisms to proactively address potential injuries by closely monitoring player actions.
