Methods, systems, and techniques for automated detection of goals and announcement of same are provided. The system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and, when an infrared signal is received, the microcontroller automatically triggers one or more annunciator devices, such as visual, auditory, or haptic devices, to automatically indicate that a goal has been scored without human intervention.

A sporting implement, such as a blade for a hockey stick, may include an outer layer, a core, and a recovery gel positioned between the core and the outer layer. The recovery gel can form a film, be compressible, shape recoverable, and pressurized to a predetermined pressure. The recovery gel can be configured to provide an integrated agent for filling cracks that appear during use of the blade and configured to absorb energy impacts between the outer layer and the core. When a crack appears, the predetermined pressure can be relieved inside the crack and fills a cavity formed by the crack to provide cohesion between the outer layer and the core to recreate a new material in the place of the crack. The recovery gel can be configured to help prevent cracks from propagating and actively heals potential damages by reducing stiffness loss caused by cracks.

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 treadmill may include a platform, at least one pulley attached to the platform, a sliding surface of the platform, a tread belt riding portion of the sliding surface, a tread belt surrounding the pulley and the sliding surface, the tread belt having at least one side edge, and a belt guide incorporated into the platform. The belt guide includes a textured portion of the sliding surface aligned with the side edge of the tread belt and spaced apart therefrom when the tread belt is positioned entirely within the tread belt riding portion. When the textured portion comes into contact the tread belt from the tread belt being misaligned out of the tread belt riding portion, the tread belt and the textured portion collectively produce a misalignment sound audible to a user when the tread belt moves against the sliding surface.

A support shirt comprising a shirt body and a pair of shirt body sleeves positioned adjacent to an upper shirt body is provided. The sleeves are attached to the shirt body at sleeve body holes, with each of the sleeves including sleeve reinforcement regions extending at least a portion of the distance from the sleeve holes to an outer edge of the sleeves. The sleeve reinforcement regions extend substantially along a centerline extending longitudinally across the sleeves and the upper sleeve body to stabilize and provide support to the shoulders of a wearer during an upward lifting motion.

An exercise machine is disclosed. The exercise machine comprises a tension generating device. The exercise machine comprises a translatable arm mount coupled to the tension generating device. The exercise machine comprises an arm coupled to the translatable arm mount. The exercise machine comprises a cable coupled to the tension generating device via the arm.

A sports projectile delivery system may control the operation of a launcher to cause an American football or other sports projectile to be delivered to a target location on a field. In some aspects, the system can track player movements on the field, e.g., through the use of a tracking device mounted on the player, enabling the ball etc. to be launched to a player in anticipation of where the player will go. The system may include additional customization and/or logging options, e.g., permitting a player to designate a body position (e.g., above the head or near the knees) for delivery of the ball, designate a speed or hang time for delivery, or provide player data and analytics to an online or otherwise connected database.
