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.

A sweat absorbing device includes at least one first strip which has a connection end, and the connection end is connected to a portion of the at least one first strip to form the at least one first strip as a loop. The at least one first strip is removably connected to the handlebar. A sweat absorbing pad has a top face for absorbing sweat, and a bottom face. The at least one first strip is removably connected to the bottom face of the sweat absorbing pad. The sweat absorbing pad can be adjusted relative to the stationary bike so as to properly absorb the rider's sweat.

A weight plate gap adjustment module for weight training equipment includes an elastic member located at the topmost weight plate of the weight training equipment and having a supporting portion arranged on the weight plate adjacent to the topmost weight plate, and an adjustment member set on the topmost weight plate and movable toward the elastic member to increase the elastic force of the elastic member, so that when the elastic force of the elastic member is greater than the total weight of the topmost weight plate and the traction shaft, the elastic force of the elastic member drives the elastic member to push the topmost weight plate and the traction shaft to move relative to the other weight plates, allowing the locking pin to be selectively inserted through one weight plate and the traction shaft and joined to the traction shaft.

A trampoline has a side frame supported by support legs, multiple fiberglass guardrail poles joined to the side frame or the support legs, and a guardrail netting held open by the guardrail poles. Each guardrail pole includes two fiberglass rods joined together by a connector that includes two nested securing tubes, where two respective ends of the two fiberglass rods are inserted in the internal securing tube. The external securing tube is secured outside of the internal securing tube. The guardrail netting has multiple securing fabric sleeves stitched to its top end. Each sleeve has a first part with a sealed top and a width matching that of a wider top section of the fiberglass guardrail pole, and a second part connected to the first part with a width matching that of the fiberglass guardrail pole, where the second part has a gap in the middle.

An exercise machine comprises a tension generating device, a translatable arm mount coupled to the tension generating device, an arm coupled to the translatable arm mount, and a cable coupled to the tension generating device via the arm.

The two-part 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 triggers the light sources mounted to the goal to illuminate and indicate that a goal has been scored. Additionally, both the puck and the goal units are designed to reduce power consumption by switching between a low-energy mode or an active mode of operation.

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.

A barbell includes a rotational body including a bar, a sleeve assembly having a sleeve with a bore, where a portion of the bar is received through the axial bore, a proximal bushing received in the bore and having a passage receiving the bar, a distal bushing received the bore and having a cavity receiving a portion of the rotational body. The proximal bushing has a first outer surface engaging the sleeve and a first inner surface engaging the bar within the passage. The distal bushing has a second outer surface engaging the sleeve and a second inner surface engaging the portion of the rotational body within the cavity. The proximal bushing and the distal bushing permit the sleeve assembly to rotate around the rotational body, and at least one of the first inner and outer surfaces and at least one of the second inner and outer surfaces are polymer surfaces.

A weight plate gap adjustment module for weight training equipment includes an elastic member located at the topmost weight plate of the weight training equipment and having a supporting portion arranged on the weight plate adjacent to the topmost weight plate, and an adjustment member set on the topmost weight plate and movable toward the elastic member to increase the elastic force of the elastic member, so that when the elastic force of the elastic member is greater than the total weight of the topmost weight plate and the traction shaft, the elastic force of the elastic member drives the elastic member to push the topmost weight plate and the traction shaft to move relative to the other weight plates, allowing the locking pin to be selectively inserted through one weight plate and the traction shaft and joined to the traction shaft.

Systems and methods for adjusting resistance on an exercise apparatus include a first resistance apparatus having an adjusting bracket, magnetic members mounted on an inner surface of the adjusting bracket, a stepper motor having an adjusting shaft and operable to traverse a portion of the length of the adjusting shaft. At a first position, the magnetic members are disposed above a flywheel, and in a second position, the magnetic members are disposed on opposite sides of the flywheel, providing resistance thereto. A load cell couples the adjusting bracket to the frame and generates a signal corresponding to the movement of the adjusting bracket. A computing system calculates resistance, rpms, power from load cell signal, stepper motor position, shaft rotational position and other sensor inputs.
