A pneumatic ball launcher includes a tube, a ball pathway unit, a push unit, a holding unit, an airway unit and a pneumatic unit. The ball pathway unit is used for connecting one end of the tube and wrapping part of a ball channel of the tube. The push unit includes a push bar, a slide base, a first driver and a second driver. The holding unit, detachably connected with the push unit, is used for holding the ball pushed by the push bar. The airway unit is connected with the holding unit. The pneumatic unit includes a valve mechanism, a pneumatic cylinder and a gas tank. When the valve mechanism opens to allow the gas tank to discharge into the holding unit via the airway unit, the ball held by the holding unit would be ejected out of the tube.

A sports implement includes a main body portion, a handle portion extending from the main body portion, and a grip member. The main body portion includes a first contact surface, a second contact surface, and a sidewall positioned about a perimeter of each of the first and the second contact surfaces. The handle portion defines a handle central axis extending therethrough. The grip member includes a grip body portion and a grip end portion. The grip body portion is operably coupled with the handle portion. The grip end portion defines a grip central axis extending therethrough. The handle central axis is offset from and parallel to the grip central axis.

A method can include determining physical characteristics of a trainee, adjusting a target zone based on the physical characteristics, adjusting one or more parameters of a delivery device based on the physical characteristics, projecting an object toward the target zone along a trajectory, and scoring a performance score of the trainee to track the object along a portion of the trajectory. A method can include projecting an object toward a target zone along a trajectory, a trainee attempting to impact the object at an appropriate location with a desired impact location of a sport tool, capturing imagery that contains the object at the appropriate location and the desired impact location of the sport tool, determining horizontal and vertical distances between the desired impact location and the object arriving at the appropriate location, and scoring a performance based on the horizontal and vertical distances.

A method can include projecting one or more objects along one or more pre-determined trajectories toward a target zone, with each having a diameter less than a diameter of a regulation table tennis ball, the trainee attempting to prevent the one or more objects from entering the target zone and scoring the ability of the trainee. A method can include displaying a first video to a trainee that explains setup for a delivery device, setting up the delivery device based on the first video, projecting an object along a pre-determined trajectory toward a target zone proximate the trainee, wherein the object has a diameter that is less than a diameter of a regulation table tennis ball, and scoring an ability of the trainee to interact with the object at the target zone.

The present invention relates to a ball picking robot, comprising a walking mechanism, a ball picking mechanism, a ball pushing mechanism and a ball storage mechanism. The ball picking mechanism comprises a ball picking basket, an air cylinder used for driving the ball picking basket to move up and down, an air storage tank used for providing an air source for the air cylinder, a solenoid valve arranged at the air outlet of the air storage tank, a micro air pump connected to the air storage tank, and a shielding assembly arranged at an opening in the rear end of the ball picking basket. A first gear is mounted at the input end of the micro air pump. The ball pushing mechanism comprises a rotary ball discharging assembly, comprising an either-rotation motor, a rotary impeller connected to a first output shaft of the either-rotation motor through a belt assembly.

A table tennis apparatus including a table top made out of a fiberglass reinforced structural material (FRSM). The table tennis apparatus includes a pair of tables. Each table includes a table top having a three-layered composite panel made up of FRSM. The table top receives aluminum plates at its sides. Further, the table top receives mounting brackets at its bottom surface. The mounting brackets include male members that extend perpendicularly to the mounting brackets and fold over the mounting brackets. The table top rests at a height from the ground and allows its top surface to act as a playing surface for playing table tennis.

Provided is an analysis apparatus including an acquisition unit that acquires vibration data showing a vibration generated in a first object by having a second object come into contact with a first position on the first object, a first analysis processing unit that specifies the first position by comparing a vibration characteristic shown by the vibration data, and a vibration characteristic defined for each position where the second object may come into contact with the first object, and a second analysis processing unit that estimates a velocity after the contact of the second object based on a velocity of the first object and the first position.

A piece of sports equipment includes a handle, a head attached to the handle, and at least one dead blow mechanism. The at least one dead blow mechanism includes a chamber and a movable portion disposed within the chamber. The chamber and the movable portion each include a similar cross sectional shape.

A collapsible net for a game play is disclosed. The collapsible net includes a plurality of net-modules, each of the plurality of net-modules including a first-type coupler adjoining a left-side edge and a second-type coupler adjoining a right-side edge of each of the plurality of net-modules. The first-type coupler is configured to engage with the second-type coupler to couple the net-modules with one another, to thereby define an expanded length of the collapsible net.

An illuminated paddle includes a frame comprising a paddle portion, a handle portion extending from the paddle portion, a perimeter that extends around the paddle portion and the handle portion, and a channel positioned along at least a portion of the perimeter, the paddle portion comprising a plurality of internal strength members that define a plurality of cavities, a light source assembly disposed at an end of the handle portion, the light source assembly comprising at least one light source, and a light pipe disposed within at least a portion of the channel of the frame, the light pipe is optically coupled to the at least one light source.
