A portable target assembly for use in a sport wherein a projectile is propelled at a goal, the portable target assembly comprises a front face and rear face separated by a solid material, and a magnet secured to the portable target assembly allowing the portable target assembly to be magnetically attached to a goal post or crossbar. A magnetically receptive material is coupled to a goal post or crossbar when the post or crossbar is not made of a magnetic material. A method of sport training, comprising the steps of: providing a portable target assembly having a front face and a rear face separated by a solid material with a magnet secured thereto; securing the portable target assembly to a goal post or a cross bar of a goal such that the portable target assembly protrudes into a goal region of the goal; launching a projectile at the portable target assembly.

A practice target that includes: a front face; a rear face; a side face with a plurality of pockets, including first and second sets of pockets into which are disposed first and second sets of magnets. The first and second sets of magnets are identical in shape but are oriented opposite each other so that when the practice targets are stacked they have mutual attraction instead of being repelled by like magnets. The magnets include notches/cutouts/protrusions/etc. that match with similar structures in the pockets to hold them in place in the pockets. There are off-center pin holes through the magnets that make sure that they are oriented correctly during injection molding. There are netting grooves between the plurality of pockets and a tether aperture with a tether for attaching to a net.

Systems, methods, and computer-readable media are disclosed for autonomous tennis assistant systems that may automatically determine performance metrics and generate tennis statistics. Example methods include determining, by a device, various performance metrics for users via images captured during gameplay. For example, the device may determine whether a tennis ball landed within, outside, or on a boundary line, whether a point was scored, a ball speed of a tennis ball, topspin of a tennis ball, a type of stroke used to hit a tennis ball, whether a tennis match was won, hitting accuracy of a player, distance moved by a player, and/or other metrics. A base station may be used to provide image data for use by the tennis ball ejection robot from one or more additional vantage points.

An artificial turf for golf mimics visual and physical aspects of natural turf. The artificial turf includes a resilient, slow recovery, foam layer that temporarily deforms proximate to where the club head contacts the artificial turf during a swing, thereby allowing an uninterrupted swing arc with a descending angle of attack and forming a virtual divot cavity that mimics physical aspects of a natural turf divot. Trans-chromic synthetic grass blades on the surface of the artificial turf exhibit a temporary color change caused by contact with the club head during a swing, thereby forming a virtual divot cavity that mimics visual aspects of a natural turf divot. The slow recovery foam and trans-chromic grass blades enable analysis of the golf swing based on the virtual divot. The artificial turf may be incorporated into a practice mat.

A golf swing training device is disclosed that will provide instant feedback on the position of the golfer's clubface at impact. The device consists of a rebounding surface enclosed, and attach to a frame with a safety net, a goal, a golf mat to provide a hitting surface, and a ribbon attached from the bottom of the frame to the golf mat for alignment and shot analysis. The rebounding surface faces opposite the goal such that when a practice golf ball hits it, it will land in the goal if struck properly. Its angle may be adjustable to accommodate different clubs for a proper rebound into the goal. The rebounder surface may be made from a foam material with a fabric covering that when struck, leaves an indention for visual target reference, repels the ball, and indicates ball spin by referencing where the ball landed inside or outside the goal.

A system for swing training with a bat, the system includes a training device, having a bat spacer attached to a sweet spot position on the bat about a barrel portion of the bat, the bat spacer having a body with a top surface and a bottom surface; the bottom surface is contoured to snugly fit against an outer surface of the barrel portion; the bottom surface is secured against the outer surface via an adhesion material; and the bottom surface wraps partially around the outer surface; a flexible energy absorbing cover attached to the top surface of the bat spacer, the flexible energy absorbing cover having an interior cavity; an electronic faceplate secured within the interior cavity to sense data associated with the bat coming into contact with a ball; and an electronic device in wireless communication with the electronic faceplate; the electronic device is to record data sensed.

A goalie training apparatus comprised of multiple catchment voids for receiving balls. Catchment voids are oriented on a grid, and connected to a goal frame by a support matrix. Each catchment void is pyramidal in shape, having an open base for receiving a ball with an initial cross sectional area and tapering to a smaller cross sectional area. The support matrix may be woven through internal sleeves in the catchment voids and connected to the goal frame by fasteners. An anchor support may be used to help anchor the support matrix and keep the goalie training apparatus in place across the opening of a goal during use.
