Abstract: A smart portable golf dispenser comprises a golf ball container, a golf ball regulator, a rotary switch plate, a ball release box, three height-adjustable feet, and a golf ball control system. Golf balls run from the golf ball container into the golf ball regulator, where they are regulated and prepared to be dropped to the ball release box. A golf ball is released from the ball release box following a confirmed ball strike, determined by the combination of swing motion and ball strike sound. Each golf swing is recorded on video and can be played back in slow motion on a smart phone. The speed of each ball strike is calculated. Golf swing videos and ball strike data are stored in a smart phone through a smart phone APP. Three height-adjustable feet can automatically adjust to make the smart portable golf ball dispenser leveled.

Abstract: A golf putter includes a putter head and a shaft. The putter head includes a toe end and a heel end, a putter face, a first part, a pair of connecting pins, and a second part. The second part is coupled to the first part via the pair of connecting pins such that the putter head defines a center of gravity of the putter head in a plane that is parallel to a vertical plane containing the putter face and that passes through the pair of connecting pins. Further, a bottom end of the shaft is coupled to the second part of the putter head at a contact point that lies between the toe end and the heel end of the putter head and that lies behind the center of gravity with reference to the putter face, and a top end of the shaft is inclined towards the vertical plane.

Abstract: Synergistic pairings of golf club and golf ball is important to achieve the maximum performance. The golf club and golf ball, although often designed in vacuum, can benefit from a synergistic design concept that base the design of one component based on the design of the other design. In one example, a golf ball may have a lower launch angle, lower spin generation, higher drag, and/or moderate to relatively lower net lift, which can be paired with a club head that generates a higher launch by having a laser-generated features that increases the surface roughness to create a higher launch and/or spin that creates contrast on the club face of the golf club head. The laser-generated features increase the surface roughness value of the external surface of the club face by imparting micro-grooves that have an average groove depths of between about 45 ?m and about 60 ?m.

Abstract: A basketball goal including a lower pole, an upper pole, a backboard and a rim. The lower pole extends from a base and extends with a lower pole hinge adjacent one end of the lower pole. The upper pole includes an upper pole hinge, the upper pole hinge configured to be coupled to the lower pole hinge with a pin to facilitate pivotably coupling the upper pole to the lower pole. The backboard is configured to be coupled to the upper pole, and the rim is configured to be coupled to the backboard. The pivotable coupling between the lower and upper poles is for assisting assembly of the basketball goal with an assembly system such that, upon assembling the basketball goal, the upper pole is fixated in an upright position with the lower pole. Also, a light pole may be assembled with a hinged coupling, similar to the basketball goal.

Abstract: Distance measuring devices and methods are included which may be used to measure and simultaneously display an accurate range of multiple targets such as the flags of a golf practice driving range.

Abstract: A golf training aid with alignment sticks includes an elongate member with a longitudinal axis and a first and second set of holes. The first set of holes is spaced apart farther than the second set. The elongate member also has a target alignment hole positioned in between the first and second set of holes. All the holes are constructed to receive and hold an alignment stick. The golf training aid has least two configurations: a wide hitting box configuration and a narrow box configuration.

Abstract: The present application discloses a portable ball net stand device including two base bodies, a water bag, and a pin; the two base bodies are rotatably connected through the pin, and after separation, they form two separate ball net bases; the base body has an internal space, and there is an upright rod hole and a rotation shaft on the base body; the internal space is used to accommodate the water bag and sports equipment. Because it is relatively light, it is easy to carry when going out for play or venue transfer. By injecting water into the water bag, a weight of the ball net stand device can be increased to enhance a stability of the ball net stand device and prevent problems such as displacement caused by an external force impact. A roller and a handle have been designed to facilitate a user to drag and move.

Abstract: A pickleball identifier and method of personalizing and identifying a pickleball involves inserting a rolled-up polyester/silk circle or oval of fabric into one of the holes in the pickleball, then allowing it to snap open once fully inserted. The circle or oval has an identifying color, written or printed name, or other indicia so that the owner of the pickleball can retain ownership after a game is finished. Because of the circular shape, the identifier has no edges or other protuberances that can fray or be pulled upon to remove the identifier from the pickleball. Should the pickleball crack during play, the identifier can be removed and inserted into another pickleball.

Abstract: Embodiments of the present disclosure enable system(s) and method(s) for creating and deploying an electronic skill-based activity, including implementing a matchup tool to determine a projected performance score for participants in real-world events based at least in part on historical performance data of each participant. The matchup tool creates suggested matchups for inclusion in a skill-based game by selecting, for each suggested matchup, at least two components, formed from one or more participants, expected to produce substantially similar scores in the skill-based game based on the projected performance score of each participant. The matchup tool renders for display to a game operator the suggested matchups to enable the game operator to interactively select suggested matchups for inclusion within the skill-based game.

Abstract: Techniques are described for an encoder or decoder to adaptively change coding based on a specific user's sensitivity to flickering, or flashing, or blockiness, or other visual artifacts. Alternatively, video may be pre-processed based on the user's sensitivity to suppress artifacts prior to encoding and/or post-processed to suppress artifacts after decoding.
