Table tennis ball storage devices provide a convenient place to store and retrieve table tennis balls during a game of table tennis. The ball storage device has an inner storage volume for receiving and retaining table tennis balls that is accessible from two openings, one designed to place table tennis balls into the storage volume and a second designed for removing table tennis balls. The first opening may be conveniently located on a playing end of a table tennis table and the second opening may be located on either the left or right side of the table tennis table. The first opening has a different shape than the second opening.

A table is disclosed. The table comprises a table base and tabletop. The table base comprises a top surface with a replaceable adhesive layer attached. The tabletop comprises a first usable side and a second usable side, the first usable side and the second usable side being alternately attached to the replaceable adhesive layer once the adhesive is cut, removed, and replaced. The top surface further comprises a rounded edge that acts to guide the entry of an adhesive cutting wire. The replaceable adhesive layer comprises embedded wire guides that define a cutting zone substantially the width of the cutting wire through the adhesive. The embedded wire guides restrict the cutting wire to the cutting zone while the adhesive is being cut, thereby allowing the first usable side and the second usable side to be alternately attached to the adhesive layer.

A multifunctional desk includes a top plate, a leg portion that supports the top plate in air, a rotating shaft provided below and parallel to the top plate, a rotating plate provided below the top plate, a first fixture, a second fixture, and a slide plate provided below the top plate and above the rotating plate. The first fixture fixes the rotating plate to the top plate or releases the rotating plate from being fixed to the top plate in a state of protruding in front of the top plat. The second fixture fixes the rotating plate to the top plate or releases the rotating plate from being fixed to the top plate in a state of being retreated below the top plate. The slide plate protrudes in front of the top plate or is retreated below the top plate by sliding in parallel to the top plate.

An RFID system includes multiple antennas and uses amplitude and phase information of the RFID signals received by each antenna to determine the position of RFID tags in the vicinity. More than one antenna can receive the RFID signals during a single read cycle, enabling the RFID system to operate more quickly than a system that energizes antennas separately.

The present disclosure relates to a support system for a gaming table including a first support bar of a gaming-table support, a second support bar of a gaming-table support, a third support bar of a gaming-table support, and a gaming-table support locking apparatus. The third support bar has an arcuate shape and is in a pivotable connection with the second support bar. The gaming-table support locking apparatus includes a first locking bar and a second locking bar. The second locking bar is configured to be in one of two states of being: a first state that allows the third support bar to rotate with respect to the second support bar; and a second state that prevents the third support bar to rotate with respect to the second support bar.

A board-carrying support device includes a supporting frame and a bearing board having a bearing surface. The bearing board is pivotally mounted to the supporting frame to allow adjusting an inclination angle of the bearing surface based on the pivoting of the bearing board with respect to the supporting frame, so that the inclination angle of the bearing surface can adapt to the visual angle of the jigsaw puzzle player, which helps the jigsaw puzzle player to comprehensively focus on the puzzle pieces located at various parts of the bearing surface and to conveniently touch and pick up the puzzle pieces located at various parts of the bearing surface in the game process, so that the game experience of the puzzle game is improved, and the attraction of the puzzle game to the player is improved.
