The at least two receivers receive the UWB data packets and transmit to the processor with time stamps. The processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

A method for retrieving a ball on and about a sports court and for controllably releasing the ball includes a retriever having a vertical ball ejector, and upon ball collection, returning the ball to a desired location in the air or along the sports court surface. The sports court may be a tennis court or a pickleball court, with the method for retrieving and returning a ball being conducted with tennis balls or pickleballs on the respective court type.

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.

There is described a rebound wall to be positioned with respect to a playing surface having an activity area and configured for varying a rebound of a ball directed thereon, the rebound wall comprising: a wall having a rebound surface and adapted to be positioned vertically relative to the playing surface so that the rebound surface substantially faces the activity area; the rebound surface comprising a plurality of impact zones each for returning the ball according to a respective type of shot, each impact zone comprising at least one rebound region each for rebounding the ball along a respective rebound direction towards the activity area upon the ball impacting thereon, each rebound region being shaped as a function of the respective rebound direction the type of shot of the respective impact zone in which the rebound region is contained.

A wrist strengthening device includes a first handle, a second handle, and a tightening component in the form of a clamp configured to tighten around at least a portion of the first handle and at least a portion of the second handle. A sleeve is positioned radially between 1) the tightening component and 2) the at least a portion of the first handle and the at least a portion of the second handle. An interior member in the form of a rod extends from at or near an axial end of the first handle to at or near an axial end of the second handle. The device further includes a first end cap at the axial end of the first handle and a second cap at the axial end of the second handle. The wrist strengthening device is devoid of any spring component.

The invention relates to a sports ball comprising a rubber core and optionally a felt, the rubber core defining an internal volume and an outer surface, the felt being provided on the outer surface of the rubber core, and the rubber core comprising: natural and/or synthetic rubber; and a biodegradability-enabling additive comprising at least one organic compound in a carrier material, wherein the organic compound is a nutrient substrate for an active landfill or marine environment strain of bacteria. The invention further relates to a method for manufacturing a tennis ball including: a) mixing natural rubber and butadiene rubber with further ingredients and the biodegradability-enabling additive; b) extruding a portion of the mixture; c) utilizing the extruded portion for forming a shellpart; d) assembling a core by attaching at least two shellparts to each other; e) inflating the core; and f) providing a felt on the surface of the core.

An aqueous adhesive for rubber includes rubber latex and an ammonium-salt-based vulcanization acceleration aid. An amount of the ammonium-salt-based vulcanization acceleration aid contained in the aqueous adhesive is preferably not less than 0.01% by weight and not greater than 5.0% by weight in terms of solid content. An aqueous adhesive for a ball includes rubber latex as a main component. A content of an inorganic filler in the aqueous adhesive is not greater than 0.1% by weight in terms of solid content. A ball 2 includes a hollow core 4 obtained by crosslinking a rubber composition that contains a vulcanizing agent. The core 4 is formed of two hemispherical half cores. The two half cores are adhered to each other by using the aqueous adhesive for a ball.

The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the processor with time stamps. The processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

A handle for sport equipment comprises a tubular body (7) which extends along a longitudinal axis (L) and has an outer peripheral surface (8) adapted to be grasped by a user and shaped with a plurality of longitudinal faces (9) placed side by side in correspondence of edges (10) adapted to facilitate the positioning of the finger joints of the gripping hand by the user. The edges (10) are arranged along at least one pair of helical or spiral paths that develop around said longitudinal axis (L) with mutually opposite sign to subdivide each of said longitudinal faces (9) into a plurality of areas or flat surfaces (11) sized to accommodate a corresponding phalanx of the gripping hand of the user, each of said areas or flat surfaces (11) being perimetrically delimited by at least one pair of edges (10, 10) of each of the helical or spiral paths.

Disclosed herein is a grip comprising an internal bore with an opening having an internal tapered edge. The grip can engage with a tool or a piece of sports equipment. Further disclosed herein is a method of installing a grip onto a tool or piece of sports equipment, including providing a grip having a tubular body; grinding an open first end of the body, wherein the open first end comprises a greatest diameter closest to the exterior of the bore and tapers internally at an angle towards the interior of the bore; providing a shaft or handle; applying an adhesive to a top portion of the handle; sliding the handle into the grip bore until the shaft contacts the a capped second end of the grip; and coupling a surface of the bore to the handle by allowing the adhesive to dry.
