Abstract: A sports ball may include an interior bladder and a cover disposed about the bladder. The cover comprises a plurality of adjoining panels, wherein each panel defines a plurality of panel edges that each extend in a predetermined edge direction along an edge length of less than 7.5 centimeters. The cover may further define a plurality of interior channels. Each interior channel extends in a predetermined channel direction along a channel length of less than 7.5 centimeters. The panel edges and the interior channels are staggered, such that each edge direction is obliquely angled with respect to each of the other edge directions, and each interior channel direction is obliquely angled with respect to each of the other interior channel directions and each of the edge directions of the respective panel. Such an arrangement limits directional feature length and promotes a balanced topography upon the exterior surface of the ball.

Abstract: According to one embodiment, an assembly ball includes a plurality of strips having a circumferential length.

Abstract: An inflatable sports ball is provided. The sports ball includes an interior bladder and a cover disposed about the interior bladder. The cover may include an outer substrate and an intermediate structure. The cover may further include an outer substrate surface, defined by the outer substrate, and a feature surface radially spaced apart from the outer substrate surface. Together the outer substrate surface and the feature surface cooperate to define an exterior surface of the cover. A mechanoluminescent material may be embedded in a portion of the cover. The mechanoluminescent material may be disposed at only one of the outer substrate surface and the feature surface, such that it is positioned to form a predetermined design on the cover. The mechanoluminescent material emits visible light in response to an externally-applied stress, such that the predetermined design illuminates when an external stress or mechanical stimulus is exerted upon the cover.

Abstract: The present invention pertains to a golf tee comprising a stem portion and a top portion connected to the stem portion, the top portion includes an upper surface that opposes the stem and having a convex shape, free of an adhesive layer or material that anchors the ball on the upper surface against uneven ground. The golf tee minimizes friction and other impeding forces between the tee and the ball by reducing an area of contact between the tee and the ball, while preventing the player from installing the golf tee other than vertically into the ground, or horizontal to the Earth's surface, thereby preventing the golf player from having to alter his or her posture and stroke according to the mounting of the ball.
