A baseball is provided with indicia to aid a batter in visualizing direction and loft of a batted ball. By providing a series of projected lofts, a batter can train to hit a ball of varying lofts, ranging from ground balls, to line drives, to pop-ups and any range in between. In addition to projected lofts, one or more projected directional indicators can also be marked on the training ball.

A tennis training device is provided, comprising a support bar which is swivelable between a first and a second stop in its longitudinal direction, wherein at the free end of the support bar a ball is mounted by means of a connecting ember, which is releasably fixed by means of a fixing means. Furthermore, the invention relates to different embodiments of a training unit.

A golf aid system for assisting a user with a golf shot on a golf course includes a user tracking system configured to determine the location of the user on the golf course, a portable electronic device with a display screen, and a processor. The processor, which is operable to communicate with the user tracking system and the portable electronic device, is configured to determine one or more target locations on the golf course, with each of the target locations representing a recommended target for a respective one of the golf clubs. The processor directs the portable electronic device to display an indicator of the respective golf club proximate the corresponding target location via the display screen, such that the user perceives at least a portion of the indicator to be coincident with the corresponding one of the target locations.

A sports ball comprising a cover having an outer substrate surface is provided. The cover may include plurality of panels, wherein each panel has a respective panel surface. The panel surfaces of the respective panels collectively comprise the outer substrate surface of the cover. A surface texture is disposed upon and additively applied to the outer substrate surface. The surface texture is disposed on the respective panel surfaces in customizable, panel-specific, predefined panel arrangements. The surface texture defines surface profile that includes an alternating and repeating series of land areas and raised portions, wherein each raised portion is positioned between a plurality of land areas. The raised portions extend from the outer substrate surface and are formed from a dimensional ink, wherein each of the plurality of raised portions has a terminus that is spaced apart from the outer substrate a height of greater than about 0.05 millimeters (mm).

An instructional training soccer ball with color coded contact zones provided as a tutorial training guide of soccer ball striking skills in the development of novice and young soccer players. The color-coded zones correspond to different types of kicks including passes, strikes, curves, lobs/long balls, and chips, whereby when a player comes into contact with a color-coded zone with the appropriate part of their foot, the soccer ball will produce the corresponding type of kick. The soccer ball may also have one or more legends that is color coded and matches the corresponding contact zones whereby the legends tell the user what part of their foot to kick with, such as the inside foot or laces.

An electronic golf aid system for assisting users with reading greens on golf courses includes a camera that captures images of the user's field of view, and an electronic display device with a display screen that displays captured images. A processor, which communicates with the camera and display device, is programmed to: receive signals from the camera indicative of images of a golf ball and a cup on the green; determine respective locations for the golf ball and cup; determine a perspective view of the topology of the green between the golf ball and cup from the user's point of view; determine, based on the green's topology, a proposed trajectory line from the golf ball's location to the cup's location; and direct the electronic display device to display the proposed trajectory line superimposed on the surface of the green as the green is shown in real-time on the display screen.

A pet toy comprises a ball and at least one feather attached to the ball. When used, the pet toy bounces in various directions and its feathers and pet toy movement attract a pet and trigger the pet's hunting instinct. While chasing and capturing the pet toy, the pet is entertained and exercised. The pet toy disclosed has a high coefficient of restitution and is of particular interest to cats.
