A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112) and normally appears along it as a principal color. An impact-dependent portion (138) of the variable-color region responds to an object (104) impacting the zone at an object-contact area (116) by temporarily appearing along a print area (118) of the zone as generic changed color materially different from the principal color. The print area closely matches the object-contact area in size, shape, and location. The threshold impact criteria consist of multiple sets of different threshold impact criteria respectively associated with multiple specific changed colors materially different from the principal color. If the impact meets the threshold impact criteria, the generic changed color is the specific changed color for the criteria set met by the impact.

A snowball launching and batting apparatus comprising a barrel member, a handle member, and a knob feature, the handle member further comprising a primary cradle structure configured to accept, form, and store snow or snowballs. The apparatus further comprises a secondary cradle structure capable of coupling the primary cradle structure and configured to accept, form, and store snow or snowballs. The knob feature may further comprise a depression configured to form snowballs. The apparatus is further configured to have an extended and retracted state. A user inserts snow into the barrel and cradle structure to form a snowball and inserts it into the apparatus while in an extended state. Launching the snowballs from the apparatus may comprise swinging the apparatus or applying a force to the handle member to quickly move it from an extended state to a retracted state.

A sporting robotic device apparatus, system, method and/or computer program product may provide an electronically programmably controlled sporting device. Certain embodiments include a plurality of sporting devices coupled to a robot or a plurality of the at least one robots, where the plurality of robots each include a sporting device coupled to the plurality of robots, and where each robot includes a plurality of joint axes, motors, and structural members. The sporting robotic device can further include an electronic user interface coupled to the robots and an electronic computer processor, memory, input and output devices, and can include further features as claimed including at least one of the user interface with devices coupled thereto, the computer processor configured to save or retrieve a sporting routine from memory, to randomize a challenge, or configured to combine sporting routines, or shuffle sporting routines, previously saved.

A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112) and normally appears along it as a principal color. An impact-dependent portion (138) of the variable-color region responds to an object (104) impacting the zone at an object-contact area (116) by temporarily appearing along a print area (118) of the zone as generic changed color materially different from the principal color. The print area closely matches the object-contact area in size, shape, and location. Sound-generating apparatus (602 or 702) selectively generates a specified audible sound in response to the object impacting the object-contact area so as to meet the threshold impact criteria. The specified sound is separate from any audible sound originating at the object-contact area due physically to the impact.

A method and apparatus for forming a sporting racquet handle wherein the racquet has a rectangular cross-section handle base. The apparatus comprises a first sleeve portion having a first sleeve interior adapted to engage upon the handle base and a first sleeve exterior shaped to form a first handgrip portion, a second sleeve portion having a second sleeve interior adapted to engage upon the handle base and a second sleeve exterior shaped to form a second handgrip portion, and connectors for securing the first sleeve portion to the second sleeve portion around the handle base so as to mate the first handgrip portion with the second handgrip portion to form a continuous handgrip around the handle base. The method comprises securing a first sleeve portion around the handle base and securing a second sleeve portion around the handle base to as to form a continuous handgrip around the handle base.

The disclosure discloses a thermal expansion compound for handles, a preparation method, and applications thereof. The thermal expansion compound for handles is prepared by 20-80 wt of thermosetting resin, 5-50 wt of foaming agent, 5-50 wt of stuffing, and 0-60 wt of diluent. The thermal expansion compound for handles applies to the preparation of various sports instruments such as tennis rackets, badminton rackets, squash rackets, PK rackets, beach rackets, flexible rackets, ball bats and clubs. Handles prepared from the thermal expansion compound have an elegant appearance and a good hand feel, avoid secondary expansion during 100-160 C. post-heating treatment, and have a hardness of SHORE D 60-95.

The invention relates to a basket for the game of Basque pelota comprising a rigid structure that makes up the mouth of the basket, which defines a conventionally formed rim similar to that of a conventional basket, to the ends of which a longitudinally curved paddle is fastened with a similar configuration to that of the central rib of a conventional basket, which transversely has a concave section with greater depth at the central area or box than on the end areas close to the tip and to the proximal end of the piece, which is fastened by a series of transverse tensioners, which include a concave piece on the inside thereof that occupies the middle area of the basket in the area of impact, hulling and the exit of the ball towards the tip, which closes the gap existing between the paddle and the rigid structure by both sides.

A variable-color region (106) of a sports-playing structure of an information-presentation structure extends to an exposed surface (102) at a surface zone (112), normally appears along it as a principal color, and includes impact-sensitive and color-change components (182 and 184). A boundary line (1306/1308 or 1386/1388) extends along an in-bounds area (1302 or 1382) of the surface. A segment (192) of the impact-sensitive component responds to an object (104) impacting the zone at an object-contact area (116) by providing an impact effect if the impact meets threshold impact criteria. A segment (194) of the color-change component responds to the impact effect by causing an impact-dependent portion (138) of the region to temporarily appear along a print area (118) of the zone as changed color materially different from the principal color. The zone typically adjoins the boundary line or an internal line (1334 or 1396).

A weight apparatus suitable for attaching to athletic equipment includes a flexible main body of a weight material, wherein the flexible main body is formed into a flattened strip that has a length along its y direction that is significantly greater than its width along its x direction, wherein the flexible main body is configured to be malleable to conform in a curved manner to wrap along a head of a sporting racket and around a handle of a hockey stick.

A system for determining a position of one or more pieces of athletic equipment on an athletic playing surface is provided. The system includes one or more pieces of athletic equipment each including therein an RFID chip, the RFID chip comprising an electronic circuit configured to produce and transmit an RF signal. The system also includes an array of sensors positioned on or in proximity to the athletic playing surface and configured to receive RF signals from the RFID chip of each of the one or more pieces of athletic equipment. The system also includes a processing system operably connected to the array of sensors to receive data from the array of sensors, the processing system programmed to process the data from the array of sensors to determine a position of each of the one or more pieces of athletic equipment on the athletic playing surface.
