INFORMATION-PRESENTATION STRUCTURE WITH IMPACT-SENSITIVE COLOR CHANGING INCORPORATED INTO SPORTS-PLAYING STRUCTURE SUCH AS BASKETBALL OR VOLLEYBALL COURT

摘要

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).
