Information-presentation structure with impact-sensitive color change and restitution matching
First Claim
1. An information-presentation (“
- IP”
) structure comprising an object-impact (“
OI”
) structure having an exposed surface for being impacted by a largely spherical object during an activity, the OI structure comprising;
a principal variable-color (“
VC”
) region which extends to the exposed surface at a principal surface zone and normally appears along it largely as a principal color during the activity, an impact-dependent (“
ID”
) portion of the principal region responding to the object impacting the principal surface zone at an ID object-contact (“
OC”
) area spanning where the object contacts the principal surface zone by temporarily appearing along an ID print area of the principal surface zone largely as changed color materially different from the principal color if the impact meets principal threshold impact criteria, the print area at least partly encompassing, at least mostly outwardly conforming largely to, and being largely concentric with the OC area; and
a secondary region which extends to the exposed surface at a secondary surface zone adjoining the principal surface zone and substantially fixedly appears along the secondary surface zone largely as a secondary color during the activity even when the secondary surface zone is impacted by the object, the object impacting each surface zone with an incident linear vector velocity and an incident angular vector velocity and rebounding from each surface zone with a rebound linear vector velocity and a rebound angular vector velocity, each surface zone having a coefficient of orthogonal velocity restitution and a ratio of tangential velocity restitution for the object impacting that surface zone, the coefficients of orthogonal velocity restitution differing by no more than 15% for the object separately impacting the surface zones at largely identical impact conditions of incident linear and angular vector velocity or/and the ratios of tangential velocity restitution differing by no more than 5% for the object separately impacting the surface zones at largely identical impact conditions of incident linear and angular vector velocity at a reference incident angle of approximately 16°
to the exposed surface where the object impacts the exposed surface.

Abstract
Principal and secondary regions (106 and 108) of an information-presentation structure extend to an exposed surface (102) respectively at principal and secondary surface zones (112 and 114) variously impacted by a spherical object (104) that rebounds from the surface. The principal region normally appears along the principal zone as a principal color. An impact-dependent portion (138) of the principal region responds to the object impacting the principal zone at an object-contact area (116) by temporarily appearing along a print area (118) of the principal zone as changed color materially different from the principal color. The print area closely matches the object-contact area in size, shape, and location. The secondary region fixedly appears along the secondary zone as a secondary color. Restitution matching is provided across the two zones so that the rebound characteristics of the object are largely independent of whether it contacts the principal or secondary zone.
