Title:	Methods and apparatus to indicate impact of an object
Abstract:	In one embodiment, an apparatus includes a substrate layer having a first and second sides, and at least one thermochromic compound layer to generate a set of temporary marks. The set of temporary marks is configured to include a first temporary mark at a first impact location associated with a first impact to a surface of a first object by a second object, and subsequent temporary marks at subsequent impact locations associated with subsequent impacts to the surface of the first object. The thermochromic compound layer can be in direct contact with the second object during the first impact, and is configured to enable the first temporary mark to fade throughout a fading period accommodative of the subsequent impacts, and to remain distinguishable throughout the fading period from the subsequent temporary marks. Other examples, embodiments and related methods are described and claimed herein.
