Abstract

A system electronically detects and registers contact, especially in contact sport embodiments. An example contacting instrument includes a switch, a tone generator and a conductive mesh. An example detecting instrument includes a conductive mesh and a tone decoder. In a contact sport embodiment, each combatant possesses, for example, as part of the combatant'"'"'s respective uniform, one or more contacting instruments and one or more detecting instruments embedded in prescribed contact zones. The basic goal of a combatant is to strike a contact zone of their opponent with one of their contacting instruments. The detecting instrument will recognize the tone, thereby recognizing a hit.
