Self scoring target for darts and similar projectiles

摘要

This invention is an electronic device for detecting, remote indicating, and accumulation of multiple penetrations of a target by conductive shafts such as hand-thrown darts, metal-tipped arrows, or similar missiles. The device utilizes a target comprised of layers of conducting foam pads separated by thin insulating layers. When these foam pads are penetrated by a conducting shaft, they activate an electronic logic system which displays to the player the score that his dart has made on the target.
