ABSTRACT:
A target for grade metal tipped darts has a conductive rigid web made up of concentric rings intersecting spokes emanating from the second to the innermost ring. The spokes define twenty sectors, while the rings define 4 segments within each sector. There are also two segments in the innermost and second to innermost rings. Conductive blocks, made up of an aluminum or zinc cup having contacts protruding from its bottom and containing a rubberized cork insert, fill in the segments of the web. Beneath each cup is a silicon foam cushion cut away between the contacts and a pad on a printed circuit board. The pads are each connected to circuitry that senses when a dart hits an insert causing the corresponding cup to slide within the web and contact a pad. The circuitry, by way of a piezoelectric sensors, also determines if a dart has impacted on or near the target and checks to see if the target has polled a segment that indicates a hit on the target, failing which the target indicates that the dart missed the target. The circuitry also senses the rotational orientation of the target and sets the basic scores of the segments accordingly, allowing the target to be periodically rotated to reposition segments in sectors of heavy use to sectors of lighter use.
