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.

Abstract: Apparatus for evaluating a person's foot condition in terms of blood circulation in and anatomical shape of the feet has a transparent planar foot support with a thermographic film provided thereon to visually indicate the degree of blood circulation in the foot. The foot support is mounted on a stand with lamps for illuminating the underside of the foot support. Mirrors are positioned on the stand beneath the foot support to enable unobstructed viewing of the visual indication. By rotating the mirror, a camera may be used to photograph the visual indication of the person's foot condition. The apparatus provides an economic unit for use in readily evaluating a person's foot condition.
