Abstract
A target, such as a dart board, has a target face defining a
plurality of beds into which the darts are to be embedded. The
target comprises two superimposed layers of conductive elements
located under the face of the target. The conductive elements of
each layer are insulated from each other and the arrangement is such
that a unique pair of elements, one from each layer, lies under each
bed. Separate electrical identifying signals are applied to the
conductive elements of one of the layers, and means are provided for
detecting signals present on the conductive elements of the second
layer. When a projectile is embedded in the target the shaft of the
dart interconnects the two layers lying under that bed, and thus
signals on the first layer are connected to the second layer, and
are detected, enabling the location of the dart to be determined.
Thus the score during a game of darts can be kept automatically.
