Technical Examples
  1. A dartboard has board member, and the board member has a plurality of target blocks to be stuck by darts. The back side of the board member has an induction layer and a magnetic member. The magnetic member provides a fixed magnetic field, and the induction layer has a substrate and a circuit on the substrate. A dart with a steel iron or iron alloy point sticks into the board member, and disturbs the distribution of the magnetic field provided by the magnetic member, causing electromagnetic induction and inducing a current in the circuit of the induction layer to provide an automatic score.
