    • A ball movement path measuring method includes the steps of: preparing an operating unit and a measurement unit, mounting the triaxial accelerometer in the object to be measured for enabling the triaxial accelerometer to define XYZ triaxial space coordinates, obtaining the data of a initial position of the XYZ axes at a first measuring time and the data of a reference position of the XYZ axes at a second measuring time and transmitting the obtained data to the operating unit, and comparing the reference position to the initial position and calculating the XYZ acceleration data, XYZ vector components of force and torsion force relative to each of XYZ axes after receipt of force subject to the contained angle between the coordinates data of the reference position and the coordinate data of the initial position and then using the XYZ acceleration data and the data of the weight and size of the object to calculate the force experienced by the object, initial velocity, flight duration, flight height, flight distance and/or rotation speed.

    • 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.
