ball game tool for swing speed and swing forces hit a measurable sphere

摘要

(57) [summary] [challenge] swing speed and swing force by using an acousto-optic technology to measure the swing speed and swing force is to provide a ball game tool for hitting a measurable sphere. And A ball instrument main body, a measuring unit, and consists of a display control unit connected with the measuring unit, The measuring unit and a processing circuit and the centrifugal force measurement unit and blow detection unit and centrifugal force measurement unit and blow detection unit is connected, centrifugal force and blow user occurs when the hit the ball by ball game tool body the sound is measured by the centrifugal force measurement unit and hit detection unit, The numerical values ​​and the measured and converted to the swing speed signal and the swing output signal by said processing circuit, wherein the displaying on the display control unit.
