Integrating Wave Sensing and Magnetic Induction Dartboard System

Abstract

An integrating wave sensing and magnetic induction dartboard system comprises: a magnetic induction dartboard, a wave sensing device, and an electronic scoring circuit. The waving sensing device is fixed on the magnetic induction dartboard and is connected to the electronic scoring circuit. When the electronic scoring circuit receives the magnetic signal and the wave signal simultaneously, a score will be created. The abovementioned system still can produce accurate scoring data in the presence of electromagnetic interference. It can determine if the target is missed or not based on the shock or sound caused by dart’ landing.
