Development a Three-dimensional digital based on MEMS sensor, which has the same mass and external dimensions with the normal discus. It can measure the information of acceleration and angular velocity in discus throw. Through calibrating experiments, the digital discus has good linearity and high accuracy, work reliability and better antijamming. This digital discus can be used to collect the signals...
The authors developed a suit of the three-dimensional information collection system of digital discus, which has won the national invention patent. This system includes a digital discus, USB connecting line, position machine software and a personal computer. The digital discus is made up of the higher and lower shell, eyelets, circuit boards, accelerometer and angular rate sensor, etc. This system...
