To fully evaluate the quality of movement the athlete performed, sports biomechanics information acquisition and analysis at barycenter is conducted based on Miniature Inertial Measurement Unit. The methods to acquire accurate speed, key point identification and index of redundant movement of the subject are proposed. Key point detection is realized by cascaded logical analysis. Velocity estimation is derived by approximate equation. Gesture Energy index is proposed which provides quantity clue for distinguishing of sports quality based on angular velocity record from Miniature Inertial Measurement Unit corresponding to key point. Experiments of measurements on athletes are done to prove the validation of the methods put forward. The velocity results of approximate equation are comparable to the results of video analysis. Phase identification procedure and Gesture Energy index are also proven to be practicable. The methods could offer some aided information to coaches in daily training.

We derive analytic solution of the particular case of the optimal quantum measurement between pure state and mixed state of the multi-level system. In order to figure out the physical essence rather than the facial complex mathematical expression, we restrict the system to be3-level and the mixed state to be a diagonal matrix to get a obvious result. Generally the optimal solution is determined by the 9 free elements of the transformation unitary matrix. To our surprise, the results actually are so simple that we just have to search 3-dimensional Hilbert space for the optimal solutions. However, the optimal solutions depend on the relative scale among the diagonal elements. Some guessing analytical solution of the optimal target function is given, but the general cases of transformation between mixed state and pure state without imposing these restrictions is still unavailable.
