Abstract: The present invention provides an automatic tone-following method and system for music accompanying devices, which detects the frequency of the singer's voice instantly and continuously and compares it with the theme tone frequency of the accompanying music to estimate the error between the tones of the singer and the music so as to adjust the tone of the music to match the tone of the singer's voice. The present invention calculates the fundamental frequency of the user's voice every short section of time through a tone estimator, then converts the fundamental frequency of the user's voice into user scale sequence in a scale sequence recorder, then compares the difference between the user scale sequence and the theme scale sequence through a scale matcher. Whether a transposition is needed through a transposition judger is determined so that the scale parameter in the music synthesizer can be adjusted.

Abstract: The present invention relates to a mass analyzing apparatus, comprising a first metal electrode plate, a second metal electrode plate, an RF power supply, a reactant gas and a mass spectrometry. The second metal electrode plate is grounded. There is a gap between the first metal electrode plate and the second metal electrode plate. The RF power supply is electrically connected to the first metal electrode plate. Electric discharge is caused between the first metal electrode plate and the second metal electrode plate, so that the reactant gas becomes dissociation plasma. The dissociation plasma reacts with a gas analyte from a sample and then enters the mass spectrometry for a mass analysis. In addition, since the dissociation plasma is generated under low temperature and atmospheric pressure, the mass analyzing apparatus of the present invention is applicable for biological samples that need to be analyzed at a low temperature.
