    摘要: A method and device for automatically detecting heart valve damage for four heart valves are proposed. The automatic determination method makes use of three or more heart tone microphones to simultaneously record heart tones of a patient's heart, and then separates the heart tones into four heart tone signals of the aortic valve, the pulmonary valve, the tricuspid valve and the mitral valve of the heart based on the timing characteristics and related techniques. Next, these four heart tone signals are digitally processed into sampling signals. Subsequently, the convolution method is used to process the sampling signals for producing system transfer functions. Finally, the system transfer functions and the reference database are compared to verify and determine damage for the four heart valves. The automatic determination method can judge heart valve damage to enhance the quality and convenience of medical treatment.

    摘要: A dynamic pressure sensing structure used in a condenser microphone includes an upper electrode plate, a lower electrode plate, a spacer and a substrate, wherein the upper and lower electrode plates are separated by the spacer and form a resonance cavity with the substrate. The upper electrode plate comprises a flat vibration area and a surrounding flexible area connected thereto. The lower electrode plate comprises a sensible electrode and an actuation electrode surrounding the sensible electrode. The plate is in connection with the flexible area so that a capacitor is formed between the sense area and the flat vibration area. The actuation electrode provides a polarization voltage to generate an electrostatic force, thereby attract the flexible vibration area to curve downwards so that the flat vibration area moves in a flat state and a distance between the flat vibration area and the sensible electrode is varied correspondingly.

    摘要: A stethoscope capable of eliminating unwanted sounds and method thereof, the stethoscope and method thereof mainly use a stethoscope head containing a sensor and a signal processing circuit. By way of detecting and judging whether the stethoscope head arrives on correct stethoscopic position by the sensor, unwanted sounds generating by frictions, translations, or collisions during the stethoscopic process can be effectively eliminated such that the stethoscopic quality can be improved. Thus, a doctor can use less time and spirit to make a correct diagnosis for a patient with least unwanted interference sounds.
