  • Respiratory function testing system and respiratory function testing method thereof
    Patent number: 11925454
    Abstract: A respiratory function testing system includes an air transforming device, a sound reception device and an operation device. The air transforming device is configured to collect exhaled and/or inhaled air for a predetermined period and generate a wide frequency range sound signal according to the collected respired air. The wide frequency range sound signal at least contains an ultrasonic signal. The sound reception device is configured to receive and record the wide frequency range sound signal as an audio file. The operation device is in communication with the sound reception device and is configured to receive and compute the audio file to generate a respiratory function parameter. Besides, the recorded wide frequency range sound signal may be converted into a spectrogram for further applications, and the computation of the audio file can be replaced by analyzing the spectrogram. A respiratory function testing method corresponding to the respiratory function testing system is also provided.

  • 3-axis accelerometer with gap-closing capacitive electrodes
    Patent number: 8443670
    Abstract: Disclosed is a novel three-axis capacitive-type accelerometer implemented on SOI wafer. The accelerometer consists of four springs, one proof mass, four pairs of gap-closing sensing electrodes (each pair of gap-closing sensing electrode containing one movable electrode and one stationary electrode), and several metal-vias as the electrical interconnections. The movable electrodes are on the proof mass, whereas the stationary electrodes are fixed to the substrate. The three-axis accelerometer has five merits.
