  • Publication number: 20200093426
    Abstract: A method and system of obstructed area determination for sleep apnea syndrome are disclosed. The method comprising obtaining a snoring signal from an individual; obtaining a spectrogram of the snoring signal based on short-time Fourier Transform; obtaining a snoring signal feature based on a harmonic wave of the spectrogram; and obtaining a collapse index by comparing the snoring signal feature against a snoring signal feature-collapse index correlation database. The present invention enables the diagnosis of sleep apnea syndrome and determination the obstructed area for the sleep apnea syndrome with only the snoring signal of an individual during sleep.

  • Patent number: 10500085
    Abstract: The present invention provides a bed set for inhibition of obstructive sleep apnea, which includes: a sound receiving module, is used to receive a respiratory sound signal obtained from a user during a time period; a sound analyzing processor, which is connected with the sound receiving module, is used to obtain a snoring sound characteristic from the spectrum of respiratory sound signal; a database, which has a plurality of snoring image characteristics corresponding to a plurality of basic snoring sound characteristics for different respiratory actions; a control processor, which is connected with the sound analyzing processor and the database, is used to compare the snoring sound characteristic with the basic snoring sound characteristics to select one of the snoring image characteristics in the same waveform, and provides the first angle control order and the second angle control order corresponding to the selecting snoring image characteristic; a first pillow, which is connected to the control processor,
