Patent number: 11896398Abstract: An auscultatory sound-or-vibration sensor electronic test signal applied to a sound generator generates an acoustic sound signal, responsive to which an auscultatory sound-or-vibration sensor in proximity to the sound generator generates a corresponding auscultatory sound signal. The auscultatory sound-or-vibration sensor electronic test signal incorporates a plurality of frequency components, each frequency component of which incorporates an integral number of wavelengths and is terminated following a duration of time corresponding to the integral number of wavelengths after that frequency component is applied to the corresponding sound generator. A determination of whether or not the auscultatory sound-or-vibration sensor is functioning properly is made responsive to an analysis of a Fourier Transform of the auscultatory sound signal.Type: GrantFiled: June 28, 2021Date of Patent: February 13, 2024Assignee: AUSCULSCIENCES, INC.Inventors: Jun Zhou, Md Shahidul Islam, Jikang Zeng, Daniel Labonté, Simon Martin, Brady Laska, Sergey A.
