  • Publication number: 20230057398
    Abstract: The present disclosure relates to at least one method for ascertaining at least one attribute of pressure vessel wall. A method comprises: while a pressure vessel, which comprises a wall having an outer surface and an inner surface, is operating: ascertaining a current wavelength shift of a first fiber Bragg grating (FBG) sensor disposed at a first outer surface location on the pressure vessel; and ascertaining a current thickness of the wall at the first outer surface location by: computing a vector based on a time series of the current wavelength shift, or a derivative of the time series, or a derivative of the current wavelength shift; providing the vector to a predetermined regression model; and using the regression model, ascertaining the current thickness of the wall.

  • Patent number: 10463311
    Abstract: A method for ballistocardiography (BCG) and a BCG system ballistocardiography (BCG) system for heart beat determination are provided. The method includes digitizing a plurality of signals received from a corresponding plurality of sensors, estimating a plurality of smoothed cepstra corresponding to each of the plurality of digitized signals in response to a smoothed cepstrum analysis of a digital signal at a reception time of each of the plurality of digitized signals, and estimating a fused cepstrum for the plurality of digitized signals in response to the plurality of smoothed cepstra. The method further includes determining a heart rate in response to the plurality of smoothed cepstra and the fused cepstrum.

  • Publication number: 20080017017
    Abstract: This invention discloses a method for melody representation and matching able to accommodate pitch and speed variations in the query input The melody is represented by a sequence of data points, which is invariant to the speed or tempo of the melody. For the melody representation, the hummed query is converted to a pitch time series. The pitch time series is then approximated by a sequence of line segments. The line segment sequence in time domain is then mapped into a sequence of points in a value-run domain. The sequence of points is invariant to the time or speed in the original time series. In a data point sequence matching technique, the query data sequence is aligned with the target data sequence in a database. This alignment is done based on important anchor points in the data sequences that can tolerate value variation (pitch and key inaccuracy in the hummed query) and it also helps determine the probable matching candidates from all the subsequences of the target data sequences.

  • Publication number: 20040093354
    Abstract: The invention relates to content-based audio/music retrieval and other content-based multimedia information retrieval. In one aspect the present invention provides a method of representing audio/musical information in a digital representation suitable for use in content-based information indexing and retrieval including the steps of: determining a first representation including a set of peaks and valley corresponding to maximum and minimum values respectively of at least one characteristic of the audio/music, and; determining a second representation including values representing relative differences between peaks and valleys. The invention presents a method and a system for content-based music retrieval. A music score database is constructed to provide a unique representation of real music songs. Score keywords are extracted from the music score as the features of the musing songs.
