  • Multi-channel ballistocardiography with cepstrum smoothing and quality-based dynamic channel selection
    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.

  • SYSTEM AND METHOD FOR PATIENT MONITORING
    Publication number: 20120184862
    Abstract: A system and method for patient monitoring using an array of pressure sensors, and a computer readable data storage medium having stored thereon computer code means for instructing a computer to execute a method for monitoring a patient using an array of pressure sensors. The method comprising the steps of: determining a value of a selection parameter of each pressure sensor of the array; selecting one more of the pressure sensors based on the respective values of the selection parameter; and measuring a vital sign of the patient based on data obtained from said one or more selected pressure sensors.
