  • Method and system for quantifying an intention of movement of a user
    Patent number: 8376968
    Abstract: A method for quantifying an intention of movement of a user, the method comprising: extracting a mechanomyogram (MMG) signal in response to surface vibration of a muscle of the user; and averaging the MMG signal by calculating the MMG root mean squared (RMS) amplitude or frequency variance in a predetermined time window; where an increasing RMS amplitude of the MMG signal corresponds to increasing muscle voluntary contraction or a decreasing frequency variance of the MMG signal corresponds to increasing muscle voluntary contraction.
    Type: Grant

    Date of Patent: February 19, 2013
    Assignee: The Hong Kong Polytechnic University

  • METHOD AND SYSTEM FOR QUANTIFYING AN INTENTION OF MOVEMENT OF A USER
    Publication number: 20100292617
    Abstract: A method for quantifying an intention of movement of a user, the method comprising: extracting (61) a mechanomyogram (MMG) signal in response to surface vibration of a muscle of the user; and averaging (62) the MMG signal by calculating the MMG root mean squared (RMS) amplitude (63) or frequency variance (64) in a predetermined time window; where an increasing RMS amplitude of the MMG signal corresponds to increasing muscle voluntary contraction or a decreasing frequency variance of the MMG signal corresponds to increasing muscle voluntary contraction.
