1. A body movement monitoring system comprising:

  • a data processing system comprising one or more processor circuits configured to process data generated by a sensor, the data including information representative of at least one signal generated by the sensor in response to movement of an upper part of a body of a person, the data processing system programmed to at least;

    process said data to identify one or more peaks in the at least one signal by comparing one or more parameters with one or more predefined fall thresholds; and

    for at least one identified peak of the one or more peaks;

    process said data to identify a non-fall activity performed by the person during at least one of a time period before said identified peak or a time period after said identified peak; and

    in response to identifying said non-fall activity;

    determine whether said identified peak can be classified as a fall event or a non-fall event based on the one or more predefined fall thresholds;

    in response to determining said identified peak can be classified as a fall event or a non-fall event based on the one or more predefined fall thresholds, classify said identified peak as a fall event or a non-fall event based on the one or more predefined fall thresholds; and

    in response to determining said identified peak cannot be classified as a fall event or a non-fall event based on the one or more predefined fall thresholds;



    set one or more new fall thresholds based on said non-fall activity;



    process a portion of the data corresponding to a time window that encompasses said identified peak to compute one or more parameters; and



    determine whether to classify said identified peak as a fall event by comparing said one or more parameters to said one or more new fall thresholds.
