1. A method of fall-onset detection, the method comprising the steps of:

  • providing an accelerometer for monitoring acceleration;

    monitoring acceleration at the thigh of a person;

    monitoring acceleration at the waist of the person;

    monitoring orientation of the thigh of the person; and

    detecting the fall-onset ifthe orientation of the thigh exceeds a first threshold value anda correlation between variation in acceleration of the thigh and variation in acceleration of the waist exceeds a second threshold value anda correlation between variation in the orientation of the thigh and a fall-template variation exceeds a third threshold value.
