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.

Abstract
A method and system for fall-onset detection is provided. The method includes the steps of 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 if the orientation of the thigh exceeds a first threshold value and a correlation between variation in acceleration of the thigh and variation in acceleration of the waist exceeds a second threshold value and a correlation between variation in the orientation of the thigh and a fall-template variation exceeds a third threshold value.

15. A system for fall-onset detection, the system comprising:
-
a first accelerometer for monitoring acceleration at the thigh of a person; a second accelerometer for monitoring acceleration at the waist of the person; a gyroscope for monitoring orientation of the thigh of the person; and a processor coupled to the first and second accelerometers and to the gyroscope for detecting the fall-onset, the processor being operable to detect the fall-onset based if the orientation of the thigh exceeds a first threshold value and a correlation between variation in acceleration of the thigh and variation in acceleration of the waist exceeds a second threshold value and a correlation between variation in the orientation of the thigh and a fall-template variation exceeds a third threshold value.
