First Claim
Patent Images
1. A fall detector for detecting a potential fall by a user, the fall detector comprising:
- a sensor for measuring the skin conductivity of the user; and
a processor for analyzing the skin conductivity measurements to determine whether the user has had a potential fall, wherein the processor is configured to use a matched filter to match the skin conductivity measurements to a predetermined skin conductivity response corresponding to a stressful event to generate skin conductivity coefficients, the value of each coefficient indicating the match of a respective set of consecutive skin conductivity measurements to the predetermined skin conductivity response; and
to determine whether the user has had a potential fall by analyzing the skin conductivity coefficients.
