Method for detecting falls and a fall detector

摘要

A method for detecting a fall by a user includes a method of detecting a fall by a user. The method includes processing measurements obtained from one or more sensors to extract a respective value for a plurality of features associated with a fall. A respective log likelihood ratio for each of the values is determined. Whether the user has fallen is determined based on the determined log likelihood ratios.

1. A method of detecting a fall by a user, the method comprising:
with a processor or computer, processing measurements obtained from one or more sensors to extract a respective value for a plurality of features associated with a fall, wherein processing the measurements includes processing measurements obtained from an air pressure sensor to extract values indicating changes in altitude; with a processor or computer, determining a respective log likelihood ratio for each of said extracted values; with a processor or computer, determining whether the user has fallen based on the determined log likelihood ratios; and with a transmitter, in response to determining that the user has fallen, transmitting a signal indicating the user has fallen.
