Fall detection system using a combination of accelerometer, audio input and magnetometer
First Claim
1. An apparatus wearable by a user for detecting a user state, comprising:
- an accelerometer;
a magnetometer;
a microphone;
memory; and
at least one processor communicatively connected to the accelerometer, the magnetometer, the microphone, and the memory, and configured to;
identify a suspected user state based on an acceleration measured by the accelerometer and a change of orientation measured by the magnetometer;
categorize the suspected user state as one of an activity of daily life (ADL), a confirmed user state indicating that a fall has occurred, and an inconclusive event;
transmit at least one of the measured acceleration and the change of orientation to a cloud computing system; and
receive a re-confirmation or change of classification from the cloud computing system based on the at least one of the measured acceleration and the change of orientation.

Abstract
A wearable device for detecting a user state is disclosed. The wearable device includes an accelerometer for measuring an acceleration of a user, a magnetometer for measuring magnetic field associated with the user'"'"'s change of orientation, a microphone for receiving audio, a memory for storing the audio, and at least one processor communicatively connected to the accelerometer, the magnetometer, the microphone, and the memory. The processor is identified to declare a measured acceleration as a suspected user state, and to categorize the suspected user state based on the stored audio as one of an activity of daily life (ADL), a confirmed user state, or an inconclusive event.

11. A computer implemented method performed by an apparatus wearable by a user for detecting a fall of a user, the method comprising:
-
measuring an acceleration of the user; measuring a magnetic field associated with the user and calculating an orientation of the user based on the measured magnetic field; identifying, by a processor, the measured acceleration and the calculated change of orientation of the user as a suspected fall; categorizing, by the processor, the suspected fall as one of an activity of daily life (ADL), a confirmed fall, and an inconclusive event; transmitting at least one of the measured acceleration and the calculated change of orientation to a cloud computing system; and receiving a re-confirmation or change of classification from the cloud computing system based on the at least one of the measured acceleration and the calculated change of orientation. - View Dependent Claims (12, 13, 14, 15, 16, 17)
