Abstract
The method for monitoring a person includes a) recording sounds produced by the person during a recording period; b) using a processing unit, implementing a classification algorithm for each sound recorded during the recording period, so as to classify each recorded sound into a set of classes, the set of classes including at least a first class of interest, representative of respiratory abnormalities in the person and/or a change in their breathing pattern; and c) depending on the number of sounds classified in the first class of interest, emitting an alert signal, informing of a potential risk of the person falling.
Claims20
A method for monitoring a person, the method comprising
- a) recording sounds produced by the person during a recording period;
- b) using a processing unit, implementing a classification algorithm for each sound recorded during the recording period, so as to classify each recorded sound among a set of classes, the set of classes comprising at least a first class of interest, representative of a respiratory anomaly or a change in the breathing of the person;
- and
- c) depending on a number of sounds classified in the first class of interest, emitting an alert signal, informing of a potential risk of the person falling.
A monitoring device for monitoring a person, the monitoring device comprising
- a microphone, configured to
- a) record sounds generated by the person during a recording period;
- and
- a processing unit programmed to
- b) from the sounds recorded during the recording period, implement a classification algorithm for each sound recorded during the recording period, so as to classify each recorded sound among a set of classes, the set of classes comprising at least a first class of interest, representative of a respiratory anomaly or a change in the breathing of the person;
- and
- c) depending on a number of sounds classified in the first class of interest, emit an alert signal, informing of a potential risk of the person falling,
- so as to prevent a fall of the person based on the sounds generated by the person during the recording period.
A fall detection device, comprising:
- a sensor configured to detect movement or sound of a person;
- and
- a detection unit programmed to detect a fall of the person based on a characteristic of a signal resulting from the sensor, the detection unit being configured to indicate a fall when the characteristic exceeds a detection threshold;
- wherein the fall detection device is connected to a monitoring device for monitoring a person, the monitoring device comprising
- a microphone, configured to
- a) record sounds generated by the person during a recording period;
- and
- a processing unit programmed to
- b) from the sounds recorded during the recording period, implement a classification algorithm for each sound recorded during the recording period, so as to classify each recorded sound among a set of classes, the set of classes comprising at least a first class of interest, representative of a respiratory anomaly or a change in the breathing of the person;
- and
- c) depending on a number of sounds classified in the first class of interest, emit an alert signal, informing of a potential risk of the person falling,
- so as to prevent a fall of the person based on the sounds generated by the person during the recording period,
- wherein the detection unit of the fall detection device is programmed so that the detection threshold is adjusted according to an alert signal emitted by the processing unit of the monitoring device.
