Abstract
Methods, devices, and systems for contactless cough detection and attribution are presented herein. Audio data may be received using a microphone. A cough may be identified as having occurred based on the received audio data. Radar data may be received indicative of reflected radio waves from a radar sensor. A state analysis process may be performed using the received radar data. The detected cough may be attributed to a particular user based at least in part on the state analysis process performed using the radar data.
Claims20
A contactless cough detection device, comprising:
- a housing;
- a microphone housed by the housing;
- a wireless network interface housed by the housing;
- an electronic display housed by the housing, wherein the electronic display is visible through a screen;
- a radar sensor housed by the housing, wherein the radar sensor emits radio waves through the screen;
- and
- a processing system housed by the housing, comprising one or more processors, that receives data from the microphone and the radar sensor and is in communication with the wireless network interface and electronic display, wherein the processing system is configured to:
- receive audio data from the microphone;
- detect that a cough has occurred based on the received audio data;
- receive radar data indicative of reflected radio waves from the radar sensor;
- perform a state analysis process based on the received radar data for a user within a bed to select a state from a plurality of states;
- attribute the detected cough to the user within the bed based at least in part on the state selected for the user based on the received radar data;
- cause cough data for the user corresponding to the attributed detected cough to be stored;
- and
- output the stored cough data via the electronic display.
A method for performing contactless cough detection, the method comprising:
- receiving, by a contactless cough detection device, an audio data stream from a microphone;
- detecting, by the contactless cough detection device, that a cough has occurred based on the received audio data stream;
- receiving, by the contactless cough detection device, a radar data stream indicative of reflected radio waves from a radar sensor;
- performing, by the contactless cough detection device, a state analysis process based on the received radar data such that a state is selected from a plurality of states for a user within a bed;
- attributing, by the contactless cough detection device, the detected cough to the user within the bed based at least in part on the state selected based on the received radar data;
- storing, by the contactless cough detection device, cough data indicating the attributed detected cough for the user;
- and
- outputting, by the contactless cough detection device, the stored cough data via an electronic display, wherein:
- the electronic display is visible through a screen of the contactless cough detection device;
- and
- the radar sensor emits and senses radar waves through the screen of the contactless cough detection device.
