Abstract
Various devices, systems and methods for performing contactless monitoring of the sleep of multiple users over a same time period are presented herein. A determination may be made that two users are present within the region. In response to determining that two users are present, a first portion of the data may be mapped to a first user and a second portion of the data may be mapped to a second user. Separate sleep analyses are performed for the first user and the second user.
Claims20
A contactless sleep analysis device for monitoring multiple users, comprising:
- a housing;
- a radar sensor, housed by the housing, that emits radar and generates radar data based on radar reflections, wherein the contactless sleep analysis device is configured to be pointed toward a bed where one or more users sleep;
- a processing system, comprising one or more processors, housed by the housing, in communication with the radar sensor, wherein the processing system is configured to:
- receive radar data from the radar sensor;
- process the radar data from the radar sensor, comprising applying a movement filter to remove radar data indicative of static objects, wherein the processed radar data comprises a first dimension representative of distance, a second dimension representative of magnitude;
- determine that two users are present;
- after determining that the two users are present:
- assign a first portion of the processed radar data to a first user;
- and
- assign a second portion of the processed radar data to a second user;
- perform a first sleep analysis on the first portion of the processed radar data for the first user;
- perform a second sleep analysis on the second portion of the processed radar data for the second user, the second sleep analysis being independent of the first sleep analysis;
- and
- output sleep information for the first user based on the first sleep analysis.
A method for contactless sleep monitoring of multiple users, the method comprising:
- receiving, from a radar sensor, a radar data stream based on radio waves emitted into a region;
- process the radar data stream from the radar sensor by a processing system, comprising applying a movement filter to remove radar data indicative of static objects, wherein the processed radar data comprises a first dimension representative of distance, a second dimension representative of magnitude;
- determine that two users are present;
- after determining that the two users are present:
- assign a first portion of the processed radar data to a first user;
- and
- assign a second portion of the processed radar data to a second user;
- perform a first sleep analysis on the first portion of the processed radar data for the first user;
- perform a second sleep analysis on the second portion of the processed radar data for the second user, the second sleep analysis being independent of the first sleep analysis;
- and
- output sleep information for the first user based on the first sleep analysis.
