Abstract

A user monitoring device system has a user monitoring device that includes one or more microphones, a transmitter and sensors to determine air quality, sound level quality, light quality, ambient temperature and humidity near the user. The transmitter serves as a communication system. A radar apparatus or system is configured to detect a user'"'"'s movement information. The radar apparatus or system and the monitoring system configured assist to determine at least one of: user sleep information and sleep behavior information, or user respiration information. A cloud based system is in communication with the monitoring device and the radar apparatus or system.

Claims

1. A system, comprising:

a user monitoring device including a transmitter and one or more sensors, the one or more sensors configured to provide environmental data in response to detecting at least one of an air quality, a sound quality, a light quality, an ambient temperature, or a humidity proximate the user monitoring device;

a radar apparatus configured to detect movement data for an identified user in a region proximate the radar apparatus; and

a monitoring system in communication with the user monitoring device and the radar apparatus, the monitoring system including at least one processor enabled to analyze the movement data in light of the environmental data received from the user monitoring device to determine state information for the user, the state information relating to at least one of user sleep state or user sleep behavior for the identified user.

2. The system of claim 1, further comprising:

a voice activated digital assistant coupled to or included with the user monitoring device; and

a voice recognition system configured to analyze audio data captured using one or more microphones of the user monitoring device.

3. The system of claim 1, wherein the monitoring system is further configured to determine user respiration information using the movement data and the environmental data.

4. The system of claim 1, wherein the one or more sensors comprises at least one of a proximity sensor, a gas sensor, or a barometric pressure sensor.

5. The system of claim 1, wherein the one or more sensors comprises a color meter or sensor.

6. The system of claim 1, wherein the one or more sensors comprises an ultra-violet (UV) sensor.

7. The system of claim 1, wherein the user monitoring device includes a plurality of microphones.

8. The system of claim 1, wherein the radar apparatus includes a radar device coupled to an antenna for non-intrusively monitoring the user.

9. The system of claim 1, wherein the radar apparatus includes at least one of:

a microwave impulse radar (“

MIR”

), a range-controlled radar (“

RCR”

), an impulse radio, or a microwave Doppler device.

10. The system of claim 1, wherein the radar apparatus provides for selection from a plurality of range settings.

11. The system of claim 1, wherein the radar apparatus is configured to monitor the user while ignoring other persons.

12. The system of claim 1, wherein a passive infrared (PR) motion sensor is coupled to the radar apparatus.

13. The system of claim 12, wherein the PIR motion sensor activates or deactivates the radar apparatus based on a presence or an absence of motion of the user.

14. The system of claim 1, wherein the radar apparatus transmits electromagnetic signals and senses corresponding echo signals reflected from the user.

15. The system of claim 1, further comprising:

one or more antennas coupled to the radar apparatus to constrain a radar signal over the person.

16. The system of claim 15, wherein at least one of the one or more antennas employs the at least one antenna to transmit and receive one or more pulse sequences that are sensitive to a monitored parameter.

17. The system of claim 16, wherein the monitored parameter is a body motion of the user.

18. The system of claim 16, wherein the monitored parameter is a physiological motion.

19. The system of claim 18, wherein the physiological motion is a heartbeat of the person.

20. The system of claim 18, wherein the physiological motion is respiration of the person.

21. A user monitoring system, comprising:

at least one processor; and

memory storing instructions that, when executed by the at least one processor, cause the user monitoring system to;

receive environmental data from an environmental monitoring device, the environmental data relating to at least one of an air quality, a sound quality, a light quality, an ambient temperature, or a humidity proximate the environmental monitoring device;

receive movement data captured by a radar apparatus, the movement data corresponding to an identified user in a region proximate the radar apparatus; and

analyze the movement data in light of the environmental data to determine state information for the user, the state information relating to at least one of user sleep state or user sleep behavior for the identified user.

22. The user monitoring system or claim 21, wherein the user sleep state includes information about a current respiration state of the user.
