US20190053707

1. A system for monitoring a subject status, the system comprising: (9) (4)

a subject arrangement area for arranging a subject thereon;

a signal transmitter configured to transmit a radar signal toward the subject arranged on the subject arrangement area;

a signal receiver configured to receive the radar signal; and

a signal analysis device configured to detect a temporal variation of the radar signal and determine a subject status based on the temporal variation.

2. The system of claim 1, wherein the subject status includes a subject position. (3) (0)

6. The system of claim 1, wherein the subject status includes a subject incontinence condition. (0)

7. The system of claim 1, wherein the subject status includes a physiological condition of the subject. (0)

8. The system of claim 1, further comprising: (0) (1)

9. The system of claim 1, wherein the radar signal has a band of spectrum between 30 GHz and 300 GHz. (0)

10. The system of claim 1, wherein the radar signal has a wavelength ranging between 10 mm to 1 mm. (0)

11. The system of claim 1, wherein the subject arrangement area includes a patient bed. (0)

12. The system of claim 1, wherein the signal transmitter and the signal receiver are integrally configured as a signal transceiver. (0)

13. The system of claim 1, wherein the signal analysis device is configured to generate a notification of the subject status to a healthcare practitioner. (0)

14. A method for monitoring a subject status, the method comprising: (2) (5)

arranging a subject in a subject arrangement area;

transmitting a radar signal toward the subject;

receiving the radar signal;

monitoring a temporal variation of the radar signal; and

determining a subject status based on the temporal variation.

15. The method of claim 14, wherein the subject status includes a subject position. (2) (0)

18. The method of claim 14, wherein the subject status includes a subject incontinence condition. (1) (0)

20. A system for monitoring a subject status, the system comprising: (0) (4)

a processing device configured to control operation of the system;

a signal transmitter configured to transmit a radar signal having a band of spectrum between 30 GHz and 300 GHz.;

a signal receiver configured to receive the radar signal; and

a computer readable storage medium storing software instructions that, when executed by the processing device, cause the system to: transmit the radar signal toward a subject using the signal transmitter;

receive the radar signal using the signal receiver;

identify at least one body portion of the subject based on the received radar signal;

monitor a temporal variation of the radar signal;

predict an upcoming status of the subject based on the temporal variation; and

determine a wet spot around the subject based on the temporal variation.
