US10888242

1. A method for operating a removable smartphone case, the method comprising: (4) (4)

transmitting radio waves below the skin surface of a person;

receiving radio waves on a two-dimensional array of receive antennas, the received radio waves including a reflected portion of the transmitted radio waves;

generating digital data in response to the received radio waves, wherein the digital data is indicative of a health parameter of the person; and

communicating the digital data generated in response to the received radio waves from the removable smartphone case to a smartphone that is connected to the removable smartphone case.

2. The method of claim 1, wherein the health parameter is a blood glucose level. (0)

3. The method of claim 1, wherein the health parameter is a heart rate. (0)

4. The method of claim 1, wherein the health parameter is a blood pressure. (0)

5. The method of claim 1, wherein radio waves are transmitted from transmit antennas that have at least two different polarization orientations and wherein radio waves are received on antennas of the two-dimensional array of receive antennas that have polarization orientations that correspond to the transmit antennas. (0)

6. A method for operating a health parameter monitoring system, the method comprising: (7) (5)

at a removable smartphone case that is connected to a smartphone, transmitting radio waves below the skin surface of a person;

at the removable smartphone case, receiving radio waves on a two-dimensional array of receive antennas, the received radio waves including a reflected portion of the transmitted radio waves, and generating digital data in response to the received radio waves, wherein the digital data is indicative of a health parameter of the person;

communicating the digital data from the removable smartphone case to the smartphone;

at the smartphone, determining a value that is indicative of a health parameter of the person in response to the digital data received from the removable smartphone case; and

at the smartphone, displaying a visual indicator of the health parameter in response to the determined value.

7. The method of claim 6, wherein the digital data is communicated wirelessly from the removable smartphone case to the smartphone. (0)

8. The method of claim 6, wherein the health parameter is a blood glucose level. (0)

9. The method of claim 6, wherein the health parameter is a heart rate. (0)

10. The method of claim 6, wherein the health parameter is a blood pressure. (0)

11. The method of claim 6, wherein the value that is indicative of a health parameter in the person is determined in response to amplitude data and phase data. (0)

12. The method of claim 6, wherein the value that is indicative of a health parameter in the person is determined in response to amplitude data, phase data, and derived data, wherein the derived data comprises the standard deviation of the amplitude data. (4) (0)

13. The method of claim 12, wherein the derived data comprises a statistic that is derived from the amplitude and/or phase data that is generated over a time window. (2) (0)

15. The method of claim 12, wherein the derived data is a statistic that is derived from amplitude data that is generated over a time window. (0)

17. The method of claim 12, wherein the derived data is a standard deviation of amplitude data that is generated over a time window. (0)

18. The method of claim 12, wherein the derived data is a standard deviation of phase data that is generated over a time window. (0)

19. The method of claim 6, wherein radio waves are transmitted from transmit antennas that have at least two different polarization orientations and wherein radio waves are received on antennas in the two-dimensional array of receive antennas that have polarization orientations that correspond to the transmit antennas. (0)
