Abstract

A multispectral sensor device may include a sensor array comprising a plurality of channels and one or more processors to determine that a time-sensitive measurement is to be performed, wherein the time-sensitive measurement is to be performed using data collected by one or more channels of the plurality of channels; cause the data to be collected by a proper subset of channels, of the plurality of channels, wherein the proper subset of channels includes the one or more channels; and determine the time-sensitive measurement based on the data.

First claim

What is claimed is:

1. A method, comprising:
causing, by a multispectral sensor device and for a first measurement, first data to be collected by a first subset of channels of a plurality of channels,
wherein the first subset of channels is less than all channels of the plurality of channels; and

causing, by the multispectral sensor device and for a second measurement, second data to be collected by a second subset of channels of the plurality of channels,
wherein the first subset of channels is different from the second subset of channels, and
wherein a first time sensitivity of the first measurement is greater than a second time sensitivity of the second measurement.

2. The method of claim 1 , wherein the first data is caused to be collected by the first subset of channels based on the first time sensitivity of the first measurement, and
wherein the second data is caused to be collected by the second subset of channels based on the second time sensitivity of the second measurement.

3. The method of claim 1 , further comprising one or more of:
determining the first measurement based on the first data, or
providing the first data to another device for determination of the first measurement.

4. The method of claim 1 , wherein a first frequency of the first measurement is different from a second frequency of the second measurement.

5. The method of claim 1 , wherein the first measurement is determined with a first latency,
wherein the second measurement is determined with from a second latency, and
wherein the first latency is different from the second latency.

6. The method of claim 1 , further comprising:
determining that the first measurement and the second measurement are to be performed.

7. The method of claim 1 , wherein the first measurement is associated with a first frame rate,
wherein the second measurement is associated with a second frame rate, and
wherein the second frame rate is different from the first frame rate.

8. The method of claim 1 , wherein the first measurement is associated with a first resolution,
wherein the second measurement is associated with a second resolution, and
wherein the first resolution is different from the second resolution.

9. The method of claim 1 , wherein the first subset of channels include a region of interest associated with the first measurement.

10. A device, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
cause, for a first measurement and based on a first time sensitivity of the first measurement, first data to be collected by a first subset of channels of a plurality of channels; and
cause, for a second measurement and based on a second time sensitivity of the second measurement, second data to be collected by a second subset of channels of the plurality of channels,
wherein the second time sensitivity of the second measurement is less stringent than the first time sensitivity of the first measurement.

11. The device of claim 10 , wherein the first subset of channels is less than all channels of the plurality of channels.

12. The device of claim 10 , wherein the one or more processors are further configured to:
determine the first measurement based on the first data, and
determine the second measurement based on second data.

13. The device of claim 10 , wherein multiple iterations of the first measurement and the second measurement are performed.

14. The device of claim 10 , wherein the first measurement is associated with a higher data rate or resolution than the second measurement.

15. A method, comprising:
determining, by using a first subset of channels of a plurality of channels of a multispectral sensor device, a first measurement for a first health parameter; and
determining, by using a second subset of channels of the plurality of channels of the multispectral sensor device, a second measurement for a second health parameter,
wherein the first subset of channels is different from the second subset of channels, and
wherein a first time sensitivity of the first measurement is greater than a second time sensitivity of the second measurement.

16. The method of claim 15 ,
wherein the second measurement is determined after the first measurement is completed.

17. The method of claim 15 , wherein the multispectral sensor device includes a 64-channel multispectral sensor.

18. The method of claim 15 , wherein the multispectral sensor device includes a monolithic multispectral filter that is integrated onto a pixelated sensor.

19. The method of claim 15 , wherein the first health parameter is a cardiopulmonary function parameter of heartbeat, blood pressure, or SpO2 that requires more than 250 samples per second measurements of time-dependent spectral signals in a small number of wavelengths, and
wherein the second health parameter is a spectral health parameter that is not time-dependent.

20. The method of claim 15 , wherein the second subset of channels is all 64 channels of the plurality of channels.
