Abstract

Systems and methods are described for controlling acquisition of sensor information, including: one or more condition sensors, one or more physiological sensors, and a computing device including a processor programmed to query the condition sensors to initiate measurement of one or more conditions of an individual relative to the one or more physiological sensors; receive a set of condition sensor values from the condition sensors; assign a predictive value to the set of condition sensors values; query at least one of the one or more physiological sensors to measure one or more physiological parameters of the individual if the assigned predictive value of the set of condition sensor values meets or exceeds a minimum predictive value threshold; and re-query at least one of the one or more condition sensors if the assigned predictive value of the set of condition sensors fails to meet or exceed the minimum predictive value threshold.

First claim

What is claimed is:

1. A system, comprising:
a network of sensors including
one or more physiological sensors configured to sense a physiological parameter of an individual; and
one or more condition sensors configured to sense a position of the individual relative to the one or more physiological sensors; and

a computing device operably connected to the one or more condition sensors and the one or more physiological sensors, the computing device including a processor programmed to
query at least one of the one or more condition sensors to initiate measurement of the position of the individual relative to the one or more physiological sensors;
receive a set of condition sensor values from the at least one of the one or more condition sensors, the set of condition sensor values representative of the position of the individual relative to the one or more physiological sensors;
query at least one of the one or more physiological sensors to measure the physiological parameter of the individual if the set of condition sensor values meets or exceeds a threshold value; and
re-query at least one of the one or more condition sensors if the set of condition sensor values fails to meet or exceed the threshold value.

2. The system of claim 1 , wherein at least one of the one or more condition sensors includes at least one transmission unit including an antenna configured for wireless communication with the computing device.

3. The system of claim 1 , wherein the one or more physiological sensors include one or more non-contact physiological sensors.

4. The system of claim 1 , wherein the one or more physiological sensors include one or more micro impulse radar-based sensors.

5. The system of claim 1 , wherein at least one of the one or more physiological sensors is configured to detect one or more physiological parameters of the individual diagnostic for heart failure.

6. The system of claim 1 , wherein at least one of the one or more physiological sensors includes at least one transmission unit including an antenna configured for wireless communication with the computing device.

7. The system of claim 1 , wherein the computing device is programmed to query the at least one of the one or more condition sensors to initiate measurement of one or more position parameters including proximity, visibility, line-of-sight, motion, or acceleration of the individual relative to the one or more physiological sensors.

8. The system of claim 1 , wherein the computing device is programmed to query the at least one of the one or more condition sensors in response to a triggering event.

9. The system of claim 1 , wherein the computing device is programmed to query the at least one of the one or more condition sensors to initiate measurement of the position of the individual relative to the one or more physiological sensors in response to a flag indicating a need to measure the physiological parameter of the individual based on one or more need-measurement criteria.

10. The system of claim 1 , wherein the threshold value for a set of condition sensor values is represented as a position of the individual relative to the one or more physiological sensors sufficient to acquire a set of physiological sensor values from the one or more physiological sensors.

11. The system of claim 1 , wherein the computing device is programmed to query the at least one of the one or more physiological sensors to measure the physiological parameter of the individual if the set of condition sensor values meets or exceeds the threshold value and at least one flag indicating a need to measure the physiological parameter of the individual is active based on one or more need-measurement criteria.

12. The system of claim 11 , wherein the one or more need-measurement criteria include a number of queries needed over time for a reliable diagnosis.

13. The system of claim 1 , wherein the computing device including the processor is further programmed to
receive a set of physiological sensor values from at least one of the one or more physiological sensors, the set of physiological sensor values representative of the measured physiological parameter of the individual;
assign a quality value to the set of physiological sensor values received from the at least one of the one or more physiological sensors;
