SYSTEM METHOD AND DEVICE FOR DETERMINING THE RISK OF DEHYDRATION
First Claim
1. A method of determining a probability of dehydration of a person, comprising:
- receiving data of a heart rate of the person over a time period from a first sensor;
receiving data of a posture of the person over the time period from a second sensor;
storing in a memory data of the heart rate of the person over the time period;
storing in the memory data of the posture of the person over the time period;
determining, via a processor, that the posture of the person during the time period satisfies a similarity threshold with a posture envelope, wherein the posture envelope comprises a first posture and a second posture;
determining, via the processor, a first heart rate for the person while in the first posture;
determining, via the processor, a second heart rate for the person while in the second posture;
determining, via the processor, a change in heart rate as a difference between the second heart rate and the first heart rate;
determining, via the processor, a first probability of dehydration based, at least in part, on the change in heart rate; and
outputting the first probability of dehydration.

Abstract
A system, device and method of determining a probability of dehydration of a person is provided. In one embodiment, the method comprises receiving data of a heart rate of the person; receiving data of a posture of the person; determining that a first posture of the person satisfies first posture criteria for a first predetermined time period; determining that the posture of the person satisfies a similarity threshold with a posture envelope; determining a first heart rate for the person while in a first posture; determining a second heart rate for the person while in the second posture; determining a change in heart rate as a difference between the second heart rate and the first heart rate; determining a first probability of dehydration based at least in part on the change in heart rate; and outputting the first probability of dehydration.

18. A system for determining a probability of dehydration of a person, comprising:
-
a first sensor configured to receive data of a heart rate of the person over a time period; a second sensor configured to receive data of a posture of the person over the time period; a memory configured to store data of the heart rate of the person over the time period, and further configured to store the data of the posture of the person over the time period; and a processor configured to; determine that the posture of the person during the time period satisfies a similarity threshold with a posture envelope, wherein the posture envelope comprises a first posture and a second posture; determine a first heart rate for the person while in the first posture; determine a second heart rate for the person while in the second posture; determine a change in heart rate as a difference between the second heart rate and the first heart rate; and output the first probability of dehydration. - View Dependent Claims (19, 20)
