Abstract
The invention in at least one embodiment includes a method for determining the core body temperature of a person by setting an initial core body temperature with a processor; receiving a heart rate of the person with the processor; calculating a predicted core body temperature with the processor using an extended Kalman filter based on the heart rate and the initial core body temperature; and providing the predicted core body temperature. In another embodiment, a system for performing the method.
Claims20
A method for determining the core body temperature of a person comprising:
- setting an initial core body temperature with a processor;
- receiving a heart rate of the person with the processor;
- calculating a predicted core body temperature with the processor using an extended Kalman filter based on the heart rate and the initial core body temperature;
- and
- providing the predicted core body temperature.
The method according to claim 2, further comprising:
- receiving another heart rate of the person with the processor;
- calculating a new predicted core body temperature using the extended Kalman filter based on the another heart rate and the last predicted core body temperature;
- and
- repeating the receiving another heart rate and calculating a new predicted core body temperature at predetermined intervals.
A system comprising:
- a heart rate data source;
- and
- a processor in communication with said heart rate data source, said processor capable of calculating a core body temperature based on constants and having as the only inputs heart rate information and prior core body temperature data.
A system comprising:
- a heart rate data source;
- and
- a processor in communication with said heart rate data source, said processor having program code embodied therewith, the program code executable by the processor to
- set an initial core body temperature;
- receive a heart rate of the person;
- calculate a predicted core body temperature using an extended Kalman filter having as inputs the heart rate and the initial core body temperature;
- and
- provide the predicted core body temperature.
