Heart rate monitor device
First Claim
1. Heart rate monitor device for monitoring a heart rate of a user, comprising:
- at least one primary sensor for measuring a heart rate of user, wherein the at least one primary sensor has a first power consumption,at least one secondary sensor for measuring at least one physiological factor influencing the heart rate of a user, wherein the at least one secondary sensor has a second power consumption which is lower than the first power consumption,a power management unit for managing an operation of the at least one primary sensor based on information received from the at least one secondary sensor,a model unit for estimating the heart rate of a user based on a model stored in the model unit and the information received from the at least one secondary sensor, wherein the model unit is coupled to the power management unit via a feedback loop such that the power management unit is adapted to decrease a sampling frequency and/or measurement intensity of the primary sensor if the estimated heart rate and the measured heart rate correspond to each other.

Abstract
A heart rate monitor system (100) for monitoring a heart rate of a user is provided. The heart rate monitor system (100) comprises at least one primary heart rate sensor (110) for measuring or determining a heart rate of a user. The at least one primary heart rate sensor (110) has a first power consumption. The heart rate monitor system (100) also comprises at least one secondary sensor (120) for measuring at least one physiological factor influencing the heart rate of a user. The at least one secondary sensor (120) has a second power consumption which is lower than the first power consumption of the at least one primary heart rate sensor (110). The heart rate monitor system (100) further comprises a power management unit (160) for managing an operation and/or power consumption of the at least one primary heart rate sensor (110) based on information (126) from the at least one secondary sensor (120). The heart rate monitor system comprises a model unit for estimating a heart rate of a user based on a model stored in the model unit and information received from the at least one secondary sensor. The model unit is coupled to the power management unit via a feedback loop such that the power management unit is adapted to compare the estimated heart rate with the measured heart rate and to control the operation of the primary sensor in dependence on the comparison.

6. Method of monitoring a heart rate of a user comprising the steps of:
-
measuring a heart rate of a user by at least one primary sensor, wherein the at least one primary sensor has a first power consumption, measuring at least one physiological factor influencing the heart rate of the user by at least one secondary sensor, wherein the at least one secondary sensor has a second power consumption which is lower than the first power consumption, managing the operation and/or power consumption of the at least one primary sensor based on information received from the at least one secondary sensor, estimating a heart rate of the user based on a model stored in a model unit and the information received from the at least one secondary sensor, and comparing the estimated heart rate with the measured heart rate so as to decrease a sampling frequency and/or measurement intensity of the primary sensor if the estimated heart rate and the measured heart rate correspond to each other.
