Abstract
Methods, systems, and devices for adjusting power consumption of a wearable device based on heart rate data are described. The method may include acquiring first physiological data from a user in accordance with a first measurement configuration associated with a first power consumption and determining a heart rate of the user based on the first physiological data. Further, the method may include comparing the heart rate to a set of heart rate ranges associated with the user and selecting a second measurement configuration associated with a second power consumption based on the heart rate of the user falling into a second heart rate range. Moreover, the method may include acquiring second physiological data in accordance with the second measurement configuration.
Core Innovation
The invention relates to wearable-device techniques for controlling battery consumption by acquiring physiological data using different sensor measurement configurations. A wearable device acquires first physiological data in accordance with a first measurement configuration associated with a first power consumption, determines a heart rate of a user based at least in part on the first physiological data, and compares the heart rate to a set of heart rate ranges associated with the user based at least in part on one or more demographic characteristics of the user.
After the comparison, the wearable device selects a second measurement configuration from the set of measurement configurations based at least in part on the heart rate of the user falling into a second heart rate range. The second measurement configuration corresponds to the second heart rate range and is associated with a second power consumption different from the first power consumption, and the wearable device acquires second physiological data in accordance with the second measurement configuration.
The documented techniques further include refining how the heart-rate ranges and measurement configurations are established and used for configuration selection. Heart rate ranges may correspond to activity-level states such as sleeping, mild activity, and intense activity, and the measurement configuration selection may include operational-parameter adjustments for sensor behavior and communication, including different sampling rate and resolution depending on the heart rate range.
Claims Coverage
The partial content includes two independent claims: a method claim and an apparatus claim. Across both, the core coverage is switching between sensor measurement configurations tied to heart-rate ranges based at least in part on demographic characteristics, where each configuration has a different associated power consumption.
Battery-aware switching of sensor measurement configurations by heart rate ranges
Acquire first physiological data from a user via one or more sensors in accordance with a first measurement configuration associated with a first power consumption; determine a heart rate based at least in part on the first physiological data; compare the heart rate to a set of heart rate ranges associated with the user based at least in part on one or more demographic characteristics; select a second measurement configuration based at least in part on the heart rate falling into a second heart rate range, where the second measurement configuration corresponds to the second heart rate range and is associated with a second power consumption different from the first power consumption; and acquire second physiological data in accordance with the second measurement configuration.
Processor-controlled battery consumption switching using heart-rate range-based configurations
Provide an apparatus with a processor, memory, and instructions executable by the processor to acquire first physiological data in accordance with a first measurement configuration associated with a first power consumption; determine a heart rate based at least in part on the first physiological data; compare the heart rate to a set of heart rate ranges associated with the user based at least in part on one or more demographic characteristics, where the set corresponds to a set of measurement configurations including the first measurement configuration; select a second measurement configuration based at least in part on the heart rate falling into a second heart rate range, where the second measurement configuration corresponds to the second heart rate range and is associated with a second power consumption different from the first power consumption; and acquire second physiological data in accordance with the second measurement configuration.
The claims cover both a method and an apparatus that control wearable-device battery consumption by determining heart rate from physiological data, comparing the heart rate to demographic-characteristic-based heart rate ranges, and selecting a corresponding measurement configuration having a different power consumption to acquire subsequent physiological data.
