Abstract
A technology for a wearable medical device for monitoring medical parameters. Medical measurement data can be received at the wearable medical device from a medical measurement sensor attached to the wearable medical device or a medical measurement sensor in communication with the wearable medical device. A calibration coefficient can be determined for calibrating the wearable medical device based on the medical measurement data. The wearable medical device can be calibrated based on the calibration coefficient.
Claims19
A wearable device, comprising:
- a first sensor to measure a first physiological characteristic of a user to obtain a first set of physiological data;
- a second sensor to measure a second physiological characteristic of the user to obtain a second set of physiological data, wherein the second sensor is different than the first sensor;
- and
- a processing device to:
- identify a first data point in the first set of physiological data that is orthogonal to a second data point in the second set of physiological data;
- and
- determine a calibration coefficient for calibrating the first sensor or a measurement from the first sensor based on the first data point and the second data point;
- determine an accuracy level of the first set of physiological data;
- and
- in response to the accuracy level of the first set of physiological data being below a threshold level, calibrate the first sensor or the measurement from the first sensor based on the calibration coefficient.
A non-transitory computer-readable storage medium comprising instructions configured to cause a computing device to perform operations, the operations comprising:
- receiving, from a first sensor, a first physiological characteristic of a user to obtain a first set of physiological data, the first sensor being physically coupled to a wearable device;
- receiving, from a second sensor, a second physiological characteristic of the user to obtain a second set of physiological data, the second sensor being physically coupled to the wearable device;
- identifying a first data point in the first set of physiological data that is orthogonal to a second data point in the second set of physiological data;
- determining a unique physiological characteristic of the user based on the first set of physiological data;
- determining a calibration coefficient the sensor or measurements from the sensor for the unique physiological characteristic in view of the first data point and the second data point;
- and
- calibrating the sensor or the measurement from the sensor based on the calibration coefficient.
A method, comprising:
