Multimode sensor devices
First Claim
1. A biometric monitoring device comprising:
- one or more sensors providing sensor output data comprising information about a user'"'"'s physiological activity when the biometric monitoring device is worn by the user;
a display device configured to display values of physiological metrics generated for the user; and
one or more processors configured to;
(a) operate the one or more sensors to provide the sensor output data when the biometric monitoring device is worn by the user;
(b) determine that a first portion of the sensor output data includes data indicative of the user being engaged in a first activity and that a signal strength characteristic for the first portion of the sensor output data is higher than a first threshold value, wherein the first activity is walking and/or running;
(c) update, based at least in part on the determination of (b), a heart rate metric using information obtained from a time domain analysis of the first portion of the sensor output data;
(d) determine that a second portion of the sensor output data includes data indicative of the user being engaged in a second activity and that a signal strength characteristic for the second portion of the sensor output data is less than or equal to a second threshold value, wherein the second activity is selected from the group consisting of;
elliptical machine exercise, stair machine exercise, cardio exercise machines, weight training, driving, swimming, biking, sleeping, driving, stair climbing, rock climbing, and any combination thereof;
(e) update, based at least in part on the determination of (d), the heart rate metric using information obtained from a frequency domain analysis of the second portion of the sensor output data;
(f) repeat (b) through (e) for additional portions of the sensor output data; and
(g) control the display device of the biometric monitoring device to display the heart rate metric.

Abstract
The disclosure provides BMDs that have multiple device modes depending on operational conditions of the devices, e.g., motion intensity, device placement, and/or activity type, the device modes are associated with various data processing algorithms. In some embodiments, the BMD is implemented as a wrist-worn or arm-worn device. In some embodiments, methods for tracking physiological metrics using the BMDs are provided. In some embodiments, the process and the BMD applies a time domain analysis on data provided by a sensor of the BMD when the data has a high signal (e.g., high signal-to-noise ratio), and applies a frequency domain analysis on the data when the data has a low signal, which contributes to improved accuracy and speed of biometric data.
