Multimode sensor devices
First Claim
1. A biometric monitoring device comprising:
- one or more motion sensors providing motion data;
a display device configured to present step count metrics; and
one or more processors configured to;
operate the one or more motion sensors when the biometric monitoring device is in motion;
control the one or more motion sensors to generate a set of motion data indicative of movements of a user;
apply a frequency domain analysis to the set of motion data to obtain a first measure of a periodic component of the set of motion data;
apply a time domain analysis to the set of motion data to obtain a second measure of the periodic component of the set of motion data;
determine that a signal power of the set of motion data is lower than a threshold;
select, based on determining that the signal power is lower than the threshold, the first measure of the periodic component over the second measure of the periodic component;
update a step count metric of the user using the first measure of the periodic component; and
control the display device of the biometric monitoring device to display the updated step count 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 or 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.
