Method for operating multi-mode sensor device and associated apparatus

The invention relates to a method for operating a multi-mode sensor device and an associated apparatus. The present invention provides a BMD having a plurality of device modes associated with various data processing algorithms, depending on operating conditions of the device, such as exercise intensity, device placement, and/or activity type. 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 BMD are provided. In some embodiments, the process and the BMD apply time-domain analysis to data provided by sensors of the BMD when the data has a high signal (e.g., a high signal-to-noise ratio), and apply frequency-domain analysis to the data when the data has a low signal, which facilitates improved accuracy and speed of biometric data. 本申请案涉及用于操作多模式传感器装置及相关联设备的方法。本发明提供BMD，其取决于装置的操作条件而具有多个装置模式，所述操作条件例如运动强度、装置放置及/或活动类型，所述装置模式与各种数据处理算法相关联。在一些实施例中，所述BMD实施为手腕佩戴式或手臂佩戴式装置。在一些实施例中，提供用于使用所述BMD跟踪生理度量的方法。在一些实施例中，所述过程及所述BMD在由
