Abstract

Some embodiments provide a wearable fitness monitoring device including a motion sensor and a photoplethysmographic (PPG) sensor. The PPG sensor includes (i) a periodic light source, (ii) a photo detector, and (iii) circuitry determining a user's heart rate from an output of the photo detector. Some embodiments provide methods for operating a heart rate monitor of a wearable fitness monitoring device to measure one or more characteristics of a heartbeat waveform. Some embodiments provide methods for operating the wearable fitness monitoring device in a low power state when the device determines that the device is not worn by a user. Some embodiments provide methods for operating the wearable fitness monitoring device in a normal power state when the device determines that the device is worn by a user.

Description

technical field Background technique [0001] Recent consumer concerns about personal health have resulted in a variety of personal health monitoring devices being offered on the market. Until recently, such devices tended to be complicated to use and were usually designed for one activity, such as bicycle touring computers. [0002] Recent advances in the miniaturization of sensors, electronics, and power supplies have allowed the size of personal health monitoring devices (also referred to herein as "biometric tracking" or "biometric monitoring" devices) to provide . For example, the Fitbit Ultra is a biometric monitoring device approximately 2 inches long, 0.75 inches wide, and 0.5 inches deep; it has a pixelated display, battery, sensors, wireless communication capabilities, power and interface buttons packed into this small volume , and an integrated clip for attaching the device to a pocket or other part of clothing. [0003] The present invention provides methods and...
