Portable biometric monitoring devices and methods of operating same
First Claim
1. A portable biometric monitoring device comprising:
- housing having a physical size and shape that is adapted to couple to a limb of the user, the housing having;
a back surface that faces the limb of the user when the portable biometric monitoring device is worn on the user'"'"'s limb, anda protrusion that protrudes from the back surface, wherein the transition between the protrusion and the back surface represents a discontinuity in the profile of the back surface;
at least one band, coupled to the housing, to secure the portable biometric monitoring device to the user'"'"'s limb;
a physiological sensor, disposed in the housing, to generate data which is representative of a physiological condition of the user, the physiological sensor including;
a first light source, disposed in the housing, to generate and output light having at least a first wavelength, anda photodetector, disposed in the housing, to detect scattered light;
a first light pipe, disposed in the housing and optically coupled to the first light source, to direct or transmit light from the first light source along a predetermined path to an outer surface of the protrusion; and
processing circuitry, disposed in the housing, to calculate a heart rate of the user using data which is representative of the scattered light.

Abstract
The present inventions, in one aspect, are directed to portable biometric monitoring device including a housing having a physical size and shape that is adapted to couple to the user'"'"'s body, at least one band to secure the monitoring device to the user, a physiological sensor, disposed in the housing, to generate data which is representative of a physiological condition of the user data. The physiological sensor may include a light source to generate and output light having at least a first wavelength, and a photodetector to detect scattered light (e.g., from the user). A light pipe is disposed in the housing and optically coupled to the light source directs/transmits light therefrom along a predetermined path to an outer surface of the housing. Processing circuitry calculates a heart rate of the user using data which is representative of the scattered light.
