GPS power conservation using environmental data
First Claim
1. A biometric monitoring device configured to be worn on a person, the device comprising:
- a global positioning system (GPS) receiver;
a motion sensor;
a biometric sensor configured to generate body characteristic data; and
a controller, communicatively coupled to the GPS receiver and the biometric sensor, including at least one processor and a non-transitory computer readable medium, the non-transitory computer readable medium having computer-executable instructions stored thereon which, when executed, cause the at least one processor to;
determine a motion state of the device based on motion data received from the motion sensor, andset a frequency with which the GPS receiver obtains positional fixes based on the motion state and the body characteristic data,wherein the frequency of obtaining positional fixes comprises a time interval between which the GPS receiver obtains positional fixes of the device, the controller being configured to set the frequency at one of a first level and a second level, andwherein the second level has a lower frequency with which the GPS receiver obtains the positional fixes than the first level, the second level indicative of a greater time interval between positional fixes than the first level.

Abstract
Biometric monitoring devices, including various technologies that may be implemented in such devices, are discussed herein. Additionally, techniques, systems, and apparatuses are discussed herein for providing power-conserving techniques and systems for efficiently utilizing a GPS receiver are described. The positional fix frequency of the GPS receiver may, according to some implementations, be modified or adjusted between various levels according to data from one or more non-GPS sensors. Such non-GPS sensors may include, for example, ambient light intensity or spectrum sensors, accelerometers, gyroscopes, magnetometers, heart rate sensors, galvanic skin response sensors, infrared sensors, etc.
