Personal monitoring system and method

摘要

A personal monitoring device of the present disclosure has a sensing device that detects motion of a user and a global positioning system (GPS) that executes queries to identify a current location of the user. In addition, the device has logic that stores motion data indicative of motion of the user detected by the sensing device and adjusts a rate of location queries executed by the GPS based upon the stored motion data indicative of motion.

主权项

1. A personal monitoring device for a user configured for avoiding using a power intensive resource when it is estimated that the user's location has not changed appreciably, comprising:
a first sensing device configured for continuously measuring movement of the user; a global positioning system (GPS) configured for periodically executing queries to identify a current location of the user; a processor electrically coupled to the first sensing device and to the GPS and configured for storing motion data indicative of motion of the user detected by the first sensing device in memory, wherein the memory is electrically coupled to the processor, the processor further configured for disallowing the GPS from periodically executing queries and for estimating the current location of the user based upon the stored data indicative of motion, wherein when the estimating indicates that the user has moved a certain distance from a previous location, the processor is further configured to allow the GPS to execute queries, wherein the processor is further configured for storing location data indicative of the last known location of the user as obtained by the GPS.
